Nodes

Detailed Description

Classes: class SoNodeList
The SoNodeList class is a container for pointers to SoNode objects.; As this class inherits SoBaseList, referencing and dereferencing will default be done on the objects at append(), remove(), insert() etc. "
class SoAnnotation: The SoAnnotation node draws all its child geometry on top of other geometry.; This group-type node uses delayed rendering in combination with Zbuffer disabling to let its children transparently render their
geometry on top of the other geometry in the scene. "
class SoAntiSquish: The SoAntiSquish class is used to reset to uniform scaling.; When traversed, this node replaces the scale vector of the matrix with uniform values, based on one of the SoAntiSquish::Sizing strategies. "
class SoArray: The SoArray class is a group node for setting up regular arrays of subgraphs.; SoArray presents a convenient way of duplicating a node (typically a shape node) or a complete subgraph in 1 to 3 dimensions. "
class SoAsciiText: The SoAsciiText class renders flat 3D text.; The text is rendered using 3D polygon geometry. "
class SoBaseColor: The SoBaseColor class provides a node type for convenient setting of the base material color.; If you want to just set the diffuse color of the following geometry,
you can use this node for simplicity. "
class SoBlinker: The SoBlinker class is a cycling switch node.; This switch node cycles its children SoBlinker::speed number of times per second. If the node has only one child, it will be cycled on and
off. Cycling can be turned off using the SoBlinker::on field, and the node then behaves like a normal SoSwitch node. "
class SoBumpMap: The SoBumpMap class is used to map a bump map onto subsequent shapes.; SoBumpMap has support for two types of maps. If the image is a three component (RGB) image, it will be treated as a normal map, where the
red image component equals the X normal component, green equals Y, and blue is Z. See
http://www.paulsprojects.net/tutorials/simplebump/simplebump.html for a nice introduction about bump mapping and normal maps. "
class SoBumpMapCoordinate: The SoBumpMapCoordinate class is a node for providing bump map coordinates to shape nodes.; When encountering nodes of this type during traversal, the coordinates it contains will be put on the state stack for later use by shape
nodes. The bump map coordinates can be used to specify explicit
coordinates for a bump map. The SoBumpMap node is used to specify a bump map for the shape nodes. "
class SoBumpMapTransform: The SoBumpMapTransform class is used to define 2D bump map transformations.; Bump maps applied to shapes in the scene can be transformed by
'prefixing' in the state with instances of this node type.
Translations, rotations and scaling in 2D can all be done. "
class SoCallback: The SoCallback class is a node type which provides a means of setting callback hooks in the scene graph.; By inserting SoCallback nodes in a scene graph, the application programmer can set up functions to be executed at certain points in the traversal. "
class SoCamera: The SoCamera class is the abstract base class for camera definition nodes.; To be able to view a scene, one needs to have a camera in the scene
graph. A camera node will set up the projection and viewing matrices
for rendering of the geometry in the scene. "
class SoClipPlane: The SoClipPlane class is a node type for specifying clipping planes.; A scene graph without any SoClipPlane nodes uses six clipping planes to define the viewing frustum: top, bottom, left, right, near and far. If you want extra clipping planes for 'slicing' the visible geometry, you can do that by using nodes of this type. Geometry on the back side of
the clipping plane is clipped away. "
class SoColorIndex: The SoColorIndex class is used to specify color indices for subsequent shapes.; This node should only be used in OpenGL color-index mode, and only when the current light model is set to SoLightModel::BASE_COLOR. "
class SoComplexity: The SoComplexity class is a node type which is used to set the tradeoff between quality and performance.; By inserting SoComplexity nodes in the scene graph, you can control the accuracy by which complex shapes are rendered and the quality of the
texture mapping used for geometry in the scene. "
class SoCone: The SoCone class is for rendering cone shapes.; Insert a cone shape into the scenegraph. The cone is rendered with the current material, texture and drawstyle settings (if any, otherwise the default settings are used). "
class SoCoordinate3: The SoCoordinate3 class is a node for providing coordinates to shape nodes.; When encountering nodes of this type during traversal, the coordinates it contains will be put on the state stack for later use by shape nodes of types which needs coordinate sets (like SoFaceSet nodes or SoPointSet nodes). "
class SoCoordinate4: The SoCoordinate4 class is a node for providing coordinates to shape nodes.; When encountering nodes of this type during traversal, the coordinates it contains will be put on the statestack for later use by shape nodes of types which needs coordinate sets (like SoFaceSet nodes or SoPointSet nodes). "
class SoCube: The SoCube class is for rendering cubes.; Insert a cube shape into the scenegraph. The cube is rendered with the current material, texture and drawstyle settings (if any, otherwise the default settings are used). "
class SoCylinder: The SoCylinder class is for rendering cylinder shapes.; Insert a cylinder shape into the scenegraph. The cylinder is rendered
with the current material, texture and drawstyle settings (if any,
otherwise the default settings are used). "
class SoDirectionalLight: The SoDirectionalLight class is a node type for specifying directional light sources.; A directional light source provides a model of light sources which are at infinite distance from the geometry it illuminates, thereby having
no set position and consisting of an infinite volume of parallel rays. "
class SoDrawStyle: The SoDrawStyle class specificies common rendering properties for shapes.; Use SoDrawStyle nodes to influence how shape nodes following them in the scenegraph will be rendered. This node type have fields to help
decide how certain aspects of point-based shapes, line-based shapes and filled shape primitives are rendered. "
class SoEnvironment: The SoEnvironment class is a node for specifying global rendering parameters.; This node type provides the application programmer with the ability to set global parameters influencing lighting and fog. "
class SoEventCallback: The SoEventCallback class provides functionality for catching events.; Use SoEventCallback nodes in the scenegraph for catching user interaction events with the scenegraph's render canvas. "
class SoExtSelection: The SoExtSelection class can be used for extended selection functionality.; This class enables you to select geometry by specifying a lasso (a
polygon) or a rectangle on screen. When objects are selected, you'll
receive the same callbacks as for the SoSelection node. "
class SoFaceSet: The SoFaceSet class is used to render and organize non-indexed polygonal face data.; Faces are specified using the numVertices field. Coordinates, normals, materials and texture coordinates are fetched in order from the current state or from the vertexProperty node if set. For example, if
numVertices is set to [3, 4, 5, 3], this node would specify a triangle from coordinates 0, 1 and 2, a quad from coordinates 3, 4, 5 and 6, a
polygon from coordinates 7, 8, 9, 10 and 11 and finally a triangle from coordinates 12, 13, 14. "
class SoFile: The SoFile class is node container for another model file.; This node provides a way to split your models into a set of 'component' models to include into larger 'master' files. "
class SoFont: The SoFont class is an appearance node for setting fonts.; Successive text rendering nodes (like SoText2, SoText3, SoAsciiText, etc) will use the font specified from an SoFont node when visualizing text. "
class SoFontStyle: The SoFontStyle class changes the appearance of fonts for text rendering nodes.; Successive text rendering nodes will use fonts with the style settings of this node, if a font with the given settings can be found and loaded from the system. "
class SoGroup: The SoGroup class is a node which managed other node instances.; The internal scene data structures in Coin are managed as directed
graphs. The graphs are built by setting up a hierarchy through the use of group nodes (either of this type, or from subclasses like
SoSeparator) which is then traversed when applying actions (like SoGLRenderAction) to it. "
class SoImage: The SoImage class draws a 2D image on the viewport.; An image can be specified either by using the image field, or by
specifying a filename. If width and or height is specified, the image
will be resized to match those values before it is displayed. "
class SoIndexedFaceSet: The SoIndexedFaceSet class is used to handle generic indexed facesets.; Faces are specified using the coordIndex field. Each face must be
terminated by a negative (-1) index. Coordinates, normals, materials
and texture coordinates from the current state (or from the
vertexProperty node if set), can be indexed to create triangles, quads or polygons. "
class SoIndexedLineSet: The SoIndexedLineSet class is used to render and otherwise represent indexed lines.; The indexed counterpart of SoLineSet. Lines can specified using indices for coordinates, normals, materials and texture coordinates. "
class SoIndexedNurbsCurve: The SoIndexedNurbsCurve class is a node for representing smooth curves.; Explaining NURBS is beyond the scope of this documentation. If you are unfamiliar with the principles of representing smooth curves and
surfaces when doing 3D visualization, we recommend finding a good book on the subject. "
class SoIndexedNurbsSurface: The SoIndexedNurbsSurface class can be used to render NURBS surfaces.; It is very similar to the SoNurbsSurface class, but controlpoints can be specified using indices. "
class SoIndexedShape: The SoIndexedShape class is the superclass for all indexed vertex shapes.; This is an abstract class which contains storage for four fields for
indices to coordinates, normals, materials and texture coordinates for it's subclasses. "
class SoIndexedTriangleStripSet: The SoIndexedTriangleStripSet class keeps data for rendering and otherwise representing triangle strips.; Use nodes of this type as an effective way of drawing triangles which
are strung together. "
class SoInfo: The SoInfo class is a node for holding text information.; This is simply a placeholder for textual information about a scene.
Typically used for specifying author and copyright information in
Inventor format files, but can also be used for other purposes, of
course. "
class SoLOD: The SoLOD class is used to choose a child based distance between viewer and object.; The class documentation for the SoLOD node class would be similar enough to that of SoLevelOfDetail that we will refer you to look at that one first. It will explain the general principles of what a levelof-detail mechanism is, and why and how to use it. "
class SoLabel: The SoLabel class is a node for holding label information in a scene graph.; Use this node as a convenient way of labeling nodes or subgraphs within a scene graph. "
class SoLevelOfDetail: The SoLevelOfDetail class is used to choose a child based on projected size.; A level-of-detail mechanism is typically used by application
programmers to assist the library in speeding up the rendering. "
class SoLight: The SoLight class is the base class for light emitting nodes.; This node type is abstract and does not in itself provide any light
sources to the scene, you need to use one of its subclasses. "
class SoLightModel: The SoLightModel class is a node for specifying the model for geometry lighting.; Use nodes of this type to set up how lighting should affect subsequent geometry in the scene. "
class SoLineSet: The SoLineSet class is used to render and organize non-indexed polylines.; Polylines are specified using the numVertices field. Coordinates,
normals, materials and texture coordinates are fetched in order from
the current state or from the vertexProperty node if set. For example, if numVertices is set to [3, 4, 2], this node would specify a line
through coordinates 0, 1 and 2, a line through coordinates 3, 4, 5 and 6, and finally a single line segment between coordinates 7 and 8. "
class SoLinearProfile: The SoLinearProfile class is a node for specifying linear profile curves.; Use nodes of this type if you want to set up profiles that are simply
straight lines connected by control points. "
class SoListener: The SoListener class defines listener attributes used when rendering sound.; When rendering geometry, one needs to have a camera defining certain
attributes related to vieweing. The SoListener plays a similar role when it comes to rendering audio. "
class SoLocateHighlight: The SoLocateHighlight class highlights geometry under the cursor.; Note: this node is supposed to draw to the front buffer. However, in
Coin we always draw to the back buffer, forcing a scene redraw whenever a highlight state changes. "
class SoMarkerSet: The SoMarkerSet class displays a set of 2D bitmap markers in 3D.; This node uses the coordinates currently on the state (or in the
vertexProperty field) in order. The numPoints field specifies the
number of points in the set. "
class SoMaterial: The SoMaterial class is a node type for setting up material values for scene geometry.; After traversing an SoMaterial node, subsequent shape nodes with geometry in the scene graph will use values from the material 'pool' of the traversal state set up from nodes of this type. "

model transformation matrix. "
class SoMultipleCopy: The SoMultipleCopy class redraws it's children multiple times at different transformations.; The SoMultipleCopy group node duplicates it's children nodes / subgraphs without using additional memory resources. "
class SoNode: The SoNode class is the base class for nodes used in scene graphs.; Coin is a retained mode 3D visualization library (built on top of the immediate mode OpenGL library). 'Retained mode' means that instead of passing commands to draw graphics primitives directly to the renderer, you build up data structures which are rendered by the library on
demand. "
class SoNonIndexedShape: The SoNonIndexedShape class is the superclass for all non-indexed vertex based shapes.; It contains the (now obsoleted) startIndex field and a convenience
method for calculating the bounding box. "
class SoNormal: The SoNormal class is a node for providing normals to the state.; Coin will automatically calculate normals for you if no SoNormal nodes are present in the scene graph, but explicitly setting normals is
useful for at least two purposes: 1) a potential increase in
performance, 2) you can calculate and use 'incorrect' normals to do
various special effects. "
class SoNormalBinding: The SoNormalBinding class is a node for specifying normal vector bindings.; Use nodes of this type to specify how to map normal vectors from
SoNormal nodes in the scene graph to shape nodes. "
class SoNurbsCurve: The SoNurbsCurve class is a node for representing smooth curves.; A general explanation of NURBS is beyond the scope of the Coin
documentation. For detailed information, refer to the specialized

Historical Perspective' by David F. Rogers). A basic overview of curve and surface rendering using NURBS can be found in chapter 8 of 'The
Inventor Mentor'. "
class SoNurbsProfile: The SoNurbsProfile class is a node for specifying smooth profile curves.; Use nodes of this type if you want to set up profiles that are smooth
curves. "
class SoNurbsSurface: The SoNurbsSurface class is used to render smooth surfaces.; A general explanation of NURBS is beyond the scope of the Coin
documentation. For detailed information, refer to the specialized
literature on the topic (for example 'An Introduction to NURBS: With
Historical Perspective' by David F. Rogers). A basic overview of curve and surface rendering using NURBS can be found in chapter 8 of 'The
Inventor Mentor'. "
class SoOrthographicCamera: The SoOrthographicCamera class defines a camera node with orthographic rendering.; Orthographic rendering will not give a particularly realistic
impression of the scene, but non-realistic rendering is for various
reasons widely used in applications for e.g. Computer Aided Design. "
class SoPackedColor: The SoPackedColor class is a node for setting diffuse and transparency material values.; This node provides a convenient way of setting diffuse colors and
transparency values with packed 32-bit RGBA vectors. "
class SoPathSwitch: The SoPathSwitch class traverses only when current path matches a configurable path.; FILE FORMAT/DEFAULTS:. "
class SoPendulum: The SoPendulum class is used to create oscillating rotations.; A smooth transition between rotation0 and rotation1 is created using a cosine function. In the beginning of the cycle, rotation0 is used.
Halfway through the cycle, the resulting rotation equals rotation1, and at the end of the cycle, we're at rotation0 again. "
class SoPerspectiveCamera: The SoPerspectiveCamera class defines a camera node with perspective rendering.; For realistic looking 3D scene, the geometry should be rendered with
perspective calculations. Use this camera type to accomplish this. "
class SoPickStyle: The SoPickStyle class is a node for setting up how to do picking.; By default, all geometry in a scene is available for picking. Upon
writing applications with interaction possibilities, this is often not what you want. To exclude parts of the scene graph from pick actions,
use the SoPickStyle::UNPICKABLE. "
class SoPointLight: The SoPointLight class is a node type for light sources.; Pointlights emits light equally in all directions from a specified 3D
location. "
class SoPointSet: The SoPointSet class is used to display a set of 3D points.; This node either uses the coordinates currently on the state (typically set up by a leading SoCoordinate3 node in the scenegraph) or from a SoVertexProperty node attached to this node to render a set of 3D points. "
class SoPolygonOffset: The SoPolygonOffset class is a node type for 'layering' rendering primitives.; A common problem with realtime 3D rendering systems is that rendered
primitives which are at approximately the same depth with regard to the camera viewpoint will appear to flicker. I.e.: from one angle one
primitive will appear to be closer, while at another angle, another
primitive will appear closer. When this happens, the rendered graphics at that part of the scene will of course look a lot less visually
pleasing. "
class SoProfile: The SoProfile class is the abstract superclass for profile definitions.; Node subclasses of SoProfile specifies profiles for extruded 3D text and nurbs surface data. "
class SoProfileCoordinate2: The SoProfileCoordinate2 class is a node specifying a set of 2D coordinates for profiles.; Use nodes of this type to provide coordinates to profiles. "

class SoResetTransform: The SoResetTransform class is a node type which makes it possible to 'nullify' state during traversal.; SoResetTransform is useful for setting up geometry in the scene graph which will not be influenced by the transformation nodes before it
during traversal. "
class SoRotation: The SoRotation class specifies a rotation transformation.; Use nodes of this class type to re-orient geometry data within the
scene graph. "
class SoRotationXYZ: The SoRotationXYZ class is a node type for specifying rotation around a particular axis.; Application programmers can use nodes of this type instead of
SoRotation nodes for simplicity and clarity if the rotation will only happen around one particular axis. "
class SoRotor: The SoRotor class is a node used to animate rotations.; Insert this node in your hierarchy to apply a continuous rotation to
some geometry. Since this node inherits the SoRotation node, rotation is restricted around the axis specified in the rotation field. "
class SoScale: The SoScale class is a node type for scaling scene graph geometry.; Use nodes of this type to apply scaling operations during scenegraph
traversals for e.g. rendering. Scale values are specified in a triplevalue vector, with one scale factor for each of the 3 principal axes. "

below the SoSelection node. "
class SoSeparator: The SoSeparator class is a state-preserving group node.; Subgraphs parented by SoSeparator nodes will not affect the state, as they push and pop the traversal state before and after traversal of its children. "

the scene graph should be drawn. "
class SoShuttle: The SoShuttle class is used to oscillate between two translations.; A smooth transition between translation0 and translation1 is created
using a cosine function. In the beginning of the cycle, translation0 is used. Halfway through the cycle, the resulting translation equals
translation1, and at the end of the cycle, we're at translation0 again. "
class SoSphere: The SoSphere class is for rendering sphere shapes.; Renders a sphere with the size given by the SoSphere::radius field. The sphere is rendered with the current material, texture and drawstyle
settings (if any, otherwise the default settings are used). "
class SoSpotLight: The SoSpotLight class is a node type for light sources with a cone shaped lightvolume.; Spotlights are light sources with a position and a direction. They can be thought of as a pointlight with a lampshade. "
class SoSurroundScale: The SoSurroundScale class is used to automatically scale geometry to surround other geometry.; This node calculates a transformation (a translation and a scale) which will, when the node is traversed, be appended to the current model
matrix, making a default cube placed directly to the right of this node in the graph surround geometry to the right of the container branch
this node is on. The container is specified by the field
SoSurroundScale::numNodesUpToContainer. "
class SoSwitch: The SoSwitch class is a group node which selects one child subgraph for traversal.; Which child to traverse is controlled by the application programmer by using the SoSwitch::whichChild field. In addition to picking out a single child for traversal, it is also possible to flip all children on or off for traversal. "
class SoText2: The SoText2 class is a node type for visualizing 2D text aligned with the camera plane.; SoText2 text is not scaled according to the distance from the camera, and is not influenced by rotation or scaling as 3D primitives are. If
these are properties that you want the text to have, you should instead use an SoText3 or SoAsciiText node. "
class SoText3: The SoText3 class renders extruded 3D text.; Render text as 3D geometry. "
class SoTexture2: The SoTexture2 class is used to map a 2D texture onto subsequent geometry in the scenegraph.; Shape nodes within the scope of SoTexture2 nodes in the scenegraph (ie below the same SoSeparator and to the righthand side of the SoTexture2) will have the texture applied according to each shape type's individual characteristics. See the documentation of the various shape types
(SoFaceSet, SoCube, SoSphere, etc etc) for information about the specifics of how the textures will be applied. "
class SoTexture2Transform: The SoTexture2Transform class is used to define 2D texture transformations.; Textures applied to shapes in the scene can be transformed by

See the documentation of the various shape types
(SoFaceSet, SoCube, SoSphere, etc etc) for information about the specifics of how the textures will be applied. An SoTexture3 node will override any previous encountered SoTexture2 nodes and vice versa. Mixing of SoTexture3 and SoTextureCoordinate2 (or the other way around) is legal, but the third texture coordinate component will be ignored
(set to 0.0). "
class SoTexture3Transform: The SoTexture3Transform class is used to define 3D texture transformations.; Textures applied to shapes in the scene can be transformed by
'prefixing' in the state with instances of this node type.
Translations, rotations and scaling in 3D can all be done. "
class SoTextureCombine: The SoTextureCombine class is a node for setting texture combine functions.; This node is more or less an exact mapping of the OpenGL
ARB_texture_env_combine extension (included in OpenGL in OpenGL v1.3). See http://oss.sgi.com/projects/oglsample/registry/ARB/texture_env_combine.txt for more information about this extension. "
class SoTextureCoordinate2: The SoTextureCoordinate2 class contains a set of coordinates for the mapping of 2D textures.; When encountering nodes of this type during traversal, the coordinates it contains will be put on the state stack. Some shape nodes (for
instance SoIndexedFaceSet, among many others) can then use these coordinates for explicit, detailed control of how textures are mapped
to it's surfaces. "
class SoTextureCoordinate3: The SoTextureCoordinate3 class contains a set of coordinates for the mapping of 2D textures.; When encountering nodes of this type during traversal, the coordinates it contains will be put on the state stack. Some shape nodes can then
use these coordinates for explicit, detailed control of how 3D textures are mapped. "
class SoTextureCoordinateBinding: The SoTextureCoordinateBinding class says how texture coordinates should be bound to shapes.; SoTextureCoordinateBinding binds current coordinates to subsequent shapes by using either per vertex or per indexed vertex binding. "
class SoTextureCoordinateCube: The SoTextureCoordinateCube class autogenerates cubemapped texture coordinated for shapes.; The cube used for reference when mapping is the boundingbox for the
shape. "
class SoTextureCoordinateCylinder: The SoTextureCoordinateCylinder class autogenerates cylinder mapped texture coordinated for shapes.; FILE FORMAT/DEFAULTS:. "
class SoTextureCoordinateDefault: The SoTextureCoordinateDefault class removes texture coordinates from the state.; Shapes below this node in the scenegraph will have to use its default
texture coordinates as SoTextureCoordinateDefault cleans out all previously defined texture coordinates and texture coordinate
functions. "
class SoTextureCoordinateEnvironment: The SoTextureCoordinateEnvironment class generates texture coordinates by projecting onto a surrounding texture.; The texture specifying the enviroment will be mapped around the
scenegraph below this node using a sphere. The texture will be mapped
onto the scenegraph taking camera position into account. This will lead to an object reflecting its enviroment. "
class SoTextureCoordinateFunction: The SoTextureCoordinateFunction class is an abstract base class for texture coordinate generating nodes; Classes reimplementing SoTextureCoordinateFunction generate texture coordinates by projecting object space surface points using some
function. "
class SoTextureCoordinatePlane: The SoTextureCoordinatePlane class generates texture coordinates by projecting onto a plane.; SoTextureCoordinatePlane is used for generating texture coordinates by projecting the object onto a texture plane. The s and t texture
coordinates are computed as the distance from the origin to the
projected point, in the respective directions. The texture plane is
specified using two direction vectors, given as
SoTextureCoordinatePlane::directionS and SoTextureCoordinatePlane::directionT in object space coordinates. The length of the vector determines the repeat interval of the texture per unit length. "

class SoTextureCubeMap: The SoTextureCubeMap class is used to map a cube map onto subsequent shape nodes.; Shape nodes within the scope of SoTextureCubeMap nodes in the scenegraph (ie below the same SoSeparator and to the righthand side of the SoTextureCubeMap) will have the texture applied according to each shape type's individual characteristics. See the documentation of the
various shape types (SoFaceSet, SoCube, SoSphere, etc etc) for information about the specifics of how the textures will be applied. "
class SoTextureScalePolicy: The SoTextureScalePolicy class is a node for controlling the texture scale policy.; If a texture map is of size != 2^n, it must be scaled before OpenGL can handle it. This node enables you to control how/if textures are scaled before it is sent to OpenGL. "
class SoTextureUnit: The SoTextureUnit class is a node for setting the active texture unit.; When an SoTextureUnit node is inserted into the scene graph, all subsequent texture nodes (SoTexture2, SoTextureCoordinate2, SoTextureCoordinate3, SoTexture2Transform, SoTexture3Transform, SoTextureCoordinateEnvironment, and SoTextureCoordinatePlane) will affect the texture unit set in the unit field. "
class SoTransform: The SoTransform class is the 'all-purpose' transformation node type.; Like SoMatrixTransform, nodes of this type gives the application programmer maximum flexibility when specifying geometry transformations in a scene graph. If you want to set and keep the various components of the transformation matrix in separate entities, this node type is
preferable, though. "
class SoTransformSeparator: The SoTransformSeparator class is a group node preserving the current transformations.; This node works like the SoSeparator group node, except that it only stores and restores the current model matrix transformation. Other
appearance settings, like materials, textures, cameras, lights, etc,
will affect the remaining parts of the scenegraph after traversal, just like as for the SoGroup node. "
class SoTransformation: The SoTransformation class is the abstract base class for transformation nodes.; To position and orient geometry within the 3D world space, various node types for transformations are used. These nodes all inherit the
SoTransformation base class. "
class SoTranslation: The SoTranslation class is a node type for specifying geometry translations.; For simply translating some geometry in a scene graph, you can use this node type. "
class SoTransparencyType: The SoTransparencyType class is a node for setting the transparency type for shapes.; In earlier versions of Coin/Open Inventor it was only possible to set
the transparency mode globally for an entire scene graph, which could
be inconvenient if different transparency types was wanted for
different shapes. "
class SoTriangleStripSet: The SoTriangleStripSet class is used to render and control non-indexed triangle strips.; Triangle strips are specified using the numVertices field. "
class SoUnits: The SoUnits class is a node for setting unit types.; Even though Coin doesn't care what units you are using in your scene
graph per se, there's an advantage to using SoUnits nodes: you have a way to split your scene graph into different 'conceptual' parts. "
class SoVertexProperty: The SoVertexProperty class collects the functionality of various appearance nodes.; Instead of reading data from the current state stack of the scenegraph traversal, nodes inheriting SoVertexShape can be set up with an SoVertexProperty node in the SoVertexShape::vertexProperty field. Coordinates, normals, texture coordinates and material / color
information will then be fetched from the vertexshape's
SoVertexProperty node instead of from the state stack. "
class SoVertexShader: The SoVertexShader class is used for setting up vertex shader programs.; See Shaders in Coin for more information on how to set up a scene graph with shaders. "
class SoVertexShape: The SoVertexShape class is the superclass for all vertex based shapes.; Basically, every polygon-, line- or point-based shape will inherit this class. It contains methods for organizing the normal cache, and also
holds the SoVertexShape::vertexProperty field which can be used to set vertex data inside the node. "
class SoWWWAnchor: The SoWWWAnchor class adds URL callbacks to the highlighted geometry.; In addition to highlighting geometry under the cursor, the application programmer can set callbacks. It is possible to set one callback for
picking, the fetch callback, and one callback for highlighting. "

supplying a callback to a function which will fetch the data of the
URL. "
