sotexturecoordinatenormalmap(3)
NAME
SoTextureCoordinateNormalMap - The SoTextureCoordinateNormalMap 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.

Detailed Description
The SoTextureCoordinateNormalMap 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.
- Here is a scenegraph example showing how enviroment mapping can be
applied to an object: - Inventor V2.1 ascii
- Separator {
- Texture2 { filename 'ocean.jpg' # the enviroment, in this case ocean }
- TextureCoordinateNormalMap {}
Cube {} # the enviromentally mapped object }- FILE FORMAT/DEFAULTS:
TextureCoordinateNormalMap {
}

Member Function Documentation
- SoType SoTextureCoordinateNormalMap::getClassTypeId (void) [static]
- This static method returns the SoType object associated with objects of this class.
- Reimplemented from SoTextureCoordinateFunction.
- SoType SoTextureCoordinateNormalMap::getTypeId (void) const [virtual]
- Returns the type identification of an object derived from a class
inheriting SoBase. This is used for run-time type checking and 'downward' casting. - Usage example:
void foo(SoNode * node)
{if (node->getTypeId() == SoFile::getClassTypeId()) {SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type}} - For application programmers wanting to extend the library with new
nodes, engines, nodekits, draggers or others: this method needs to be
overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually
accomplished by using the pre-defined macros available through for
instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and
SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on. - For more information on writing Coin extensions, see the class
documentation of the toplevel superclasses for the various class
groups. - Reimplemented from SoTextureCoordinateFunction.
- const SoFieldData ** SoTextureCoordinateNormalMap::getFieldDataPtr (void)
- [static, protected]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. - Reimplemented from SoTextureCoordinateFunction.
- const SoFieldData * SoTextureCoordinateNormalMap::getFieldData (void) const
- [protected, virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. - Reimplemented from SoTextureCoordinateFunction.
- void SoTextureCoordinateNormalMap::initClass (void) [static]
- Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
- Reimplemented from SoTextureCoordinateFunction.
- void SoTextureCoordinateNormalMap::doAction (SoAction * action) [virtual]
- This function performs the typical operation of a node for any action.
- Reimplemented from SoNode.
- void SoTextureCoordinateNormalMap::GLRender (SoGLRenderAction * action)
- [virtual]
Action method for the SoGLRenderAction. - This is called during rendering traversals. Nodes influencing the
rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. - Reimplemented from SoNode.
- void SoTextureCoordinateNormalMap::pick (SoPickAction * action) [virtual]
- Action method for SoPickAction.
- Does common processing for SoPickAction action instances.
- Reimplemented from SoNode.
- void SoTextureCoordinateNormalMap::callback (SoCallbackAction * action)
- [virtual]
Action method for SoCallbackAction. - Simply updates the state according to how the node behaves for the
render action, so the application programmer can use the
SoCallbackAction for extracting information about the scene graph. - Reimplemented from SoNode.
