NAME
SoGLDisplayList - The SoGLDisplayList class stores and manages OpenGL
display lists.
The TEXTURE_OBJECT type is not directly supported in Coin. We handle
textures differently in a more flexible class called SoGLImage, which
also stores some information about the texture used when rendering. Old
code which use this element should not stop working though. The texture
object extension will just not be used, and the texture will be stored
in a display list instead.

Constructor & Destructor Documentation
- SoGLDisplayList::SoGLDisplayList (SoState * state, Type type, int allocnum
- = 1, SbBool mipmaptexobj = FALSE) Constructor.
Member Function Documentation
- void SoGLDisplayList::ref (void)
- Increase reference count for this display list/texture object.
- void SoGLDisplayList::unref (SoState * state = NULL)
- Decrease reference count for this instance. When reference count
reaches 0, the instence is deleted. - void SoGLDisplayList::open (SoState * state, int index = 0)
- Open this display list/texture object.
- void SoGLDisplayList::close (SoState * state)
- Close this display list/texture object.
- void SoGLDisplayList::call (SoState * state, int index = 0)
- Execute this display list/texture object.
- void SoGLDisplayList::addDependency (SoState * state)
- Create a dependency on the display list.
- SbBool SoGLDisplayList::isMipMapTextureObject (void) const
- Returns whether the texture object stored in this instance was created with mipmap data. This method is an extension versus the Open Inventor API.
- SoGLDisplayList::Type SoGLDisplayList::getType (void) const
- Return type. Display list or texture object.
- int SoGLDisplayList::getNumAllocated (void) const
- Return number of display lists/texture objects allocated.
- unsigned int SoGLDisplayList::getFirstIndex (void) const
- Return first GL index for this display list.
- int SoGLDisplayList::getContext (void) const
- Return an id for the current context.
- void SoGLDisplayList::setTextureTarget (int target)
- Sets the texture object target
- Since:
Coin 2.5
- int SoGLDisplayList::getTextureTarget (void) const
- Returns the texture target
- Since:
Coin 2.5
