The SoVRMLIndexedShape class is a superclass for geometry that use indexes.
SoVRMLIndexedShape::SoVRMLIndexedShape | ( | void | ) | [protected] |
Constructor.
SoVRMLIndexedShape::~SoVRMLIndexedShape | ( | ) | [protected, virtual] |
Destructor.
void SoVRMLIndexedShape::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 SoVRMLVertexShape.
Reimplemented in SoVRMLIndexedFaceSet.
void SoVRMLIndexedShape::notify | ( | SoNotList * | l | ) | [protected, virtual] |
Notifies all auditors for this instance when changes are made.
Reimplemented from SoVRMLVertexShape.
void SoVRMLIndexedShape::computeBBox | ( | SoAction * | action, | |
SbBox3f & | box, | |||
SbVec3f & | center | |||
) | [protected, virtual] |
Implemented by SoShape subclasses to let the SoShape superclass know the exact size and weighted center point of the shape's bounding box.
The bounding box and center point should be calculated and returned in the local coordinate system.
The method implements action behavior for shape nodes for SoGetBoundingBoxAction. It is invoked from SoShape::getBoundingBox(). (Subclasses should not override SoNode::getBoundingBox().)
The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function entry.
Implements SoShape.

Convenience method that will fetch data needed for rendering or generating primitives. Takes care of normal cache.
The coordinate index array.
The color index array.
The normal index array.
The texture coordinate index array.
