Member Function Documentation

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   list [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.

SbBool SoVRMLIndexedShape::getVertexData SoState   state,
const SoCoordinateElement *&    coords,
const SbVec3f *&    normals,
const int32_t *&    cindices,
const int32_t *&    nindices,
const int32_t *&    tindices,
const int32_t *&    mindices,
int &    numcindices,
const SbBool    neednormals,
SbBool &    normalcacheused
[protected]
 

Convenience method that will fetch data needed for rendering or generating primitives. Takes care of normal cache.
