Member Function Documentation

SoType SoVRMLIndexedShape::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoVRMLVertexShape.

Reimplemented in SoVRMLIndexedFaceSet.

SoType SoVRMLIndexedShape::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 in SoVRMLIndexedFaceSet.

const SoFieldData ** SoVRMLIndexedShape::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 SoVRMLVertexShape.

Reimplemented in SoVRMLIndexedFaceSet.

const SoFieldData * SoVRMLIndexedShape::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 SoVRMLVertexShape.

Reimplemented in SoVRMLIndexedFaceSet.

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.

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 SbBoolneednormals, SbBool &normalcacheused) [protected]

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