Member Function Documentation

   void SoVRMLVertexPoint::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 SoVRMLGeometry.

       Reimplemented in SoVRMLPointSet.

   void SoVRMLVertexPoint::doAction (SoAction * action) [virtual] This
       function performs the typical operation of a node for any action.
       Reimplemented from SoNode.

   void SoVRMLVertexPoint::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 SoShape.

       Reimplemented in SoVRMLPointSet.

   void SoVRMLVertexPoint::getBoundingBox (SoGetBoundingBoxAction * action)
       [virtual] Action method for the SoGetBoundingBoxAction.
       Calculates bounding box and center coordinates for node and modifies
       the values of the action to encompass the bounding box for this node
       and to shift the center point for the scene more towards the one for
       this node.

       Nodes influencing how geometry nodes calculates their bounding box also
       overrides this method to change the relevant state variables.

       Reimplemented from SoShape.

       Reimplemented in SoVRMLPointSet.

   void SoVRMLVertexPoint::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 SoShape.

   void SoVRMLVertexPoint::pick (SoPickAction * action) [virtual] Action
       method for SoPickAction.
       Does common processing for SoPickAction action instances.

       Reimplemented from SoNode.

   void SoVRMLVertexPoint::getPrimitiveCount (SoGetPrimitiveCountAction *
       action) [virtual] Action method for the SoGetPrimitiveCountAction.
       Calculates the number of triangle, line segment and point primitives
       for the node and adds these to the counters of the action.

       Nodes influencing how geometry nodes calculates their primitive count
       also overrides this method to change the relevant state variables.

       Reimplemented from SoShape.

   void SoVRMLVertexPoint::notify (SoNotList * l) [virtual] Notifies all
       auditors for this instance when changes are made.
       Reimplemented from SoVRMLGeometry.

   SbBool SoVRMLVertexPoint::shouldGLRender (SoGLRenderAction * action)
       [protected, virtual] This API member is considered internal to the
       library, as it is not likely to be of interest to the application
       programmer.
       Reimplemented from SoVRMLGeometry.

   void SoVRMLVertexPoint::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.

Member Data Documentation

   SoSFNode SoVRMLVertexPoint::coord Should contain an SoVRMLCoordinate node.
   SoSFNode SoVRMLVertexPoint::color Can contain an SoVRMLColor node when
       color per point is needed.
