Member Function Documentation

  SoType SoVRMLVertexLine::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 from SoVRMLGeometry.

Reimplemented in SoVRMLIndexedLineSet, and SoVRMLIndexedLine.

  const SoFieldData * SoVRMLVertexLine::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 SoVRMLGeometry.

Reimplemented in SoVRMLIndexedLineSet, and SoVRMLIndexedLine.

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

Reimplemented from SoNode.

  void SoVRMLVertexLine::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 SoVRMLIndexedLineSet.

  void SoVRMLVertexLine::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 SoVRMLIndexedLineSet.

  void SoVRMLVertexLine::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 SoVRMLVertexLine::pick (SoPickAction * action) [virtual]
Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

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

Reimplemented from SoVRMLGeometry.

Reimplemented in SoVRMLIndexedLine, and SoVRMLIndexedLineSet.

  SbBool SoVRMLVertexLine::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.

Member Data Documentation

  SoSFNode SoVRMLVertexLine::coord
Should contain an SoVRMLCoordinate node.

  SoSFNode SoVRMLVertexLine::color
Can contain an SoVRMLColor node if multiple colors are wanted.

  SoSFBool SoVRMLVertexLine::colorPerVertex
When TRUE, colors will be bound per vertex, otherwise per line. Default value is TRUE.
