Detailed Description

ShadowCulling {
    mode AS_IS_CULLING
}

Member Enumeration Documentation

  enum SoShadowCulling::Mode
Enumerates the available culling modes.

Enumerator

AS_IS_CULLING
    Use the culling specified in the scene graph.

NO_CULLING
    Render both backfacing and frontfacting triangles into the shadow map.

Constructor & Destructor Documentation

  SoShadowCulling::SoShadowCulling (void)
Constructor.

  SoShadowCulling::~SoShadowCulling () [protected], [virtual]
Destructor.

Member Function Documentation

  SoType SoShadowCulling::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.

Implements SoBase.

  const SoFieldData * SoShadowCulling::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 SoFieldContainer.

  void SoShadowCulling::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 SoNode.

Member Data Documentation

  SoSFEnum SoShadowCulling::mode
Sets the culling mode. Default is AS_IS_CULLING.
