The SoAnnotation node draws all its child geometry on top of other geometry.
This group-type node uses delayed rendering in combination with Z-buffer disabling to let its children transparently render their geometry on top of the other geometry in the scene.
Since the Z-buffer needs to be disabled, the childrens' geometry will not be rendered back-to-front sorted, but rather in the order they are present in the scenegraph.

Constructor.
|
protectedvirtual |
Destructor.
|
static |
This static method returns the SoType object associated with objects of this class.
Reimplemented from SoSeparator.
|
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:
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.

staticprotected |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Reimplemented from SoSeparator.
|
protectedvirtual |
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL
.
Reimplemented from SoSeparator.
|
static |
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
Reimplemented from SoSeparator.
|

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 SoSeparator.

SGI Open Inventor v2.1 obsoleted support for SoGLRenderAction::addMethod(). Instead, GLRender() might be called directly, and to optimize traversal, the SoSeparator node calls GLRenderBelowPath whenever the path code is BELOW_PATH or NO_PATH (path code is guaranteed not to change). To be compatible with SGI's Inventor (and thereby also TGS') we have chosen to follow their implementation in this respect.
SoSeparator::GLRenderBelowPath() do not traverse its children using SoChildList::traverse(), but calls GLRenderBelowPath() directly for all its children.
Reimplemented from SoSeparator.

Implements the SoAction::OFF_PATH traversal method for the rendering action.
