NAMESoTransparencyType − The SoTransparencyType class is a node for setting the transparency type for shapes.

Detailed DescriptionThe SoTransparencyType class is a node for setting the transparency type for shapes. In earlier versions of Coin/Open Inventor it was only possible to set the transparency mode globally for an entire scene graph, which could be inconvenient if different transparency types was wanted for different shapes. Here is a screenshot of the different transparency modes used in a single scene.
Rendering of Different Transparency Modes Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

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