The SoColorIndex class is used to specify color indices for subsequent shapes.
This node should only be used in OpenGL color-index mode, and only when the current light model is set to SoLightModel::BASE_COLOR.
OpenGL colorindex mode is where the colors for individual pixels are fetched from a color lookup table ("CLUT"). The usual thing to do is to set up a canvas in RGBA truecolor mode.
One common use for colorindex mode OpenGL canvases is to use one in the overlay planes (which are usually limited to only 2 or 4 available colors), if supported by the OpenGL hardware and / or driver.
FILE FORMAT/DEFAULTS:
SoColorIndex::SoColorIndex | ( | void | ) |
Constructor.
|
protectedvirtual |
Destructor.
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.
Implements SoBase.

protectedvirtual |
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL
.
Reimplemented from SoFieldContainer.
|
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.
SoMFInt32 SoColorIndex::index |
Color indices which can be used by shapes.
