NAME

       SoColorIndex -

       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.

SYNOPSIS

       #include <Inventor/nodes/SoColorIndex.h>

Detailed Description

       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:

           ColorIndex {
               index 1
           }

Member Function Documentation

   void SoColorIndex::initClass (void) [static] Sets up initialization for
       data common to all instances of this class, like submitting necessary
       information to the Coin type system.
       Reimplemented from SoNode.

   void SoColorIndex::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

   SoMFInt32 SoColorIndex::index Color indices which can be used by shapes.
