NAME¶
SoGLColorIndexElement - The SoGLColorIndexElement class sets the current OpenGL color. This element is only used when the OpenGL canvas is in colorindex mode, ie where 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.SYNOPSIS¶

The destructor.Member Function Documentation¶
SoType SoGLColorIndexElement::getClassTypeId (void) [static]¶
This static method returns the class type. Reimplemented from SoReplacedElement.int SoGLColorIndexElement::getClassStackIndex (void) [static]¶
This static method returns the state stack index for the class. Reimplemented from SoReplacedElement.void * SoGLColorIndexElement::createInstance (void) [static]¶
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.void SoGLColorIndexElement::initClass (void) [static]¶
Initialize relevant common data for all instances, like the type system. Reimplemented from SoReplacedElement.SbBool SoGLColorIndexElement::isColorIndexMode (SoState *state) [static]¶
Returns TRUE if the current GL context is in color index mode.void SoGLColorIndexElement::init (SoState *state) [virtual]¶
This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects. Reimplemented from SoReplacedElement.void SoGLColorIndexElement::set (SoState *conststate, SoNode *constnode, const int32_tnumindices, const int32_t *constindices) [static]¶
Sets current color indices.const SoGLColorIndexElement * SoGLColorIndexElement::getInstance ( SoState *state) [static]¶
Returns the current element.int32_t SoGLColorIndexElement::getNum (void) const¶
Returns number of color indices in element.Author¶
