The SoGLColorIndexElement class sets the current OpenGL color.
This element is only used when the OpenGL canvas is in color index mode, i.e. 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 true color mode.
One common use for color index 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.

protectedvirtual |
Destructor.
|
static |
This static method returns the SoType object associated with objects of this class.
|
static |
This static method returns the state stack index for the class.
|
static |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Creates a new instance of the class type corresponding to the SoType object.
|
static |
Initialize relevant common data for all instances, like the type system.
Returns TRUE
if the current GL context is in color index mode.
|
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.
|
static |
Sets current color indices.
|
static |
Returns the current element.
int32_t SoGLColorIndexElement::getNum | ( | void | ) | const |
Returns number of color indices in element.
int32_t SoGLColorIndexElement::get | ( | const int | index | ) | const |
Returns the index'th color index in element.
|
static |
Returns the default color index in element.
