NAME

glClearIndex - specify the clear value for the color index buffers

C SPECIFICATION

void glClearIndex( GLfloat c )

PARAMETERS

c: Specifies the index used when the color index buffers are cleared. The initial value is 0.

DESCRIPTION

glClearIndex specifies the index used by glClear to clear the color index buffers. c is not clamped. Rather, c is converted to a fixed-point value with unspecified precision to the right of the binary point. The integer part of this value is then masked with

2^{m} - 1

, where

m

is the number of bits in a color index stored in the frame buffer.

ERRORS

GL_INVALID_OPERATION is generated if glClearIndex is executed between the execution of glBegin and the corresponding execution of glEnd.
