NAME
glClearIndex - specify the clear value for the color index buffersC SPECIFICATION
void glClearIndex( GLfloat c )delim $$
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 $2 sup m^-^1$, 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.ASSOCIATED GETS
glGet with argument GL_INDEX_CLEAR_VALUEglGet with argument GL_INDEX_BITS
