glClearIndex
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
default value is zero
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 called
between a call to glBegin and the
corresponding call to glEnd.
