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 2m−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.
