glGet
params returns a single boolean value indicating whether edge clamping is enabled. The
initial value is GL_FALSE. See glTexImage3DEXT.
GL_FOG
params returns a single boolean value indicating whether fogging is enabled. The initial
value is GL_FALSE. See glFog.
GL_FOG_COLOR
params returns four values: the red, green, blue and alpha components of the fog color.
Integer values, if requested, are linearly mapped from the internal floating-point
representation such that 1.0 returns the most positive representable integer value, and -
1.0 returns the most negative representable integer value. The initial value is (0, 0, 0, 0).
See glFog.
GL_FOG_DENSITY
params returns one value, the fog density parameter. The initial value is 1. See glFog.
GL_FOG_END
params returns one value, the end factor for the linear fog equation. The initial value is
1. See glFog.
GL_FOG_HINT
params returns one value, a symbolic constant indicating the mode of the fog hint. The
initial value is GL_DONT_CARE. See glHint.
GL_FOG_INDEX
params returns one value, the fog color index. The initial value is 0. See glFog.
GL_FOG_MODE
params returns one value, a symbolic constant indicating which fog equation is selected.
The initial value is GL_EXP. See glFog.
GL_FOG_START
params returns one value, the start factor for the linear fog equation. The initial value is
0. See glFog.
GL_FRONT_FACE
params returns one value, a symbolic constant indicating whether clockwise or
counterclockwise polygon winding is treated as front-facing. The initial value is
GL_CCW. See glFrontFace.
GL_GREEN_BIAS
params returns one value, the green bias factor used during pixel transfers. The initial
value is 0.
GL_GREEN_BITS
params returns one value, the number of green bitplanes in each color buffer.
GL_GREEN_SCALE
params returns one value, the green scale factor used during pixel transfers. The initial
value is 1. See glPixelTransfer.
