Chapter 7 G 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. GL_hp_TEXTURING_LIGHTING 171
