G glGet 166 GL_ACCUM_CLEAR_VALUE params returns four values: the red, green, blue, and alpha values used to clear the accumulation buffer. 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 glClearAccum. GL_ACCUM_GREEN_BITS params returns one value, the number of green bitplanes in the accumulation buffer. GL_ACCUM_RED_BITS params returns one value, the number of red bitplanes in the accumulation buffer. GL_ALPHA_BIAS params returns one value, the alpha bias factor used during pixel transfers. The initial value is 0.See glPixelTransfer. GL_ALPHA_BITS params returns one value, the number of alpha bitplanes in each color buffer. GL_ALPHA_SCALE params returns one value, the alpha scale factor used during pixel transfers. The initial value is 1. See glPixelTransfer. GL_ALPHA_TEST params returns a single boolean value indicating whether alpha testing of fragments is enabled. The initial value is GL_FALSE. See glAlphaFunc. GL_ALPHA_TEST_FUNC params returns one value, the symbolic name of the alpha test function. The initial value is GL_ALWAYS. See glAlphaFunc. GL_ALPHA_TEST_REF params returns one value, the reference value for the alpha test. The initial value is 0. See glAlphaFunc. An integer value, if requested, is 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. GL_ATTRIB_STACK_DEPTH params returns one value, the depth of the attribute stack. If the stack is empty, 0 is returned. The initial value is 0. See glPushAttrib. GL_AUTO_NORMAL params returns a single boolean value indicating whether 2D map evaluation automatically generates surface normals. The initial value is GL_FALSE. See glMap2. GL_AUX_BUFFERS params returns one value, the number of auxiliary color buffers. The initial value is 0. GL_BLEND params returns a single boolean value indicating whether blending is enabled. The initial value is GL_FALSE. See glBlendFunc. Chapter 7
