G
glGet
params returns a single boolean value indicating whether texture lighting is enabled.
The initial value is GL_FALSE. See glTexImage3DEXT.
GL_INDEX_ARRAY
params returns a single boolean value indicating whether the color index array is
enabled. The initial value is GL_FALSE. See glIndexPointer.
GL_INDEX_ARRAY_STRIDE
params returns one value, the byte offset between consecutive color indexes in the color
index array. The initial value is 0. See glIndexPointer.
GL_INDEX_ARRAY_TYPE
params returns one value, the data type of indexes in the color index array. The initial
value is GL_FLOAT. See glIndexPointer.
GL_INDEX_BITS
params returns one value, the number of bitplanes in each color index buffer.
GL_INDEX_CLEAR_VALUE
params returns one value, the color index used to clear the color index buffers. The
initial value is 0. See glClearIndex.
GL_INDEX_LOGIC_OP
params returns a single boolean value indicating whether a fragment's index values are
merged into the frame buffer using a logical operation. The initial value is GL_FALSE.
See glLogicOp.
GL_INDEX_MODE
params returns a single boolean value indicating whether the GL is in color index mode
(GL_TRUE) or RGBA mode (GL_FALSE).
GL_INDEX_OFFSET
params returns one value, the offset added to color and stencil indices during pixel
transfers. The initial value is 0. See glPixelTransfer.
GL_INDEX_SHIFT
params returns one value, the amount that color and stencil indices are shifted during
pixel transfers. The initial value is 0. See glPixelTransfer.
GL_INDEX_WRITEMASK
params returns one value, a mask indicating which bitplanes of each color index buffer
can be written. The initial value is all 1s. See glIndexMask. GL_LIGHTi params returns
a single boolean value indicating whether the specified light is enabled. The initial value
is GL_FALSE. See glLight and glLightModel.
GL_LIGHTING
params returns a single boolean value indicating whether lighting is enabled. The initial
value is GL_FALSE. See glLightModel.
