glGet
params returns one value, the maximum supported depth of the texture matrix stack.
The value must be at least 2. See glPushMatrix.
GL_MAX_VIEWPORT_DIMS
params returns two values: the maximum supported width and height of the viewport.
These must be at least as large as the visible dimensions of the display being rendered
to. See glViewport.
GL_MODELVIEW_MATRIX
params returns sixteen values: the modelview matrix on the top of the modelview matrix
stack. Initially this matrix is the identity matrix. See glPushMatrix.
GL_MODELVIEW_STACK_DEPTH
params returns one value, the number of matrices on the modelview matrix stack. The
initial value is 1. See glPushMatrix.
GL_NAME_STACK_DEPTH
params returns one value, the number of names on the selection name stack. The initial
value is 0. See glPushName.
GL_NORMAL_ARRAY
params returns a single boolean value, indicating whether the normal array is enabled.
The initial value is GL_FALSE. See glNormalPointer.
GL_NORMAL_ARRAY_STRIDE
params returns one value, the byte offset between consecutive normals in the normal
array. The initial value is 0. See glNormalPointer.
GL_NORMAL_ARRAY_TYPE
params returns one value, the data type of each coordinate in the normal array. The
initial value is GL_FLOAT. See glNormalPointer.
GL_NORMALIZE
params returns a single boolean value indicating whether normals are automatically
scaled to unit length after they have been transformed to eye coordinates. The initial
value is GL_FALSE. See glNormal.
GL_OCCLUSION_TEST_hp
params returns a single boolean value indicating whether HP's occlusion-testing
extension is currently activated. See glEnable.
GL_OCCLUSION_TEST_RESULT_hp
params returns a single boolean value indicating whether the previously-rendered
geometry was entirely occluded. A side-effect of getting this value is that the flag is
cleared (in preparation for the next occlusion test). See glEnable.
GL_PACK_ALIGNMENT
params returns one value, the byte alignment used for writing pixel data to memory. The
initial value is 4. See glPixelStore.
