glGet
params returns a single boolean value indicating whether a fragment's RGBA color
values are merged into the frame buffer using a logical operation. The initial value is
GL_FALSE. See glLogicOp.
GL_COLOR_MATERIAL
params returns a single boolean value indicating whether one or more material
parameters are tracking the current color. The initial value is GL_FALSE. See
glColorMaterial.
GL_COLOR_MATERIAL_FACE
params returns one value, a symbolic constant indicating which materials have a
parameter that is tracking the current color. The initial value is
GL_FRONT_AND_BACK. See glColorMaterial.
GL_COLOR_MATERIAL_PARAMETER
params returns one value, a symbolic constant indicating which material parameters
are tracking the current color. The initial value is GL_AMBIENT_AND_DIFFUSE. See
glColorMaterial.
GL_COLOR_WRITEMASK
params returns four boolean values: the red, green, blue, and alpha write enables for the
color buffers. The initial value is (GL_TRUE, GL_TRUE, GL_TRUE, GL_TRUE). See
glColorMask.
GL_CULL_FACE
params returns a single boolean value indicating whether polygon culling is enabled.
The initial value is GL_FALSE. See glCullFace.
GL_CULL_FACE_MODE
params returns one value, a symbolic constant indicating which polygon faces are to be
culled. The initial value is GL_BACK. See glCullFace.
GL_CURRENT_COLOR
params returns four values: the red, green, blue, and alpha values of the current 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. See glColor. The initial value
is (1, 1, 1, 1).
GL_CURRENT_INDEX
params returns one value, the current color index. The initial value is 1. See glIndex.
GL_CURRENT_NORMAL
params returns three values: the x, y, and z values of the current normal. 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, 1). See glNormal.
