glGet
params returns a single boolean value indicating whether polygon offset is enabled for
polygons in line mode. The initial value is GL_FALSE. See glPolygonOffset.
GL_POLYGON_OFFSET_POINT
params returns a single boolean value indicating whether polygon offset is enabled for
polygons in point mode. The initial value is GL_FALSE. See glPolygonOffset.
GL_POLYGON_SMOOTH
params returns a single boolean value indicating whether anti-aliasing of polygons is
enabled. The initial value is GL_FALSE. See glPolygonMode.
GL_POLYGON_SMOOTH_HINT
params returns one value, a symbolic constant indicating the mode of the polygon
anti-aliasing hint. The initial value is GL_DONT_CARE. See glHint.
GL_POLYGON_STIPPLE
params returns a single boolean value indicating whether polygon stippling is enabled.
The initial value is GL_FALSE. See glPolygonStipple.
GL_PROJECTION_MATRIX
params returns sixteen values: the projection matrix on the top of the projection matrix
stack. Initially this matrix is the identity matrix. See glPushMatrix.
GL_PROJECTION_STACK_DEPTH
params returns one value, the number of matrices on the projection matrix stack. The
initial value is 1. See glPushMatrix.
GL_READ_BUFFER
params returns one value, a symbolic constant indicating which color buffer is selected
for reading. The initial value is GL_BACK if there is a back buffer, otherwise it is
GL_FRONT. See glReadPixels and glAccum.
GL_RED_BIAS
params returns one value, the red bias factor used during pixel transfers. The initial
value is 0.
GL_RED_BITS
params returns one value, the number of red bitplanes in each color buffer.
GL_RED_SCALE
params returns one value, the red scale factor used during pixel transfers. The initial
value is 1. See glPixelTransfer.
GL_RENDER_MODE
params returns one value, a symbolic constant indicating whether the GL is in render,
select, or feedback mode. The initial value is GL_RENDER. See glRenderMode.
GL_RGBA_MODE
params returns a single boolean value indicating whether the GL is in RGBA mode
(true) or color index mode (false). See glColor.
