G glGet params returns four values: the x and y window coordinates of the scissor box, followed by its width and height. Initially the x and y window coordinates are both 0 and the width and height are set to the size of the window. See glScissor. GL_SCISSOR_TEST params returns a single boolean value indicating whether scissoring is enabled. The initial value is GL_FALSE. See glScissor. GL_SHADE_MODEL params returns one value, a symbolic constant indicating whether the shading mode is flat or smooth. The initial value is GL_SMOOTH. See glShadeModel. GL_STENCIL_BITS params returns one value, the number of bitplanes in the stencil buffer. GL_STENCIL_CLEAR_VALUE params returns one value, the index to which the stencil bitplanes are cleared. The initial value is 0. See glClearStencil. GL_STENCIL_FAIL params returns one value, a symbolic constant indicating what action is taken when the stencil test fails. The initial value is GL_KEEP. See glStencilOp. GL_STENCIL_FUNC params returns one value, a symbolic constant indicating what function is used to compare the stencil reference value with the stencil buffer value. The initial value is GL_ALWAYS. See glStencilFunc. GL_STENCIL_PASS_DEPTH_FAIL params returns one value, a symbolic constant indicating what action is taken when the stencil test passes, but the depth test fails. The initial value is GL_KEEP. See glStencilOp. GL_STENCIL_PASS_DEPTH_PASS params returns one value, a symbolic constant indicating what action is taken when the stencil test passes and the depth test passes. The initial value is GL_KEEP. See glStencilOp. GL_STENCIL_REF params returns one value, the reference value that is compared with the contents of the stencil buffer. The initial value is 0. See glStencilFunc. GL_STENCIL_TEST params returns a single boolean value indicating whether stencil testing of fragments is enabled. The initial value is GL_FALSE. See glStencilFunc and glStencilOp. GL_STENCIL_VALUE_MASK params returns one value, the mask that is used to mask both the stencil reference value and the stencil buffer value before they are compared. The initial value is all 1s. See glStencilFunc. GL_STENCIL_WRITEMASK Chapter 7 181
