func Specifies the test function. Eight tokens are valid: GL_NEVER, GL_LESS, GL_LEQUAL, GL_GREATER, GL_GEQUAL, GL_EQUAL, GL_NOTEQUAL, and GL_ALWAYS. The initial value is GL_ALWAYS. ref Specifies the reference value for the stencil test. ref is clamped n to the range [0,2 -1], where n is the number of bitplanes in the stencil buffer. The initial value is 0. mask Specifies a mask that is ANDed with both the reference value and the stored stencil value when the test is done. The initial value is al... |

mask Specifies a bit mask to enable and disable writing of individual bits in the stencil planes. Initially, the mask is all 1's. |

OpenGL/glstencilop(3) -- set stencil test actions
|
|
fail Specifies the action to take when the stencil test fails. Six symbolic constants are accepted: GL_KEEP, GL_ZERO, GL_REPLACE, GL_INCR, GL_DECR, and GL_INVERT. The initial value is GL_KEEP. zfail Specifies the stencil action when the stencil test passes, but the depth test fails. zfail accepts the same symbolic constants as fail. The initial value is GL_KEEP. zpass Specifies the stencil action when both the stencil test and the depth test pass, or when the stencil test passes and either there... |

OpenGL/gltagsamplebuffersgix(3) -- mark all samples of a multisample buffer
|
|
When using a multisample buffer on some systems (see Machine Dependencies below), glTagSampleBufferSGIX can be used with some restrictions as a faster alternative to clearing the depth buffer using glClear. On these system, each sample in the multisample buffer carries a tag that can be either set or cleared. glTagSampleBufferSGIX sets the tags of all the samples. When a tag of a sample is set, a depth test against that sample always succeeds. Note, however, that the stencil test (if enabled) st... |

OpenGL/gltexcoord(3) -- set the current texture coordinates
|
|
s, t, r, q Specify s, t, r, and q texture coordinates. Not all parameters are present in all forms of the command. |

|
|
size Specifies the number of coordinates per array element. Must be 1, 2, 3 or 4. The initial value is 4. type Specifies the data type of each texture coordinate. Symbolic constants GL_SHORT, GL_INT, GL_FLOAT, or GL_DOUBLE are accepted. The initial value is GL_FLOAT. stride Specifies the byte offset between consecutive array elements. If stride is 0, the array elements are understood to be tightly packed. The initial value is 0. pointer Specifies a pointer to the first coordinate of the first el... |
