Polygon stippling is initially -disabled. If it's enabled, -a rasterized polygon fragment with window coordinates $x sub w$ and $y sub w$ -is sent to the next stage of the GL if and only if the -($x sub w~roman mod~32$)th bit in the ($y sub w~roman mod~32$)th row -of the stipple pattern is 1 (one). -When polygon stippling is disabled, it is as if the stipple pattern -consists of all 1's. -.SH ERRORS -_const(INVALID_OPERATION) is generated if _cmnd -is executed between the execution of _cmnd(Begin) -and the corresponding execution of _cmnd(End). -.SH ASSOCIATED GETS -_cmnd(GetPolygonStipple) -.br -_cmnd(IsEnabled) with argument _const(POLYGON_STIPPLE) -.SH SEE ALSO -_cmnd(DrawPixels), -_cmnd(LineStipple), -_cmnd(PixelStore), -_cmnd(PixelTransfer) |
