The initial value is 0. -_phead(_param2) -Is multiplied by an implementation-specific value to -create a constant depth offset. The initial value is 0. -.SH DESCRIPTION -When _const(POLYGON_OFFSET_FILL), _const(POLYGON_OFFSET_LINE), or -_const(POLYGON_OFFSET_POINT) is enabled, each -fragment's \f2depth\fP value will be offset after it is interpolated -from the \f2depth\fP values of the appropriate vertices. -The value of the offset is $_eqnparam1 ~*~ DZ ~~+~~ r ~*~ _eqnparam2$, -where $DZ~$ is a measurement of the change in depth relative to the screen -area of the polygon, and $r$ is the smallest value that is guaranteed to -produce a resolvable offset for a given implementation. -The offset is added before the depth test is performed and before -the value is written into the depth buffer. -.P -_cmnd is useful for rendering hidden-line images, for applying decals -to surfaces, and for rendering solids with highlighted edges. -.SH NOTES -_cmnd is available only if the GL version is 1.1 or greater. -.P -_cmnd has no effect on depth coordinates placed in the -feedback buffer. -.P -_cmnd has no effect on selection. -.SH ERRORS -_const(INVALID_OPERATION) is generated if _cmnd is executed -between the execution of _cmnd(Begin) and the corresponding -execution of _cmnd(End). -.bp -.SH ASSOCIATED GETS -_cmnd(IsEnabled) with argument -_const(POLYGON_OFFSET_FILL), -_const(POLYGON_OFFSET_LINE), -or _const(POLYGON_OFFSET_POINT). -.P -_cmnd(Get) with argument _const(POLYGON_OFFSET_FACTOR) or -_const(POLYGON_OFFSET_UNITS). -.SH SEE ALSO -_cmnd(DepthFunc), -_cmnd(Enable), -_cmnd(Get), -_cmnd(IsEnabled) |
