The initial value for each _param1 is _const(DONT_CARE). -_param2 can be one of the following: -.TP 20 -_const(FASTEST) -The most efficient option should be chosen. -.TP -_const(NICEST) -The most correct, -or highest quality, -option should be chosen. -.TP -_const(DONT_CARE) -No preference. -.P -Though the implementation aspects that can be hinted are well defined, -the interpretation of the hints depends on the implementation. -The hint aspects that can be specified with _param1, -along with suggested semantics, -are as follows: -.TP 20 -_const(FOG_HINT) -Indicates the accuracy of fog calculation. -If per-pixel fog calculation is not efficiently supported -by the GL implementation, -hinting _const(DONT_CARE) or _const(FASTEST) can result in per-vertex -calculation of fog effects. -.TP -_const(LINE_SMOOTH_HINT) -Indicates the sampling quality of antialiased lines. -If a larger filter function is applied, hinting _const(NICEST) can -result in more pixel fragments being generated during rasterization, -.TP -_const(PERSPECTIVE_CORRECTION_HINT) -Indicates the quality of color and texture coordinate interpolation. -If perspective-corrected parameter interpolation is not efficiently supported -by the GL implementation, -hinting _const(DONT_CARE) or _const(FASTEST) can result in simple linear -interpolation of colors and/or texture coordinates. -.TP -_const(POINT_SMOOTH_HINT) -Indicates the sampling quality of antialiased points. -If a larger filter function is applied, hinting _const(NICEST) can -result in more pixel fragments being generated during rasterization, -.TP -_const(POLYGON_SMOOTH_HINT) -Indicates the sampling quality of antialiased polygons. -Hinting _const(NICEST) can result in more pixel fragments being generated -during rasterization, -if a larger filter function is applied. -.SH NOTES -The interpretation of hints depends on the implementation. -Some implementations ignore _cmnd(Hint) settings. -.SH ERRORS -_const(INVALID_ENUM) is generated if either _param1 or _param2 is not -an accepted value. -.P -_const(INVALID_OPERATION) is generated if _cmnd -is executed between the execution of _cmnd(Begin) -and the corresponding execution of _cmnd(End). |
