Hi, I would go with drawing the polygon over the screen Its fast, and you could make it any color you wanted to.
Tell it to Carmak! :twisted:
Do you know what Quake3 engine uses special gamme correction table for "overbright" lighting? And Gamme correction is indeed is higher precision.

Corrections? Clarifications? Miscellaneous threats? Post them here, please.
Some drivers (incorrectly) return only BYTE filled precision - i.e. only lower byte is meaningfull with higher set to zero - when called by GetGammeRamp, but assume what you pass 16it - WORD filled gamma ramp table.
