We had some discussions early on in the project, and people made some solid arguments for cases where fixed just would not do. Perspective correction is one of them. OGA is virtually float all the way through, but there are points in the pipeline where we no longer need the precision and convert to fixed. The head of the pipeline, however, is all float (except target screen coordinates). _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
