I agree that we should support more data formats in the framebuffer, but the shader engine need only understand 32-bit float and 32-bit int. Everything else would be managed as a conversion during I/O with the memory system. -- Timothy Normand Miller http://www.cse.ohio-state.edu/~millerti Open Graphics Project _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
