with if it works nicely, even with shader model 1.1.
what does this get translated into?
does this have any disadvantages?
edit: weird! how can so many ifs work with 1.1 (which just supported 8 assembler instructions if i remember correctly)? could it be that ps_1_1 gets ignored and the shader model of the gpu always gets used? which would be really stupid since my card supports 4.0 and i have to develop for 1.1. is there some way to force 1.1?
The problem there is interpolation, but I doubt that you will stay wthin the limits otherwize.
the hard borders don't look as well as i had imagined. so interpolation probably would be better anyway.
