projection shader - 03/14/05 01:14
hello everyone,
i wanna ask if someone can help me update the projection shader to DX9.
i wanted to do myself and went through the manual with all lines that are in there (i learned from it, but obviously not enough :P).
i came as far as to update 4 lines to DX9 code (which are stated in the code as a comment, you should see them ^_^ ).
anyone know what to update more on this code to get it to work, or does someone has me a HLSL code for this ??
hope someone can help.
Code:
with kind regards and TIA,
