In addition to being very knowledgable, Yann is very patient...

The developer pages at both ATI and nVidia''s sites are good places to start. Take a look there. Also, my book listed below might be helpful, although your GF2 will not do pixel shading. This is not to say that you can''t do other texture operations, but the GF2 doesn''t know how to execute a real pixel shader.

What are you actually trying to do? Perhaps you don''t need a pixel shader...

Yeah, you are lucky that you have had as many helpful replies as you have gotten with your attitude. Yann L happens to be one of best graphics programmers I know of, so I wouldn''t try and prove him or certain other people in this forum wrong.

Well, I wish you good luck. Especially with that attitude.

Well, I wish you good luck. Especially with that serious disservice of a lie you told and continue to distort.

Perhaps now you just lost a potential buyer of your book!

Perhaps now you just lost your whole GDNet reputation!

Look, I know there''s a search engine called Google, and I also know how to use it. Ya think I would have done that by now? But nope, neither you can find something useful with it!

Did you even read the link I provided? Have you bothered to look further at any of the sites listed already?

I''ll be nice, and i''ll provide you one more spoon-fed link on combiners. But only because I''m waiting for a compile to finish and fed up staring at my own code

Like I said... the original responder to your post... check out the nvidia and ati developement sites. They are full of useful information about programming their products. I was just saying that they ALSO HAVE Cg, it doesn''t mean it is limited to Cg, you can also find information on the low level asm coding for the vertex shading programs of the gf2 (although, i beleive this runs in software). I pointed you in the direction for the information you requested, and in a polite manner, please go read their dev pages, and then come back and ask about information that you still need, or can''t find.

That''s okay, although I''m not sure why you didn''t like my response. I am honestly not answering to sell books, but you asked for low level shaders and the book happens to be chock full of ''em. If you would rather not buy it, I mentioned two other very good resources. You could also look at ShaderX, and several other very good books. "Real Time Rendering" by Haines and Akenine-Moller is a nice all around book.

When you feel less vitriolic, please let us know what you want to do. You might not need pixel shaders. Also, software vertex shaders might work nicely for you.
