With vertex/pixel shaders being the next big thing is anyone else trying to figure out how to get started with them? I am curious what will be THE TOOL to make shaders with. Right now there is CG and some other programs but with my geforce2 is dose not seem like I can get involved with shaders. I am still not clear about shaders. As far as adding them to a mesh is it ok if I think of shaders like I do textures? I mean will there be a program that is easy to use to create shaders in and let me just plug it into my mesh on the programming end? (generate the CG script for me) If anyone knows the best way to get started with all this let me know.

I''m not yet started with shaders. I now my GL quit well but I thought that DX has some better shader options so I first started with learning DX and then I want to continue with Shaders.

If you''re using DX you could have a look at the sdk from M$.

Also the tutorials on the FP of gamedev and the info on the developer sites of ATI and Nvidia should help to get you started

I have looked at them some but the main problem is getting anything to run with a geforce 2. Is it possible to learn about shaders without a geforce3 or above? I would like to hear from anybody with a geforce2 who is working with shaders.

To start out I was hoping to find a program that helps generate the CG code for you rather than me write it since I don''t seem to understand linear algebra

I am currently using OpenGL as well, but would like to work with pixel shaders on both OGL and DX. Do either or both of these have software implementations that will run on a geforce2(go)? Yes, I know: speed. For debugging purposes only.

Thanks,

save here. I have the geforce2 and I do not care if it is 1 frame a second. I would like to be able
to play with pixel shaders now.

I do have a program that uses vertex shaders with my geforce2 I can send to you and you can try to compile

vertex shaders should run decently on a GF2, but pixel shaders are a different story. You might want to experiment with them and upgrade to GF3 class hardware when the price drops further.

ok but CAN I experiment them?

I loaded up the CG toolkit and some effect seemed blurred out.. I was assuming it was since I had a geforce2

Or should always the pixel shader programs run on geforce2 (yes I know maybe 100x slower )_

You can experiment with them, although it''s possible that some apps might not gracefully fall down to a ref device.

Just to give you some context, I wrote "Real time rendering tricks and techniques" on a GF2Go laptop. I also used a GF3, but I was able to proof the apps on the laptop without any problems.
