What do pixel shaders actually do?

Simply put you have vertex and pixel shaders.

[edit] Damn Roge whipped me to it! :-)[/edit]

both are "programs" which are executed for every vertex or pixel fragment that is processed by the card.

for instance your vertex shade would take in the vertex x,y,z colour etc of the vertex. And a transformation matrix. The code in the vertex shader would then apply the matrix to the vert, and write out the result to specified registers/vars.

Similar thing for pixel shaders, but you get texels from textures and so on instead of x,y,z... values.

This gives programmers freedom (within reason) to do stuff as they want compared to the old fixed function type pipelines.

I hope that made sense, if so Yay! for me! :-D

@Rogue

  Just like to say I'm most impressed with your work. They must have you tied up in that basement, giving you the occasional whipping to encourage you to produce so much!    (unless of course you take that to be a perk of the job hehe :-D )

As for the 3D interface, I'm assuming in the future you are looking to support the T&L stuff. The speed difference is quite amazing when here at work you force the T&L into software vertex processing as apposed to HW.

Anyhow keep up the good work....

...oh and when will it be ready! (*snigger* :-P )
