Well, I don't really know. I am actually working on polygon Library, maybe I will try to do a demo after  :P

some test with the pxl and the geometry shader.
The first screen, I only pass one primitive (only one quad) as argument, the shader create a new piece of geometry from the one already there.


+-20fps

this is th pxl shader test, a full cube (6 quad) and in each line a pxl who get randomly off.



+-4 fps

all is at 6MHz

If you'd deform the reflection by a sine or such, you could make a water shader of this.

Yes guess so. A shadow shader would not so hard to do too, though.
Anyway, I started play with the pixel shader in this area (distorsion), and here what I've got so far (yay pseudo vector slime !  :D )

Wow I love it! With a very large shape, does it slow things down a lot?

there is very few speed loss, and even if the speed decrease more when a big shape is drawn, it's more because of the triangle routine than the pxlshader actually  :P

some progress in the lib  :D, however I can't upload anything due to how crappy the connexion is  <_<

anyway, I sightly modified the shader, made them more secure (this one is for you matref  :P ), and a bit more powerful.
what next :
-reimplement texture (16*16) and add some new function to handle them proprely + make them even more faster (by the way, I was wondering ben_g, do you think we can do only one division per triangle ? cause right now I do one division by scanline)
-an new lib, combaining some usefull shader.
-a proper  documentation

any suggestion ?

(by the way, I was wondering ben_g, do you think we can do only one division per triangle ? cause right now I do one division by scanline)
I only did the divisions for the top 2 scanlines. The intervals that have to be added to the u and v coordinates are constant for every scanline (as long as you use affine texture mapping, instaed of persfective corrected texture mapping), so you can just re-use the results from them for every other scanline.
Oh, and the reason that I use the results from the 2nd scanline is that the first scanline is very short (often only 1 pixel), so the intervals calculated in it are often inaccurate.

well, I'll try implement this method  :P . The speed will be a lot better then.
