SLOOOOOOOOOOOOOOOOOOOOOOOOOOOOW *death metal*

So many checks. Also, if you modified GCore again I'm going to kill you.

you know what ? GCORE won't be modified. I am talking about GPOLY lib and GCORE's function allows me to have such pipeline.

Also why are you telling it is slow ? There aren't many check. Even if I put in place a z-buffer, it will be only a 1536 bytes buffer, requiers only one check per 8 pixel (artifact may show up, but it mainly works great).  Stencil buffer is simply implemnted using a 8 bit and per 8 pxl.
Fragment shader could also implement this by there one.
This pipeline is not slowest than the previous I use - exept for the triangle routine. I've made test : it is slighty slower than "normal" (balck/white) filling - but faster then texturing and allow generating fragments.
Ok, one thing is kindy bothering me : slice shifting (like in pseudo slime I've made) will be much more difficult. But I can add an other special shader for it.

Sooooo... here my last result, and I am pretty proud of it. This a standard cube runing at almost 37fps  :crazy:

The max is 38.28 fps at some particular position  :P



More is coming soon ....

I have improved the vertex shader thing, so now it's allowing making a particule system only based on shader.
And a little screen  :D   (very simple : read random, particule system)

No eyes candies for the moment, but I've just run speed test.
 
Clock Speed : 6 MHz
VBO : No VBO active
 VERTICES     MAX      AVERAGE
1024 vertices   1.2 fps      1 fps
512 vertices     2.5 fps      2 fps
256 vertices     4.5 fps      4 fps
128 vertices     9 fps         8 fps
64 vertices       17 fps       15 fps
32 vertices       27 fps       25.5 fps
16 vertices       45.4 fps    41 fps
8 vertices         64 fps       60 fps
 
64 vertices are perfectly possible for real time  :P

It sounds good, but what is this test really based on? Is it only transforming vertices from world space to screen space or is it drawing stuff too?

Transforming the vertices and drawing 2*2 black square at the screen position.

What if you display 8 spinning cubes (filled)?

Filling still doesn't work great with my current update. I have to fix it  :P , and it always have been slooow.
However, if I display 8 standard cubes (wired), the speed is 7.4 fps (96 lines, 64 vertices)
