This is pretty cool... I can't wait to play around with it.
You can already start playing with it here  http://ourl.ca/20032/366887  ;)

Anyway, sorry for the respond time, but I got pretty sick. Hopefully, I am better now, but I haven't really progressed.  :(

backface culling as been reimplemented ! However, I started to have a big (!) problem : compiled source, with all option activated (texture+shader) are being pretty large : almost 6500 bytes....  <_<

Anyway, a little screen : (and yes this is at 6MHz +-5fps , pretty cool isn't it ?)

The texture moves a bit funky when you move the perspective. Take a look at it.

yeah, I know. It's due to affine texture mapping - and there isn't many way to correct it ( there is one but it slowwwww).
So, with this resolution, I guess it's still ok.

TheMachine: you might want to compile it as an app with #ExprOn (if you haven't already)

See what happenes to the speed after that, and if it's too slow, use crabcake for the huge binary.

Guess anyway that 3D will mostly be used in very big project, so crabcake is fine  :P

I am on it, as well as some sort of gouraud shading : one lightning value at each vertex, and some interpolation in the triangle  ;D

yes, basically, it's not so diffcicult, because the dithering I apply is on pxl level. If I treat black texture part as a maximum lightning value, and white as the lowest + ambient value, applying the dithering algorithm will give me a combinaison of texture and lightning :P . However, speed will be very affected.

combinaison of both dithering and texturing. Note that this is at 15MHz. 6MHz is not *that* slow, but the screen is  faster and look better like this  ;D



and thanks Xeda !
