Have a look a this (now classic) cart:

That said, don't get your hope too high (and certainly not @60fps)!

Ya @freds72 it uses a simmilar technique. Anyway, I'm looking for some 30fps or 20fps, but it's a bit hard to get this result as plotting to the screen is pretty slow.

Had a second look at your code - there is a lot that can be optimized!

I don't know what is your intent, but make sure you have the fastest polygon rasterizer before going into texture mapping, like:

• efficient clipping based on face winding
• efficient vertex representation (vertex sharing between faces for one)
• optimized transform loop (e.g. use matrix to express multiple transforms, not multiple function calls)
• use lua syntax as much as possible. Ex:

x,y=y,x

is valid and doesn't require an additional variable
