Features:

* Opacity
* Transformations
* Collisions
* Anti-Aliasing
* Texturing

It would be really cool if they would be anti-aliased polygons like in flash.

That could be done using a memblock bitmap.

Yeah, that's the only way to do it. DarkBASIC may be slow, but directly accessing a memblock instead of using the higher level commands might make up for it somewhat. Basically, anti-aliasing is done one of two ways:

1) Fullscreen post-processing effect (Crysis)
2) With each polygon (Flash)

I don't know whether 1 or 2 is faster. Then again, what do I care? You're the one programming it. I'll just wait and see. It might be cool to use this technology to add some cool special effects to games. Obviously, it would be too slow to completely replace DarkBASIC's built-in 3D commands for large complex scenes, but as some sort of effect, it might be interesting. It would complement the regular 3D graphics.

I'm working on the rotations and scaling which is taking a bit of redesigning of the memblock structure. But I just wanted to post this

Look at the FPS: I can't believe drawing a wireframe polygon is so slow! It's two-thirds the speed of my opaque polygons. The built-in line command really eats resources!

[edit]

I'm trying to write some functions that just read values from the memblock and return them to make it easier to use, like this:

The last one is the only one that works. Is there really no way to avoid assigning another variable?
