Not using matricies, using straight up lists.  The equations are here, I use the non-matrix forms.

How is it not projection?  It rotates and everything :D

Perspective projection is different.  Notice how in the screenies in this thread, the back of the box is visually smaller than the front?

So you're telling me this isn't perspective projection?

Wow, that looks right!  Did he use some clever hacks?  Because that stuff is CPU intensive.

No idea, but it should be in the demo programs so you should check it out! :D

Actually, if I remember correctly, the engine already works the way you want it to (other than clipping).  It just reads a list of lines in the form of [x1y1z1x2y2z2]... and then draws them all each render.  So just by editing this, you could get any shape.

Also, perspective 3d is not much more cpu intensive than ortho, it only requires one extra division per z-coordinate.

Hey, kind of a necropost, but I was thinking, with Jacobly's new Floating Point math axiom, this might be able to convert to Axe.

It could definitively be a good project, although since floating points are slow, I wonder if the speed increase from BASIC to Axe will be signifiant at all, if there's even a speed increase althogether?

with 8.8 fixed-point, it's possible to do perspective projection is possible, and doesn't axe supports that?
Fixed-point should be a lot faster than floating point, and might make it fast enough for use in games.

Right, you could use fixed point as well...
