All it does is let you spin a wireframe cube, but hey... math is fun.

Nice! Great to see another person with knowledge of 3D!

Thanks, TN21! It's pretty rudimentary compared to what you're doing, but I'm proud of it and it was good practice.

Yeah, I learned 3D stuff back in Petit Computer. If you need any help, I'd be glad to!

If you use "IF B AND 4" instead of "IF B==4", then you can press multiple buttons and the IF statements will still trigger.

Ahh, thanks for the tip! I knew there must be a smoother way to control it. I'll try adding stick support, too.

I just looked at your projection formula, and it seems really weird, especially when DEPTH is set to higher values. Notice the concave face of the cube on the left. I use X'=X/Z*ZOOM Y'=Y/Z*ZOOM Where ZOOM controls perspective distortion. I usually set it to 256.

Hahah, yeah. That's why I set it so low. I really didn't know what I was doing with projection, so I just tinkered.

Hmm. Well, the tesseract coordinates are easy enough to plot in 3d, but... yeah, this requires research. I hope there's a standard matrix out there.

I modified my 3d engine a bit and divided x, y, and z by w before projecting, and this appeared on my screen. It would be in 3D but my virtual parallax barrier looks horrible in screenshots so I turned it off. There was a lot of extrapolating and pattern recognition involved, since I don't know that much about 4D math.

Hard to tell without motion, but it looks legit from here.
