Plotcube - a quick little 3D experiment


Recommended Posts

You guys might like this, so I thought I'd post it here as well:





A quick experiment with 3D stuff on the Atari 2600 VCS. I felt inspired by the plotsphere in Sphaera Stellarum. The effect is table driven, 95 frames and sadly uses the entire 4k ROM, leaving no room for anything else.


Generating the point data on the fly looks to be infeasible, considering there's barely enough time to Y-sort the points during VBLANK, much less do any 3D calulations.. Hence I decided to simply release this as-is.

I see there is not much going on above and below the cube. Maybe that space can be used for something nice?

Certainly. The problem is lack of ROM space for anything else. I've worked out how to cut the size of the tables down down enough to make something like this a pratical effect.

I might incorporate something similar in a future prod..
