Effect. An effect affects things.

That's polygonal, not voxel-based, but the height mapping for the mountains is procedurally generated using a similar fractal algorithm to the early voxel-based games that Lucasfilm developed for Atari's 8-bit computers (and subsequently ported to every other computer under the sun). If you aren't familiar with these fine games, you should be: Rescue on Fractalus was released first and is the most popular, The Eidolon is the most sophisticated, and Koronis Rift is a clunky, complicated mess that's great too. (If you have the time, look up the lavish manuals at Atarimania.) Rescue on Fractalus is actually relevant to the Jaguar - not only is Cybermorph essentially an (underachieving) update of it, but I also just found out about an impressive-looking homebrew remake for the Jaguar called Fallen Angels.

They're just limited. There are big reasons that you only see them used for smoothly rolling hills, even in what heyday they had.

The main issue is that the smoothness you see in these games is because the voxels are calculated using a simple height map. This means that nothing can overhang or overlap anything else. It is possible to use them in full 3D, but it takes a lot more processing power and is incredibly inefficient compared to polygons. As it is, only the terrain can be voxels, and any moving objects have to be either sprites (in earlier games) or polygon models (in later games).

As for animation, even if we put full 3D on the table and give ourselves the opportunity, the main challenge in animating with voxels is that each frame has to be an entire model, just like how each frame in a pixel-based 2D game's animation uses an entire sprite. It's much less of a waste to simply move polygons around with a skeleton.

In any case, the way that games are now, even the ground that you walk on is always so lushly animated that voxels would be useless for anything you could actually see, and rendering them in 4K would be a complete waste of power if you wanted anything besides hills in your level design. There's also the matter of shaders, which use vector calculations that I can't imagine playing nicely with voxels. Even if voxels had gained a bigger foothold in the '90s, they'd still be obsolete today. (I believe that they're still used in medical imaging, though, since they don't have to do anything, just represent 3D space.)

[Addendum: This post used to say something very silly about voxels' efficiency before I remembered that these games use raycasting, which scales linearly in processing demand with resolution, which is the entire reason that a game like Comanche was viable in 1992 in the first place. Me dumb.]


Thanks for the write up, interesting reading.

How about Black Ice White Noise? It was supposed to be a free roaming cyberpunk adventure on the Jag CD. Got to early alpha stages before Atari shut down the Jaguar's development department. Someone found a prototype, and I think you can still buy a copy: http://www.bjwest.com/BIWN/ There's not much to do, but it looks like it could've been interesting. Still not my style, but a refreshing break from FPS games.

The developer's still around; he makes low-budget movie FX now: http://kelpentertainment.com/web/

Brett Hull NHL Hockey

Not much to say about this one; I'm not a major sports fan. Nice 3D-ish fx tho. Still not sure if it would've been able to stand up against PSX and N64 sports games.
