Here is a list (from Wikipedia) of games using Voxels:
“Infinite detail is basically proceduralism and you can do that with polygons, voxels, atoms, splats, whatever. I don’t think the notion of infinite detail is actually all that important. It is more important to be able to get the broad strokes of the artistic vision in there, and if you take uninspired content and look at it at the molecular level, it is still uninspired content.“
C4 Engine is a game engine that uses voxels for in game terrain and has a voxel editor for its built in level editor. C4 Engine uses a LOD system with its voxel terrain that was developed by the game engine’s creator. All games using the current or newer versions of the engine have the ability to use voxels.
Atomontage is a hybrid (voxel & polygons) game engine project.
Upcoming Miner Wars 2081 uses their own Voxel Rage engine to let the user deform the terrain of asteroids allowing tunnels to be formed.
The videogame Amok for the Sega Saturn makes use of voxels in its scenarios.
The computer game Vangers uses voxels for its two-level terrain system.
The computer game Thunder Brigade was based entirely on a voxel renderer, according to BlueMoon Interactive making videocards redundant and offering increasing detail instead of decreasing detail with proximity.
Master of Orion III uses voxel graphics to render space battles and solar systems. Battles displaying 1000 ships at a time were rendered slowly on computers without hardware graphic acceleration.
Build engine first-person shooter games Shadow Warrior and Blood use voxels instead of sprites as an option for many of the items pickups and scenery. Duke Nukem 3D has an optional voxel model pack created by fans, which contains the high resolution pack models converted to voxels.
“I’ve revisited voxels at least a half dozen times in my career, and they’ve never quite won”
The bottom line: ray tracing is probably going to feature in our games development future, as is tessellation, but we simply don’t yet have the horsepower to make them do things any better than what Carmack has put together over the last six years in the lead up to Rage.
