Editing Build (game engine) (section)

=== Voxels ===
Later versions of Ken Silverman's Build Engine allowed game selected art tiles to be replaced by 3D objects made of [[voxel]]s. This feature appeared too late to be used in ''Duke Nukem 3D'', but was seen in some of the later Build Engine games. ''Blood'' uses voxels for weapon and ammo pickups, power-ups, and eye-candy (such as the tombstones in the "Cradle to Grave" level, some chairs, and a [[crystal ball]] in "Dark Carnival"). ''Shadow Warrior'' makes even more advanced use of the technology, with voxels that can be placed on walls (all of the game's switches and buttons are voxels).

For several years, Ken worked on a modern engine based entirely on voxels, known as ''[[Voxlap]]''.
