Cinema 2.0 follow-up with Jules Urbach - LightStage

Yeah but weren't the AMD Cinema 2.0 demos made out of voxels? No game engine runs with them, it's always just polygons. :(

I've played games that use voxel rendering. Back in the day Comanche used them. Crysis uses a Voxel based terrain generating system and converts it to poly. For now voxel is most applicable in movies, but we don't know how games of the future will look.

Data can be converted from one format to another. I guess it depends on the direction of game engines to what data form you start with.
The big issue with Voxel's is memory and associated memory latency.

procedurally DX 11 can generate complex geometry out of relatively sparse data sets

A DX11 hardware tessellator's will be using patches for curves or regions, not just triangles, but quads. Tessellation can also generate lines for hair.

The direction is to photo realistic games so starting from a very high data set is a no brainer. Patches can be extracted from such high quality data sets as are used in light stage.
