AGN3D heeft een paar screenshots van Unreal met een Creative TNT en real-time volumetric shadows:
Creative Labs is in the process of adapting its Graphics Blaster TNT drivers to provide real-time volumetric shadows for Epic MegaGame's Unreal.
By using the TNT's stencil buffer, Creative's adapted drivers take model geometry and lighting information and then uses this data to create a real-time volumetric shadow that reacts realistically to the light source shined on it. It also takes into account light direction, so shadows are rendered appropriately.
Currently, Unreal is the only game that will support this effect (via a patch), but game developers are more than welcome to talk with Creative Labs with regards to taking advantage of this new technology.
