Light shafts

This is a new volume_shaft_base material on ObjectVolumeBox:

PlayStation3 Unigine status X

Each rendered triangle of static and skinned meshes is culled by view frustum and front/back face tests on SPU. Skinning is performed entirely on SPU with both ordinary and dual quaternion skinning modes available. Vertex buffers for particles are generated on SPU with view frustum culling. Particles can be sorted by depth on SPU. Particles are simulated on SPU with awesome performance.

PlayStation3 Unigine status IX

Heap of code for view frustum and back face SPU culling, but result is wonderful.

SPU skinning with view frustum and back face culling (30ms per frame)
