Outer movements largely for solo cello use its capacity for multitexturing
to evoke the didgeridoo (that instrument again), crystalline upper strings provide glacial harmonics, and funky percussive string patternings bring an Indonesian feel to central movements.
This can be done by multitexturing the normal map texture with a normalization cube map, that is rotated according to the direction of our light source .
The multitexturing step must be repeated for each light source in our 3D scene.
Other new features include support for multitexturing
, bump mapping, and cube mapping.
Other features include 32-bit internal true colour resolution, support for 8-layer multitexturing
, DXTC texture compression and Direct3D compliant environment mapped bump mapping.
By doing only what is absolutely necessary, and by keeping as much 3D processing as possible on-chip, PowerVR's combination of Tile Based Rendering, 32-bit True Color, 8 Layer Multitexturing
and Hidden Surface Removal allows maximum performance to be extracted from the available memory bandwidth.
