High-throughput 3D rotations and normalizations
Thomas A. Lang, E. Antelo · 2001
We present hardware primitives for 3D rotation and vector normalization for high-throughput 3D graphics and animation. The primitives are based on the 2D and 3D CORDIC algorithms, in contrast to more conventional mac-based engines. Also considered are conversions among rotation representations and rotation composition based on the same primitives.
