XForm Building Blocks (XBB)
C++11 library to enable composition of 3d transforms
- Use minimum number of trigonometric operations, multiplications, divisions, and additions
- Take full advantage of known constant's through multiple transform concatenations (multiplications),
- Reverse order of concatenations vs. performing an expensive "inverse".
For motivation, an introduction, and practical results see Slashing the Cost of 3d Matrix Math using X-Form (Transform) Building Blocks
