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
