Module library
Contains a list of useful math and helper methods that would be slow to implement in Lua, and which are given here as fast C++ implementation.
Functions
| systemResolution3 (vec_c1, vec_c2, vec_c3, vec_c0) | Solve the 3D linear system M*x=c0 where M is defined by its colum vectors c1,c2,c3. |
| systemResolution2 (vec_c1, vec_c2, vec_c0) | Solve the 2D linear system M*x=c0 where M is defined by its colum vectors c1,c2. |
| getPointOnScreen (worldPos) | Returns the position of the given point in world coordinates system, on the game screen. |
| load () | Unknown use. |
