Fast light processing

[Kilinich]

Since algodoo 1.8.0 became more than twice slower thyme than 1.6.0 I've try to optimize some of my functions.

Here it is simple brightness calculation:

Code: Select all

Scene.my.min := (x)=>{x > 0.2 ? x : 0.2};
Scene.my.fl := (n, r)=>{0.1 + scene.my.min(n(0) * r(0) + n(1) * r(1)) / (r(1) * r(1) + r(0) * r(0))};

n - normal vector to geom surface
r - vector to light source

In that example I've store normal in [friction, restitution] pair.
16 geoms gives ~50FPS on my pc. Can't do better atm.
