fastapprox.h and function curve

[ziaoang]

Hi BazkieBumpercar,
There is a function called "curve" shows many times in the code, but I can not find its definition. It seems come from fastapprox.h, but no this file included.
Could you give the definition of this function "curve"?
Thank you~

It's in the engine, the blunted2 project (also on github), in src/base/math/bluntmath.hpp
Here's the definition:

inline float curve(float source, float bias = 1.0f) { // make linear / into sined _/-
    return (sin((source - 0.5f) * pi) * 0.5f + 0.5f) * bias + source * (1.0f - bias);
}

So it will make a linear line into a nice sine curve :)

Cool, I find it in the blunted2 project~
