I have some code I would like to optimize using precalculated value table to avoid redundant operations.

Here is the code, it's pupose is to set a moving particle's color based on its speed :

2.     float vRatio = vel.mag()/MAX_VEL;
3.     float cLevel = TWO_PI*vRatio;
4.     if (heatVision) 
5.     {
6.       //float rPhase = TWO_PI/4;
7.       //float gPhase = 3*TWO_PI/4;
8.       float bPhase = PI/2;
9.       int R = int(255 / (1 + pow(2.718, 10 * (0.4 - vRatio))));      //int(128*sin(cLevel*0.5-rPhase)+127);
10.       int G = int(220 / (1 + pow(6, 12 * (0.8 - vRatio))));            //R-int(128*sin(cLevel*0.25-gPhase)+255);
11.       int B = int(128*sin(cLevel*1.35-bPhase)+127);
12. 
    
13.       pig = color(R, G, B);
14.     } 

I would like to pracalculate a table of R, G and B values using  255 values of vRatio (from 0 to 1) and then call each value based on closest match to vRatio at runtime.

I'm guessing I need to compile this table at start time and save it in an extarnal file but I'm at a loss on how to accomplish this.

Your help is greatly appreciated!!! I will post the full source once it is complete.

Thanks,
