Techylah,
Graph only in basic form is working with your suggestion of the VB6 picturebox drawing lines.
I am now looking in the 2DNTgraph.ocx to see if I can get this to work too as it more fancy and has more features.
But for the time being the simpel graph exactly shows what we are doing with X and Y points although it is not using the curvePower yet ;-).
I just tested the curvePower line.
//lookupTable[i] = map(i, switchpointXValue, 255, switchpointYValue, 255 ); // this could get replaced by a curve after all is working
lookupTable[i] = (int) (0.5 + (switchpointYValue + pow( map(i, switchpointXValue, 255, 0, 255 - switchpointYValue ) / 255.0, curvePower/10) * 255.0));
As soon as CP value is 1 I can reach 255 as maximum
When I raise CP to 2,4 value the maximum is getting lower. The higher CP the lower the maximum.
Hum.
