Description

The list of methods to do Lerp are organized into topic(s).

Method

doublelerp(double start, double distance, double factor)
lerp 
return start + (distance * factor);
doublelerp(double v1, double v2, double amt)
lerp 
return v1 + (v2 - v1) * amt;
doublelerp(double x, double x1, double x2, double q00, double q01)
lerp 
return ((x2 - x) / (x2 - x1)) * q00 + ((x - x1) / (x2 - x1)) * q01;
doublelerp(double x, double x1, double x2, double q00, double q01)
Linear interpolation. 
return ((x2 - x) / (x2 - x1)) * q00 + ((x - x1) / (x2 - x1)) * q01;
doublelerp(final double a, final double min, final double max)
lerp 
return min + a * (max - min);
intlerp(final double percent, final int startColor, final int endColor)
lerp 
if (startColor == endColor) {
    return startColor;
} else if (percent <= 0.0) {
    return startColor;
} else if (percent >= 1.0) {
    return endColor;
final int r = (int) ((1.0 - percent) * (startColor >> 24 & 0xFF) + percent * (endColor >> 24 & 0xFF));
...
floatlerp(final float a, final float b, final float f)

With this function you can find the value that equates to the position between two other values for a given percentage. 

return a * (1.0f - f) + b * f;
floatlerp(final float percent, final float startValue, final float endValue)
lerp 
if (startValue == endValue) {
    return startValue;
return (1 - percent) * startValue + percent * endValue;
floatlerp(final float x, final float x1, final float x2, final float q00, final float q01)
lerp 
return (x2 - x) / (x2 - x1) * q00 + (x - x1) / (x2 - x1) * q01;
floatlerp(float a, float b, float f)
Linearly interpolates between two floats 
return a + f * (b - a);
