Description

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

Method

doubleinterpolate(double a, double b, double d)
interpolate 
return a + (b - a) * d;
doubleinterpolate(double fromAngle, double toAngle, double ratio)
Interpolates angle according to rate, with correct 0->360 and 360->0 transitions 
double delta = toAngle - fromAngle;
if (Math.abs(delta) > 180) {
    toAngle += delta > 0 ? -360 : 360;
return normalize(fromAngle + ratio * (toAngle - fromAngle));
doubleinterpolate(double oldP, double newP, float partialTicks)
interpolate 
if (oldP == newP) {
    return oldP;
return oldP + ((newP - oldP) * partialTicks);
doubleinterpolate(double p0, double p1, double p2, double p3, double t)
Interpolation of Catmull-Rom Spline 
double v0 = (p2 - p0) * 0.5;
double v1 = (p3 - p1) * 0.5;
double t2 = t * t;
double t3 = t * t2;
return (2.0 * p1 - 2.0 * p2 + v0 + v1) * t3 + (-3.0 * p1 + 3.0 * p2 - 2.0 * v0 - v1) * t2 + v0 * t + p1;
doubleinterpolate(double x, double x1, double y1, double x2, double y2)
Interpolate a value between two points. 
double alpha = (x - x1) / (x2 - x1);
return y1 * (1 - alpha) + y2 * alpha;
doubleinterpolate(double x1, double x2, double inbetween)
interpolate 
return x1 + (x2 - x1) * inbetween;
doubleinterpolate(double x1, double x2, float zeroToOne)
interpolate 
if (zeroToOne == 1.0f)
    return x2;
return x1 + zeroToOne * (x2 - x1);
doubleinterpolate(final double min, final double max, final int currentClass, final int numOfClasses)
interpolate 
return min + (currentClass * (max - min) / (numOfClasses - 1));
floatinterpolate(final float prev, final float curr, final float alpha)
interpolate 
return (prev * (1 - alpha)) + (curr * alpha);
intinterpolate(final int n, final int lastN, final float interpolation)
interpolate 
return Math.round(((n - lastN) * interpolation + lastN));
