Java Utililty Methods interpolate

double interpolate(double a, double b, double d)
interpolate

return a + (b - a) * d;

double interpolate(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));

double interpolate(double oldP, double newP, float partialTicks)
interpolate

if (oldP == newP) {
 return oldP;
return oldP + ((newP - oldP) * partialTicks);

double interpolate(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;

double interpolate(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;

double interpolate(double x1, double x2, double inbetween)
interpolate

return x1 + (x2 - x1) * inbetween;

double interpolate(double x1, double x2, float zeroToOne)
interpolate

if (zeroToOne == 1.0f)
 return x2;
return x1 + zeroToOne * (x2 - x1);

double interpolate(final double min, final double max, final int currentClass, final int numOfClasses)
interpolate

return min + (currentClass * (max - min) / (numOfClasses - 1));

float interpolate(final float prev, final float curr, final float alpha)
interpolate

return (prev * (1 - alpha)) + (curr * alpha);

int interpolate(final int n, final int lastN, final float interpolation)
interpolate

return Math.round(((n - lastN) * interpolation + lastN));
