lerp static method
From Closure:
- Performs linear interpolation between values a and b. Returns the value
- between a and b proportional to x (when x is between 0 and 1. When x is
- outside this range, the return value is a linear extrapolation).
- @param {double} a A number.
- @param {double} b A number.
- @param {double} x The proportion between a and b.
- @return {double} The interpolated value between a and b.
Implementation
static double lerp(double a, double b, double x)
{
return a + x * (b - a);
}
