Class SinCosLUT

java.lang.Object
  toxi.math.SinCosLUT

public final class SinCosLUT
extends java.lang.Object

Lookup table for fast sine & cosine computations. Tables with varying precisions can be created to which input angles will be rounded to. The sin/cos methods can be used with both positive and negative input angles as with the normal Math.sin()/Math.cos() versions.
