Class QuickAndDirtyAngle

java.lang.Object
  meshi.geometry.Angle
      meshi.geometry.QuickAndDirtyAngle

All Implemented Interfaces:

Updateable

public class QuickAndDirtyAngle
extends Angle

Allows the use of approximated arc-cos function. The use of the standard Math.acos function is the default.

Method Detail

acos

public final double acos(double cos)

An approximated fast arc-cos function that uses the ArcCos class. Note that the static method ArcCos.useFastArcCos() should be called in order for the approximation to take affect. Standard Math.acos is the DEFAULT

Overrides:

acos in class Angle

Parameters:

cos - value

Returns:

arccos value
