All Implemented Interfaces:

Serializable

public class Acceleration3D
extends Object
implements Serializable

A 3D acceleration vector, decomposed in X, Y, and Z-acceleration with easy conversion from and to a spherical coordinate system.
Physicists and mathematicians do not agree on the meaning of theta and phi. In this class the convention in the physics domain is used:

• theta is the angle from the z direction.
• phi is the projected angle in the xy-plane from the x direction.

N.B. In the geography domain yet another convention is used.
