Class Acceleration3D

java.lang.Object
org.opentrafficsim.core.math.Acceleration3D
All Implemented Interfaces:
java.io.Serializable
public class Acceleration3D
extends java.lang.Object
implements java.io.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.
