  barsuift.simLife.j3d.util.ProjectionHelper

public final class ProjectionHelper
extends java.lang.Object

Helper class to "project" a point on the "ground".

Projecting a point means setting its Y value to 0. Thus a (1,2,3) point is projected to (1,0,3).

The new point is the same one but on the X-Z plan.
