Class Matrix4d

java.lang.Object

com.mousebird.maply.Matrix4d

public class Matrix4d
extends java.lang.Object

This encapsulates a Maply4d matrix. In general, we don't manipulate them, but we do pass them around.

You'll probably only encounter them if you subclass MaplyController and take over the gesture handling.
