Detailed Description

Defines a transformation from graph space to world space.

This is essentially just a simple wrapper around a matrix, but it has several utilities that are useful.

Vector2 IMovementPlane. ToPlane ( Vector3 p )

private

Transforms from world space to the 'ground' plane of the graph.

The transformation is purely a rotation so no scale or offset is used.

For a graph rotated with the rotation (-90, 0, 0) this will transform a coordinate (x,y,z) to (x,y). For a graph with the rotation (0,0,0) this will tranform a coordinate (x,y,z) to (x,z). More generally for a graph with a quaternion rotation R this will transform a vector V to R * V (i.e rotate the vector V using the rotation R).
