Class CamToWorldDirection

java.lang.Object
com.j3d.engine.math.rot.CamToWorldDirection
All Implemented Interfaces:
RotationMatrixDirection
public class CamToWorldDirection extends Object implements RotationMatrixDirection
Implements the RotationMatrixDirection interface to create rotation matrices that transform a direction from camera space to world space.

This is the standard transformation used to orient an object (like a camera) in the world. For example, applying these rotations to a base "forward" vector (e.g., [0, 0, 1]) will point it in the correct direction in the world scene.

The order of multiplication typically matters. For a standard Tait-Bryan rotation (yaw, pitch, roll), the combined matrix would be M = Yaw * Pitch * Roll.
