A transform is a location and rotation. Its used because in a hierarchical system both influence another.
@jagwire said: @pspeed this is fantastic! With your permission, I'd like to use this in development of some instructional materials for co-workers. I'd also encourage this be saved/published in the JME3 mathematics documentation...even if just for background information.
Yeah, that’s fine.
@jagwire said: To continue the discussion one step further, we have this transform matrix, and JME3 spatials have a Transform object including a vector3f for translation, a quaternion for rotation, and a vector3f for scale.How do we convert from one to the other?
Is there a utility class to interpret a transform matrix into a Transform object and vice-versa?
Going the other direction (from Matrix4f to Transform) is a little trickier. On the surface if seems not so bad but if you must take scaling into account then it gets trickier. I think if you were to grab the 3x3 rotation matrix from the Matrix4f that you could deduce scale from it. But I haven’t tried it.
