Hi everyone. Fast question. I have two vectors: v1 and v2. v2 is relative to v1, another words v2 is in v1''s coordinate system. How do I get v2 relative to an original coordinate system? Composing angle-axes matrix is a pain in the butt... Is there an easier way? If someone could post source code, I''d really appreciate it. Thanks.

A vector doesn''t have a coordinate system. only one basis vector is defined (v1). thus, v2 is also undefined.

you would have to store all basis vectors corresponding to v1 in order for this to work.
