Jun 6	accepted	converting quaternion to vector3
Jun 6	comment	converting quaternion to vector3 @StevenStadnicki yes a vector is 'baseless', but at the same time not. A vector is by definition a magnitude, and a direction, but what makes them baseless is that they can be placed anywhere, and still have the same meaning. the same way that a quaternion is baseless as it is only an orientation that can be applied to any thing. my goal was to be able to use a quaternion to obtain a `vector3` such that something like a forward, or look `vector` could be found, but thanks to some reasoning work a Vector3 can be treated as a quaternion which simplifies the problem to a quaternion identity.

May 4	comment	associativity of quaternion multiplication I never took a any course on proving mathematical properties, so I will have to take your word for it on this, and according to the up-votes I am presuming that it is accurate.

Apr 30	comment	converting quaternion to vector3 @rahulnarain from my understanding a quaternion gives an orientation about a point, and then getting a second point in the direction of that orientation would yield a vector, or am I missing something?

Apr 17	comment	rotating a matrix that somewhat answers the example (being that it is a square matrix), but what about the general case which will be a "rectangular" matrix where transpose has no meaning
