 Jun18 awarded Teacher Jun6 accepted converting quaternion to vector3 Jun6 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.

May1 accepted associativity of quaternion multiplication May1 asked associativity of quaternion multiplication Apr30 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?
