Detailed Description

represents a frame transformation in 3D space (rotation + translation)

if V2 = Frame*V1 (V2 expressed in frame A, V1 expressed in frame B) then V2 = Frame.M*V1+Frame.p

Frame.M contains columns that represent the axes of frame B wrt frame A Frame.p contains the origin of frame B expressed in frame A.
