Given: a) two frames of a moving object and euclidean transformation(rotate + shift) between them which aligns projection of the object on the first frame to its projection on the second frame. b) model transformation matrix for the first frame; c) view and projection matrices which are the same for both frames.

How to find model transformation matrix for the second frame? Thanks.

  • Hint: think about how you operate with matrices between two frames. And how you compose two transformations in just one matrix. – Ripi2 Mar 19 '17 at 16:17
  • I multiply them, but how can I use it? If I have only shift transformation(without rotation) between frames, I unproject the same point(for example center of the object) on two frames and find shift in a world space. But how can such approach be applied to a more complex transformation? – Vitaliy Mar 19 '17 at 17:37
