Some continuation on my previous posting on transformation
Attachment 32525
Hello, this is some continuation of my previous posted topic on transformation. I have attached two pictures of rotation of different axes, i.e. X, Y and Z. Z rotation is the projection on XY plane for two different Z rotation. It shows how the length of the axis varies depending on Z rotation. Now my question is, from this information is it possible to figure out rotation of Z axis. Here as rotation is on XY plane, the length of X and Y axis does not vary, but that of Z-axis varies.
Thanks in advance.

Your definition of "rotation" is not clear! How would it be that "Z rotation is" something "for two different Z rotation"? :confused:

As this isn't specifically a c++ question, you might get more guidance if you posted to the Algorithm forum.

If what you mean is... from a given projected image (result) and a given input model figure out the amount of rotation along each axis:
then no this isn't unambiguously solvable for all possible input cases.
In the 3D to 2D projection phase, information is being lost.
