| 2013-01-08 15:49:21 -0600 | asked a question | Rotation from getPerspectiveTransform Hi, I have an image of a rectangle. I'm using getPerspectiveTransform() to get the 3x3 matrix to get information about image rotation, tranlation, skew etc. Now, what I want is to get angle of rotation around X, Y and Z axis of that rectangle (for OpenGL). Any ideas how to get these angles? |
