Hello everyone, I am using a SimpleViewer. I set up a post draw callback on its main camera. In it I read the camera eye, center, and up vectors. Initially, this give me (0, 0, 0), (0, 0, -1), and (0, 1, 0) respectively. This is what I expect and it gives me a particular view of my scene.
Now I add a trackball manipulator to the main camera and set up the view similar to what I had previously. When I read back the data it is quite different. I would have expected the same camera position / orientation than before since what I see is similar. Unless the trackball affects the model position / orientation and not just the view ? How can I use a trackball and read back in the post draw callback the values I want ? sincerely, Bill
