Hi, I'm trying to add cameras to the scene (dropping models across the scene) and the user could drag them or rotate them and change its parameters. All works good for the first time, however, I lose track if the user rotates the camera representing object. I'm banging my head with simple math but I'm unable to figure out how the camera's center/up vector change if the camera object rotates. I put the eye to where the node is translated to.
I tried to figure out the rotation angle so that I could initialize the camera with the original parameters for the center and up and then apply rotation to the model view matrix but it doesn't seem to make the camera look at, in the correct direction. I'm using daggers for rotating and translating the node. Tried looking at source for some manipulators but could not understand much. Sorry for the noob question but would be glad if anyone could help. Thanks, mots
