I have a quaternion coming from a ros tf tree that is representing the orientation of my camera. I am trying to set these values for a blender script to render a scene, but the camera looks into the wrong direction, compared to when I visualize the quaternion within rviz(ros visualization tool). So I assume there is some fixed rotation that I need to apply between the tf exported quaternions and the beldner quaternions, but I'm not sure which one. Example pictures will make clear what I mean:
Now when I enter some example values into blender you can see that the camera look completely into the wrong direction: The tooltip in blender for quaternions says wxyz am I right to assume that this is the order the values need to be entered(I did it this way)?
I'm not sure what the problem is but I assume that my question is what is the transformation between the looking direction of the blender camera and it's z-vector?
