Hello there!

This is my first day as Qt developer and so far I'm very impressed! Thanks for the great libraries, the comprehensive documentation and an awesome GUI designer.

Anyways. My task is to display a sketch of a human skeleton in different poses on the screen. The user gives joint angles to the software and then the skeleton changes its pose. Since I have no experience in Qt so far, I would like to listen to your advises as to what's the best way to accomplish this.

It's not a graphical issue. I can just use lines and circles to mark the limbs and the joints. I will need a 3D representation of the skeleton and calculate the positions of the limbs by applying the joint angles to the model using...AffineTransformations? And then I need a 2D projection of the model which then I actually show on the screen. Can I even visualize the 3D model right away and make it turnable by mouse drags? I think you get the picture of what I want. What classes should I be looking into?

Thanks a lot
Cruz
