So i've been working in an app for the last couple of months. For a specific part i need to dislay different faces of a cube-like object. I have some questions about how the rotation works.
When you pass the parameters roll, tilt, and heading for rotate to the model, are you doing a world rotation (the whole "scene") or just the object (based on the origin that you define in the 3D modelling process)? Is rotation imposed or "additive" (if i set the values of rotate, get a rotation, then modifiy it somehow (like you do in the snaptoscreen example in the sdk by using a gesture), and then reset the parameters to those i started with, Will i get the same display as in the first step?).
Those are the questions I have for know. I really like this subject and I am open to discussion. Maybe share some of the hacks (even if they are mental) that you have found to do this transformations easier.
Have a nice day :)
