Abstract
Specifying 3D rotations of shapes around arbitrary axes is not easy to do. We present a new method for this task, based on the concept of natural local rotation axes. We define such axes using the 3D curve skeleton of the shape of interest. We compute effective and efficient approximations of such skeletons using the 2D projection of the shape. Our method allows users to specify 3D rotations around parts of arbitrary 3D shapes with a single click or touch, is simple to implement, works in real time for large scenes, can be easily added to any OpenGL-based scene viewer, and can be used on both mouse-based and touch interfaces.
