The raycaster demo shows minkowski sum of a cube and a cylinder. The cube is rotating, so the minkowski sum deforms.

Other demos show islands for deactivation, time of impact between two rotational+translational moving objects (*), gjk with visualization of the final subdistance simplex.



(*) Absolute (worldspace) motion, so it can be generally used in a physics engine, in contrast to relative motion methods. A minkowski method which updates both orientations every iteration is in the works.
So this is imilar to Gino van den Bergens 'raycast against convex...', but now with angular component and not relative motion. Another application of conservative advancement, as described in Mirtich's PhD thesis.
