  1. Material Manipulation Using the Leap Motion Thinh Nguyen Osaka University July 17, 2013

  2. Current Progress • Deformed surface materials using a ray casted technique. Runtime is smooth with <8 fingers being raycasted onto the meshes. • Accuracy is very good when fingers in normal horizontal positions. Bad for when user instinctively tries to rotate hand vertically, also bad when user tries to move a hand object on top of another hand object. • Currently geometry is only being scewed outwards (Faces only as well).

  3. Current Progress Continued. • Geometry moves outward based on the finger raycaster (right now simply negates the finger ray and pulls face of geometry outwards towards that location). • Made a new finger base class and a variety of functions to decouple fingers and hand objects, to make gesture recognition easier and possibly hand independent if need be.

  4. Next Week • Finish inward face geometry manipulations. Clean up and comment a lot of the current code, come up with a better system for debugging the javascript. • Increased complexity of ongoing code is making debugging javascript quite a pain. • Afterwards trying to come up with a way to actually add/subtract vertices (not just use existing vertices, IE: not just dealing with surfaces purely).
