  1. Material Manipulation Using the Leap Motion Thinh Nguyen Osaka University July 24, 2013

  2. Current Progress • Skewed geometry inwards using raycasted techniques, runtime quite slow with >5 rays. • Worked on coupling adjacent face surfaces (nearby neighbor faces of the mesh also getting gradual changes and not just the one the raycaster selected). • Optimizations to rendering loop when finger objects are too far away from mesh object

  3. Current Progress Continued. • Geometry moves both inward and outward now. • Slight bug when moving inwards too fast, once raycaster is already past the surface mesh the raycasted technique does not work anymore until the finger ray is outside again. • Read a variety of VR sculpting papers to see what types of techniques and problems they were having.

  4. Next Week • Come up with a way to actually add/subtract vertices to the existing mesh. • Finish up coding the face coupling in the mesh class. Solve the “Finger moving in the mesh too fast” problem. • Work on camera rotations and movements to work with mesh manipulation.

  5. Local coffee shop(she gave us a bunch of free stuff!)
