Material Manipulation Using the Leap Motion

Thinh Nguyen

Osaka University

July 24, 2013


Current progress

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


Current progress continued

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.


Next week

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.
