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.
• 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
• 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.
