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).

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.

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).
