Pseudo-haptics: Kohli's redirected touching #30

Closed bjrtx closed 5 months ago

See e.g. Luv Kohli's PhD thesis at https://doi.org/10.17615/34cy-pt44. Already implemented: ThinPlate interpolation (2D positions x, values y) => function f (Vector2) => float such that f minimizes the bending energy among interpolations of (x, y).

Next items:

finger-tracking solution (incl. finger shadow casting)
mechanism for inputting (x, y)
~from 2D interpolation to 3D/nD (easy)~ done

Current solution suffers from strong numerical instability. Possibly compare to other implementations.

Solved.
