continuous curvature

[jaredjennings]

https://reddit.com/u/Thatothermofo has brought to my attention the idea of continuous curvature in product design. https://www.reddit.com/r/MechanicalKeyboards/comments/b3soxi/once_youve_seen_it_you_cant_unsee_it/

At present there are discontinuities in the curvature of the sides and bottom of the keyboard at every keyswitch: it is a 3d piecewise linear object, not defined as a curve.

To fix, stop taking the hull of this and that, and instead define their shapes as continuous functions, whose first derivatives are constrained to be zero, for example, within 2mm of a keyswitch hole. Stopping using hull would enable the use of Five to model the keyboard, although defining and evaluating such functions as these make me think more of solving equations (like CFD or FEM) than drawing or describing (like CAD, POVRay, OpenGL). Either way it may be so much change as to compel a completely different project.
