A couple of 2017 tests/prototypes using Shephard/IDW interpolation[1] to compute "soft" voronoi cells. Reposting this after npub125jderklq9z7zwqvguhvwcpv3end5rev8lpel932y6t6ru4046gsua4as0 (npub125j…4as0) was mentioning this method for 3D modeling in recent days. Coincidentally, these tests were for something v. similar, i.e. outsole traction pattern geometry generation — the exponent used in this method acts an easy-to-grok parameter to control softness/sharpness & level of detail... Unlike these examples, which are only using point samples and colors, the idea was to interpolate between line geometries to create a relief surface. E.g. applied to an outsole, we could configure the interpolation to produce softer shapes in the heel region and more detailed ridges in the front foot, where traction is needed most... In the end I didn't use this specific interpolation method for performance reasons and switched to another approach to compute an SDF for v. similar results (see recent posts from yesterday).
