managed to get a basic curve approximation working in geometry nodes

lesssssss goooooooooo

on my surfacing shit again.
fixed some wrong curvature evaluation on the visualizers and pinned the end curvature values for bridging

all of this with some silly billy numbers :)
#b3d #geometryNodes

surface bridging with tangent continuity at isoline. Follow me for more made up sentences

added a vertex sort so i can have a nice mirror modifier 🐳

:3

had to look closely at how i was calculating the derivatives past the first one. turned out i forgot some additional iterations. but this looks alright now. at least i think so 🙃

curvature comb 🪮

#b3d #geometryNodes

revisited my previous trimming routine (which was flakey at best) and revised it with the triangle intersection

your excel colleagues are gonna love geometry nodes

triangular intersection from displaymesh -> resampling surface UVs -> Reevalution -> planar intersection

from the triangle intersection i resampled the resulting line, evaluted the points for both surfaces and just did a simple planar intersection between both normals. not super exact. but for viewport purposes i think this is fine
