Fascinating, thanks for sharing! Would be cool to print out some samples and compare your results to the actual physical impression. If commercial 3D printers even have the resolution to capture the subtle differences..
All good! I’ve printed some of these corners on a FDM but it was fairly inconclusive as I had some printing artefacts. Getting some sections machined or cut would be better.
Excellent Andrew! I have always looked at how a spot highlight accelerates and decelerates when transitioning from straight line to curve! What you have done here with tactility is in some sense the same thing! I presume the best result for tractility would give the best result for highlight movement as well. I never thought of coming up with a way to analyze it like you have done here, perhaps because I am not too familiar with grasshopper! I sort of try to guess the highlight movement and tactility from the curvature comb itself.
Hi Tony. I could not really tell much difference between the corner variations using the zebra (fairly obvious differences using curvature graphs though). I wonder if I can use Grasshopper to flatten out a curvature graph, if that makes sense? So you can see the true nature of the acceleration without it being transformed by the actual curve geometry.
Well, unrolling a curvature graph was pretty straight forward. I've also built a 'proof' of my construction on the original curve and it matches the Grasshopper curvature graph. I'll make a vid at some point.
Great stuff - I've filed your mac corners away to come back to as and when i get around to trying SW - Cademy XYZ I recall has something similar as a tutorial (free) meantime I continue my love hate with Alias
love to see your Grasshopper session, thank you so much!
all good, thanks for the comment!
Very interesting way of analysing change of curvature, thanks for sharing!
All good, thanks for the comment!

Is that the corner using a looped or iterative solver in Grasshopper? All the best with Alias!
