Hi all. I’m working with 2 other people with SubD over the last 2 years. Almost daily. What is the progress? Will we have curvature graph for SubD on V8? (this really should have been a 7.0 feature) (I can use history to see the curvature graphs of the edges of the SubD, but history doesn’t work…

There is another thread on the new Popup toolbar here. https://discourse.mcneel.com/t/resizing-pop-up-toolbar/147505/53

Mater artium necessitas [Rhino SubD curvature] … 90 rows of code (of which 40 are for the curvature radius > gradient color conversion) Only minimum curvature (but also I never understood when/how max/gaussian is used/needed). I made this in my today’s lunch break, I guess McNeel staf…

To me it looks static is that correct? I suppose you are making a ToNurbs in the background. I think the idea is to have a tool that works interactively while modifying the controlpoints, like it works now on surfaces. On heavy models constantly converting to Nurbs would mean a lot of computing.

The left one is interactive, no nurbs involved, only mesh. The SubD is referenced in a c# script that outputs a colored mesh… Subdivision level is 4, each face make 16x16 mesh faces… on heavy SubD smaller level is, indeed, needed. I’m making the ToNurbs conversion manually on rhino only to compare…

in that case: sweet :slight_smile: I take my words back

Just seen… great! It’s all or nothing, every edge or none … ok. Seen also you finally added SubD curvature analysis! [2023-05-24 08_58_51-Window] Woohoo!! :star_struck: Thank you guys!!

This is great! We’d love to see also a new mode added to the curvature analysis tool (for all object types): Three colors for concavity, convexity and planarity. What colors should they be? Extra credit: A projected dot pattern (with toggle visibility of course) for areas with double curvature…

[image] Gustavo Fontana: Three colors for concavity, convexity and planarity Depending on what you mean by concave / convex / planar, that might not cover the whole surface. Do you mean 3 colors for areas with: positive Gaussian curvature (“sphere-like”), negative Gaussian curvature (“prin…

I think 3 colors are good enough. Current problem is only gaussian mode is able to display negative values (green to blue). See the animated picture here: [image] Current curvature analysis tool can't distinguish concave vs convex! Rhino Hi all. Since some months I’m de…
