Here is my next build trying to push subd harder- Focus was on sharp/soft, and detail- built the same way as the 907 Amazing how fast these come together! Main model took about 8 hours, then I picked at it for a few days adding details and render set ups. rendered using decals, and standalone cy…

very cool! this gives me an idea… [capture_gf_081643PM_200427] what about a way to add edge loops to CurvatureGraph? so you can see the inflections in curvature and the bumpy areas? @dalelear , how would that Curvature Graph look like? Do you base it off a degree-3 nurbs curve based on the loop v…

Hi Kyle, great work! It would be cool to see some wireframe images and some zebra/reflection maps too.

[image] gustojunk: @dalelear , how would that Curvature Graph look like? Do you base it off a degree-3 nurbs curve based on the loop vertices as control points? of do you have a more mathematically pure way to extract that info? The brep created by ToNurbs is identical to the SubD surface with…

Nice, so I think I can get to see live curvature graphs on SubD, but for all the edges at once. I can explore more later to see if I can isolate selected loops only. But when I edit the SubD (moving points) the SubDEdges extraction component breaks. [capture_gf_100058PM_200428] [capture_gf_100144P…

That might be so, but it would be immensely helpful to have feedback of curvature during sub-D modeling, don’t you think?

Great work Kyle, Rhino 7 will be a huge step forward :slight_smile: Cheers Joao

[image] theoutside: (hitting the render button as opposed to raytraced mode) Is there any performance difference between raytraced mode and standalone cycles?

[image] norbert_geelen: That might be so, but it would be immensely helpful to have feedback of curvature during sub-D modeling, don’t you think? Yes, I think this is important and it’s on the list of things to do https://mcneel.myjetbrains.com/youtrack/issue/RH-58162 It will most likely app…

standalone is slightly faster because it does not have the interactive element of raytrace mode, but it is the same render engine underneath.
