Gaussian curvature analysis - sphere appears to change in curvature


#1

Why does it show changes in curvature when a sphere inherently has continuous curvature throughout?

Hi Ariel - the false color display works off of a mesh that is created from the surface - there is always a slight discrepancy - the best policy, I think, is tyo make sure the analysis mesh is very accurate - poke ‘Adjust mesh’ and set the detailed controls to a lot - like 5000, ‘Minimum initial grid quads’ then you can pretty much zero out the rest of the controls.

Hi Pascal,

I’m still getting the blue shading:

Hi Ariel - yeah - you see that it’s in the last triangles at the pole? - if you make the polygons still smaller, that blue area will shrink accordingly but it may never be gone.
