Hi Matt
k1 is the maximum principal curvature. See Chen & Schmidt equation (6).

Hi,

I am very happy to find for the first time curvature estimation works on triangular meshes on matlab. Therefore I am very interested in the corrected version of the file.

Let me know when you have such a version, or, do you know an other file doing the same job than yours without this little bug?

Cheers
Yvus

Works well, however, I routinely get a "divide by zero" warning at line 65, even when using a hyperbolic paraboloid:
[x,y]=meshgrid(-3:.25:3,-3:.25:3);
tri=delaunay(x,y);
z=0.25*x.^2-0.25*y.^2;

Also, is please be more specific in defining output of which is minimum/maximum curvature, k1 or k2. Thanks!

Thanks for your codes.

trinormal is not included in the distribution!?
