scripts default iconPatch Curvature (Scripts) Publisher's description

This function calculates the principal curvature directions and values
of a triangulated mesh.

This function calculates the principal curvature directions and values
of a triangulated mesh.

The function first rotates the data so the normal of the current
vertex becomes [-1 0 0], so we can describe the data by XY instead of
Secondly it fits a least-squares quadratic patch to the local
neighborhood of a vertex "f(x,y) = ax^2 + by^2 + cxy + dx + ey + f".
Then the eigenvectors and eigenvalues of the hessian are used to
calculate the principal, mean and gaussian curvature.


FV : A triangulated mesh (see Patch)
usethird : Use third order neighbour vertices for the curvature
fit, making it smoother but less local. true/ false (default)

Cmean : Mean Curvature
Cgaussian : Gaussian Curvature
Dir1 : XYZ Direction of first Principal component
Dir2 : XYZ Direction of second Principal component
Lambda1 : value of first Principal component
Lambda2 : value of second Principal component

System Requirements:

MATLAB 7.12 (2011a)
Program Release Status: New Release
Program Install Support: Install and Uninstall
