Hello,
I am facing a problem when computing curvatures of a 3D contour in paraview. It seems that paraview does not generate smooth enough coutours to compute pertinent curvatures of the surface. A picture S50.jpg and a source data file S50.vtk is attached to this post to illustrate the problem... For information, the contour test sample is a discrete sphere of radius R=1 (C=1/R+1/R=2). It is generated from a 3D field using the contour filter... Does someone have an idea how to improve the calculation of curvature? Does it come from a bad discretization of the contour or does it come from a non-accurate algorythm of the curvature filter? Have a nice day, Eric |
