<div dir="ltr">The is an artefact where the tube forming the surface is joined. The torus is formed by taking a plane wrapping it into a cylinder and then joining the ends of the cylinder. So there can be discontinuities where the edges of the plane butt together. You could experiment with changing the parameters in vtkParametricFunction and/or vtkParametricFunctionSource (change resolution here).<div>

Subject: Re: [vtkusers] Problem with "Compute Gaussian, Mean, Minm and Max Curvatures" example<br>Hey Bill.<br>
<br>
With your provided code i get the expected result. Thank you!<br>
<br>
I still get an artefact, which you can see in the following image:<br>

(I created this image with Bill's provided code)<br>
<br>
Does someone knows how i can avoid it?<br>
<br>
@ Jott: Thank you for your help.<br>
