Dear developers,

I am trying to generate triangle meshes for cyllinder or cone type shapes so that I can save the data in unstructured grid format. Previously I did it for sphere using Tesellate filter.

Can someone suggest me a way to generate trigular cells( cell type 5)for cyllinder or cone where there is a circular cap in the ends?

Thanks

You mean can actually circular or does an approximation works for you ?

Tahnks for your reply. Yes an approximation will work. I want to generate the triangular cells for the curved surface as well as the circular base.

Use Triangulate filter.

Thanks, it works perfectly.
