Hi Deepa, This is sort of a half-baked idea, but if you could get the positions of a bunch of center points, maybe you could add lines between them and use that as a sort of extrude profile for whatever shape you want to use.
You can base a mesh off of a picture's colour, so maybe that's a good way to get some centerline points. There is a picture example here that might be helpful http://geuz.org/photos/cg/cg.geo Sincerely, Max On Mon, Jan 6, 2020 at 1:06 AM Deepa <[email protected]> wrote: > Hi Max, > Thanks a lot for the response.
