Surface mesh and pointNeighbors.pointPosition: Possible?

[Pancho]

I don't have any luck to smooth a surface mesh by getting the position of the neighbors and then interpolate them. As soon as I plug in the point position it turns red.

self.pointNeighbors. -> pointPosition (not possible)

Can anybody confirm that and is there way way to smooth a surface mesh from within ICE? After all I can get and set point positions. With polygon meshes this is no problem at all.

Cheers!

P.S.: Parts of the surface mesh need to follow another geometry by repeating a set of get closest location on geometry and smooth functions in ICE I usually achieve what I am after. But with the nurb mesh it seems to be a bit tricky.

P.P.S.: Do surface meshes have vertex IDs? Couldn't get any as far as I can remember. Only the uv values.

Try the compound and script on this vimeo from Emilio Hernandez.

BTW, NURBS have control points and knots. If you need to smooth the Mesh you need to work on the contol points or knots and move them arounds. I don't know if you can access these elements within ICE.

Hi DAniel,

thanks for all the input! I have my own compounds for smoothing and relaxing and they work quite nicely. I also managed to transfer a surface grid into a sphere. So setting and getting point positions is no problem. But unfortunately I don't the the pointNeighbors in ICE to work with this kind of mesh. With polys, no problem, but the nurb thing bothers me. probably a polymesh with the same size and form could work as a reference for the nurb mesh. ONly solution which comes to my mind right now.

Thanks!!!
