Modeling using UV coordinates (projecting new geometry)

Coding Python Support
1

Is there any script out there that would let the user project new vertices / edges onto the geometry using UV coordinates?

Specifically, I’m thinking about how to project repeating patterns over a surface in an easy and flexible way. If you could draw new vertices / edges in the UV layout (with grease pencil perhaps? a new mode?) and then have them projected into 3d space onto the mesh, that would be amazing for developing surface details on complex surface objects.

Any thoughts? Ideas? Any methods for achieving this with existing tools?

The precedent for this is something a bit like the Unroll command in Rhino, which flattens out the mesh faces and allows you to edit them / project new geometry.

There was one at http://www.blendpolis.de
uv2mesh.py
It “remeshes” the uv mapped mesh based on resolution defined grid.
It’s close what you’re looking for but practically with limited use.
Anyway it’s a good idea!

Cool, that looks neat! Thanks for the tip.

What about meshmixer?

I cannot find the uv 2 mesh script
can you give direct link for it

thanks

Bsurfaces let’s you add geometry based on grease pencil strokes, maybe useful too.

Knife project has its uses too, but will only cut the mesh you project on.

A displacement modifier can help to add variation, with a small, tiling texture, it should be easy to create visible patterns.

Couldn’t find uv2mesh on blendpolis either, nor in meta-androcto’s addon repo.
