(Solved) 2D 3D-Model

Is there a way to convert a picture into a trimesh (z always 0)?

Something like this could be easily converted into a vector grafic, so it should be possible to create a triangular mesh from it

See - The simplest Blender model of all. Assuming you want the black part to be the visible part, just make the white part transparent.

Next I’ll assume that you want that black shape as a 3D model, instead of a plane. So what you do next is to put a series of single vertices (dots) around the outer edge of the shape. How, many? That depends on just how rounded you want it. Then connect them together as a new shape and discard the original plane. Finally, unless you want your new shape to be just a plane, you will need to extrude the shape. Now AFAIK, Neverblender should take care of making it into a trimesh.

This is well known, my signs in CCC use that trick. To bad, it doesn’t work on items. (There is another treat where I bring up that question)

How? Is there a process/function which does this automatically? This will be at least 100 dots (vertices).

Then connect them together as a new shape and discard the original plane.

Again: How? I take, there is no function which does it, at least not in Blender.

Finally, unless you want your new shape to be just a plane, you will need to extrude the shape.

The new shape is just a new node in the gurdy (I hope you already got it). The sound hole, which is present in most string instruments.

Sorry, no idea :innocent:. I had hoped someone who knew what to do would have chimed in already (even if only to say my suggestion was rubbish). ATM my only access to Blender is the portable version from PortableApps and actually doing most complex 3D is beyond my skill set (at least for now anyway). Having said that, the sound hole being that small wouldn’t it be better to add it to the texture anyway?

Very well. I finally found a piece of software which gives me the points of the outline of the shape and has a comfortable editor for final adjustments of the x and y coordinates. Exported this to SVG, recalculated the SVG-thingies with excel, added some faces. I ended up with this.

Job done, case closed.

That was Plan C. Sounds easy, but isn’t …

Thanks.
