I am looking for a way to convert an image into a flat-shaded polygonal mesh. This consists of two steps:
- Creating the mesh (manually), overlaying an existing image.
- Shading the mesh (automatically) automatically according to the colors contained within the image.
This should give a look similar to a flat-shaded low-poly 3D rendering. The result would preferably be a vector graphic (prerferably Illustrator, but Inkscape would do, too)
Question: How do I best create the mesh, allowing for additional manipulation later on, and is it possible to automatically shade it?
A workflow like for creating gradient meshes would be fine (except that I do want only polygons and no gradients).
I hope to achieve a look similar to what is shown in the lower right of this image:
Most likely just taking the average pixel value below a polygon is what would give me the desired effect after the mesh has been created.
