This is the third image to 3D AI I've tested, and in all cases the examples they give look like 2D renders of 3D models already. My tests were with cel-shaded images (cartoony, not with realistic lighting) and the model outputs something very flat but with very bad topology, which is worse than starting with a low poly or extruding the drawing. I suspect it is unable to give decent results without accurate shadows from which the normal vectors could be recomputed and thus lacks any 'understanding' of what the structure would be from the lines and forms. In any case it would be cool if they specified the set of inputs that is expected to give decent results.

It might not just be your tests. All of my tests of img2mesh technologies have produced poor results, even when using images that are very similar to the ones featured in their demo. I’ve never got fidelity like what they’ve shown. I’ll give this a whirl and see if it performs better.

  All right, I was hesitating to try shading some images to see if that improves the quality. It's probably still too early.

  Tried it with a collection of images, and in my opinion it performs -worse- than earlier releases. It is however fast.

What stuck out to me from this release was this: > Optional quad or triangle remeshing (adding only 100-200ms to processing time) But it seems to have been optional. Did you try it with that turned on? I'd be very interested in those results, as I had the same experience as you, the models don't generate good enough meshes, so was hoping this one would be a bit better at that. Edit: I just tried it out myself on their Huggingface demo and even with the predefined images they have there, the mesh output is just not good enough. https://i.imgur.com/e6voLi6.png https://i.imgur.com/e6voLi6.png
