Hi Alex, thanks for the question! Currently, we are not producing great results when it comes to realistic humans, animals, and vegetation. Those requests are not served as we haven't yet trained for these kind of inputs. Once our geometry reconstruction has high accuracy for hard-surface objects we'll move on to this category, collect data, train and improve.

> Once our geometry reconstruction has high accuracy for hard-surface objects we'll move on to this category, collect data, train and improve. is that really possible though? For complex objects there should be multitude of 3d structure that fit a 2d projection and there's really no way to say "which one is the most correct one".

Thanks ekianjo! Yes, that is true. For complex objects, the effect of the algorithm is to lose detail. We mitigate this with our multi-view option (up to 6 images of different views). At the moment high level of complexity is in most cases not processed. We do best with simple objects.

Can we see more examples? (Including some less successful ones and some failure cases ideally)

Yup, would love to see more examples how this works!

Thanks both! Here is a video demonstrating the web app version, with 3 more examples (one sketch, one concept art, one photo): https://youtu.be/jSZ7RMq5EKA Let me know what you think!

Can this convert a 2d floorplan in DWG format into a 3d model?

Thanks for the question! Currently DWG is not a viable input. We once tried it with a photo of a maze-like floor plan and it just created the “walls” if you like.

Is that AI-based, e.g. like https://www.arxiv-vanity.com/papers/1511.06702/ ? BTW, great job improving over the public state of the art.

Thanks for the comment and kind words! Indeed it is!

> Transform your 2D art into 3D Content One suggestion: The example on your home page, to me, looks fairly three-dimensional (as far as 2D sketches go), with shading and everything. I would suggest a better example might help with capturing potential customers. Looks great though

Thanks a lot for the feedback and suggestion! Taking it onboard!

That could be interesting. Anyway I could try?

Can this be used to generate 3D print files? (stl)

Thanks Peter! Yes, we can add this download format as well (we currently have obj, fbx, glb, gltf)

Thank you!

From the video I gather that texturing is still a manual step? I'm a little confused how your editor showed the model without a texture, then you were able to do a perfect color fill on the different parts of the model. One of the most difficult parts of modeling is the texturing, (bump/normal map, albedo/lighting, color, etc) with lots of trade offs for how big your texture is, how much can be re-used, not to mentio…

Thanks for the comment! Yes, texturing is a manual step using a small widget we've built. We do the fill monochrome for the different parts of the model. It's easy to do because of how the model is generated formed by different parts. Then, as it enters the game environment, it's affected by lighting too.

Yes, that is correct in the majority. The focus is games/apps with high volume, low detail. However, we can also do higher detail/resolution and some of our customers are PC and console studios and they use it for prototyping, blocking out scenes, iteration.

Our website and this video feature some higher detail models: https://youtu.be/jSZ7RMq5EKA
