It seems like a party trick which isn&amp;#x27;t very useful, and pretty much impossible to reconstruct the original object accurately.

If you have 50+ images, the tech from 10 years ago is already good enough to get Hollywood-quality 3D scans.&lt;p&gt;From what I understand, they use the text keywords detected from the image as guidance and they also apply a loss between the current diffusion state and the source image. In effect, this is stable diffusion for 3D shapes but with clever conditioning. That means this algorithm will also work just fine if you have 2+ input images.</text></comment>

Not to mention that solution approaches can often cross pollinate.&lt;p&gt;Research is additive not a zero sum thing.</text></comment>
