Meta has shared a brand new analysis paper a few generative synthetic intelligence (AI) mannequin that may generate 3D property. Dubbed Meta 3D Gen, the AI mannequin generates high-quality 3D fashions from textual content prompts in lower than a minute. The corporate highlighted that the AI mannequin might create end-to-end high-resolution textures and materials maps utilizing a mix of texture technology and text-to-mesh methods fully developed in-house. Notably, this method is completely different from those by Tencent and Stability AI, which released image-to-3D fashions.

Sharing its analysis paper, which is at the moment hosted on Meta’s web site, the corporate claimed that its 3D Gen mannequin can render 3D fashions with excessive immediate constancy and making certain top quality. The mannequin can also be stated to assist bodily primarily based rendering (PBR), which permits the generated fashions to be relighted in numerous real-world functions. Notably, the analysis paper shouldn’t be peer verified, so a number of the claims made could possibly be exaggerated. There isn’t any option to discover out except the mannequin is launched to the general public.

The paper additionally explains the approaches used to develop the AI mannequin. Meta has developed two in-house techniques — Meta 3D AssetGen and Meta 3D TextureGen. AssetGen is chargeable for producing 3D objects from a given textual content immediate. In Stage I, it renders the 3D mannequin utilizing its understanding of the immediate, and in Stage II it additional refines the 3D mannequin to reconcile the view-based textures and completes these components that aren’t seen in any views. TextureGen is chargeable for discovering and making use of the appropriate textures on the mannequin.

This technique of 3D mannequin technology has a number of advantages for the generated 3D property. As an example, as a result of it makes use of textual content prompts, there isn’t a requirement for reference pictures and customers can generate fully distinctive fashions. The PBR assist additionally implies that these fashions may be taken out of the system and straight utilized to different environments. The paper claims the technology output of those fashions are additionally sensible.

Meta stated that the 3D Gen AI mannequin has a win charge of 68 % in single stage, which implies that 68 instances out of 100, the AI can generate the appropriate 3D asset primarily based on the textual content immediate. The corporate additional claims that the mannequin outperforms numerous business baselines by way of immediate constancy and visible high quality for advanced prompts.
