When it comes to technology hype, AI is overshadowing the metaverse to capture the attention of businesses and consumers everywhere.
But AI could further enhance the metaverse, at least in one sense: asset creation. AI has the potential to scale the creation of 3D assets for use in virtual environments.
AI Business explores the various AI 3D generation capabilities.
What is AI 3D generation?
AI 3D generation uses artificial intelligence to generate 3D models or objects.
There are several techniques:
Each technique can potentially help creators customize and generate virtual assets and environments at speed, especially helping those without prior 3D modeling expertise.
Potential applications of AI 3D generation are for creating assets in video games and metaverse environments, as well as design concepts for products in business. It could even be applied to creating virtual representations of factory floors, generating potential mock-ups of industrial plants.
Text-to-3D AI models
Creators: Google, UC Berkeley
First published: September 2022
DreamFusion can generate 3D models from text inputs. It is essentially an expanded version of Dream Fields, a generative 3D system Google unveiled back in 2021.
DreamFusion requires little to no prior training – meaning it can generate 3D representations of objects without 3D data. It uses 2D images of an object generated by the Imagen text-to-image diffusion model to understand different perspectives of the model it is trying to generate.

Named after the famous Spanish architect, Gaudi was created by researchers at Apple to generate 3D scenes from text prompts. Users can redraw the scene from any angle using natural language – allowing for the creation of interior scans of buildings.
GAUDI also can generate new camera movements through 3D indoor scenes via text, such as a user input to 'go through the corridor.'

MVDream is one of the newest models on this list. Researchers from ByteDance and the University of California, San Diego developed a diffusion model that can generate high-quality 3D renderings from text inputs.
MVDream can generate multiple views of the model that are geometrically consistent multi-view images.
The model can be fine-tuned for personalized 3D generation using tools like DreamBooth3D.

Magic 3D is a pre-trained text-to-image diffusion model. It can create quality 3D mesh models from text prompts.
Magic3D utilizes a two-stage process:
It creates a coarse model using a low-resolution diffusion.
The system then uses a sparse 3D hash grid structure that is further optimized with an efficient differentiable renderer to create the final output.
Magic3D can create high-quality 3D mesh models in 40 minutes.
