Point-E Doesn’t generate 3D models in the traditional sense. Instead of generating robust and 3D-ready 3D models, it generates point clouds which are data points in a space that represent a 3D shape. Point-E is made of 2 model types: text-to-image and image-to-3D. In order to produce a 3D object from a text prompt, Point-E will sample an image using the text-to-image model.

Their team acknowledges the products limitations but believes it has a role in technical generative AI, “While our method still falls short of the state-of-the-art in terms of sample quality, it is one to two orders of magnitude faster to sample from, offering a practical trade-off for some use cases,” according to this AI Business article.

The OpenAI research team released the point cloud diffusion models and evaluation code on Github here. echo3D (www.echo3D.com; Techstars 19) is a cloud platform for 3D asset management that provides tools and cloud infrastructure to help developers quickly build and deploy 3D/AR/VR games, apps, and content.
