The system enables users to generate 3D models from text prompts in 1-2 mins.

The process consists of two stages: text-to-image and image-to-3D modeling. Point-E generates from text a low-resolution point cloud – a set of points in space.

A team of researchers at San Francisco-based OpenAI describe the process:

"Our method first generates a single synthetic view using a text-to-image diffusion model, and then produces a 3D point cloud using a second diffusion model which conditions on the generated image."

The 3D point cloud generated by Point-E differs from an image in traditional sense. But point cloud form let the modeling process be quick and easy.

The developers explain:

"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."

The process takes one to two minutes and requires no special skills. The 3D point cloud model generated by Point-E could be considered as an intermediate model in, for example, gaming, animation or 3D printing.

The team conclude:

"We refer to our system as Point·E, since it generates point clouds efficiently."

The system has open access; you may find it on GitHub.

Earlier in December launched Open AI a chatbot ChatGPT powered with a large language model that uses deep learning to produce human-like text. ChatGPT generates essays and solve math tasks.
