OpenAI has introduced Point-E, a new system capable of generating 3D point clouds from text prompts significantly faster than previous methods. Unlike other approaches that take hours, Point-E can produce a 3D model in just one to two minutes using a single GPU. The system first creates a synthetic image from the text prompt using a diffusion model, then generates the 3D point cloud based on that image with a second diffusion model. While the quality may not yet match the absolute state-of-the-art, its speed offers a practical advantage for certain applications, and OpenAI has released the pre-trained models. AI
