So far it&#x27;s only been used to train a scene from photographs from multiple angles and rebuild it volumetrically by adjusting densities in a point-cloud. But it might be possible to train a model on multiple different scenes, and perform diffusion on a random point cloud to generate new scenes. Rendering a point cloud in real time is also very efficient, so it could be used to create insanely realistic game worlds instead of polygonal geometry. It seems someone already thought of that: https://ar5iv.labs.arxiv.org/html/2311.11221</p><p><a href="https://hackerpaper.kaipfister.de/p/2311.11221/">Paper and discussion history</a>.
