Show HN: Text to 3D simulation on a map (does history pretty well) Simulate anything on a map from a text prompt -- and conduct risk analysis against LiveUA map's global realtime data points from social media and news sources. I trained a GPT-2-size model on historical incident data used to predict things that will go wrong. As historian Benjamin Breen mentions, the leading language models are good historians, so the application will simulate historical events pretty well also. I include a Multi-Agent RL Urban Mobility model in progress displayed on the map as small white cubes representing traffic and pedestrians. Around SF, it uses real census data and other sources for semantically meaningful day plans, etc. It will populate where you move the map, albeit a little slowly. This is based on previous work on my GitHub--I hope to connect it to Unreal's city samples project soon. The simulations are pretty simple so far but will grow in complexity soon. I won the AGI House World Models Hackathon with this and the MARL model. Many thanks to Shota Matsuda and Garrett Johnson for the cloud and atmospheric effects libraries on Github at takram-design-engineering/three-geospatial Glad for feedback, and thanks for trying it out! https://mused.com/map/ May 20, 2025 at 01:43AM
