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!

| Random thing worth I ran into once, you may have already
| handled this but sharing just in case:
|
| May want to confirm the map renderer is making its requests
| using the URL with both the session and API key instead of
| only the API key. If your API requests are base key only,
| every refresh client-side might be unexpectedly consuming one
| of your root quota units, rather than each user getting a
| session of unlimited tile loads for 3 hours. If you're seeing
| network traffic in the console from your renderer out to the
| API without the session token in the query string along with
| the API token, or if you see the session token is totally
| different after refreshing, that might be a sign of something
| wonky causing quota depletion.
|
| Example URL for a tile fetch with both params:
| https://tile.googleapis.com/v1/3dtiles/datasets/CgA/files/UlR
| PVEYuYnVs.json?session=SESSION_TOKEN&key=YOUR_API_KEY
|
| Examples:
| https://developers.google.com/maps/documentation/tile/create-
| renderer#requests-and-responses
|
| A quick check would be to see how far apart your google
| analytics for unique users are vs. your API console usage
| data. If way less than 10,000 unique users depleted the
| 10,000 unit quota it may be another indicator of something in
| token/session setup.
