Proof of concept for real-time point cloud visualisations of Garry's Mod maps. Still extremely work-in-progress, but the core concepts are there and it's working well enough!
Copy the gmod_pointcloud_scanner directory into your Garry's Mod addons folder. The Pointcloud scanner weapon can then be found in the spawnmenu.
When you load into a game, you will need to specify the callback URL for the scanner to function.
pointcloud_url "http://pointcloud.example.com"Note that Garry's Mod cannot send HTTP requests to a local network addresses. If you're running this server locally, you'll probably want to expose this publically. I recommend localtunnel.
The webserver is a simple Express application. Run node server.js. By default, it listens on port 3000.
The webserver can also be run with Docker, if you're into that:
cd webserver
docker build . rafraser/pointcloud-server
docker run -p 3000:3000 rafraser/pointcloud-server
