cam3

GLB on your webcam. Virtual camera out to Meet and Zoom.

---

Run it (30 seconds)

git clone https://github.com/aadi-joshi/cam3.git
cd cam3

OS	Command
Windows	Double-click run.bat or .\run.bat in PowerShell
macOS / Linux	chmod +x run.sh && ./run.sh

First run creates .venv and installs deps. Tray icon appears. Left-click for transform controls.

Before that (once per machine):

OS	Virtual camera
Windows / macOS	Install OBS. Start Virtual Camera, stop, quit OBS.
Linux	./scripts/setup-linux-vcam.sh

In Meet or Zoom, select the virtual camera (OBS Virtual Camera or the cam3 loopback device), not your normal webcam.
