Uses OpenGL to render a spinning cube in a Looking Glass 3D display
This is a total hack - I'm still learning Rust, haven't used OpenGL in a decade, and am just tinkering around with a Looking Glass. It would be great if someone more knowledgable with OpenGL or Rust could let me know about any issues with this code - either file an issue here, submit a PR, drop me an email...
To run, you'll probably want cargo installed (via rustup). Then, clone and cd in to this repo, do cargo run.
The basic idea is that the 3D scene is created once, loaded in to GPU memory, then rendered 45 times in to "layers" of a 2D texture array from slightly different perspectives. Then, a fullscreen rectangle is drawn using a fragment shader that interleaves those 45 views on to the screen as appropriate for the connected Looking Glass.
