I made an i-Glasses emulator for WebXR over at https://sgeo.github.io/iglasses/ (showcasing Magic Carpet at https://sgeo.github.io/iglasses/magiccarpet.htm. I'll do the Descent II demo sometime soon).

For the first page, use grid.exe then press S to activate stereoscopic mode in the game.

It's currently unstable as I still need to actually handle WebGL context loss properly, as well as a lot of code cleanup.

The i-Glasses SDK tells developers to average out the incoming head tracking values. The antifilter is supposed to compensate for that, but it looks like Descent II does something different with its filtering.

i-Glasses are fairly easy to emulate because its head tracking data is exposed through a simple protocol over the serial port, which I was able to hijack for this network-enabled Emscripten DOSBox.

Forte VFX-1 emulation would be much better, as I believe applications can tell the headset to enable/disable stereo mode, and maybe the SDK doesn't say to do silly things, but I don't understand... any of it.
