I managed to integrate vtk.js so this plugin can work for my meta quest 2 VR headset. It works pretty well, but there is some fine tuning needed plus I was controlling with the vr handset and not head motions. I also had to play it in a "windowed" mode, so it is not fully immersive. I will reach out to your discord server once done. I intercepted the 3d map rendered meshes and interfaced the meshes to the vtk.js variables. It distorts angles slightly, but it works decently. It follows the OpenXR spec.
