Using the A-Frame WebVR framework, this web based application allows users to create VR and AR webpages for whatever they want - teaching resources, visualization, sharing your 3d models in a very cool way, and much much more! The VR pages can be used with google cardboard, but also can be viewed in the browser and used with the steam vive and oculus rift (untested).
You can try it at aframe-tools.sourceforge.io
More features are planned to be added in the near future!
