This simple drawing tool allows users to draw in 3D space. We created it as a bootstrapping tool made to let us create drawings in webVR which could then be used in other webVR projects.

It works for the Vive VR headset in webVR chromium, with multiple controllers. Press the trigger to draw, dip the controllers into different color paint buckets to change color, and touch the size icons to change brush sizes.
