Tilt Brush Backyard – Mixed-Reality VR Painting in Nature with HTC Vive

I’ve been thinking for a while about taking the Vive outside to test how it handles Nature. The object-tracing capabilities of Tilt Brush have already been pretty well established. SUTU and I had planned to take the VR rig outside last week, but it ended up raining, so I had to do it by myself after he left :|

The process was great fun! Outside Vive is a super strange feeling, but it worked well. Even climbing a ladder while blind was quite fun. (Note: Don’t take your Vive outside at daytime, tracking won’t work and sunlight through the lenses can burn the screens.)

I took a couple of precautions, most important was applying some tape to the controller so it didn’t get scratched up by the brutal nature in my suburban backyard. I figured out last week that the most accurate way to “trace” objects in Tilt Brush is to use the back of the controller, as the “stylus point” is at the top of the handle, not the tip of the tracking ring.

I’m still experimenting with mixed-reality motion-control shots. This version I stabilised the Tilt Brush feed in After Effects as it had a constant slow oscillation which I think may be to due to vibrations from my robot’s stepper motors.




Tilt Brush Pendulum Test 01

While investigating tracking precision for motion control timelapse filming in VR I had a thought, and then sidetracked myself for half a day designing various Tilt Brush/Vive pendulum rigs. The first one is very simple, but worked beautifully:


If you have Tilt Brush, I’ve made the sketch available for your delectation [Dropbox link – 1.94MB]. It’s a lovely place to spend some time.
