Flying : Major accomplishments, and major lessons learned.

dSky VR : under the GGB!

dSky VR : under the GGB!

The good news : we got Flying Adventure working in the Rift, and let me tell you : flying under the Golden Gate Bridge, through volumetric clouds, at 70mph about 3′ above deck… a total rush. I flew in and around the city for about 30 minutes, totally absorbed, free, in bliss. Further, there was a palpably sublime moment when, flying across the surface of the water at speed, I looked down and saw something on the face of the waves: it was my avatar’s reflection, distorted in real time. Spine tingling.

whats that on the face of the water? me, as avatar

The bad news : humans and birds are not at all built the same. We first modelled the simulation so that a human flyer would be belly down, in a sort of yoga cobra position, abs engaged. The challenge is : while a birds eyes are on the *sides* of its head, and its head is naturally aligned for the bird to view forward while prone… a human’s eyes are on the *front* of our heads; and while prone, we are naturally looking downward. thus, if we are using “natural” forward propulsion, as one might imagine superman or ironman doing, we humans are forced to *seriously* arc our necks back in order to see “forward” towards where we are headed, and to more naturally navigate our flying world.

Human neck : natural downward articulation while flying | avian neck : natural forward orientation

human v. eagle : very different animals.

The consequence : after 30 minutes of flying, my neck really hurts… and that’s coming from a trained acrobat, supposedly used to such contortions.

Fast conclusion: we are fast coming full circle to Palmer Luckey’s assertion that “present-day VR is a seated experience”. Going to start exploring alternate methods of navigation metaphors, including:

  • levitating chair, a la Professor X
  • cockpit, a la an F-18
  • saddle riding, a la How to Train Your Dragon
quite possibly the best way to fly

quite possibly the best way to fly : on a saddle, atop a trained giant eagle.

  • we also might simply try rotating the camera 90° up
    relative to the avatar body :)

Until our next post, enjoy the screenshots.

Controllers, Controllerism, Controrgasm?

virtual xBox 360 controller - high fidelity modelMy god. I haven’t installed this many device drivers and intercept layers in… well, in my entire life. VR exploration and 3D creation require whole new methods of interacting with a universe, and tho the Apple Magic Mouse — essentially, a crazy-accurate optical mouse with a curved multi-touch surface fused to its carapace — is still my go-to interface after all these years, I find myself asking: What is the best interface for navigation and manipulation?

In the past month, I’ve configured my lovely MacBook Air LightWarrior(TM) to accept ALL the following input streams:

  • LeapMotion — “AirHands” pointing and gesture tracking
  • xBox360 wireless game controller — 8 buttons, 2 joysticks, 2 pressure sensitive triggers, 1 D-pad… all in the palm of your hand
  • 3Dconnexion 3d mouse — an amazing piece of kit that should be standard for all 3D design rigs.
  • Unity xTUIO iPad multi-touch simulator — enables one to use a bluetoothiPad to send multi-touch signals in real-time to the Unity application.

and, of course:

  • Oculus Rift Optical Head Tracking — explore the Multiverse simply by looking around, i.e. moving your torso, head, neck, and eyeballs. CAUTION: may cause a very bizarre form of RSI (repetitive strain injury), a.k.a. a VSN (Very Sore Neck)
