- 26. • VR augment or VR native? • Our opinion – VR First! • You must try it out to see what works • More resources in PDF
- 27. Design for: • Widest reach? • Potential Sales? • Studio Survival? Build for comfort / avoid motion-sickness
- 28. • Frame Rate is KING! • Dropped frames are not worth better graphics • “Toon” graphics are accepted by the brain • Optimize early and often • Avoid CPU spikes on complex math or physics • Reduce poly count and texture size • Every optimization has a benefit, no matter how marginal!
- 29. • Be close to the action and any UI • UI should fit in the players viewport • Pausing the game should allow user to look around still • Do sane things (i.e. fade the colors) if the user leaves tracking • Help them find their way back! Sound may help • Don’t rely on pure stereo parallax – add other cues • Keep your world self-contained – no gaps in geo
- 30. • Made With Unity! http://madewith.unity.com • VR forums (even one at forum.unity3d.com) • UploadVR, RoadToVR, reddit, other sites • Oculus Share, Steam • Have as many people try it as possible; conferences / expos • Join the community of VR developers. We love to share!
- 31. • Authoring VR in VR • HRTF still not ubiquitous – yet! • Apple and Google are worth watching, along with “little guys” • Impact of AR? (Hololens, Meta, Magic Leap)
- 32. • Deloitte says VR in 2016 will be the year for experimentation • Few buyers of games at first • Enterprise adoption will start • No time to waste! Get to it!
