The Unity3D game authoring engine is available on the PlayStation 4 alongside Morpheus development tools. The first thing to note is that the PlayStation tools are for Windows operating systems only. I had to get creative as a Mac user to accommodate this requirement.
The PlayStation 4 has potentially the best current input methods available for VR. The PlayStation 4 Camera does an amazing job tracking the PlayStation Move controllers and the Dual Shock 4. This makes prop manipulation in VR effortless for the player, without any odd latency or offset compensation. The PS4 camera is also capable of skeletal tracking, but I wouldnt recommend walking around wearing a VR headset to anyone (yet).
Developing for the PlayStation 4 is straightforward for anyone who knows how to use Unity3D. The key differences are that some shaders need to be ported and that a build/run is needed to run on the PS4 devkit.
Like Oculus, Morpheus tools are still in development so some modification to the available scripts may be needed to best suit your project. I needed access to the stereo cameras in the scene Hierarchy, which is the default behavior in Unity3D. The Morpheus toolkit generates the stereo cameras at runtime (on the fly) so I had to adjust the script to have the SDK use my cameras instead of making new ones. The script was easy to follow and well commented so this took very little time.
The other key difference is that headtracking is done on the parent object of the cameras (rotation/position). Oculus applies most of the transform data directly to the right camera and has the left camera follow with an offset. This difference required me to adjust my game to pay more attention to the parent tracker instead of the individual cameraseasy to do once youve figured it out.
One of the things that surprised me most was how fast I was able to get up and running with good performance. Vanguard V was migrated to PS4 and playable within one day! The PS4 is also very good at giving you feedback on performance issues and script debugging... ...I had the Vanguard V demo running at 70-120fps after just a few days of work.
