nuclear@1 4 Filename : OVR_Profile.cpp
nuclear@1 5 Content : Structs and functions for loading and storing device profile settings
nuclear@1 6 Created : February 14, 2013
nuclear@1 7 Notes :
nuclear@1 8
nuclear@1 9 Profiles are used to store per-user settings that can be transferred and used
nuclear@1 10 across multiple applications. For example, player IPD can be configured once
nuclear@1 11 and reused for a unified experience across games. Configuration and saving of profiles
nuclear@1 12 can be accomplished in game via the Profile API or by the official Oculus Configuration
nuclear@1 13 Utility.
