Oculus SDK for OS X 0.5.0.1-beta

Development Status

Our development for OS X and Linux has been paused in order to focus on delivering a high quality consumer-level VR experience at launch across hardware, software, and content on Windows. We want to get back to development for OS X and Linux but we don’t have a timeline. For more information, see Powering the Rift on the Oculus Blog.

The last available version of this SDk is 0.5.0.1-beta, and it has not been updated since March 2015. Compatible with pre-CV1 versions only (e.g., DK2, DK1).

0.5.0.1-beta Overview

The Oculus SDK 0.5 has moved from static linking to a dynamic link library (DLL) model in which the DLL is installed by the Oculus runtime. Using a DLL offers several advantages:

  • It allows us to fix bugs and update implementation for new headset features after applications have been compiled and shipped.
  • It allows us to evolve the API without breaking applications through the use of side-by-side versioned DLLs.

New Features

  • Updated LibOVR to rely on a runtime-installed DLL for better forward compatibility and delivery of bug fixes.
  • Introduced a four-digit runtime versioning scheme: PRODUCT#.MAJOR.MINOR.PATCH (e.g. 0.5.0.1). The last three digits of the scheme map philosophically to Semantic Versioning .
  • Added OpenGL support to OculusRoomTiny.
  • Introduced OculusRoomTiny_Advanced, which supports more SDK features and toggles.
  • Improved DK2 headset USB sleep management on Windows 8.1.
  • Updated the Oculus Configuration Utility to display headset status and diagnostic messages. Users can now view firmware version and serial numbers by hovering over the device image.

API Changes

  • Moved and renamed LibOVR/Src/OVR_CAPI.h to LibOVR/Include/OVR_CAPI_0_5_0.h.
  • Some additional public headers such as OVR_Version.h have been moved to LibOVR/Include/.
  • Added ovrHmdCap_DebugDevice flag to indicate that device was created with ovrHmd_CreateDebug.
  • Renamed ovrDistortionCaps::ovrDistortionCap_ProfileNoTimewarpSpinWaits to ovrDistortionCap_ProfileNoSpinWaits.
  • Removed ovrDistortionCap_NoTimewarpJit as Timewarp delay is disabled by default. Use ovrDistortionCap_TimewarpJitDelay to enable it.
  • Removed ovrTrackingState::LastVisionProcessingTime and LastVisionFrameLatency.
  • ovr_Initialize now takes a params argument that provides log callback and other arguments. See the in-code documentation for details.
  • Added ovrQuatf playerTorsoMotion argument to ovrHmd_GetEyeTimewarpMatricesDebug.
  • Added ovr_TraceMessage, which can be used to send a message to the log.
  • Removed support for DX10.
  • Deprecated DX9 support, which will be removed in a future version of the SDK.
    • ovr_Initialize now can return false for additional reasons than previously.
    • No API functions may be called after ovr_Shutdown except ovr_Initialize.

Bug Fixes

  • Fixed a bug in which full persistence was inadvertently enabled due to device initialization races.
  • Fixed uncommon deadlocks in the runtime service.

Known Issues

  • Rotating the display through System Preferences requires a restart of the service.
