Varjo SDK for Custom Engines

Varjo SDK for Custom Engines, release version 2.1.0

December 16, 2019

Added

  • New error codes varjo_Error_ValidationFailure, varjo_Error_InvalidSwapChainRect and varjo_Error_ViewDepthExtensionValidationFailure. These tie with the added validation for varjo_SubmitInfoLayers.
  • Benchmark example app commandline parameter –depth-format for setting the depth-stencil texture format (d32|d24s8|d32s8)
  • View extension (varjo_ViewExtensionDepthTestRange) to define ranges for which the depth test is active. Outside the given range the layer is alpha-blended in layer order without depth testing.
  • varjo_UpdateNearFarPlanes to replace deprecated varjo_UpdateClipPlaneDistances. The implementation of this function is in Varjo_math.h.

Changed

  • Improve MRExample application
  • Update Benchmark to use varjo_UpdateNearFarPlanes

Deprecated

  • Legacy rendering API. This includes types in Varjo_types.h and functions in Varjo.h, Varjo_d3d11.h and Varjo_gl.h. All applications need to migrate to Layer API (defined in Varjo_layers.h).

 

Varjo SDK for Custom Engines, release version 2.0.0

November 7, 2019

Added 

  • Mixed reality API (Varjo_mr.h and Varjo_mr_types.h) for controlling mixed reality devices and cameras 
  • Mixed reality API related events: 
    • varjo_EventType_MRDeviceStatus 
    • varjo_EventType_MRCameraPropertyChange 
  • Mixed reality API related error codes: 
    • varjo_Error_RequestFailed
    • varjo_Error_OperationFailed 
    • varjo_Error_NotAvailable 
    • varjo_Error_CapabilityNotAvailable 
    • varjo_Error_CameraAlreadyLocked 
    • varjo_Error_CameraNotLocked 
    • varjo_Error_CameraInvalidPropertyType 
    • varjo_Error_CameraInvalidPropertyValue 
    • varjo_Error_CameraInvalidPropertyMode 
  • Property key for querying whether a mixed reality capable device is currently connected (varjo_PropertyKey_MRAvailable)
  • Data stream API (Varjo_datastream.h and Varjo_datastream_types.h) for subscribing to color camera and lighting cubemap streams 
  • Data stream API related events: 
    • varjo_EventType_DataStreamStart 
    • varjo_EventType_DataStreamStop 
  • Data stream API related error codes: 
    • varjo_Error_DataStreamInvalidCallback 
    • varjo_Error_DataStreamInvalidId 
    • varjo_Error_DataStreamAlreadyInUse 
    • varjo_Error_DataStreamNotInUse 
    • varjo_Error_DataStreamBufferInvalidId 
    • varjo_Error_DataStreamBufferAlreadyLocked 
    • varjo_Error_DataStreamBufferNotLocked 
    • varjo_Error_DataStreamFrameExpired 
    • varjo_Error_DataStreamDataNotAvailable 
  • varjo_BeginFrameWithLayers to begin a frame when using the layer rendering API. This is effectively the same varjo_BeginFrame but without the second parameter. 
  • New parameters for controlling gaze output filter 
  • Mixed reality example (MRExample) 
  • New options for the benchmark example to run with video see-through 

 Removed 

  • Flag varjo_LayerFlag_BlendMode_Inherit. Inheriting has no effect anymore since runtime version 2.0, so the flag is obsolete. 
  • Flag varjo_LayerFlag_BlendMode_Opaque. Opaque is the default blending mode since runtime version 2.0, so the flag is obsolete. Applications utilizing alpha blending need to turn it on using varjo_LayerFlag_BlendMode_AlphaBlend. 

Changed 

  • varjo_LayerMultiProj::views can be filled with just two views for submission of a stereo pair. Varjo compositor will split the image for the quad display devices. This is a runtime change, but important enough to be documented here as well. 
  • Rename varjo_LayerFlag_DepthSorting to varjo_LayerFlag_DepthTesting. 
  • Examples are now built using CMake. Instructions under examples/README.txt. 

Deprecated 

  • Blending / depth testing related submission flags (varjo_SubmitFlag_Opaque, varjo_SubmitFlag_InvertAlpha and varjo_SubmitFlag_DepthSorting). Behavior is controlled now for each layer separately. 
  • varjo_SubmitInfoLayers::flags. This field has no effect.

 

Varjo SDK for Custom Engines, release version 1.4.0

October 3, 2019

Added experimental layer rendering API (Varjo_layers.h and Varjo_layer_types.h) Note: This will be finalized in the next release  and might still be subject to small changes. The supplied example uses both rendering APIs.  Developer documentation will be included in the next version as well
Added varjo_RequestGazeCalibrationWithParameters for application-controlled gaze calibration
Added varjo_GetViewCount to query number of views
Added varjo_Error_GazeInvalidParameter to denote error of passing invalid parameters to varjo_RequestGazeCalibrationWithParameters
Added varjo_Error_D3D11CreateTextureFailed to denote error in texture creation
Added properties for querying gaze calibration quality
Added property for querying HMD connection status
Added support for the new texture formats: A8_UNORM, YUV422, RGBA16_FLOAT, D24_UNORM_S8_UINT and D32_FLOAT_S8_UINT

 

Varjo SDK for Custom Engines, release version 1.3.0

June 19, 2019

Minor documentation improvements

 

Varjo SDK for Custom Engines, release version 1.2.0

April 18, 2019
Support for 32-bit applications
Improved examples
Native SDK projection matrix is now off-axis to provide improved image quality.
– NOTE: Applications that don’t support off-axis projection should call varjo_SetCenteredProjection(…) function to enable old behavior.
– NOTE: Applications built with <1.1 behave as previously.
Error messages for rendering and gaze are separated.
VarjoLib does not require CPU with AVX support anymore
