Function Documentation

◆ varjo_Lock()

varjo_Bool varjo_Lock	(	struct varjo_Session *	session,
		varjo_LockType	lockType
	)

Try to lock the given lock type.

Client must successfully acquire lock before any calls to features behind the lock.

varjo_Unlock must be called after the feature is not needed anymore and it is free to be used by other clients.

Each lock type can be locked by one application at a time. Lock call returns varjo_True if the calling client holds the lock after the call. If the lock was held by the calling client already, varjo_Error_AlreadyLocked error is set. Return value is varjo_False if another client is holding the lock.

Note: Application needs to hold the lock as long it is going to use the feature.

Possible errors: varjo_Error_OperationFailed, varjo_Error_NotAvailable, varjo_Error_CapabilityNotAvailable, varjo_Error_AlreadyLocked

Parameters

session	Varjo session handle.
lockType	Lock type to be locked.

Returns: varjo_True if the client holds the lock after the call, otherwise varjo_False.

Parameters

session	Varjo session handle.
prop	Camera property type.
modes	Fills this array with the possible property modes.
maxSize	Maximum amount of modes that fit into 'modes'. Should be >= varjo_MRGetCameraPropertyModeCount().

◆ varjo_MRGetCameraPropertyValue()

struct varjo_CameraPropertyValue varjo_MRGetCameraPropertyValue	(	struct varjo_Session *	session,
		varjo_CameraPropertyType	type
	)

Returns the latest manual property value set with varjo_MRSetCameraPropertyValue for the given property type.

◆ varjo_MRGetCameraPropertyValueCount()

int32_t varjo_MRGetCameraPropertyValueCount	(	struct varjo_Session *	session,
		varjo_CameraPropertyType	prop
	)

◆ varjo_MRGetCameraPropertyValues()

void varjo_MRGetCameraPropertyValues	(	struct varjo_Session *	session,
		varjo_CameraPropertyType	prop,
		struct varjo_CameraPropertyValue *	values,
		int32_t	maxSize
	)

Get possible manual property values.

The needed size for the 'values' output parameter can be obtained by calling GetCameraPropertyValueCount.

Values have different meaning depending on the property.

ExposureTime: Floating point frames per second. e.g. 90.0 -> ~11ms exposure time.
ISOValue: Integer ISO values. e.g. "200" -> ISO200.
WhiteBalance: Integer color temperatures in Kelvin.
FlickerCompensation: Integer in Hz. e.g "50" -> compensation for 50 Hz. This is useful when using the HMD indoors with mostly artificial light bulbs, which flicker at the frequency of 50Hz or 60Hz and can cause visual flicker artifacts on the video pass through image. The correct setting depends on the underlying power grid's frequency. e.g. In most parts of Africa/Asia/Australia/Europe the frequency is 50 Hz and in most parts of North and South America 60 Hz.
Sharpness: Integer denoting the power of the sharpness filter. The lowest value corresponds to small amount of filtering and the highest value corresponds to the largest amount of filtering.
Eye reprojection: There is a physical offset between the user's eyes and the video pass through cameras, which can cause the perception of the real world to feel different than without the HMD. When the eye reprojection is turned on, the software reprojects the video pass through image from the physical camera position into the physical position of the user's eyes. While this will improve the perception it can also cause visual artifacts and therefore can be unwanted behavior for some applications. This property offers two different reprojection modes:
- When mode is AUTO, the view is automatically reprojected based on the depth map. This is the most physically accurate reprojection.
- When mode is MANUAL, the view is reprojected into a certain static distance. Value is a float specifying the reprojection distance in meters.
Auto exposure behavior: Controls how video pass through reacts to lighting and environment changes when auto exposure is in use. Doesn't have any effect if both ExposureTime and ISOValue are in manual mode. Possible values are enumerated as follows:
- varjo_AutoExposureBehavior_Normal
- varjo_AutoExposureBehavior_PreventOverexposure

Possible errors: varjo_Error_OperationFailed, varjo_Error_NotAvailable, varjo_Error_CapabilityNotAvailable, varjo_Error_CameraInvalidPropertyType

Parameters

session	Varjo session handle.
prop	Camera property type.
values	Fills this array with the possible property values. It's either a list or a range depending on the property. This can be determined from GetCameraPropertyConfigType-call.
maxSize	Maximum amount of values that fit into 'values'. Should be >= GetCameraPropertyValueCount().

		varjo_Bool	enabled
	)

Enables video pass through and starts chroma keying for all application layers regardless if they have chroma key flag set.

Varjo system layers are not chroma keyed. This is used as force override to make it possible to run non-MR applications with chroma keying. For application specific chroma keying, use varjo_MRSetChromaKey.

Possible errors: varjo_Error_OperationFailed, varjo_Error_NotAvailable, varjo_Error_CapabilityNotAvailable

Parameters

session	Varjo session handle.
enabled	Toggle global override on/off.

◆ varjo_MRSetEnvironmentCubemapConfig()

void varjo_MRSetEnvironmentCubemapConfig	(	struct varjo_Session *	session,
		const struct varjo_EnvironmentCubemapConfig *	config
	)

Set environment cubemap configuration to select parameters for it.

Before calling this function, environment cubemap config has to be locked successfully with varjo_Lock.

Possible errors: varjo_Error_NullPointer, varjo_Error_OperationFailed, varjo_Error_NotAvailable, varjo_Error_CapabilityNotAvailable varjo_Error_EnvironmentCubemapNotLocked, varjo_Error_EnvironmentCubemapInvalidMode

Parameters

session	Varjo session handle.
config	Pointer to environment cubemap configuration to be applied.

◆ varjo_MRSetVideoDepthEstimation()

void varjo_MRSetVideoDepthEstimation	(	struct varjo_Session *	session,
		varjo_Bool	enabled
	)

Start depth estimation for the video pass through image.

This enables occlusion between VR and MR content when the VR content is submitted as a layer with a depth buffer attachment (varjo_ViewExtensionDepth) and depth testing enabled (varjo_LayerFlag_DepthTesting).

The default depth test range is [0m, 0.75m]. This means that depth test against the video layer is performed only at close distance (hands), and beyond that VR content is always visible. Applications can override this behavior by providing explicit depth test range in varjo_ViewExtensionDepthTestRange extension. In that case, default is not used and depth test is calculated according to the application provided range. This is useful for enabling the full depth range.

This setting is ignored unless varjo_MRSetVideoRender has been enabled.

Possible errors: varjo_Error_OperationFailed, varjo_Error_NotAvailable, varjo_Error_CapabilityNotAvailable

Parameters

session	Varjo session handle.
enabled	On/off toggle.

◆ varjo_MRSetVideoRender()

void varjo_MRSetVideoRender	(	struct varjo_Session *	session,
		varjo_Bool	enabled
	)

Start video pass through rendering on the HMD displays.

Video is rendered as a background layer. i.e. Any application rendering is done on top of the video, unless occlusion is enabled (varjo_MRSetVideoDepthEstimation).

Possible errors: varjo_Error_OperationFailed, varjo_Error_NotAvailable, varjo_Error_CapabilityNotAvailable

Parameters

session	Varjo session handle.
enabled	On/off.

◆ varjo_MRSetVRViewOffset()

void varjo_MRSetVRViewOffset	(	struct varjo_Session *	session,
		double	percentage
	)

Change virtual camera rendering position between user's eyes and video pass through cameras.

The scene is rendered twice from the position of the user's eyes. In full VR the eye position corresponds to the physical position of the user's eyes. When using video pass through there is a physical offset between the user's eyes and the stereo camera pair. So in contrast to full VR, when rendering in MR mode: To remove stereo disparity problems between the real and virtual world and prevent 'floating' of the VR objects anchored to the real world, the scene should be rendered from the physical position of the camera pair in most cases. This is the default mode and corresponds to setting eye offset 'percentage' to 1.0.

But there can be scenes that are predominantly VR where it makes sense to render the scene using the VR eye position. e.g. The scene only contains a small 'magic window' to view the real world or the real world is only shown as a backdrop.

This function can be used to switch the rendering position. It can be used for smooth interpolated change in case it needs to be done the middle of the scene.

Note: This setting is ignored if eye reprojection is enabled (varjo_CameraPropertyType_EyeReprojection). In this case the rendering is always done from the user's eye position (full VR position, corresponds to 'percentage' 0.0).

Possible errors: varjo_Error_OperationFailed, varjo_Error_NotAvailable, varjo_Error_CapabilityNotAvailable

Parameters

session	Varjo session handle.
percentage	[0.0, 1.0] Linear interpolation of the rendering position between the position of HMD user's eyes and the video pass through camera position. Given value will be clamped to the accepted range.

◆ varjo_MRUnlockCameraConfig()

VARJO_DEPRECATED_API void varjo_MRUnlockCameraConfig ( struct varjo_Session * session )

◆ varjo_Unlock()

void varjo_Unlock	(	struct varjo_Session *	session,
		varjo_LockType	lockType
	)

Unlock a previously locked lock.

If the lock was not held by the calling client, varjo_Error_NotLocked error is set. This is the case if the lock is not locked at all or another client has the lock.

Note: After unlocking the lock other applications are free to acquire the lock and access locked features at any time.

Possible errors: varjo_Error_OperationFailed, varjo_Error_NotAvailable, varjo_Error_CapabilityNotAvailable, varjo_Error_NotLocked
