MLGraphicsFlags_Headlock	1 << 3	The client will lock all the content to the user's head pose. When enabled all of the content rendered by the app and system notifications will be in head locked mode. Use this mode with caution.
MLGraphicsFlags_Default	0	When #graphics_flags is set to default, the client configuration returned is the default configuration (color/depth, origin lower left, non-debug, no headlock).
MLGraphicsFlags_Ensure32Bits	0x7FFFFFFF	Ensure enum is represented as 32 bits.

Deprecated since 1.6.0. Scheduled for removal.

MLGraphicsRenderBufferInfo

typedef struct MLGraphicsRenderBufferInfo MLGraphicsRenderBufferInfo;

Definition of a single buffer entry for all virtual cameras as defined in MLGraphicsRenderTargetsInfo.

More Info

Deprecated

Deprecated since 1.6.0. Scheduled for removal.

MLGraphicsRenderTargetsInfo

typedef struct MLGraphicsRenderTargetsInfo MLGraphicsRenderTargetsInfo;

The complete definition of all possible buffered entries along with associated metadata.

Statically defined after successfully creating the client, the MLGraphicsRenderTargetsInfo provides the definition of all of the buffered entries along with the global metadata.

    MLGraphicsFrameInfo * out_frame_info
)

Request to begin rendering a new frame in the graphics system.

MLGraphicsFrameInfo *	out_frame_info	Information returned for use when rendering the frame. Only valid if result is MLResult_Ok.

MLResult	MLResult_UnspecifiedFailure	Failed to start frame due to an unknown error.

Required Permissions:

None

Called to request the start of a new render frame and should be called as close as possible to the start of rendering to minimize the motion to photon latency. Only one frame can be rendered at a time and must be submitted by providing the returned handle to MLGraphicsEndFrame prior to another call to MLGraphicsBeginFrameEx. The call to begin/end frame should be made on the render thread alone of the client. It is required that a successful call to MLGraphicsFrameInfoInit be made before calling MLGraphicsBeginFrameEx. Faiure to call MLGraphicsFrameInfoInit before calling MLGraphicsBeginFrameEx will return a result of MLResult_NotImplemented.

Note : Calls to MLGraphicsBeginFrameEx can and will block the calling process. There are several reasons that lead to a block, including, the client is executing faster than the defined timing requested (and the block re-aligns the client timing), the client is not yet visible in the system, and the compositor has not yet moved to the next buffered entry (i.e. wraparound cases from fast client rendering). The call to MLGraphicsBeginFrameEx will timeout the block and return when the conditions to unblock have not been satisfied for the internal timeout period. The most common occurrence of the timeout is when the application is not currently visible.

API Level:

MLGraphicsSignalSyncObjectGL

MLResult MLGraphicsSignalSyncObjectGL(

)

Signal the sync object provided for each virtual camera for GL/GLES clients.

Parameters

Returns


MLResult	MLResult_InvalidParam	Failed to signal object due to an invalid input parameter.

MLResult	MLResult_UnspecifiedFailure	Failed to signal object due to an unknown error.

Required Permissions:

None

Required for each frame, after rendering each virtual camera (or multiple if stereo rendering) to signal the sync object in order to inform the graphics system that the rendering for the camera(s) has completed. All sync objects can be signaled after rendering all cameras, but results in lower fidelity in the graphics system.

Parameters


MLHandle	graphics_client	The graphics client in which to query the performance.
MLGraphicsClientPerformanceInfo *	out_info	Current performance information for the client. Only valid if result is MLResult_Ok.

Returns


MLResult	MLResult_InvalidParam	Failed to obtain client performance metrics due to an invalid input parameter.
MLResult	MLResult_Ok	Successfully obtained client performance metrics.
MLResult	MLResult_UnspecifiedFailure	Failed to obtain client performance metrics due to an unknown error.

Required Permissions:

None

Can be called any time after the client has begun rendering frames to obtain the internally tracked performance metrics for the client and graphics system. Updated internally once per completed frame.

Deprecated

Deprecated since 1.6.0. Scheduled for removal.

MLGraphicsSetGlobalDimmer

MLResult MLGraphicsSetGlobalDimmer(
    MLHandle graphics_client,
    float dimmer_value
)

Set the value for the global dimmer.

Parameters


MLHandle	graphics_client	The graphics client handle.
float	dimmer_value	Floating point dimmer value in valid range [0.0 to 1.0]. 0.0 corresponds to min user defined value while 1.0 corresponds to max user defined value.

Returns


MLResult	MLResult_InvalidParam	Auto global dimmer value could not be set due to an invalid parameter.
MLResult	MLResult_Ok	Auto global dimmer value set successfully.
MLResult	MLResult_UnspecifiedFailure	The operation failed with an unspecified error.

Required Permissions:

None

Can be called any time after the client has been created. Updates are reflected in the next client submitted frame (via MLGraphicsEndFrame). Any smooth ramping from auto dimmer to application final dimmer should be handled by the application itself. Since the dimmer value set through MLGraphicsSetGlobalDimmer() is reflected only in the next client submitted frame, the smooth ramp stepping interval is equal to current application frame rate. Dimmer values correspond to a global dimming range defined by the user in the settings.

Deprecated

Deprecated since 1.6.0. Scheduled for removal.
