C Specification

The XrSpatialMarkerStaticOptimizationEXT structure is defined as:

// Provided by XR_EXT_spatial_marker_tracking
typedef struct XrSpatialMarkerStaticOptimizationEXT {
    XrStructureType    type;
    const void*        next;
    XrBool32           optimizeForStaticMarker;
} XrSpatialMarkerStaticOptimizationEXT;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain.

  • optimizeForStaticMarker indicates if all markers in the space are expected to not move.

Description

If XR_SPATIAL_CAPABILITY_FEATURE_MARKER_TRACKING_STATIC_MARKERS_EXT is enumerated by xrEnumerateSpatialCapabilityFeaturesEXT for a certain capability, and if the application chains XrSpatialMarkerStaticOptimizationEXT to the corresponding configuration structure of that capability, the runtime must assume that all markers detected are static if optimizeForStaticMarker is set to XR_TRUE. This allows the runtime to generate a more accurate pose and size. This structure must be linked into the next chain of XrSpatialCapabilityConfigurationQrCodeEXT, XrSpatialCapabilityConfigurationMicroQrCodeEXT, XrSpatialCapabilityConfigurationArucoMarkerEXT, or XrSpatialCapabilityConfigurationAprilTagEXT.
