C Specification

When this extension is enabled, an application can pass in an XrSystemSpaceWarpPropertiesFB structure in the XrSystemProperties::next chain when calling xrGetSystemProperties to acquire information about recommended motion vector buffer resolution. The XrSystemSpaceWarpPropertiesFB structure is defined as:

// Provided by XR_FB_space_warp
typedef struct XrSystemSpaceWarpPropertiesFB {
    XrStructureType    type;
    void*              next;
    uint32_t           recommendedMotionVectorImageRectWidth;
    uint32_t           recommendedMotionVectorImageRectHeight;
} XrSystemSpaceWarpPropertiesFB;


Member Descriptions
  • type is the XrStructureType of this structure.

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

  • recommendedMotionVectorImageRectWidth: recommended motion vector and depth image width

  • recommendedMotionVectorImageRectHeight: recommended motion vector and depth image height
