XrSystemSpaceWarpPropertiesFB(3)

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;

Members

Member Descriptions

type is the XrStructureType of this structure.
next is NULL or a pointer to the next structure in a structure chain.

recommendedMotionVectorImageRectHeight: recommended motion vector and depth image height

Description

Valid Usage (Implicit)

The XR_FB_space_warp extension must be enabled prior to using XrSystemSpaceWarpPropertiesFB
type must be XR_TYPE_SYSTEM_SPACE_WARP_PROPERTIES_FB
next must be NULL or a valid pointer to the next structure in a structure chain
