C Specification

The XrSceneSubmeshStateANDROID structure is defined as:

// Provided by XR_ANDROID_scene_meshing
typedef struct XrSceneSubmeshStateANDROID {
    XrStructureType    type;
    void*              next;
    XrUuid             submeshId;
    XrTime             lastUpdatedTime;
    XrPosef            submeshPoseInBaseSpace;
    XrExtent3Df        bounds;
} XrSceneSubmeshStateANDROID;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

  • submeshId is an XrUuid identifying the submesh.

  • lastUpdatedTime is an XrTime representing the time when the submesh was last updated.

  • submeshPoseInBaseSpace is an XrPosef representing the pose of the submesh in the base space used to create the scene mesh snapshot. The pose is also the center of the submesh bounding box.

  • bounds is an XrExtent3Df describing the dimensions of the bounding box that encloses the submesh. This bounds is defined in the base space that was used to create the scene mesh handle.

== Description

The runtime makes best effort to map submeshId with the region of the physical space occupied by the submesh. The Runtimes may at any time lose this mapping and assign a new UUID to any subset of the detected submeshes. In particular runtimes are not required to reuse the same UUIDs for the same meshes in subsequent application instances.
