C Specification

The XrSemanticLabelMETA enumeration is defined as:

// Provided by XR_META_spatial_entity_semantic_label
typedef enum XrSemanticLabelMETA {
    XR_SEMANTIC_LABEL_UNKNOWN_META = 0,
    XR_SEMANTIC_LABEL_FLOOR_META = 1,
    XR_SEMANTIC_LABEL_CEILING_META = 2,
    XR_SEMANTIC_LABEL_WALL_FACE_META = 3,
    XR_SEMANTIC_LABEL_INNER_WALL_FACE_META = 4,
    XR_SEMANTIC_LABEL_INVISIBLE_WALL_FACE_META = 5,
    XR_SEMANTIC_LABEL_DOOR_FRAME_META = 6,
    XR_SEMANTIC_LABEL_WINDOW_FRAME_META = 7,
    XR_SEMANTIC_LABEL_MAX_ENUM_META = 0x7FFFFFFF
} XrSemanticLabelMETA;

Description

Enumerant Descriptions

  • XR_SEMANTIC_LABEL_UNKNOWN_META  — Unknown. This is a valid label that is used when the runtime is not able to classify the entity using another label, or when the application does not recognize the label.

  • XR_SEMANTIC_LABEL_FLOOR_META  — Floor of a room or space.

  • XR_SEMANTIC_LABEL_CEILING_META  — Ceiling of a room or space.

  • XR_SEMANTIC_LABEL_WALL_FACE_META  — Wall face of a room or space. Wall faces, along with invisible wall faces, are used to define the outer boundary of a room.

  • XR_SEMANTIC_LABEL_INNER_WALL_FACE_META  — Inner wall face, which is a wall face that exists inside a room and is not connected to the outer boundary of the room. For example, a pillar that exists at the center of a room may be represented by using four inner wall faces.

  • XR_SEMANTIC_LABEL_INVISIBLE_WALL_FACE_META  — Invisible wall face, which is used to conceptually separate a space (e.g., separate a living space from a kitchen space in an open floor plan house even though there is no real wall between the two spaces).

  • XR_SEMANTIC_LABEL_DOOR_FRAME_META  — Door frame, which usually exists on a wall face.

  • XR_SEMANTIC_LABEL_WINDOW_FRAME_META  — Window frame, which usually exists on a wall face.
