C Specification

The XrSceneMeshSemanticLabelANDROID enumeration is the default set of semantic labels that can be used to label mesh vertices to describe which physical environment surface the mesh vertex is on. This enum set is represented by the XR_SCENE_MESH_SEMANTIC_LABEL_SET_DEFAULT_ANDROID value in XrSceneMeshSemanticLabelSetANDROID.

// Provided by XR_ANDROID_scene_meshing
typedef enum XrSceneMeshSemanticLabelANDROID {
    XR_SCENE_MESH_SEMANTIC_LABEL_OTHER_ANDROID = 0,
    XR_SCENE_MESH_SEMANTIC_LABEL_FLOOR_ANDROID = 1,
    XR_SCENE_MESH_SEMANTIC_LABEL_CEILING_ANDROID = 2,
    XR_SCENE_MESH_SEMANTIC_LABEL_WALL_ANDROID = 3,
    XR_SCENE_MESH_SEMANTIC_LABEL_TABLE_ANDROID = 4,
    XR_SCENE_MESH_SEMANTIC_LABEL_MAX_ENUM_ANDROID = 0x7FFFFFFF
} XrSceneMeshSemanticLabelANDROID;
