Declaration
var levelsOfDetail: [SCNLevelOfDetail]? { get set }Discussion
Because rendering a complex geometry incurs a performance cost, you can use level-of-detail objects to substitute simpler geometries in its place as its distance from the point of view camera increases (or its apparent size decreases). For details, see SCNLevelOfDetail.
