meetod detailide haldamiseks 3D mudeli esitlustes, lihtsustades aluseks olevaid kujundeid. Selleks vähendatakse tippude, servade või nägude arvu, mis moodustavad 3D-mudeli ehitusplokkidest koosnevate hulknurkade pinnad, a technique for managing the details in 3D model representations by simplifying the underlying shapes. This is done by reducing the number of vertices, edges or faces which make up the surfaces of the polygons that form the building blocks of the 3D model, оптимизация модели, путём ужимания количества вертексов и полигонов
