The specialty of this system lies in the interface for controlling the sub algorithms of rendering pipeline . according to different needs , users can process freely like choosing interpolating and compositing algorithms , choosing viewing direction and manipulating the opacity value etc . ; the design of system is based on independent models , therefore it ' s easy to be extended . for those functions possible applicable in the future can be integrated through pre - defined interfaces in the system 系統的特色在于實現了體繪制算法各個步驟的控制接口,通過人機交互用戶可以根據需要進行如下操作:選擇插值算法、合成算法,選擇觀察角度和阻光度(不透明度)的賦值等:系統的設計是基于模塊的,具有很強的可擴展性,對于未來可能需要實現的功能都可以通過預留的系統接口方便地集成進來。
