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(tǒng)的特色在于實(shí)現(xiàn)了體繪制算法各個(gè)步驟的控制接口,通過人機(jī)交互用戶可以根據(jù)需要進(jìn)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(tǒng)的設(shè)計(jì)是基于模塊的,具有很強(qiáng)的可擴(kuò)展性,對(duì)于未來可能需要實(shí)現(xiàn)的功能都可以通過預(yù)留的系統(tǒng)接口方便地集成進(jìn)來。
