Constructive solid geometry 構造實體幾何
A quick visible algorithm based on dynamic constructive solid geometry reconstruction 基于構造實體幾何模型動態重構的快速顯示算法
? to make the solid have realistic surface , we adopt advanced solid modeling method - constructive solid geometry . ? to free end - user from overwork , we presents and realizes many auto - processing algorithms , such as searching of inner - point , definition of polygon ' s counter - clockwise direction , as well as generation of numeric control codes . ? to checkout the collision and interference between cutter and part , we accomplish numeric control machining simulation , which can help end - user validate the correctness and rationality of numeric control codes , so it is needless that do repetitive test - cut before normal manufacture 正如將在后續章節中所講述的那樣,我們在系統中采用了許多先進的技術,其中主要包括以下幾點:采用分層設計思想,使三維物體的設計得到了簡化;采用先進的實體造型方法,使所建立的實體真實感強;實現了內點自動查找、多邊形方向自動定義等算法,提高了系統的自動化水平;實現了刀具軌跡的自動生成、優化;實現了數控代碼的自動編寫,克服了手動編寫的缺點;實現了數控加工仿真,能檢驗數控代碼的正確性和合理性,并能自動檢測刀具與工件之間的干涉。
