Objectarx software kit is used for working drawing. drawing block classes are designed for drawing. when the result of the data computing is passed into painting block, the drawing block objects are created and the objects are added into system graphic database, thus the working drawing is auto _ drawn
同樣，對繪圖程序的開發，也是先定製了一系列圖塊類，整個施工圖就由這些圖塊類構成；在類定製完畢后，將計算程序的計算結果傳入繪圖程序中，然後創建圖塊類的對象，將這些對象加入系統圖形數據庫，自動生成施工圖。 -
First, the basic raster graphics algorithms for drawing 2d primitives are introduced, including edge coherence and the scan - line algorithm of triangle, brush algorithm of thick line ( and its improved method ) and midpoint circle and ellipse algorithm ; and the current situation of the advanced algorithms is also involved. second, the mapping of high level programming language to hardware description language is described, some principles of the conversion of algorithm to state machine are proposed also ; then, the implementation of basic graphics in hardware is discussed in detail, the state machines are drawn in the paper, and the interfaces of hardware are defined, block diagrams too, and the advanced algorithm of conic is proved ; finally, some issues about test are described, the results of simulation and synthesis are given in the last, and some detailed data are displayed in the appendix
首先介紹了現有的基本圖形生成演算法，包括三角形邊相關掃描演算法，寬直線的線刷子演算法及其改進和圓形、橢圓的生成演算法，同時介紹了加速演算法的研究現狀；然後，討論了高級語言描述到硬體描述語言的映射，提出了演算法到狀態機抽象的規律；接著具體討論了基本圖形的硬體實現，給出了各演算法的狀態機圖，介面定義和實現框架，並且從理論角度給出了二次曲線加速演算法的證明：最後採用軟體工具進行測試驗證，給出了模擬、綜合實現的結果，並在附錄中有詳細的實驗結果數據。
