基於點的計算機圖形學綜述 -
After studying a lot of documents of computer - graphics and computation of geometrical, based on nurbs, which is a pop expression to describe curve and surface, the author put forward a method ? ? to identify bad point by most excursion, to illustrate how to choose smooth base plane, which is not referred in most documents, and to introduce optimize method of operational research to combine surfaces, especially for surfaces combination with vertex, and improvement of combination effect
在解決多曲面有角點的拼接問題中引入了運籌學的優化方法，改善了多曲面拼接的效果，而且在ugii造型軟體的基礎上，用visualc + + 、 ug / openapi進行二次開發，加入了壞點剔除，曲線光順，曲面片之間的拼接等功能，很好的解決了反求工程中所遇到的問題。 -
Based on the analysis of designed cad graphics and the given parameters, computer can convert the cad graphics to a acdbpolyline which can simulate the routine of the conveyor chain. then by using the method of point - by - point strain calculation, computer could figure out each point ’ s strain of the chains under different load states, and get the results such as strain ’ s maximal and the minimal values and their positions, weight of the strain equipment and power of the drive electric - machinery that the conveyor need
通過對設計的cad圖形和給定參數的分析，將輸送鏈運行軌跡轉化為一條可模擬輸送鏈軌跡的多義線，然後用逐點張力計演算法動態地計算出各種加載狀態下輸送鏈上各點的受力，得出最大、最小受力點的力的大小和位置，拉緊裝置的重量，驅動電機所需的功率等結果。 -
V ) based on cbr ( cased - based reasoning ) principle and characteristic of garment structure graphics design - strong experience - oriented, this paper selects cbr as the basic theory of intelligent subsystem, which creatively combines point - grading, vectorgraph method, theory of fuzzy reasoning and bezier curve algorithm together and devise case reuse and revise algorithm
（ 5 ）在基於實例推理（ cbr ）原理及服裝結構圖形設計特點?強經驗性的基礎上，選用cbr為基於autocad的服裝結構圖形設計子系統的解決方案。創造性的將點位移及矢量法膜糊推理原理和bezier曲線演算法相結合，設計了實例重用和實例修正演算法。 -
Based on the point of image - based rendering, and the technology of virtuality and reality combining, it yield the conception of virtual globe and its related thought, and takes the dispersed pixel element mutation as the nucleus, the principle of utilization geometry and graphics, 3d walk around is realized and true sense controls waits has carried on a series of research, has put forward the corresponding mathematical model, and has been in progress the improvement, and has got the better result to the tradition method
本文從基於圖像生成的角度出發，由虛實結合的構思引出了視球及其相關概念，並以離散的像素變換為核心，利用幾何學和圖形學的原理，在三維漫遊的實現及真實感控制等方面進行了一系列的研究，提出了相應的數學模型，對傳統方法進行了改進，得到了較好的結果。
