It described the store rules of workpieces point , the organization rules of workpiece triangle and the rule definition of dynamically inserting points and deleting points in the process . base on upwards algorithm , one suit of manufacture simulation models was built 本文對加工過程中三維圖形動畫顯示問題進行了深入的探討,給出了一套工件上點的存儲規(guī)則、工件上三角形的組織規(guī)則和在加工過程中向工件中動態(tài)插入點和刪除點的規(guī)則定義。
In this part , how to access the spatial data file in a complex way by sdf component toolkit , not only to add , search and delete point - shaped map features , but also to add , search and delete polyline - shaped and polygon - shaped map features was provided in this thesis 本文在這部分中,利用sdfcomponenttoolkit對空間數(shù)據(jù)文件進行了復(fù)雜的訪問和修改,不但實現(xiàn)了點狀地理元素的添加、查找、刪除,而且實現(xiàn)了線狀、多邊形狀地理元素的添加、查找、刪除。
