vector polygon

基本解釋

The algorithm of transferring vector polygon to raster data is one of the basic algorithms of GIS.
矢量多邊形的柵格化算法是地理信息系統(tǒng)的基礎(chǔ)算法之一。
At the same time the author points out that the polygon vertexes can be sorted clockwise or anticlockwise by judging the sign of the vector polygon area.
同時(shí)指出可以通過(guò)判斷矢量多邊形面積的正負(fù)值將多邊形的頂點(diǎn)按照順時(shí)針或逆時(shí)針?lè)较蚺判颉?/li>
The differential method for the mechanic movement analysis is proposed in this paper. With the method, only the displacement vector polygon of a mechanism is needed to be established.
導(dǎo)數(shù)法機(jī)構(gòu)運(yùn)動(dòng)分析只需建立運(yùn)動(dòng)機(jī)構(gòu)的位移矢量多邊形，然后利用位移、速度、加速度之間的函數(shù)關(guān)系來(lái)完成速度、加速度分析。
