On the above basis , the frontal method and rectangle method are proposed , the relationships between memory spending for both methods and amount of nodes are given 據(jù)此,提出了有限元網(wǎng)格結(jié)點(diǎn)編號的前沿法與矩形法,并給出了這兩種編號法的內(nèi)存消耗與結(jié)點(diǎn)數(shù)量的關(guān)系。
It is reali zed that the invisible part of the object can be shadowed , using the max imum or minimum enveloping rectangle method and the counter of points of intersection method , etc . ( 3 ) the boolean operation between integrity or unintegrity bodys is supplied 分析并討論了形體產(chǎn)生隱藏線、隱藏面的原因,利用了最大最小外包矩形法、交點(diǎn)記數(shù)法等,實(shí)現(xiàn)了任意形體的消隱算法。 ( 3 )完成了形體間的正則、非正則布爾運(yùn)算。
百科解釋
In mathematics, specifically in integral calculus, the rectangle method (also called the midpoint or mid-ordinate rule) computes an approximation to a definite integral, made by finding the area of a collection of rectangles whose heights are determined by the values of the function.
