摘要針對(duì)石油化工設(shè)備建造中，缺乏一種高效的器壁開(kāi)孔畫曲線方法的問(wèn)題，研制了一種能在非平面器壁上畫開(kāi)孔曲線的畫線規(guī)。 - Secondly , the problem of the curve - surface mutual transforming and smooth - finishing have been analyzed farther . for the surface intersecting problem : owing to the introduction of the boundary points , as long as the intersecting points on a certain line , the full intersecting line can be gained . the intersecting line either intersects at the boundary of the triangle surface or forms the loop ; during the course of tracking , the selecting of the pace is restricted by the curvature , the number of the gained intersecting points are not in proportion as the chord - length ; the intersecting points not only record the coordinate and store the parameter
對(duì)兩曲面求交問(wèn)題，當(dāng)曲面細(xì)化足夠小時(shí)，曲面求交可近似看成曲面與平面相交問(wèn)題，引進(jìn)了邊界點(diǎn)的概念，因此只要知道交線上的任意點(diǎn)，就可以將跨越許多曲面片的整條交線計(jì)算出來(lái)，所求出的交線或者跨越曲面的邊界，或者形成交線環(huán)；從初始點(diǎn)出發(fā)跟蹤求解整條交線的過(guò)程中，步長(zhǎng)的選擇采用了通過(guò)曲面片曲率來(lái)約束的方法，用該方法求出的交點(diǎn)在不同曲面片上的分布數(shù)目不與弦長(zhǎng)成正比；該求交方法包含了各曲面片的邊界線與交線的交點(diǎn)的求解，可獲得邊界交點(diǎn)的坐標(biāo)值及其參數(shù)值。
