与平面相交 meaning in English

intersects with plane

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
对两曲面求交问题，当曲面细化足够小时，曲面求交可近似看成曲面与平面相交问题，引进了边界点的概念，因此只要知道交线上的任意点，就可以将跨越许多曲面片的整条交线计算出来，所求出的交线或者跨越曲面的边界，或者形成交线环；从初始点出发跟踪求解整条交线的过程中，步长的选择采用了通过曲面片曲率来约束的方法，用该方法求出的交点在不同曲面片上的分布数目不与弦长成正比；该求交方法包含了各曲面片的边界线与交线的交点的求解，可获得边界交点的坐标值及其参数值。
