构造的曲线 meaning in English
constructed curves
Examples
- The constructed curve was shape - preserving to the polygon
所构造的曲线对多边形具有保形性。 - 6 brodlie k w ed . . a review of methods for curve and function drawing . mathematical methods in computer graphics and design , london , uk : academic press , 1980 , pp . 1 - 37
结果表明，新方法选取的节点构造的曲线具有数据点建议的理想形状，而其他三种方法分别对某些数据不能给出令人满意的结果。 - In the forth chapter , we proposes an approach of constructing planar piecewise bezier curve of 3rd 4th and 6th degree with all edges tangent to a given control polygon and the curve segments are joined together with c1 c2 and c3 - continuity . the segmented bezier curves are all shape - preserving to their tangent polygon
第四章讨论与给定多边形相切的分段三次、四次、六次b zier曲线，所构造的曲线c ~ 1 、 c ~ 2 、 c ~ 3 -连续，并且对切线多边形是保形的。 - Comparing with the quadratic b - spline curve , they have advantages by themselves : firstly , the shape of the curves can be adjusted locally by the parameters i ; secondly , the curves formed by blending functions of degree 4 can be g2 continuous . in addition , in order to meet various requests for continuity of curves in practical applications , corresponding polynomial functions can be used to construct the curves
但与二次均匀b样条曲线相比，它们还有其自身的优点：首先，曲线的形状都可用参数_ i进行局部调整：其次，四次调配函数所构造的曲线就可达到g ~ 2连续；另外，为了满足实际应用中对曲线连续性的不同要求，可使用相应次数的调配函数来构造曲线。
