二次曲率-
The result shows that the sufficient and necessary condition of the quadratic rational b - spline curve ' s curvature monotony is similar to the quadratic rational bezier curves ", but its condition is some different from the quadratic rational bezier curves " curve ' s rendering algorithm is an important content in computer graphics, cad
曲線的生成演算法是計算機圖形學的重要內容。對於一些基本曲線，如直線，圓，橢圓等，都有快速生成演算法，如畫直線的bresenham演算法， dda演算法，畫圓的bresenham演算法，中點法，正負法， pitterway的橢圓及拋物線繪制演算法等等。 -
We have more important significance studying quadratic rational b - spline curve ' s curvature monotony. this paper derive the curvature monotony condition for the quadratic rational b spline curves by using the skew coordinate system that can reduces the calculation process. and the curvature monotony condition is compared to the quadratic rational bezier curves "
本論文通過建立斜坐標系，簡化了計算過程，推導出了二次有理b樣條曲線曲率單調充要條件，並與二次有理b zier曲線的曲率單調條件相比較，結果表明：二次有理b樣條曲線曲率單調的充要條件與二次有理b zier樣條曲線相類似，但其條件又有不同。 -
From 1990 ' s, sapidis and others had some studies on quadratic bezier curve ' s curvature monotony and they get this curve ' s sufficient and necessary condition of curvature monotony, but the condition is some strict. in 1998, minerur and some researchers brought forward a high degree curve ' s sufficient condition of curvature monotony. in 2000, wang w. l
從90年代起， sapidis等人對二次b zier曲線的曲率單調性問題進行了研究，得到了曲率單調的充要條件，其條件比較苛刻； 1998年minerur等人提出了一種高次曲線曲率單調的充分條件； 2000年王玉林等人對二次有理b zier曲線曲率單調進行了研究，得到了充要條件。
