摘要
针对非均匀有理B样条(NURBS)曲线形状微调的一种新方法。插值NURBS曲线控制点构造一条B样条曲线,通过调整插值B样条曲线的控制点来调整NURBS曲线的形状。此外,用权点表示控制点,通过调整权点可以交互地修改NURBS曲线的形状。实验结果表明,该方法在解决NURBS曲线形状调整的效率上十分有效。
A new method for the trivial shape adjustment of NURBS curve is proposed. The B-spline curve is constructed to interpolate the control points of NURBS curve. By adjusting the B-spline curve the control points of NURBS curve are modified, and then the shape of NURBS curve is adjusted. Besides, weighted points are used to denote the control points. The shape of NURBS curve is modified by adjusting weighted points, which can modify the shape of NURBS. curve interactively. Experimental results demonstrate that the method developed is fairly efficient for solving the trivial shape adjustment of NURBS curve.
