摘要
Hetmite插值弧长函数的反函数 ,为参数曲线引入弧长参变量 .插值公式是保单调和C2 连续的 ,从而在实现弧长参数化时 ,节点处单位切矢 ,并保持参数曲线几何形状和C2 连续性 .
Inverse arc—length is interpolated for arc—length parameterization.The interpolator is monotony preserving and C 2—continuous,hence,the nearly arc—length parameter curve has unit tangent vector,it preserves thre geometric profile and C 2—continuous of the original parameter curve.A instance shows the efficiency as applying the interpolator to arc—length paraneterization.
