反算B_spline三次曲面控制顶点构造义齿几何模型，有具体应用-B_spline three-count surface tectonic control vertices denture geometric model, a specific application

java写的非均匀B样条插值曲线，从Excel导入原始数据，然后反算控制节点，最后将所有插值点导出到Excel中-java app for non-uniform B-spline interpolation curve, importing raw data from Excel, and then inverse control node, and finally to export to Excel all interpolation points
