If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
NURBS曲面几何
二次曲面参数化
C++
OpenCASCADE 7.70 或 SGK
几何误差与连续性分析
单元测试与性能测试
The real friction is usually not library usage. It is validation, time allocation, and task framing.
难点不只是把曲面拟合成二次曲面，而是在工业精度、边界吻合与相邻曲面G0/G1连续性约束下，稳定地区分“可转换”和不可转换的NURBS，并给出可追溯的异常处理。作品还要兼顾CAD操作性能、连续批处理稳定性，以及完整测试、较高代码注释率和测试覆盖要求。
This guide is the best pre-read if you want a cleaner start instead of trial-and-error.
