Overview

Who this competition fits

适合已有计算几何或CAD内核开发背景的开发者,尤其是能用C++在OpenCASCADE 7.70或SGK上处理NURBS曲面、圆柱/圆锥/球面等解析曲面的人。也适合能完成算法设计、测试数据、技术报告和代码仓库协作的小团队。

Preparation

From registration to a first submission

  1. 01

    NURBS曲面几何

  2. 02

    二次曲面参数化

  3. 03

    C++

  4. 04

    OpenCASCADE 7.70 或 SGK

  5. 05

    几何误差与连续性分析

  6. 06

    单元测试与性能测试

Before you commit: 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。
