If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
三角网格处理
计算几何
非流形与自交检测
SDF（有符号距离场）
GPU性能优化
可复现实验环境配置
The real friction is usually not library usage. It is validation, time allocation, and task framing.
难点不只是把网格补成封闭体，而是在修复非水密缺陷时尽量不改变原始几何与拓扑细节，同时兼顾计算速度和重建精度。作品还必须提交可复现的完整代码、运行环境和较完整的技术报告，获奖作品需按要求开源。
This guide is the best pre-read if you want a cleaner start instead of trial-and-error.
How to learn feature engineering, validation, and competition workflow without heavy hardware.
