做什么事情
学习 brep 的sdf表示
意义
- brep方便控制
- sdf方便运算和智能生成
怎么做
数据准备
数据源： furniture 文件结构 brep( .step ) train chair chair_1.brep chair_2.brep test val sdf ( .npz ) train chair chair_1.sdf.npz chair_2.sdf.npz
数据结构
brep to mesh
基本思路：采样，然后三角化
- 重采样 《Mesh Generation from CAD Models》: sharp edge
mesh to sdf
基本思路：体素，然后积分
docker
docker run -it -v /mnt/disk2/dataset:/data -v $(pwd):/app --name brep_sdf ubuntu:22.04
