# Shapely3D
* **简介**
基于shapely1.8.1的三维矢量表达和空间计算
* **安装方式**
```
## python version >= 3.8
pip install shapely3d
```
* **使用方式**
```
## 几何实例类
from shapely3d import Point3D as Point, LineString3D as LineString, Polygon3D as Polygon
## 空间计算类
from shapely3d import wkt3D, ops3D, affinity3D
```
* **空间计算**
二维三维转换
`ops3d.trans_3d_2d / ops3d.trans_2d_3d / ops3d.judge_2d_3d`
三维实体表征
`Point3D(0,0,0) / LineString3D([[0,0,0],[1,1,0]])`
三维度量运算
`ops3D_smp.distance_point_point / ops3D_smp.points_line_distance`
三维关系运算
`point_1.intersects(line_1) / ops3D.unary_union`
三维仿射运算
`affinity3D.rotate / affinity3D.scale`
三维插值运算
`ops3D.substring / ops3D.interpolate`
* **依赖库**
`numpy, numba, shapely==1.8.1`
* **更新记录**
* v1.4.2：修正intersection_np算法，适配两线段恰好头尾相连的情况
* v1.4.1：修正intersection_np算法，适配两线段平行且重叠的情况
* v1.4：修正difference
* v1.3：更新setup.py
* v1.2：更新README
* v1.1：新增simplify、difference的三维实现，优化intersection_np
* v1.0：初始提交
