python中的好几何库？ [英] Good geometry library in python?

问题描述

• 评估两个交点之间的交点2D和3D线（如果存在）


• 评估平面和线之间的交点或两个平面之间的交线


• 评估线和点之间的最小距离
  
• 找到穿过点的平面的正交坐标


• 旋转，平移，镜像一组
  
• 找到由四个点定义的二面角

  我有一本指南所有这些操作，我都可以实现，但不幸的是我没有时间，所以我会喜欢一个图书馆。大多数操作对于游戏目的都很有用，所以我确信这些功能中的一部分可以在游戏库中找到，但我不希望包含我不需要的功能（如图形）。

  
  
  

  有什么建议吗？感谢

  解决方案

  也许看看 SymPy 。

  
  

  I am looking for a good and well developed library for geometrical manipulations and evaluations in python, like:

  • evaluate the intersection between two lines in 2D and 3D (if present)
  • evaluate the point of intersection between a plane and a line, or the line of intersection between two planes
  • evaluate the minimum distance between a line and a point
  • find the orthonormal to a plane passing through a point
  • rotate, translate, mirror a set of points
  • find the dihedral angle defined by four points

  I have a compendium book for all these operations, and I could implement it but unfortunately I have no time, so I would enjoy a library that does it. Most operations are useful for gaming purposes, so I am sure that some of these functionalities can be found in gaming libraries, but I would prefer not to include functionalities (such as graphics) I don't need.

  Any suggestions ? Thanks

  解决方案

  Perhaps take a look at SymPy.
