geometricalgebra's Introduction

geometricalgebra

badge

Library implementing conformal geometric algebra.

The key features are:

  • Fast numerical implementation of multivector and its exterior algebra
  • The library supports various backends (numpy, tensorflow, jax)
  • Full support of autograd works when using jax and tensorflow
  • All operation work for single multivector or tensors of multivector. Broadcasting is also supported.

Installation

pip install geometricalgebra

Example

from geometricalgebra import cga3d
a = cga3d.e_0
b = cga3d.e_1.up()
c = cga3d.e_2.up()
circle = a ^ b ^ c
# The radius of a circle going through [0, 0, 0], [1, 0, 0], and [0, 1, 0]
radius = circle.circle_to_center_normal_radius()[2].to_scalar()

geometricalgebra's Issues

Publish to PyPI

The project needs proper release tagging and should publish to PyPI

Fix some typos / grammar

Hihi,

I spotted some small typos, just in this one file basically:

ConformalGeometricAlgebra.ipynb:

  • obejcts
  • quaterions
  • how object can be --> how objects can be
  • easy --> easily
  • more vectors result in an objects --> more vectors results in an object
  • elemetary
  • very compact --> in a very compact way

Plus there's an it that should be an its in `README.md.

poetry add fails on mac with apple m2

Hi,
i tried to add the package but it failed on my mac with the apple m2:

(meander-pcd-py3.9) ➜  meander-pcd git:(main) ✗ poetry add geometricalgebra==0.1.1
