geometricalgebra

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()
