+E3x is a JAX library for constructing efficient E(3)-equivariant deep learning architectures built on top of Flax. The goal is to provide common neural network building blocks for E(3)-equivariant architectures to make the development of models operating on three-dimensional data (point clouds, polygon meshes, etc.) easier.
