Code to convert between various geometric transformations.
- Composing rotations / zooms / shears / translations into affine matrix;
- Decomposing affine matrix into rotations / zooms / shears / translations;
- Conversions between different representations of rotations, including:
- 3x3 Rotation matrices;
- Euler angles;
- quaternions.
We have tried to document the algorithms carefully and write clear code in the
hope that this code can be a teaching reference. We document the math behind
some of the algorithms using sympy in
transforms3d/derivations. We would be very pleased if y'all would like to
add your own algorithms and derivations - please get a copy of the code from
https://github.com/matthew-brett/transforms3d and get on down,
algorithmically. Feel free to use the github issue tracker and pull request
system to ask for advice and support.

Released under the BSD two-clause license - see the file LICENSE in the
source distribution.
Much of the code comes from transformations.py by Christoph Gohlke, also released under the BSD license.
We use Github actions to test the code automatically under Pythons 3.7 through 3.10.
We depend on numpy >= 1.15. You may be able to make it work on an earlier numpy if you really needed that.
The latest released version is at https://pypi.python.org/pypi/transforms3d
Please put up issues on the transforms3d issue tracker.
