So the travel and time around the SAS2024 conference allowed me finally to work on some software that was in dire need of attention. One of these software pieces was a tool that I’ve been using for years to educate people on what Fourier Transforms do, and how they let you easily see how real-space shapes and lattices scatter. It has been gaining following of people who use it for their educational lectures as well. Some people also like it to get a bit of an intuitive feel for how FTs work.
After a little refactoring, this code is now updated and in much better shape. Everything works again in Python 3.12, and (by leveraging PyTorch), it now has a framerate of 30 FPS on my M1 MacBook. it’s a far cry from the 2-4 FPS I was getting long ago.
While the current version needs to be launched using a Python environment, we’ll hopefully soon have a compiled version again for you, to make it even easier to launch. There will be a short publication coming out on this to advertise the software a bit further, and I will be recording a new demo video of it soon so you can see how it can be used in a lecture. The new repository can be found here, and, as always, contributions are very welcome.
