Show HN: Geomatic – a command-driven geometry studio enabled with autodiff
https://www.tinyvolt.com/geomatic
All commands have the format `output = \func inputs` or just `\function inputs`. Points and scalars are built on the fly. Eg `\line a b` to an empty canvas creates points `a` and `b`, and joins them with a line.One can use broadcasting semantics similar to NumPy and PyTorch in a visual setting (imagine creating a list of circles where one dim corresponds to radius and another to the center). One can also use backpropagation, run gradient descent or visualize vector fields. Almost everything is reactive so changing a variable updates all of the downstream geometry. It also allows anyone to write and load their own visualization, which can be broadcasted and differentiated through.

The person it benefits the most is the author, when they are building it and the errors-per-use are as high as they’ll (hopefully) ever be.
- When I open an example, I expected to actually... see an example. I'm not gonna read the wall of text. I don't even understand what this is yet, that's why I tried to see an example.
If you want to look through a video or something, then this tool is likely not for you! (nothing bad with that, that's why it's great that there are so many different tools we can choose from)
