Show HN: Geomatic – a command-driven geometry studio enabled with autodiff

Geomatic, a command-driven geometry studio with automatic differentiation, allows users to create and manipulate points, lines, and scalars using simple command syntax. The tool supports NumPy-like broadcasting for visual geometry, backpropagation, gradient descent, and reactive updates that propagate changes through all downstream geometry. Users can also write and load custom visualizations that support broadcasting and differentiation.

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.
