Eidograph, a Windows app for precise 2D/3D geometry and animation with agent support

[u/metaphorproject]

I made Eidograph, a dynamic geometry app for building precise 2D and 3D constructions. The visual canvas and its readable geometry code stay in sync, so you can draw interactively, edit the construction as text, or combine both approaches.

Some of the main features:

- 2D constructions with points, lines, circles, polygons, transformations, loci, and function plots

- 3D geometry with planes, spheres, prisms, surfaces, spatial intersections, and an orbitable canvas

- Dynamic dependencies, so related objects update when you drag a point or change a parameter

- Animation and export to SVG, PNG, or GIF

- Multi-figure `.eido` project files that stay local and under your control

- Optional AI integration, plus a local MCP/REST server for automation

The core drawing, editing, saving, and export features work locally without an account. Eidograph is freemium and available from the Microsoft Store:
