Geometry Sketchpad

A Cross-Platform Sketchpad written in Rust using specs

(P.S. The screen shot is from IMO 1959 Problem 5)

How to build/run

Type

$ cargo run --bin geopad-foundation --release

If you are using a Windows machine, you can do

$ cargo run --bin geopad-win --release

We also have an Electron port. You can type

$ cd app/electron
$ npm install
$ npm run build
$ npm start

to run the electron app.

How to use

See interaction scheme.

Code Structure

core folder stores the core libraries of Geometry Sketchpad. core-lib includes only the bare minimal of the systems, components, resources, auxilliary data structures, and events to get the system working. core-ui wraps around core-lib and provide all UI abstraction for the user to interact with the system.

app folder includes the executable applications. Currently we have three applications:

• geopad-foundation: /app/foundation. This one is using PistonWindow for a cross platform experience. It has window_system which does all the window event handling and rendering. It will pass the window events to core-ui's abstracted events. And it will also read from system data to do the rendering
• geopad-win: /app/win. This application is intended to only runnable on Windows platform. It uses native windows API to provide a native experience.
• geopad-electron: /app/electron. This is a port of geopad in Electron platform. (As a side note, this also demonstrates its ability to be ran on web platforms.) It is using Neon as the binding layer, Electron as window driver, PIXI as WebGL renderer. It is, of course, using core-ui as geopad backend.
