✨ MirrorVerse ✨

Light ray reflection simulation with 3D rendering.

Built with Rust, using nalgebra for general computation, and glium for graphical rendering.

GUI app built with Flutter

This project is split into four main parts:

1. 📚 The library which contains the core simulation engine, and API for creating new mirrors (mirror_verse).
2. 🏃‍♂️ A program that runs a visualisation of a simulation, from it's JSON representation. (see assets)
3. 🔀 A program that generates simulations randomly and serialises them to JSON files.
4. 🖥️ A Flutter GUI app enabling users to run these tools without the terminal.

GUI

First, make sure you have Rust and Flutter installed on your machine.

🛠️ Compilation

Build the Rust project and move the emitted executables into the Flutter project's assets directory:

Windows

cargo build -r
copy "target\release\generate_random_simulation_3d.exe mirror_verse_ui\assets"
copy "target\release\run_simulation_json_3d.exe mirror_verse_ui\assets"

For Linux/MacOS

cargo build -r && \
cp target/release/generate_random_simulation_3d mirror_verse_ui/assets && \
cp target/release/run_simulation_json_3d mirror_verse_ui/assets

🚀 Running the UI

cd mirror_verse_ui
flutter run --release

CLI

Installing Flutter is not necessary to run/generate simulations from the command line.

🔬 Running a simulation from a JSON file

cargo run --release -p run_sim_json "<path/to/simulation.json>" [max_reflection_count]

Controls

You can use the following controls during the visualisation of a simulation:

• Use the ZQSD keys (or WASD) to move forward, backward, left, and right, respectively.
• Use the space bar to move up and the shift key to move down.
• Click and drag your mouse on the screen to look around, and rotate the camera.
• Use the right/left arrow key to increase/decrease camera movement sensitivity.
• Use the up/down key to increase/decrease physical movement speed.

🔄 Generating a random simulation

cargo run --release -p gen_rand_sim "<path/to/output.json>" [dimension, default=2] [num_mirrors, default=12] [num_rays, default=4]

Contributing

There are many ways to contribute to this project:

• Creating unit tests
• Adding documentation
• Raising an issue on Github for bugfixes or suggestions
• Adding new mirror shapes to the library!

Implementing new Mirror Shapes

First, it is advised to check the documentation, specifically the mirror_verse module, using:

cargo doc --no-deps -p mirror_verse --open

Most mirror implementations, with all of their functionalities, are simple and compact (< 200 sloc), so you can easily browse the already implemented mirrors in the mirror_verse/src/mirror directory, if you need examples.

Note

This project is currently undergoing (yet another hehe) major refactor, in which the core Mirror trait and simulation engine will be seperated into their own crate mirror_verse from other exposed functionalities, that will, then, be seen as extensions/integrations.
