Euclider

Euclider is a higher-dimensional "non-euclidean" ray tracing prototype written in Rust. This project explores ray tracing in both three-dimensional and four-dimensional spaces, offering a unique perspective on graphics rendering.

Project Introduction

Euclider leverages Rust's capabilities to create a prototype that handles ray tracing in higher dimensions. It supports both 3D and 4D scenes, with various controls for navigating and interacting with the environments. The project is dual-licensed under the MIT License and the UNLICENSE.

Features

• Higher-Dimensional Ray Tracing: Supports both 3D and 4D ray tracing.
• Customizable Scenes: Load scenes from JSON files to explore different environments.
• Interactive Controls: Navigate scenes using intuitive mouse and keyboard controls.

Installation

1. Install Rust: Ensure Rust is installed via Rustup.
2. Use Nightly Rust: Set the default toolchain to nightly using rustup default nightly.
3. Clone the Repository: Clone the Euclider repository and navigate into the directory.
4. Build the Project: Compile the project with cargo build --release.
5. Run Euclider: Execute the binary with target/release/euclider.
6. Open a Scene: Load a scene file using target/release/euclider --scene scenes/3d_room.json.

Controls

General Controls

• Mouse Wheel: Adjust resolution.
• [Esc]: Exit the application.

3D Scene Controls

• Mouse: Rotate the camera.
• [W/A/S/D/Shift/Control]: Move the camera.

4D Scene Controls

• Generalized Rotations: Rotate by holding two buttons corresponding to the camera axes and pressing [C/M]:
  • [I]: x axis
  • [O]: y axis
  • [K]: z axis
  • [L]: w axis
• Camera Movement: Move the camera with [W/A/S/D/Shift/Control/Q/E].

3D Room

A room with several entities:

• A blue sphere with a partially reflective surface.
• A cuboid with an animated perlin noise surface.
• A glass material in the shape of a cube and sphere complement set.
• An infinite cylinder passing through the ceiling and floor.
