[![Build status](https://ci.appveyor.com/api/projects/status/gcp1wxqfhjjk70vg/branch/master?svg=true)](https://ci.appveyor.com/project/Limeth/euclider/branch/master)

A higher-dimensional "non-euclidean" ray tracing prototype written in Rust.

# Installation

1. Install the Rust language via [Rustup](https://www.rustup.rs/)

2. Use nightly rust via `rustup default nightly`

3. Clone this repository and `cd` into it

4. Build with `cargo build --release`

5. Run with `target/release/euclider`

6. Open a scene with `target/release/euclider --scene scenes/3d_room.json`

# Controls

* Mouse wheel - resolution adjustment

* [`Esc`] - exit

## 3D Scenes

* Mouse - camera rotation

* [`W`/`A`/`S`/`D`/`Shift`/`Control`] - camera movement

## 4D Scenes

* Generalized rotations happen in a plane, not around an axis. A plane is given by two axes of the camera. Rotate by holding two buttons bound to the following axes and pressing [`C`/`M`]:

  * [`I`] - x axis

  * [`O`] - Y axis

  * [`K`] - Z axis

  * [`L`] - W axis

* [`W`/`A`/`S`/`D`/`Shift`/`Control`/`Q`/`E`] - camera movement

# Preview

![Fresnel Sphere](preview/preview_3d_fresnel_sphere.png)

A simple sphere displaying Fresnel equations.

![3D Room](preview/preview_3d_room.png)

A scene containing a room with several entities. Listed from left to right:

* a blue sphere with a partially reflective surface;

* a cuboid with an animated perlin noise surface;

* a glass material in the shape of the complement set operation on a cube and a sphere;

* an infinite cylinder passing through the ceiling and the floor

![3D Hallways](preview/preview_3d_hallways.png)

A non-euclidean 3D scene consisting of hallways that either stretch the space inside (left) or shrink it (right).

![4D Cylindric Hypercube Frame](preview/preview_4d_cylinder_frame.png)

A frame of a 4D hypercube made of cylinders as edges. Notice how the rays on the cyan cylinder in the bottom right are reflected to the fourth dimension, revealing more of the frame.
