⚡ Rayden - Simple Python Ray Tracing

## Features

- **Geometry**: Sphere, Plane, Triangle, Torus

- **Light**: Point, Area (rectangle)

- **Material**: Diffuse, Specular, Mirror, Glass, Checkerboard, Procedural Textures, Normal Map

- **Distributed Ray Tracing**: samples per pixel and shadow

- **Depth of Field**: depth and dispersion setup

- Scene description from JSON file

- Using *numpy* and *multiprocessing*

- FQS - Fast Quartic and Cubic solver (https://github.com/NKrvavica/fqs) for computing roots of a quartic equation (torus intersection)

- 2D, 3D and 4D Simplex Noise functions from https://github.com/dangillet/space_tactical/blob/master/simplexnoise.py

- Colour (https://github.com/vaab/colour) for named colors

## Usage

```

                        Scene description file

  --output OUTPUT, -o OUTPUT

                        Output file

  --samplesPerPixel SPIXEL, -sp SPIXEL

                        Samples per pixel

  --samplesPerShadow SSHADOW, -ss SSHADOW

                        Samples per shadow
