⚡ 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
