MRaster is a very simple C++ library for generating raster images – espeically things like fractals.

It is designed to be easy enough for beginners, but advanced enough for experts. It integrates well into existing code, uses pure C++20, requires no external dependencies, and is quite fast.

Some examples of what can be done with MRaster:

• Mandelbrot Mountains
• Newton Fractal
• Burning Ship
• Multibrot Fractals
• Mandelbrot Iteration Movie
• Tricorn Fractal
• Collatz Fractal
• Tippets Fractal
• Dancing Biomorphs
• Pickover Popcorn
• Mandelbrot Biomorph
• Inverted Mandelbrot
• Mandelbrot Wave
• Peter de Jong Fractal
• Symmetric Fractals
• Chaos Game
• Apollonian Gasket
• Attracting Torus
• Julia Sets
• Circle Art
• Some desktop backgrounds

Versions:

• Version 20.x.x
  • Much more modern API
  • Good unit test coverage
  • Requires a compiler with good C++20 support
  • Still in beta, but pretty solid at this point
• Version 6.x.x
  • Has been published and used since the 1990’s
  • Quite mature
  • Old school API

Version Recommendation: Use 20.x.x unless you have an old creepy compiler that just can’t do C++20.
