R0ger Posted July 2, 2020 Share Posted July 2, 2020 (edited) New program for rendering Mandelbrot set named Fractari was released as part of FLOP 65: http://flop.atariportal.cz/index.en.php It uses scanline GFX mode to get 8 colors, and fast square algorithm for 16, 24 and 32 bits. It then selects the best variant based on zoom. The goal was to create the fastest possible Mandelbrot set generator. Included presets render from few minutes to 1 hour. The basic overview of the Mandelbrot set takes 24 seconds, with preview in Antic D mode. It renders the image in 4 phases, first phase only renders every 4th pixel. This gives you quick preview and you can continue zooming without waiting for the rest, and it's also used to estimate where more calculation is needed, and where the color of the other pixels can be just assumed. After the image is rendered, it allows relatively quick change of visualization parameters, things like palette and color scaling, without repeating the calculation. Other features include: - 3 different DMA modes for previewing the image, from fastest to best looking - preset locations to render nice images even if you can't navigate Mandelbrot set at all - party mode, which just goes through the presets one by one - and more ! I consider this as something of a version 1.0, and I already have tons of ideas for 2.0. Things like built-in help, animation using extended memory and disk operations. Please read detailed description in stand-alone article in FLOP 65. The program supports both PAL and NTSC, and while not tested, it should also work on better CPUs. Nice video about exploring Mandelbrot set, which actually inspired me to make this: https://www.youtube.com/watch?v=riLFpb-PcLs Few images from the program: Edited July 2, 2020 by R0ger 33 5 Quote Link to comment Share on other sites More sharing options...
