drzezga / mandelbrot

A tool for exploring and animating the mandelbrot set.

Mandelbrot

App for visualizing the Mandelbrot set and creating videos originally written by Mikołaj Hudko in middle school while learning java. Later fixed up for a university course.

Prerequisites

• Java 1.8
• Maven
• ffmpeg (best copied into the project root dir)

Controls when focusing the preview pane

• WASD to move the preview,
• R to zoom in, F to zoom out,
• Q to rerender,
• X to increase iteration (accuracy of calculation), Z to decrease,
• Y to swap between rendering the Mandelbrot and Julia sets

Image tab

Contains resolution presets and image manipulation options

Render settings tab

Contains settings for:

• Render engine:
  • Mandelbrot set with float precision
  • Mandelbrot set with double precision
  • Julia set with double precision
  • Color palette display
• Crosshair display
• Image supersampling.
• Coloring algorithm (the Smooth option doesn't work well with Julia sets) and color palette

Position tab

Precise values of the parameters used for rendering. All can be set manually

Animation tab

This tab is used for creating animations with ffmpeg. Create camera keyframes on the timeline and edit by right clicking. Move them by dragging and resize the timeline by scrolling. You can set the current position and parameters by clicking Set and preview a keyframe by clicking Go.
