Mandelbrot

This project made for visualization of mandelbrot set.

Installing

Project supported on Linux only.
Mandelbrot requires SFML graphics library, AVX2 technology and OpenMP.
To start clone repository and make project: > make main

Features

• 2 modes: video-mode for viewing set in high FPS and screen-mode for making images of set in high quality.
• To speed up used parallel programming(OpenMP) and AVX.
• The ability to create configs to save the patterns of the set.
• The ability to control FPS.

Usage

Config

You can make config.cfg file and add coordinates, scale, screen resolution and quality of set.
Here is example of standard setup:

WINDOW_WIDTH:   800
WINDOW_HEIGHT:  450
COLOR_WIDTH:    27
COLOR_OFFSET:   81
MAX_ITERATIONS: 256
MAX_RADIUS^2:                     40
OFFSET_X:                          0
OFFSET_Y:                          0
SCALE:                          0.01

Program finds first occurrence of keyword (OFFSET_X, COLOR_OFFSET, WINDOW_WIDTH, etc.) and makes setup with number after keyword. If in file there's no such keyword, program use standard setup.
Config settings:

• COLOR_WIDTH and COLOR_OFFSET are used for colorization.
• MAX_ITERATIONS and MAX_RADIUS^2 are used for quality of set.
• OFFSET_X and OFFSET_Y show center of set.

Program launch

• > ./mandelbrot launch video-mode with parameters:
• > ./mandelbrot screen launch screen-mode which makes one image with parameters from config.cfg and saves it.

Video-mode Controlling

• E - exit the program
• LAlt - zoom out
• X - zoom in
• Left - move left
• Right - move right
• Up - move up
• Down - move down
• F - enable/disable FPS
• L - load this position and make new config (save to custom_configes.cfg)

Example

This is how I used this program in total:

1. Find nice pattern with standard config in video-mode
2. Load this config with name of pattern
3. Change pattern config's settings: Iterations 20000, radius 100, width 1920, height 1080.
4. Launch screen-mode
5. Done

In file custom_configes.cfg you can find some configes for nice patterns. In folder images you can find images of this patterns.
