Mandelbrot Set Viewer Written in C++

Prerequisites

G++

• You will need the g++ compiler to compile the project using the makefile
• If you have another compiler, you can compile manually (just look at the makefile)

wxWidgets

• You will need wxWidgets installed on your system with a working wx-config for compilation to work
• wxWidgets can be found here: https://www.wxwidgets.org/, or installed with packages managers (e.g. $ brew install wxwidgets or # pacman -S wxwidgets)

OpenCL

• If you care to try the OpenCL version of the program (by using make opencl), you will need a functional installation of OpenCL

Permissions

(mac) You will have to allow a shit ton of libs to run by going to system preferences/security & privacy/general

Usage

After compiling with make, the binary will be in bin/mandelbrot

make will compile a basic version of the program. It is multithreaded but written in standard c++.

make opencl will compile a different (faster) version. It requires a functional OpenCL installation and is not guaranteed to work. This version can be ran on either a GPU or CPU. If it works but does not run on the right device, you can try to edit the code in openclStuff.c where the device is chosen (it is chosen from an array, with the default device being at index 0. You can try other indices.

Keybindings

• Enter zooms in (4x)
• Arrow keys or WASD move the target cursor (the place where it will zoom in)
  • Pressing shift while using movement keys makes the cursor move faster
• Escape zooms out
• Pressing I increases the current number of iterations and redraws
• Pressing K will (randomly) change a constant within the code that affects the coloring
• Pressinc C will (randomly) change the hue of the image
