Multi-threaded SFML + ImGui Mandelbrot

A multi-threaded C++ Mandelbrot renderer using SFML + ImGui running at a constant 60 FPS for Windows, Mac and Linux.

This is a graphical, interactive version of my Mandelbrot Comparison project which implements the same Mandelbrot algorithm in 5 different languages (C, C++, Python2/3, PHP and Swift). The colorization of the images is done by using a histogram based smooth coloring method.

Build

Default build instructions for CMake and Vcpkg. These examples assume that Vcpkg is installed in your home directory. Adjust the paths if necessary.

Vcpkg toolchain

Pass your Vcpkg toolchain file via CMAKE_TOOLCHAIN_FILE, for example on Windows:
-DCMAKE_TOOLCHAIN_FILE=%HOMEPATH%\vcpkg\scripts\buildsystems\vcpkg.cmake

Or on Unix systems:
-DCMAKE_TOOLCHAIN_FILE=$HOME/vcpkg/scripts/buildsystems/vcpkg.cmake

Linux + Mac

$ mkdir build
$ cd build
$ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=$HOME/vcpkg/scripts/buildsystems/vcpkg.cmake ..
$ ninja
$ cd ..
$ ./build/src/mandelbrot

Windows

$ mkdir build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=%HOMEPATH%\vcpkg\scripts\buildsystems\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows ..
$ cmake --build . --config Release
$ cd ..
$ .\build\src\Release\mandelbrot.exe
