ParticleSimulator

SDL + OpenGL particle simulator in C++ featuring ImGui widgets

This project is an adaptation of the particle simulator code from the free Udemy course C++ Tutorial for Complete Beginners by John Purcell. The current implementation adds the possibility to interactively modify various simulation parameters (such as number of particles, particle color, color cycling speed, particle radius, spin, and speed) through Dear ImGui widgets.

Dependencies

• cmake
• make
• g++
• libsdl2-dev
• OpenGL 3

Building the particle simulator

First, clone this repository:

git clone https://github.com/alexandra-zaharia/ParticleSimulator.git

Create the directory where the executable will be built and cd into it:

cd ParticleSimulator
mkdir build
cd build

Now run cmake and make:

cmake ..
make

Run the particle simulator from the build directory:

./ParticleSimulator

Motivation

The motivation to build this project is purely personal: although the particle simulator does not "do" anything useful per se, it allowed me to dive (yet again) into C++, to reflect upon object oriented design, to use graphical frameworks, and to try out a C++ library for GUI creation.

TODO

• Add box blur effect
• Add widget for blur radius
