This is a Particle System Demo I made for OpenGL. This code was also used for the laboratory lessons of Computer Graphics in University of Patras while I was teaching there and was created to enrich the course.
This particle system can accept any geometry as the basis for the particle emitter, supports complete 6-DOF control of each particle, as well as transparency (although at a big performance hit).
The architecture consists of an interface class which is intended to be used as a basis for creation of a concrete particle emitter class. The interface completely encapsulates all the ugly OpenGL code and makes the manipulation of particles completely OpenGL-code free.
The source code in the lab08 folder also serves as a demo for demonstrating two example emitters (a FountainEmitter and an OrbitEmitter) and for comparing performances with a non-instance based rendering to showcase its advantages for particle rendering.
The project is completely protable, so only the absolute basics are needed:
- CMake
- C++ Compiler (preferably supporting C++17 for some features to be enabled)
- OpenGL support (barely worth mentioning)
