Firefly

• Implementing an interactive particle system with OpenGL and C++.
• The particle system simulate a swarm of fireflies attracted by a point light, while every individual of them is doing some kind of random motion.
• Using modern Core-Profile mode of OpenGL.

Details

• The player will control a flying camera in a 3D simple scene(mainly composed of a skybox and a mountain-like mesh), and all the fireflies will be attracted by the point where the camera is located.
• Two scenes are provided, one low poly and another realistic.
• At most 400 fireflies are supported and each of them can emit 200 second-level particles.
• Every single firefly act as a light source, which will illuminate the mountain-like mesh. Some optimizations have been done for better performance.
• Bloom effect is implemented to make fireflies shiny.
