Real-Time Fire Simulation Engine
Advanced 3D fire simulation with custom Java/LWJGL engine
Project Overview
I developed a 3D photorealistic, real-time interactive fire simulator with a custom Java/LWJGL engine. I built both the particle and physics engines from scratch, allowing interactive fire objects. To increase realism, I used detailed texture atlases and additive blending. I optimized rendering by batching particles with shared geometry and texture regions, reducing OpenGL calls from 10,000 to just a few per frame. My strong theoretical background from scientific articles was key to the project's success.

Technical Implementation
The system utilizes advanced particle physics simulation combined with optimized rendering techniques. The custom particle engine manages thousands of individual fire particles, each with realistic physics properties including heat-based movement, wind effects, and natural fire spread patterns. The rendering optimization was achieved through intelligent particle batching, where particles with similar properties are grouped together to minimize OpenGL state changes and draw calls.
