Method and Apparatus for Providing Fluid Simulation Using Particles

Realistic 3D Game Engine Smoke Particle Implementation Using FDS Fire Analysis Data

This technology performs FDS (Fire Dynamics Simulator) fire analysis on structural and architectural objects, detects movement frame-by-frame from the resulting video to extract smoke density values over time, and converts them into game engine scripts to render smoke particles in a 3D environment.

Standard game engines struggle to calculate fluid-dynamic smoke flow in real-time due to computing resource limitations. Existing methods that generate and dissipate smoke particles through real-time coordinate calculations are resource-intensive and complex, often causing particles to vanish too quickly, making the smoke look like steam.

By offloading heavy fluid calculations to FDS and passing only frame-specific density values and particle box lines to the game engine, this technology reduces real-time load while accurately simulating smoke diffusion. It realistically depicts smoke flow within complex building structures, making it ideal for fire evacuation training, VR firefighting education, and disaster scenario games by providing immersive, physics-based training environments.

Key Features:

• Performing FDS fire simulations using preset parameters for multiple objects including one or more entities
• Detecting smoke by identifying pixel movement across continuous frames of FDS data and tracking the movement of the detected smoke
• Extracting regional smoke density values from frame-by-frame movement data, storing them over time, and applying them to a 3D game engine via game development tool scripts
• Classifying smoke diffusion by preset spatial types and modeling particle box lines that rotate around the ignition point for simulation within the game engine
