摘要：Smoke simulation is an interesting topic in simulation fluid dynamics and graphics area. Stack Effect Fire model was happened in fire of High Rise building. Simulation this fire model and smoke scene is one of the most challenging tasks in fluid dynamics of computer graphics area. In this paper proposed Smoke simulation rendering is based on game engine of particle system. But common game engine don’t have stack effect model and compute coordinate position algorithm. Recently proposed method based on FDS’s (Fire Dynamic Simulation) result Excel file which improves Unity 3D game engine for stake effective fire model and smoke boundaries. Using Excel file coordinates to improve Unity 3D game engine particle system, and changes the original game engine particle system, over the coordinates of particles moving location, boundary and fire model stake effect look like real world fire model. Recently game engine computer graphic researcher usually control computing resources focused on smoke visualization skip fire effect and physically problem. In this paper, need focused on smoke location boundary and fire model stake effect. The proposed method can change smoke and fire model of stack effect and particles more accurately and efficiently than other, rendering is implemented by making smoke particles and physically effect. After putting the coordinate form FDS into Unity3D game engine Experiment performance result shows particles more look like reality, and gives neutrality and reality to user's view. This algorithm problem is from simulation high rise building mesh with loading time need more computer resource, and need to change some effect in Unity 3D game asset.
