Real-Time Rendering of Gas Phenomena around Single Building

Based on the real-time fluid simulating method in the field of volume and surface rendering, gas phenomena can be rendered by using semi-Lagrange algorithm in three-dimensional volume environment. Combined with the large eddy model of single building, simulation of turbulent wind field around building by simplified eddy model can decrease the complexity, and add details to render. The mirror reflection method of simulation the alternation between building and fluid can avoid the change caused by shape of the building. The rendering and simulation of gas phenomena around building has been accomplished at lower cost.
