中文摘要 | 本研究以做電影流體特效較常見的3D流體模擬軟體包括Maya、RealFlow、Blender、Glu3D for 3ds Max等四套,做純水流的流況模擬。以這四套軟體進行過堰跌水及水躍試驗、圓柱橋墩附近渦流試驗、長方形橋墩實拍等三種流況模擬,與相對影片結果比較分析,並建立經驗參數、效能及精度排序。所有擬真模擬的視角,必須與水工試驗或現場拍攝影片的運鏡吻合,以提供影像的比較分析。在進行驗證的過程及結果,可以確定各軟體模擬的步驟、參數的範圍。成果顯示,雖然各軟體之水流模擬效果有極大的差異,但是大致上水躍現象均有呈現出來,然而停留位置則與實驗有些差異。精度評估結果以RealFlow及Maya表現較佳,檔案儲存及計算效率以Blender及Glu3D for 3ds Max較佳。就水流模擬考慮有模擬床砂時,實用性而言,仍以精度較佳為主,因此建議選擇RealFlow或Maya來模擬。此研究成果可供實際河川模擬水流或模擬河川構造物設置時,提供在視覺展示上之評估。 |
英文摘要 | This study will apply 3D fluid simulation software, more commonly used to do a movie Fluid Effects, including Maya, RealFlow, Blender, and Glu3D for 3ds Max to do the simulation of pure water flow. The 3D fluid simulation software will be used to simulate the falling water after the weir and hydraulic jump, eddy near the cylinder pier in hydraulic laboratory, and surface disturbance near the rectangle pier in field. Finally, the comparative analysis of the hydraulic laboratory and simulation results will be done, and the order of the 3D fluid simulation software according to empirical parameters, performance and accuracy will be established in the future. In all realistic simulation perspective, film camera must work consistent with the operation of the films of hydraulic laboratory, and the simulation results provided a comparative analysis of the image. During the validation process and results, you can determine various software simulation steps, the range of parameters. Flow simulation results of various softwares have great differences, but generally water jump phenomenon has revealed, and the locations of the residence have some differences with experiment data. Generally, the RealFlow and Maya software have better performance in accuracy estimation, the Blender and Glu3D for 3ds Max software have better performance in file size and computing efficiency. Considering accuracy, the RealFlow or Maya software are still better proposed and selected to do the flow simulation with mixed sand in practicality. This results achieved in the future can provide the reference of flow simulation in actual the river, or the impact assessment for the rivers structures setting on the rivers. |
