在今日電腦得以進行快速運算的條件下,虛擬軟體的應用已廣泛成為多種專業,如飛機、土木結構、氣候預測、照明設計,做設計的工具。除了有些資料庫龐大的軟體,需要付費購買使用權,時下也有許多免費產品,供各行各業選用。也因此,這類照明設計軟體,除了經常改版,提升實用性,已經成為世界各國照明界廣泛應用的工具。只不過,這似乎不受國內設計界普遍應用。為了掌握照明軟體的工學性藝術性與實用性,本研究以五種3D模型匯入兩款免費軟體:DIALux EVO及Relux中,執行多種照明考量的運算,以檢視與比較其藝術性效果,以及工學性參數的周全性。納入其中的空間種類包括室內、建築外觀、戶外景觀、網球場、籃球場、道路。場所差異的應用,得以檢視軟體操作界面、3D模型及燈具整合、不同照明規範是否滿足等工作之便利性。結果得知,DAILux EVO該軟體可充分滿足上述場所的照明工學參數計算,更能夠藉其光跡追蹤之功能,產出高逼真度的照明情境,參數計算與模擬效果,值得國內空間環境設計界參考使用。
On the basis of fast computing hardware, vitural simulation is widely employed in various professions, such as plane design, structural design, weather forcasting. Some of these software that equipped with huge data base, entails a lot of usage fees, some others are free of charge. Even though lighting software are constantly under revision to escalate usability and acceptability, it does not seem to be the case in Taiwan. To examine the usability of such software, this study conducted a series of test run of diverse spatial designs on one of the free download software: DIALux EVO. The chosen spaces include interior space, architectural façade, outdoor landscape, tennis court, baseketball court, and roadway lightings. In this way, various concerns of usability may be cross examined, namely, ease of interface operation, ease of 3D model construction, ease of plotting luminaire in 3D models, and ease of comparing calculation results to varisous lighting standards. Through which, it can be concluded, compared to that of other lighting programs, the tested lighting program is capapble of executing photoaccurate lighting engineering calculation and acoomplishing photorelistic lighting effects, and worthwhile promoting to the design community in Taiwan.
