隨著電腦技術的不斷發展，加速了設計行業間的合作，而3D動畫設計與現代建築設計結合在一起，產生了建築動畫，建築動畫是將動畫設計與建築設計結合起來，通過3D動畫來展示建築物的內部空間和外部空間，以及各個不同的視覺關係，達到一種較完整的立體空間效果，解決了過去傳統的2D的傳達方式，同時也提高了設計工作的效率。在商業領域，3D建築動畫已獲得了十分喜人的成績，畫面愈加真實，與自然後環境更為接近，但不可否認的設計師在製作動畫時，對建築動畫設計製作上難度過大且複雜不易學習，都是存在許久的問題之一。3D動畫是建築工程中常用的設計表現方法，在方案設計的投標階段起就可開始應用，創作研究中以臺中市水湳經貿園區水資源回收中心為例，透過了SketchUp與Twinmotion的結合應用過程中，提出了3D動畫的簡化流程與方法，在實際案例中有效率地製作出3D可視化工程，節省了人力與時間，進而降低製作成本。進而未來可套用在未來景觀設計、虛擬實境、旅遊開發.......等類型的3D製作方案中。研究中除了3D可視化方案外，也結合空拍UAV成型技術及工程實地縮時攝影，將2014年工程開工至2017峻工期間的空拍正攝圖彙整成寶貴的工程記錄影片，可供市政府在城市行銷與工程檢討資料使用。整個研究中產出的3D動畫突破一般只利用3D可視化來表達，應用了數位整合的方法來詮釋整個工程動畫，實地攝影記錄及3D各個水資源處理流程的物件解說，讓工程3D動畫有不同的表達方式。

The continuous development of computer technology has accelerated the cooperation between design industries. The combination of 3D animation design and modern architectural design have initiated architectural animation. Architectural animation combines animation design and architectural design to display internal and external space of the architecture and achieve more complete 3D space effect through various visual relationships. That provides a better solution than traditional 2D display and enhance the effectiveness of design works.
As for business application, 3D architectural animation has very compelling achievements with several advantages, including more realistic image and more close to natural environment. However, it cannot be denied that a long-existed disadvantage of 3D architectural animation is: the design and creation of it is very difficult and complicated for designers to learn.

3D animation is a commonly used design and display tool in construction projects, and it can be used since the bidding stage of a project. The study take Taichung City Shuinan Water Recycling Center Construction Project as example to propose a simpler process and methodology for 3D animation through the combination of SketchUp and Twinmotion applications. In the actual case, 3D visualization project can be built up efficiently, saving labor and time and reducing production costs as a result. The simplified process can be applied in various 3D design projects in the future, such as landscape design, virtual reality, tourism development, etc.

In this study, in addition to 3D visualization project, we also combine aerial UAV photography technology and real-time time-lapse photography to summarize UAV pictures from 2014 to 2017 (from the start to the completion of the project) to a valuable project record film for Taichung City to apply for urban marketing and project review. The innovation of the 3D animation output of the study is: in most cases, only 3D visualization technology is used in 3D animation, but in the study we apply digital integration method for the expression of the project, including real-time photography record and the narration of steps in the water resource treatment process, to explore innovative expression method for engineering 3D animation.
