在室內裝潢的流程中，設計師和客戶間的溝通是很重要的一環，但由於平面設計圖無法表現出裝潢後的預期結果，容易出現客戶想像中的結果和實際設計有差距，或是設計師無法滿足客戶需求的情況。
而市面上的室內模擬軟體，如草圖專家(Google sketchup)，需要複雜的建模手續及大量計算時間，並且產生的結果是靜態圖片。對於設計師來講是個大量增加工作量的要求，而且因為沒有互動的功能所以溝通的效果有限，對於一般中小型的案例並不符合成本效益，造成雖然有溝通工具，卻礙於成本而不適合使用。
　　本篇論文中提出了一套重建室內場景的流程及讓使用者可以參觀室內的功能。
首先我們使用微軟的體感偵測器(Microsoft Kinect)和相機搜集實際場景的結構、光照資訊及貼圖。接下來提供方便使用者以重建的模型為基礎，快速建立簡單的3D場景並且加上貼圖的介面。
窗戶的光照資訊在計算後以基於物理的渲染方法(Physical based rendering)產生光照圖(Light map)。
　　最後加入遊戲引擎的各種功能，讓使用者可以在場景中自由參觀，並且設計師可以在與客戶的討論中即時更新場景的設計，以達到消除設計師與客戶間溝通障礙的目的。

　　In the procedure of interior design, the communication between the designer and client is very important. But due to that 2D building plans cannot show the expected visual result of the design to the client, misunderstanding easily happens. Although there are commercial softwares available for interior design such as Google SketchUp, they generally need a really complicated modelling process and can only generate snap shots of the design without the ability to interactive walk-through. The complicated modelling process greatly increases the workload for the designers, while the static images can not provide the sense of space to convey the correct design idea. Therefore, it is the goal of this work to develop an interactive interior walkthrough software to visualize the designed with realistic lighting to demonstrate the look of the scene when the work finishes. We proposed a procedure to rebuild interior scenes and let the user be able to browse in it. First we use Microsoft Kinect and camera to collect the geometry, lighting information and texture of the actual scene.
Then we provide an interface for users to build clean and textured scenes based on the rebuilt 3D model. The lighting information of the windows is calculated and rendered with physical based rendering methods to create light maps.
Finally, we add in various functions in the game engine that the user can browse in the scene freely, and the designers can modify the design immediately while discussing with the clients, in order to eliminate the communication barriers between designers and clients.
