臺灣博碩士論文加值系統

　　在傳統服裝設計的過程中，從概念設計至樣衣製作一直都是高成本代價的設計製作流程，所以本論文提出利用電腦輔助服裝設計的概念，以縮短設計開發的時間與降低設計製作的成本。本論文研究主要分為兩個部分，『2D裁片的繪製』與『3D虛擬服裝的模擬呈現』。在2D裁片的繪製上，主要利用B-spline曲線達到繪製各種直線與曲線的變化要求，並根據質點彈簧模型產生符合布料特性的裁片。在3D虛擬服裝的模擬過程中，主要的問題為服裝布料的真實性與碰撞運算的效率，透過利用近似隱含法、材質貼圖與光學法則達到布料模擬的真實性，並利用向量運算與體素法增加模擬過程中碰撞運算的效率。最後，以JAVA語言實作一程式系統，呈現本論文中理論研究的結果，以達到電腦輔助服裝設計的研究目標。

　　Traditionally, the clothing design is always completed with a high cost from idea sketch to sampling. Thus, a computer-aided method for clothing design is proposed in this paper to reduce the required time and cost. This method is divided into two parts. One is the 2D patterning, and the other is the 3D visual clothing. In 2D patterning, we use the B-spline curves to present various lines and curves, and to create clothing patterns based on the Mass-spring model. As for 3D visual clothing simulations, the primary problems are the sense of the reality of fabric and the efficiency for collision operation. For these reasons, we simulate the sense of reality of the fabric using an approximate implicit integration and the texture mapping technique. Besides, we improve the efficiency for collision operation using the vector and voxel model. Finally, the programs for this simulation system are written with Java languages to present the results of our study and to achieve the goal of computer-aided clothing design.
