越來越多的三維技術使用在生活中的各個層面。其中最直接呈現在眾人眼前的，除了三維模型本身的細緻度外，另一個就是貼圖的部份。三維模型的貼圖過程除了平面繪圖一般的繪製過程，還需考慮由二維轉為三維所造成的失真，是項繁複且精密的工作。

本論文提供一個自動化的貼圖流程，使用者在三維模型上描繪出自己所希望的貼圖流向之後，由程式完成其餘的貼圖步驟，減少使用者需要介入操作重複步驟的時間。並且對於重複性質高且結構性較強的貼圖，有額外的方法作為補強。

More and more 3D technique are used in our life. The quality of texture and model are the most obvious for visibility.
We introduce a texture method that automatic synthesis the texture with high repeated and strong structural according to the vector field on 3D surface. User can simple sketch the direction line they want on the surface, and program generates the vector field for the whole model, finally, synthesis the texture form the vector field. This method save the time and reduce the repeated step for user.
