dc.description.abstract置換貼圖是一個以純量高度函數來表示模型表面上的幾何細節的技術。結合置換貼圖的顯像技術在近幾年來因為繪圖硬體的效能提升,已經能夠達到即時顯像的要求。而基於這些現有的結合置換貼圖的即時顯像技術,我們發展出一個新的化簡模型的機制,可以產生一個新的網格模型表示法,以一個化簡過後的基底網格模型結合一張置換貼圖來表示一個以大量的多邊形去建構幾何細節的原始模型。原始模型的整體形狀被轉化成化簡後的基底網格模型,而在原始模型表面上的那些幾何細節資料則以置換貼圖的型態保存下來。於是我們可以利用結合置換貼圖的即時顯像技術去繪製化簡過後,多邊型數量較少的的基底網格模型,並且加上置換貼圖來重現原始模型的顯像效果。zh_TW
dc.description.abstractDisplacement mapping is an technology to represent the surface details as a scaler height-field function. Thanks to the advancement of graphic hardware, rendering with displacement mapping came to real-time in recent years. Based on the new rendering methods for displacement mapping we develop a new simplification framework to combine the coarse base mesh with a displacement map to be a new mesh representation. The global shape of the original mesh is approximated by the coarse base mesh and the detail componenets are captured by the displacement map. And this mesh representation can be rendered in real-time performance using the per-pixel ray-casting methods for displacement mappingen_US
