視線相關的多邊形簡化演算法

Abstract

正因為越來越精密的幾何模型在今日是非常容易產生而獲得，所以在即時系統的環境中，越來越複雜的幾何模型已成為處理上的一大負擔，傳統的多層次精細度處理的方式有許多先天條件上的限制，因此我們提出了視覺相關的改良方法來突破這些限制，當觀看的視覺環境因素成為必須考慮的要點時，場景中見不到的部分將會再度被簡化以縮減描繪所需要的時間。進而更可以達成即時系統的要求。

Recently, more and more complex models are easily often used since they are easily to create. However, it is still difficult to handle the complex models in real-time environment. Traditional level of details technology is limited by the condition of view-independent. In this thesis, a view-dependent level of details technology is proposed. By considering the conditions of viewing, the mesh that can not be seen by the viewer will be reduced that can decrease the rendering time, and achieve the requirement of real-time system.
