| dc.description.abstract | 我們在這篇論文中要提出一套系統，他可以讓我們在固定的光源環境下，對多層次半透明物體作材質編輯。這套系統允許使用者
去改變一些參數，像是散射係數與吸收係數，然後可以即時地看到改變後的樣子，並且包含多次散射與單次散射。我們使用PRT技術來事先計算 出每個頂點上的轉移函數，然後再藉著係數與轉移函數的內積，來計算每個頂點的顏色。我們利用GPU的性能來加速，以達到即時的繪製效果。 | zh_TW |
| dc.description.abstract | This paper present a system to do real-time multi-layer translucent material editing under static lighting with multiple scattering and single scattering.
This system allow user to change parameters of BSSRDF function like $sigma_s, sigma_a$, and have real-time rendering feedback. We use PRT(precomputed radiance transfer) technique to precompute the transport function of each vertex and compute color of each vertex by dot product of coefficients and transport functions. We use GPU to achieve real-time rendering performance. | en |
