| dc.description.abstract | 本論文提出一個可用於動態場景、視角、光源的混合式光跡追蹤成
像法，混合使用區域著色法(Local Shading)和光跡追蹤法。過去雖然有許多相關的方法被提出，然而大多只呈現部分成像效果而已，而且硬 體要求也比較高。我們選擇使用區域著色法和光跡追蹤法各自的優點 並利用圖形處理器(GPU)和多核心處理器(CPU)以平行計算方式，期望 在目前一般的硬體規格下能計算出柔和陰影、反射、折射，以及間接 光照等效果，並且加速至互動速率下呈現。 | zh_TW |
| dc.description.abstract | This thesis presents a hybrid ray tracing renderer for fully dynamic scene, camera, and light sources. Many Ray tracing algorithms have been proposed to product most visual effects but these methods are still hard to render at interactive rate on common hardwares. We combined raytracing with local shading methods and used parallel computing on GPUs and CPUs to product most visual effects like soft shadow, reflection, refraction, indirect lighting effects at interactive rate on most common hardware today. | en |
