dc.description.abstract對於非真空狀態下的整體照明度演算法仍有一些問題值得探討。在本論文 中,我們提出架構於蒙地卡羅方法的二階段光線追蹤法去模擬光線與空氣 中介質的作用現象,我們使用不同密度小立方體(voxel)來建構這些介 質。第一階段,我們擴充蒙地卡羅幅射熱傳導法處理任意密度的介質,同 時考慮光線的衰減程度。第二階段,則使用體積著色法產生非真空環境下 的逼真影像。 In global illumination, there are still few works discussed the effects caused by participating media. In this thesis we propose a two-pass ray tracing algorithm based on the Monte Carlo techinique to simulate the interactions between light and the media within volume. These participating media are modeled as voxels with different density. The volume density function is defined by noise and turbulent function. In the first pass, extended Monte Carlo radiosity is used to inculde arbitrary voulme density and considers the light attenuation. During the second pass, the volume rendering algorithm is applied which take accounts viewing rays attenuation in order to generate a realistic image in presence with participaing media.zh_TW
