查询词典 reflectance

Based on recent based on precomputed radiance transfer techniques, this paper proposes a novel method for real-time editing object material under complex environment lighting. First, we precompute the visibility for each vertex as a precomputation stage; Next, at rendering stage, we on-the-fly compute bidirectional reflectance distribution function. Finally, we render the object material by looking up visibility of each vertex.

为了在环境光下对模型表面的材质进行实时编辑，提出一种基于预计算辐射传输的算法：首先预计算环境光相对于模型表面每一个顶点的可见性；然后在绘制时实时计算物体表面的双向反射分布函数；最后通过查找环境光相对于模型表面每一个顶点的可见性，快速绘制出物体表面材质。

In this study, we used poly L-latcide, poly DL-latcide-co-glycolide 75:25 (PLGA7525) and poly DL-latcide-co-glycolide 50:50 (PLGA5050) during citric acid inducing ammonium bicarbonate gas forming process to form porous polymer film, and rolled the porous polymer film to make nerve conduits with pores and multi-layered. Electron Spectroscopy for Chemical Analyzer and Attenuated Total Reflectance – Fourier-Transform Infrared Spectrometer were employed for determining elements' functionabilities and chemical compounds. Charge Coupled Device camera and Scanning Electron Microscope were employed for macroscopic and microscopic morphologies and structural observation. Differential Scanning Calorimetry was employed for measuring glass-transition temperature. Nano-indentation system was employed for measuring elastic modulus and hardness. Biodegradation and water absorption ratios were measured to analyze their chemical properties and SEM was employed for microscopic morphology of the tested nerve conduit.
