In this paper, we made a short introduction of the history of photo-realistic rendering, and compared the PRT ( Precomputed Radiance Transfer ) technique with traditional rendering techniques. 本文首先简单介绍了真实感图形绘制技术的发展历史,并比较了传统绘制技术和新近被提出的预计算辐射亮度传输的绘制技术的差异。
The main components of pre-computed radiance transfer technique are to explore suitable pre-computation and sampling strategy, to reduce the amount of sampling data, and to support fast rendering. 预计算的光辐射传输函数技术的关键问题是,采用适当的浙江大学博士学位论文预计算采样的模式,减少采样数据量,并支持快速绘制。
