1·As its calculation complexity is far more than that of local illumination, there has been yet few satisfying solution which achieves high quality and performance simultaneously.

由于其计算复杂度远远超过了局部光照计算，传统上全局光照明模拟难以同时获得实时的绘制效率和逼真的效果。

2·The basic idea is illuminating the scene with the light probe images. To simplify the design of local illumination model, the bidirectional transmit distribution function is introduced.

在研究基于图像的局部光照模型时，又提出了双向折射率分布函数这一概念，从而简化了局部光照模型的设计。

3·Then the derivation of local illumination source is reported, the near-field electromagnetic scattering characteristics of some electrically large structures are calculated and analyzed.

论文在推导出实现局部照射的激励源的基础上，计算并分析一些电大结构的近场局部照射下的电磁散射特性。

4·In this paper we present an approach for realistic modeling of surface mesostructure and efficient rendering of the associated visual effects under both local and global illumination.

本文我们将讨论表面的细节结构建模技术和几何细节在局部和全局光照下的实时渲染技术。
