三维表面纹理合成及重光照的GPU实现

3D Surface Textures Synthesis and Relighting in the GPU

重光照（Relighting）技术就是对目标对象重新打光的过程，其作为增强现实的一个重要手段而成为人们的研究热点。

Essence of relighting technology is the process of relighting the target object , as an important means of augmented reality of the graphics has been extensive researched and applied .

并且基于朗伯模型将生成结果，应用到三维纹理重光照中。

And the results based on Lambertian model will be applied to three-dimensional texture re-lighting .

而基于图像的重光照技术是其中一个重要方向，也是近年来图形技术研究中的一个热点。

Image-based relighting is an important research field in it and also a hot point in graphics .

同时本文也以基于谐波图片的重光照技术进行了简单的应用。

At the same time , we use the relighting based on harmonic images in a simple application .

基于图像的重光照需要大量采样图像，而且难于重建表面光照的高频分量。

Image-based relighting requires many samples , and hard to rebuild the high-frequency components of the light on the surface .

他曾受日本颁授的勋二瑞宝重光章，外国人获此殊荣，戴明为最高。

He was awarded the order of the sacred treasure , second class , the highest Japanese award ever given to foreigners .

其研究内容可分为逆向绘制、基于图像的重光照和对材质样本的光照采样等三类方法。

The main research can divide into three catalogues : Reverse drawing , Image-based relighting , Light sampling based on material samples .

真实光源的获取及重光照是计算机图形学和计算机视觉的两个重要研究领域。

The real light source acquisition and relighting technology are two important areas of research in the computer graphics and computer vision .

重光后，香港政府及获授权的本地银行恢复发行本地的货币。

The issue of local currency was however resumed by the Hong Kong government and the authorized local banks after the liberation .

逆向求解光照技术及根据其发展而来的重光照技术等在虚拟现实、增强现实、图像融合、人脸识别等众多领域具有广泛的应用前景。

Inverse lighting and re-lighting techniques can be used in many applications , for examples , virtual reality , augmented reality , image composition and face recognition .

本文从基于图像的重光照算法入手，由于要渲染出真实光源的特殊光照性质及纹理，因此必须将光源看作近域光源。

Because we want to render the property and texture of the real light source , the light source must be seen as the near-field light source .

逆向绘制方法反求物体的材质参数，但难于实现实时的全局重光照绘制，而且对光照条件要求严格。

Reverse drawing can compute the material parameters of the object , but hard to achieving real time rendering of the global illumination . It also requires strict light condition .

重光照技术主要经过采集数据、处理数据以及合成运算三个步骤，根据采集数据和处理数据的方法的不同有不同的研究的方向。

There are three main steps in relighting : data-capturing , data-dealing and synthesis computation . Based on different methods to capture and deal with data there are different research directions .

而西方风景画遵循的则是真实的色彩观，重光谱色，讲明暗阴影对照等。

While the Western landscape painting follows the real color view , putting the emphasis on the spectral color , and advocating the comparison of light and dark shadow and so on .

该模型适用于强反馈以及多重光反馈下的自混合干涉效应和弱光反馈水平的情况，也可以转化到其它文献所报道的模型。

This model was the same with conditions of strong feedback ( also strong feedback with multiple reflections ) and weak feedback . And this model could be transformed to other reported models .
