relighting

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

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。

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

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。

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.

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。

3D Surface Textures Synthesis and Relighting in the GPU

三维表面纹理合成及重光照的GPU实现

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

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。

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

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。

Step 2: The Relighting Trick

第二步：重新燃烧的妙招

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

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 purpose of the competition is to have participants or teams to smoke a pipe for the longest possible period of time without relighting it and to determine who does this longest.

本竞赛，旨在组织参赛者或参赛队，在不重新点火的条件下，比赛吸烟斗之时长。
