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
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。
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。
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。
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。
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。
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. 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。
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。
