light mapping meaning in English
光影贴图。目前的游戏最常用的是光影贴图，以光纹理的形式把光源应用于三角形。
Examples
- The basic idea of model - based light map is to explore the captured facial reflection model and recovering light map from a single picture
基于模型的光照图的基本思想是利用已经获得的人脸反光模型，从单张人脸照片恢复出人脸所在场景的光照图。 - This algorithm needs a height map and the camera ' s information . light map is used to adjust the surface ' s brightness that avoids some noise effect due to the phong lighting mode . all these strategies are let to the effort to improve the render application ' s reality
采用lod技术,当绘制较远处的物体时使用简化的模型,并采用粗略的纹理采样技术,绘制近处的物体时使用详细的模型,并采用线性采样,这种技术符合人们观察物体的习惯,大大缩小了计算量。 - This technique can find applications in image composition and some facial animation system . for a picture with a face , mbl can recover the light map of the face and then a new face or any other synthetic object can be rendered into the scene smoothly in terms of illumination
这个技术可以应用到照片合成中去，对一张带人脸的照片，恢复出其光照图，然后可以利用恢复的光照图把新的人脸或其它物体合成到这张照片中去，这样可以缓和照片合成中的光照不协调问题。 - In the first part , the reflection model of a particular face is captured firstly and structured as a collection of reflection functions . and then , with the help of luxmaster , the rendering tool , where a light map represents a lighting condition , a variety of faces with different expression are rendered under changing illumination
在不同表情不同光照下的真实感人脸绘制部分，首先对人脸反光模型进行采样，并把采样数据组织成反光函数，然后应用工具luxmaster生成不同光照下的各种表情的真实感绘制，其中光照条件用光照图来表示。 - Finally , this thesis introduces the model - based light map ( mbl ) technique and its basic idea and framework . in order to capture the facial reflection model efficiently , a 3d light stage with 1 . 5 - meter radius is custom - built . a basic recovering algorithm based on conjunction gradient method is described and some results are provided
先提出了基于模型的光照图技术的基本思想和框架，然后介绍自行设计建造的一个半径为1 . 5米的三维光照架，和一个基于共轭梯度法的光照图恢复算法。
