light mapping中文什么意思
例句與用法
- The basic idea of model - based light map is to explore the captured facial reflection model and recovering light map from a single picture
基于模型的光照圖的基本思想是利用已經(jīng)獲得的人臉反光模型，從單張人臉照片恢復(fù)出人臉所在場景的光照圖。 - 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技術(shù),當繪制較遠處的物體時使用簡化的模型,并采用粗略的紋理采樣技術(shù),繪制近處的物體時使用詳細的模型,并采用線性采樣,這種技術(shù)符合人們觀察物體的習(xí)慣,大大縮小了計算量。 - 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
這個技術(shù)可以應(yīng)用到照片合成中去，對一張帶人臉的照片，恢復(fù)出其光照圖，然后可以利用恢復(fù)的光照圖把新的人臉或其它物體合成到這張照片中去，這樣可以緩和照片合成中的光照不協(xié)調(diào)問題。 - 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實感人臉繪制部分，首先對人臉反光模型進行采樣，并把采樣數(shù)據(jù)組織成反光函數(shù)，然后應(yīng)用工具luxmaster生成不同光照下的各種表情的真實感繪制，其中光照條件用光照圖來表示。 - 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圖技術(shù)的基本思想和框架，然后介紹自行設(shè)計建造的一個半徑為1 . 5米的三維光照架，和一個基于共軛梯度法的光照圖恢復(fù)算法。
