This are the settings of the raytrace panel ( on the right side of the material editor you can see written raytrace instead of standard ) 这是光线追踪贴图的设置面板（右侧是贴图浏览器，你可以看到标为“ raytrace ”的材质在标准材质的上面） 。
In a ray tracing scene , we first position the objects and define the shape and surface properties e . g . colour , reflectivity and texture for each object 在进行光线追踪前，我们必须先设定物件的位置形状以及表面特性例如颜色反光度和材质。
The rules used for this light - object interaction are somewhat simplified from those of nature but are still accurate enough to produce photo - realistic results 虽然光线追踪应用了较自然界真实状况简单的数学模型，但仍足以产生几可乱真的图像。

A light tracing tree ( ltt ) can be set up according to the light tracing theory and the covering area can be simulated using the information saved in the nodes of the ltt 该算法根据光线追踪理论和有关光学原理建立光线传播树，并通过可视化方法在计算机上对光线照射到的区域进行仿真。
We then specify where the observer s eye will be located . the ray tracing program will mathematically model the objects , the light rays and the observer and compute the colour for each pixel on the screen 光线追踪的程式会利用数学模型模拟物件光线及观察者之间的关系，从而计算观察者在电脑屏幕上应看到的影像。
The attenuated dmap shadow network demonstrates that a relatively simple network can save a tremendous amount of render time , in many situations , by eliminating the need for raytraced shadows 削弱的深度贴图阴影网络证明了一个相对简单的材质网络能节省极大量的渲染时间，在多个位置，通过它消除必需的光线追踪阴影。
Light sources are then set up at assigned locations . we then specify where the observer s eye will be located . the ray tracing program will mathematically model the objects , the light rays and the observer and compute the colour for each pixel on the screen 光线追踪的程式会利用数学模型模拟物件、光线及观察者之间的关系，从而计算观察者在电脑屏幕上应看到的影像。
Clre also used a special strategy to tracing the ray that decreases the variant of monte carlo technology . at the prophase , clre introduced some ideas based on signal processing to benefit the raytracing fragment ’ s quality and performance Clre使用基于montecarlo积分技术的并行式光线追踪作为其核心渲染算法,通过结合光线追踪算法和辐射度算法的优点,达到了较高的渲染质量。
In order to simulate ray trace reflection effect , the mirror reflection and curving reflection have been distinguished , giving an predigest method simulating approximate the ray trace effect by use of mirror geometry and the middle curving surface texture mapping 为了提高实时渲染图像的质量，模拟光线追踪反射效果，本文将反射分成镜面反射和曲面反射两种类型进行了讨论，利用镜面几何和中间曲面贴图映射方法给出了近似模拟光线追踪反射的简化技术。
