黑体

The Blackbody Node can be used to assign temperatures of real colors. In this example, the result of an Ambient Occlusion calculation is used to vary the Blackbody temperature. In the proximity of objects, the warmer colors will be output than in open areas that lie farther away from objects. 黑体节点可以用来分配真实颜色的温度。在此示例中，使用环境遮挡计算的结果来改变黑体温度。在物体的附近，较温暖的颜色会比远离物体的开放区域输出

In physics, a black body is an idealized object that absorbs all incident electromagnetic radiation. In our case, a color change will also be defined for certain temperatures, comparable to a piece of metal to which heat is applied. This produces colors that run from red to yellow, white and bright blue.

在物理学中，黑体是一个理想化的物体，它可以吸收所有入射的电磁辐射。在我们的例子中，颜色的变化也被定义为一定的温度，相当于一块金属加热。这就产生了从红色到黄色，白色和明亮的蓝色的颜色。
