Mist
雾
Mist can greatly enhance the illusion of depth in your rendering. To create mist, Blender basically mixes the background color with the object color and enhances the strength of the former, the further the object is away from the camera. The Mist settings are in the Mist Stars Physics Panel and are shown in Mist buttons. 雾(Mist)可以在渲染中提高立体感效应。通过创建雾，Blender主要是根据物体颜色和模型的强度来混合背景色，更远处的物体则会脱离摄像机。雾(Mist)的设置是在雾与星的物理学(Mist Stars Physics)面板。
The Mist雾 Button toggles mist on and off. The row of three Toggle Buttons below this button set the decay rate of the mist as Quadratic, Linear, and Square Root. These settings control the law which governs the strength of the mist as you move further away from the camera.
雾(Mist)按钮用来切换雾的开和关。下面的三个按钮用来设置雾的衰减率：二次方程(Quadratic)，线性(Linear)，和平方根(Square Root)。当您远离摄像机时，这些设置用来控制决定雾的强度的规则。
The mist begins at a distance from the camera as defined by the Sta: button, and is computed over a distance defined by the Di: button. Objects further from the camera than Sta+Di are completely hidden by the mist.
雾从一个由Sta:键定义的距离开始，由Di:键的定义计算距离。与摄像机的距离比Sta+Di相加的值更大的物体会完全隐藏在雾中。
By default, the mist covers all of the image uniformly. To produce a more realistic effect you might want to have the mist decrease with height (altitude, or z) using the Hi: NumButton. If the value of this button is non-zero it sets, in Blender units, an interval, around z=0 in which the mist goes from maximum intensity (below) to zero (above).
默认的，雾均匀的覆盖所有的图像。为了产生更真实的效果，你也许会想让雾随着高度(decrease)(海拔(altitude)或z轴)减少。在 Hi: 处设定一个值。当这个值非零时，以blender的单位，一个间距，围绕 z=0 雾在最大强度(向上)到零(向下)之间变化。
Finally, the Misi: NumButton defines the intensity, or strength, of the mist. Mist test setup shows a possible test set up.
最后， Misi: 滑钮定义了雾的强度，或者说浓度。Mist test setup演示了一种可能的测试设置。
Rendering without mist (left) and with mist (right). shows the results with and without mist. The settings are shown in World set up.; the texture is a plain procedural cloud texture with Hard noise set. Rendering without mist (left) and with mist (right).显示了使用或不使用雾的结果。设置见World set up.。纹理使用的是是加了硬噪波的程序贴图云。

To see what the mist will actually affect, select your camera, go to Editing Context (F9) and press the Show Mist TogButton in the Camera Panel. 为了看到雾的实际影响，选择您的摄像机，到编辑(Editing)相关(F9)并按下摄像机(Camera)面板上的显示雾(Mist)按钮。 The camera will show mist limits as a segment projecting from the camera starting from Sta and of distance Di. 摄像机将会用一个突出的截面显示雾的界限。 |
