[Unity 组件参考手册]组件：图像特效脚本之移轴特效

.

Tilt Shift is a specialized version of the Depth of Field effect that allows for very smooth transitions between focused and defocused areas. It is is easier to use and is generally less prone to unsightly image artifacts. However, since it relies on dependent texture lookups, it can also have a higher processing overhead.移轴特效是景深特效的一种特殊版本，它可以使聚焦区域和失焦区域的过渡更加光滑。它更加容易使用并且不容易造成图像瑕疵。但是，因为它依赖于纹理查找，所以会造成更高的处理开销。
Tilt shift example. Observe the overall smoothness the effect achieves.
移轴特效例子。注意该特效造成的整体光滑效果。As with the other image effects, this effect is only available in Unity Pro and you must have the Pro Standard Assets installed before it becomes available.和其他图像特效一样，该特效只能在Unity Pro上进行使用，并且在使用之前必须安装Pro Standard Assets。
[Properties 属性]----------------------------------------------------------------------    Focal Settings
    聚焦设置
    Visualize 聚焦平面可视
    Visualizes the focal plane in the game view with a green tint (useful for learning or debugging).
    通过绿色的提示在游戏视图中显示聚焦平面（用于研究或调试）
    Distance 距离
    The distance to the focal plane from the camera position in world space units.
    照相机距离聚焦平面的距离，单位是世界空间单位
    Smoothness 光滑度
    The smoothness when transitioning from out-of-focus to in-focus areas.
    从失焦区域过渡到聚焦区域的光滑度
    Background Blur
    背景模糊
    Downsample 降低采样
    Downsamples most internal buffers (this makes the effect faster but more blurry).
    降低采样大多数内建缓存（这将使特效操作更加快速，同时也更加模糊）
    Iterations 迭代次数
    Number of iterations for blurring the background areas (ie, everything behind the focal plane). Each iteration requires processing time.
    模糊背景区域的迭代次数（即聚焦平面后的所有东西）。每次迭代都需要一定的处理时间。
    Max Blur spread 最大模糊蔓延
    The maximum blur distance for the defocused areas. Makes out-of-focus areas increasingly blurred.
    失焦区域的最大模糊距离。可使失焦区域快速地模糊。.
    Foreground Blur
    前景模糊
    Enable 启用
    Enables foreground blurring. This typically gives a better result but with a cost in processing time.
    启用前景模糊。这将给出更好的结果，但需要消耗一定的处理时间。
    Iterations 迭代
    Number of iterations for blurring the foreground areas (ie, everything in front of the focal area). Each iteration requires processing time.
    前景模糊所使用的迭代次数。每次迭代都需要一定的处理时间。 ----------------------------------------------------------------------[Hardware support 硬件支持]This effect requires a graphics card with pixel shaders (3.0) or OpenGL ES 2.0. Additionally, depth texture support is required. PC: NVIDIA cards since 2004 (GeForce 6), AMD cards since 2005 (Radeon X1300), Intel cards since 2006 (GMA X3000); Mobile: OpenGL ES 2.0 with depth texture support; Consoles: Xbox 360, PS3.这个特效需要显卡拥有像素着色器（3.0）或者OpenGL ES 2.0。台式机：2004年以后的NVIDIA显卡（GeForce 6），2005年以后的AMD显卡（Radeon X1300），2006年以后的Intel卡（GMA X3000）；移动设备：OpenGL ES 2.0；控制台： Xbox 360、 PS3。All image effects automatically disable themselves when they can not&nbsp***n on end-users graphics card.所有图像特效如果无法在用户显卡上运行时将会自动被关闭。
