Unity組件：Tilt Shift 移軸特效

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.

移軸特效是景深特效的一種特殊版本，它可以使聚焦區(qū)域和失焦區(qū)域的過渡更加光滑。它更加容易使用并且不容易造成圖像瑕疵。但是，因為它依賴于紋理查找，所以會造成更高的處理開銷。

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.

和其他圖像特效一樣，該特效只能在Unity Pro上進行使用，并且在使用之前必須安裝Pro Standard Assets。

Properties 屬性

• Focal Settings
  聚焦設(shè)置
• Visualize 聚焦平面可視
  Visualizes the focal plane in the game view with a green tint (useful for learning or debugging).
  通過綠色的提示在游戲視圖中顯示聚焦平面（用于研究或調(diào)試）
• Distance 距離
  The distance to the focal plane from the camera position in world space units.
  照相機距離聚焦平面的距離，單位是世界空間單位
• Smoothness 光滑度
  The smoothness when transitioning from out-of-focus to in-focus areas.
  從失焦區(qū)域過渡到聚焦區(qū)域的光滑度
• Background Blur
  背景模糊
• Downsample 降低采樣
  Downsamples most internal buffers (this makes the effect faster but more blurry).
  降低采樣大多數(shù)內(nèi)建緩存（這將使特效操作更加快速，同時也更加模糊）
• Iterations 迭代次數(shù)
  Number of iterations for blurring the background areas (ie, everything behind the focal plane). Each iteration requires processing time.
  模糊背景區(qū)域的迭代次數(shù)（即聚焦平面后的所有東西）。每次迭代都需要一定的處理時間。
• Max Blur spread 最大模糊蔓延
  The maximum blur distance for the defocused areas. Makes out-of-focus areas increasingly blurred.
  失焦區(qū)域的最大模糊距離。可使失焦區(qū)域快速地模糊。.
• Foreground Blur
  前景模糊
• Enable 啟用
  Enables foreground blurring. This typically gives a better result but with a cost in processing time.
  啟用前景模糊。這將給出更好的結(jié)果，但需要消耗一定的處理時間。
• 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數(shù)。每次迭代都需要一定的處理時間。

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.

這個特效需要顯卡擁有像素著色器（3.0）或者OpenGL ES 2.0。臺式機：2004年以后的NVIDIA顯卡（GeForce 6），2005年以后的AMD顯卡（Radeon X1300），2006年以后的Intel卡（GMA X3000）；移動設(shè)備：OpenGL ES 2.0；控制臺： Xbox 360、 PS3。

All image effects automatically disable themselves when they can not run on end-users graphics card.

所有圖像特效如果無法在用戶顯卡上運行時將會自動被關(guān)閉。
