Unity組件：Blur image effect 圖像模糊特效

The Blur image effect blurs the rendered image in real-time.

模糊圖像特效實(shí)時(shí)地模糊所渲染出的圖像。

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(jìn)行使用，并且在使用之前必須安裝Pro Standard Assets。

Properties 屬性

• Iterations 迭代次數(shù)
  The number of times the basic blur operation will be repeated. More iterations typically give a better result but each has a cost in processing time.
  模糊操作重復(fù)的次數(shù)。越多迭代，模糊的效果越好，但同樣也消耗更多的時(shí)間。
• Blur Spread 模糊半徑
  Higher values will spread out the blur more at the same iteration count but at some cost in quality. Usually values from 0.6 to 0.7 are a good compromise between quality and speed.
  更大的數(shù)值可以讓模糊在同樣的迭代次數(shù)中蔓延的更廣，但會帶來額外的開銷。一般來說選擇0.6-0.7范圍的數(shù)值可以在質(zhì)量與速度之間達(dá)到一個(gè)比較好的平衡。

Hardware support 硬件支持

This effect requires a graphics card with pixel shaders (2.0) or OpenGL ES 2.0. PC: NVIDIA cards since 2003 (GeForce FX), AMD cards since 2004 (Radeon 9500), Intel cards since 2005 (GMA 900); Mobile: OpenGL ES 2.0; Consoles: Xbox 360, PS3.

這個(gè)特效需要顯卡擁有像素著色器（2.0）或者OpenGL ES 2.0。臺式機(jī)：2003年以后的NVIDIA顯卡（GeForce FX），2004年以后的AMD顯卡（Radeon 9500），2005年以后的Intel卡（GMA 900）；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(yùn)行時(shí)將會自動被關(guān)閉。
