标题: [Unity 组件参考手册]组件：图像特效脚本之图像模糊特效 [打印本页] 作者: . 时间: 2013-1-31 21:37 标题: [Unity 组件参考手册]组件：图像特效脚本之图像模糊特效 The Blur image effect blurs the rendered image in real-time.模糊图像特效实时地模糊所渲染出的图像。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。
Blur effect applied to the scene-----------------------------------------------------------------------------
[Properties 属性] Iterations 迭代次数
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.
模糊操作重复的次数。越多迭代，模糊的效果越好，但同样也消耗更多的时间。
Blur Spread 模糊半径
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.
更大的数值可以让模糊在同样的迭代次数中蔓延的更广，但会带来额外的开销。一般来说选择0.6-0.7范围的数值可以在质量与速度之间达到一个比较好的平衡。 -----------------------------------------------------------------------------[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.这个特效需要显卡拥有像素着色器（2.0）或者OpenGL ES 2.0。台式机：2003年以后的NVIDIA显卡（GeForce FX），2004年以后的AMD显卡（Radeon 9500），2005年以后的Intel卡（GMA 900）；移动设备：OpenGL ES 2.0；控制台： Xbox 360、 PS3。All image effects automatically disable themselves when they can not ***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。
