Unity3D图像后处理特效——Noise image effect

Noise is an image postprocessing effect that can simulate both TV and VCR noise.

添加噪声是一种模拟TV和VCR噪声的图像特效。

 

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。

 

Noise effect with high intensity applied to the scene

应用于场景的高强度的噪声特效

Monochrome   单色调	If enabled, Noise is similar to TV noise. If disabled, it more closely resembles VCR noise - it distorts color values in YUV space, so you also get hue changes, mostly towards magenta/green gues. 如果开启该选项，生成的噪声类似于TV噪声。如果关闭该选项，生成的更像是VCR噪声。它在YUV空间中对颜色值进行扰动，所以你可以得到色相变化，主要是洋红/绿色朝向
Grain Intensity Min/Max 噪声强度 最小值/最大值	The intensity of noise takes random values between Min and Max.   噪声的强度，在最大值与最小值之间随机生成
Grain Size 噪声尺寸	The size of a single grain texture pixel in screen pixels. Increasing this will make noise grains larger. 噪声生成纹理的大小，增加该值会导致更大的噪声
Scratch Intensity Min/Max 抓痕最大最小值	The intensity of additional scratch/dust takes random values between Min and Max. 新增的抓痕/尘埃条的强度在最小值与最大值直接随机取值
Scratch FPS 每帧抓痕显示	Scratches jump to different positions on the screen at this framerate. 在当前帧下显示抓痕的所在位置情况
Scratch Jitter 抓痕抖动	Scratches can jitter slightly while remaining close to their original positions. 抓痕可以在其原始位置周围进行轻微抖动

 

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 run 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。
