Unity組件：Noise image effect 噪波圖像特效

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

噪波是一種模擬TV和VCR噪波的圖像特效。

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。

Noise effect with high intensity applied to the scene
應(yīng)用于場景的高強(qiáng)度的噪波特效

• Monochrome 單色調(diào)
  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.
  如果開啟該選項(xiàng)，生成的噪波類似于TV噪波。如果關(guān)閉該選項(xiàng)，生成的更像是VCR噪波。它在YUV空間中對顏色值進(jìn)行擾動，所以你可以得到色相變化，主要是洋紅/綠色朝向
• Grain Intensity Min/Max
  噪波強(qiáng)度 最小值/最大值
  The intensity of noise takes random values between Min and Max.
  噪波的強(qiáng)度，在最大值與最小值之間隨機(jī)生成
• Grain Size
  噪波尺寸
  The size of a single grain texture pixel in screen pixels. Increasing this will make noise grains larger.
  噪波生成紋理的大小，增加該值會導(dǎo)致更大的噪波
• Scratch Intensity Min/Max
  劃痕最大/最小值
  The intensity of additional scratch/dust takes random values between Min and Max.
  添加劃痕/灰塵的強(qiáng)度在最小值與最大值之間隨機(jī)取值
• Scratch FPS 每幀劃痕顯示
  Scratches jump to different positions on the screen at this framerate.
  在當(dāng)前幀下顯示劃痕的所在位置情況
• Scratch Jitter 劃痕抖動
  Scratches can jitter slightly while remaining close to their original positions.
  劃痕可以在其原始位置周圍進(jìn)行輕微抖動

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。
