篩選節點Filter nodes
在著色器設計工具中，篩選節點會將色彩或材質範例等輸入轉換為象徵性的色彩值。In the Shader Designer, filter nodes transform an input—for example, a color or texture sample—into a figurative color value. 這些象徵性的色彩值通常會在進行非相片品質的轉譯時使用，或當成其他視覺效果中的元件使用。These figurative color values are commonly used in non-photorealistic rendering or as components in other visual effects.

| 節點Node | 詳細資料Details | 屬性Properties |
|---|---|---|
| 模糊Blur | 使用高斯函數，使材質中的像素變得模糊。Blurs pixels in a texture by using a Gaussian function. 您可以用此來減少材質中的色彩詳細資料或雜訊。You can use this to reduce color detail or noise in a texture. 輸入：Input: UV: float2UV: float2要測試的材質座標。The coordinates of the texel to test. 輸出：Output: Output: float4Output: float4模糊效果的色彩值。The blurred color value. |
紋理Texture 與模糊期間使用之取樣器產生關聯的材質暫存器。The texture register that's associated with the sampler that's used during blurring. |
| 反滲透Desaturate | 減少指定色彩中的色彩量。Reduces the amount of color in the specified color. 當移除色彩時，色彩值會相當接近灰階。As color is removed, the color value approaches its gray-scale equivalent. 輸入：Input: RGB: float3RGB: float3要去色的色彩。The color to desaturate. Percent: floatPercent: float若要移除的色彩百分比，以 [0, 1] 範圍內的標準化數值表示。The percent of color to remove, expressed as a normalized value in the range [0, 1]. 輸出：Output: Output: float3Output: float3已去色的色彩。The desaturated color. |
明亮度Luminance 提供給紅色、綠色和藍色色彩元件的加權。The weights that are given to the red, green, and blue color components. |
| 邊緣偵測Edge Detection | 使用 Canny 邊緣偵測器偵測到材質中的邊緣。Detects edges in a texture by using a Canny edge detector. 邊緣像素會輸出為白色，而非邊緣像素會輸出為黑色。Edge pixels are output as white; non-edge pixels are output as black. 您可以用這個來識別材質中的邊緣，以便使用其他效果來處理邊緣像素。You can use this to identify edges in a texture so that you can use additional effects to treat edge pixels. 輸入：Input: UV: float2UV: float2要測試的材質座標。The coordinates of the texel to test. 輸出：Output: Output: float4Output: float4如果材質位在邊緣，為白色，否則為黑色。White if the texel is on an edge; otherwise, black. |
紋理Texture 與邊緣偵測期間所用之取樣器產生關聯的材質暫存器。The texture register that's associated with the sampler that's used during edge detection. |
| 銳利化Sharpen | 將材質銳利化。Sharpens a texture. 您可以用此來強調材質中的詳細資料。You can use this to highlight fine details in a texture. 輸入：Input: UV: float2UV: float2要測試的材質座標。The coordinates of the texel to test. 輸出：Output: Output: float4Output: float4模糊效果的色彩值。The blurred color value. |
紋理Texture 與銳利化期間使用之取樣器產生關聯的材質暫存器。The texture register that's associated with the sampler that's used during sharpening. |
