+# DDXY Node
+
+## Description
+
+Returns the sum of both partial derivatives of input **In**, with respect to the screen-space x-coordinate and screen-space y-coordinate respectively. This node can only be used in the pixel shader stage.
+
+## Ports
+
+| Name        | Direction           | Type  | Description |
+|:------------ |:-------------|:-----|:---|
+| In      | Input | Dynamic Vector | Input value |
+| Out | Output      |    Dynamic Vector | Output partial derivative value |
+
+## Generated Code Example
+
+The following example code represents one possible outcome of this node.
+
+```
+void Unity_DDXY_float4(float4 In, out float4 Out)
+{
+    Out = ddxy(In);
+}
+```
