DDXY Node


Description

This node outputs the sum of both partial derivatives of the specified input value 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.

Notice
For more information on how the derivatives are calculated please follow this link.
