dF/dU node

Access: Nodes > Math > dF/dU

Outputs the rate of change of the input with respect to the U texture coordinate.

Note: This node will not work for displacement (it is fragment shader only).

Input (RGB)	Output (RGB)
Uniformly mapped UVs with constant Input color	0.0, 0.0, 0.0
Horizontal ramp over 1 unit of U	1.0, 1.0, 1.0 per unit U
UV scale doubled (stretched UVs) with standard input ramp	0.5, 0.5, 0.5

dF/dU node inputs

UV	Texture coordinate map.
Input	The signal to differentiate relative to U.

Output

The partial derivative of the input signal along the U texture axis.
