Eager to know how directional_warp works.

Question

Like the graph shows above, I was expecting the output of the D_warp node to produce same width bricks with relatively same offset distance for each pixel, but as a result while the intensity went higher , those brick widths went more and more narrower.

So what happens to those pixels in the upper part of the bricks?

The areas that are black in the intensity input are not warped at all. The areas that are white are being warped by the maximum that you set. So the white rectangles are warped upwards but only within the constraint of the black areas.

You might find the effect easier to see below :
