In: Atomic Nodes
A Warp node transforms a base input by warping/pushing pixels as defined by a Gradient (Intensity) input. Unlike the Directional Warp this node pushes away uniformly from white areas, in a direction defined by the slope or gradient of the Gradient Input.The node can be a little tricky to work with, as the result of the effect is very heavily dependant on the Gradient Input: small tweaks to the Gradient can make a huge visual difference with the same Intensity values. Make sure to play around with Contrast, Luminance and scale of the Gradient Input, as well as the Intensity slider on this node.
if you are familar with Normalmaps, you can imagine the workings of this node to be similar to converting the Gradient Input to a Normalmap, and then distorting the Base Input in the direction defined by the Normalmap vectors. In fact, this same thing can be achieved with the Vector Warp. Similar effects can also be found in Slope Blur.
