3D result of original
Exfoliation is the process of erosion of land by repeated cycles of heat and cold. These cycles cause material at higher levels to become detached, and the resulting material to move downslope. The resulting landscape is smoother, and appears older. Compare the Appalachian mountains to the Rocky mountains; the Appalachians are much smoother and less tall. This is because they are older, and exfoliation has been working on them for a very long time.
This operator applies a digital analog of this process to heightfields.
Exfoliation Operation Dialog
16.83.1 - Exfoliation Controls
220.127.116.11 - Trends
Operator dialog controls that have a Trend button next to them offer animation functionality. Trend allows you to set that variable over a set of frames. Each frame of the animation can be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. Variables that have multiple states can be set to any of a number of values in the trend. Variables that are either on or off can only have an on or off value in the trend. You will notice that the trend graphs have equidistantly spaced vertical lines. Each of these lines represents a frame in the animation. The number of frames can be altered using Sequence controls... in the TimeLine pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames.

18.104.22.168 - Stress
This control increases the intensity of the heat/cold cycles. A higher value causes more erosion.
22.214.171.124 - Cycles
This controls the number of erosion cycles. More cycles will cause more erosion.
