What does that mean? A few images might make it more clear. Let’s say we have a basic perlin noise terrain:<\/p>\n And we have another terrain as a model. (Edit: I’ve updated this example to be more obvious!)<\/strong><\/p>\n Quite different from basic Perlin Noise! Nonetheless, the mimic device transforms the input terrain shown in the first image using the above as a reference… into this:<\/p>\n You can see that it follows the same general shape as the original input, but it matches the elevation range, and more importantly, matches the elevation profile of the model input! Note that the Mimic device cannot<\/em>\u00a0introduce detail that wasn’t there to start with –But it does make what is there look the same.<\/p>\n Here’s another example. Let’s say our model terrain was terraced (in this case, by adding a Terrace device to a Voronoi:<\/p>\n The terraced voronoi looks like this:<\/span><\/p>\n <\/p>\n While the input terrain looks like this:<\/p>\n And sure enough, the terraces are replicated on the mimic!<\/p>\n Hopefully you can start to see how how powerful this ability could be…<\/p>\n The immediate use cases that I developed the device for include:<\/p>\n An interesting side effect of the Mimic is that it can actually be used to “erase” changes made to a source terrain, as long as those changes don’t reverse the profile curve of the terrain. For example: In the above example world, if we moved the terrace device from the Voronoi chain to the Perlin Noise chain, \u00a0we could take that resulting terraced perlin noise input and actually remove the terraces from it by using the smooth-sided terrain as a mimic reference!<\/p>\n This surprising power works because the Terrace device doesn’t create completely flat ledges, and so can be reversed. If that was not the case (for example, if you were trying to reverse the terraces from an 8bit input file) then the Mimic would not be effective as-is — you would have to blur the input terrain first.<\/p>\n Of course, nothing is perfect. What can’t the Mimic do?<\/span><\/p>\n Balanced against those relatively few caveats, however, is a lot of utility.<\/p>\n Excited?<\/p>\n I am.<\/p>\n","protected":false},"excerpt":{"rendered":" Time for a sneak peek at another new WM 2.9 device: The Mimic Device.
