As always, sorry for my bad english
So, there is a filter that is very commom in image editor programs, called “edge detection”. Basically (at least, that’s what I think it does…) it looks for abruptly changes of colors in the image, so it’s kind of looking for “borders” between colors, and then create lines among these borders. Take a look at this picture:
Now, take a look at this:
This is a plane made of voronoi cells deformed by a noise texture (a different kind of deformation, which you can find here:
I simply want to get the borders from these materials, the border between the cells. If there is a way to make the material detect the boundaries between the cells (it can judge by the colors, just like the filter), it would be very useful. It’s basically that, so, if you can help me, I’ll be very happy!
