Wishlist: Extract Slope Component

So, something I think would be useful is an 'Extract Slope' green component. This would take an input heightmap, and return the vector / slope direction. This is essentially the same function as creates a normal map. FF can already do normal maps (and very quickly at that) so this shouldn't be very hard to include.

The resulting component can be used in all sorts of useful ways:
-Creating elements on one side of a shape, and not another. Such as windows on a hull, or trees on a particular side of a hill.
-Isolate individual faces of a shape: ie outline each triangle of a pyramid.
-Create directional wear, such as lichen on the top of a rock, or rust on top of a machine.
-Make more interesting shapes using existing FF components.

I realize you can do this by rendering out a normal map, and splitting out the RGB components, but it would open more possibilities to have it as part of a filter.

I've actually created such filters (for example, exact normal map ) by using some beta 3 components. But the beta stage is not completed yet =(

Y E S !

We are all ready!
