So excited for this!
Where did you see this? ;o)
Cheers

Its been a long talked about development for Keyshot8, and confirmed at Renderworld.
Can somebody just summarise what this means please?
Displacement is a process to change the actual geometry by moving polygons and points. This is done by using greyscale maps where white = positive movement and black = no movement.
Imagine you have a sphere with a generated noise map on it. If that map is in any of the current channels of a material you will get reflections, and other things to "fake" bumps on the surface. But if you look at the edge of the sphere where it overlaps with the background you will see that the sphere is still perfectly round and smooth.
With displacement mapping , that same map applied to the displacement channel will actually move the geometry and "displace" polygons from their original position thereby giving the sphere an actual texture that you can then see at the edges of the sphere.
Displacement mapping can be very helpful in adding small ine detail to surfaces that allow for a better representation of reality. Instead of faking reflections off the textured surface of a basketball with a bump map, a similar map may be used to change the actual geometry of the surface of the ball to create that texture in the geometry rather than faking it through bump or normal maps.

Perfect - thanks!
