Displacement node: Basic workflow

“

- [Narrator] The displaced geoNode will displace a polygonal surface but you must first create a lot of polygons which makes it a heavy render. A displacement shader works differently by creating needed polygons on the fly only as they enter the render window. In previous versions of Nuke, the displacement shader was embedded in the ScanLineRender node but in Nuke 7 it's been moved to a separate node, the displacement node. So the images we're using are in the exercise files, you can play along too, put this back where it belongs. Now let's take a look at our 3D set up. We have a card and a camera, so go to our 3D view. So here's our card, and our camera and you'll notice the card only has 4 polygons along here and 4 there for a total of 16 polygons for the whole card, in other words a very low polygon count. Now let's add our 3D shader, we'll select our texture map image, go to 3D, shader, displacement, and nothing happens. The reason is we haven't hooked up any displacement yet to…
