So let's get started.

I'm going to right-click down here in the Node Graph and go to this 3D menu,

and I'm going to pick a piece of geometry that is going to be a sphere,

because earth is a sphere, and I'm going to connect this to our high-res map,

and I'm going to hit one on the keyboard to see it in 3D space.

And you'll see here we can tumble around by holding down Ctrl

and just left-mouse button clicking in here,

and if you click anywhere, we can deselect the selection,

and you'll see right now we have earth mapped to a sphere.

We'll also want to drop a camera down into our 3D space here,

so I'm going to right-click again, and go to 3D,

and I'm going to pick Camera this time,

and you'll see a camera pop up in our 3D space,

and I'm just going to pull that camera back so that we

see our earth within our camera view,

and then I'm going to right-click down here and I'm going to go to the 3D

menu and I'm going to pick a thing called ScanlineRenderer.

ScanlineRenderer is the way that NUKE takes this 3D data

and turns it back into a 2D image.

So, we're going to connect the camera to the cam,

and we're going to connect the sphere to the object/scene,

and now this is going to get really tricky with

these two Viewers that we have up, and NUKE gets a little finicky.

So, follow along with me, and highlight this Viewer,

and pull out this arrow and connect it to the ScanlineRenderer.

You'll notice that both of these Viewers have ones on them right now,

so if I hit one on the keyboard,

I have to make sure that I'm working with the Viewer I want to be

working with to have it manipulate this window up here.

So I'm going to hit two on the keyboard now,

and what we're seeing is what the camera sees in our 3D setup.

So I'm just going to pull out a little by scrolling

with the scroll key on the mouse, I'm going to select the camera,

and I'm going to pull the camera just out a little

more so that we see all of earth.

Now if we select earth in the 3D view, zoom in a little,

select it, we can double-click on this node down here if we want to,

and hold down Ctrl, and we get a rotate manipulator.

So if we rotate this out,

we can get the exact earth we want to see to match

with that other earth that we had up,

and you'll notice that the Viewer only updates once you release the mouse,

and that can get kind of annoying.

So what you can do is you can go down here to the attribute,

you can hold down Ctrl, and hit up or down on the keyboard,

and it'll update as it goes.

So I think in that other image we were taking a look at Africa,

let's get really crazy with it,

and let's set our second Viewer to look at the first image of earth,

and let's go back to that sphere, and with that node selected,

we're just going to try to match up the image as best as we

can to the one that we see on the right.

So it looks like we're just going to be rotating earth a

little in the X and in the Y a little more,

and that looks close enough.
