Join Deke McClelland for an in-depth discussion in this video Creating a basic 3D shape, part of Photoshop CS5 Extended One-on-One: 3D Fundamentals.
Here's the final Saturn image. It's ultimately a digital painting created inside of Photoshop CS5 Extended. WHich is to say it's not a photograph, in other words, captured by a Voyager spacecraft or something along those lines. Even though it is pretty darn scientifically accurate. It's based on some data I was able to find in the NASA and JPL sites. A few others as well. And the wonderful thing is it's actually pretty darn easy to throw together, because ultimately we've got a sphere surrounded by these rings. The rings have varying levels of opacity.
But we'll solve that problem pretty quickly as you'll see. The toughest thing is just working in 3D space inside of Photoshop because it's a very different space than you Photoshop users have been working in before. We have to make sure that these various 3D objects are fitting together properly. Specifically the sphere needs to be inside the rings, not several million miles away. Anyway, let's get started by creating that basic sphere shape. So I am going to switch to this image here. It's called Space painting.psd and it comes to us from T. Jefferson of the Fotolia Image Library.
You'll notice that there are two layers here. One is called universe and the other is called ring. So I'll go ahead and turn it on. And it's very simple shape layer that is created using the 2D shape tools inside of Photoshop. Specifically, the tool I used was the Ellipse tool here. So I drew a big circle and then I drew a smaller circle inside of it, and set it to the Subtract mode so the smaller circle ended up cutting a hole in the larger one. Now if I was to go up-- which I could. I could go up right now to the 3D menu and choose New Shape From Layer. Before I do this I should caution you. If you don't see a 3D menu, then you're working in a standard version of Photoshop.
You have to have Photoshop CS5 Extended in order to follow along with this entire course. Now if I was to go up here to New Shape From Layer, which is how you access the basic 3D objects that are included with Photoshop, and I were to choose Sphere, which is the shape that I am looking for, I would wrap this universe layer around that sphere. That's not what I want to do. So I'll press Ctrl+Z, or Command+Z on the Mac. Instead what I want to do is create a new layer. I am going to do that by pressing Ctrl+ Shift+N or Command+Shift+N on the Mac. I'll call this new layer planet and I'll click OK.
Now I revisit that command again. I'll go up to the 3D menu, choose New Shape From Layer, and then choose Sphere. That ends up creating this basic spherical shape right here. It's currently behind the rings. That's why it looks like it's kind of trapped inside the rings. Just to make it easier to work with for the moment anyway, I am going to make it smaller. I am going to do that by dropping down to this 3D tool here. By default it's the Object Rotate tool, but it really doesn't matter which of these five tools are selected. All of them affect the entire scene and that's what we're looking for. And we're not actually getting use the tool, because I want you to get it in the habit.
It's just hard to figure out these tools when you're working on a 2D screen, which allows you to drag up and down and side to side. But how do you drag in and out of 3D space? Well, obviously you can't. So Photoshop has to figure out the difference and as a result the tools don't always behave the way that you think they would. So it's easier to start in my opinion by editing the objects using this 3D widget right here that includes these red, green, and blue arrows, as you can see. Now if you don't see the 3D widget on screen, which Photoshop calls the 3D Axis, then go to the View menu, choose Show, and choose 3D Axis right there.
And that should bring it up on screen. All right, so mine is already available. Notice right here at the intersection of these various axes we have this cube. And if you hover over the cube it's going to turn yellow. You might see some other things pop up on screen there. But once it turns yellow you're good to go. If you look very closely at the video you can see that the cursor changes to these three arrowheads pointing in opposite directions. And what it's telling you is you're going to scale the object proportionally. So if you drag up you're going to make the object larger. If you drag down you're going to make it smaller.
Obviously, we want it smaller in this case so I'll drag down and we end up with this effect here. So we now have a 3D sphere set inside some 2D rings. In the next exercise I'll show you have to wrap a texture around that sphere.
