Every 3D object you build, no matter how complex or how simple, is made up of components. Think of your house. Your house is made of wood, nails, electrical wires, pipes; your car, fiberglass, all kinds of electronics, rubber and alloys 3D models are composed of vertices, edges and polygons. So if I click on Vertices here and by the way the singular is Vertex and I click on the corner, I'll zoom in a little bit, let me go ahead and just grab this guy here. This guy is a single vertex, or a point that connects to this one over here and this one down here and, let me zoom up, this one. So, these four vertices create a polygon, which is this face here and that's what you call the flat side of an object like this. This is a polygon. So I'll go ahead and click on Polygon Mode and now we have a polygon here, here, here and here. So once again, four vertices, or even three vertices, or more, give you a polygon. You also have edges and edges are here, here and so on. Now you might be wondering what's the deal with all this? Why do we need all these different modes to make a model? Well let me go ahead and quickly demonstrate. When you want to just manipulate one point, one vertex, you click on Vertex Mode, click on it and then hit the Y key and you can move it. Notice how I'm changing the shape just on that vertex. I'll go ahead and hit my Spacebar to drop that tool. I'll do the same thing with edges. So I have an edge selected, I'll hit Y on the keyboard and I'm modeling just that edge. So imagine you're making something like a train or a truck or something that needs to have this edge moved, or even a house, say you want to just make a roof or something like that. So I'll click on this guy here and I can move that in and I can slowly but surely make a roof for example, or whatever I want to do. Same thing's true with polygons. I click on the polygon and I can move that whole thing around. So the ability to work with either vertices, edges, or polygons is really going to change based on what you're working on. If I'm working on something like a robot, chances are good I'll probably be dealing with polygons and edges quite a bit. If I'm working on an organic model, like a human being's face where I want to just take my time and refine the lips, or the corners of the eye, then I want to have a lot of control over the details so I'll be working with vertices. So this will change based on what you're doing and there's really no right or wrong as to which mode you're using because every 3D artist works in a different way. And as we get into the projects in the end part of this tutorial I'm going to demonstrate just that. Once we start to make models you might say, well, I like the way he does it, but I prefer to do this instead and both of us would be right. So feel free to experiment. Just click on something and make sure you're in the correct mode and just play around. If you want to, by the way, you can hit the T key on the keyboard which will let you click on anything and it's kind of a fun way to work. So you can just click on the T and then you'll be able to click on anything without having to go up here. And we'll talk more about how to do those tricks later on, but just have a good time and experiment.
