Now we're going to look at the components of a polygonal object. I have a polygon sphere here at the center of my scene. With the current transform tools we know, move, rotate, and scale, there's not a lot we can do to change the shape of this other than a little bit of squishing here and there. So when you want to be able to model an object by pushing it around like clay, you need to know how to get at the components of that object. In the case of this polygon sphere, the components are the vertices, which I'll right click on my model and choose Vertex to get at. And now I see, if I go to wire frame mode, it's a little easier to see, these little purple dots that are connected by these light blue lines. If I move that vertex with my Move tool, you can see I'm reshaping the object so that at its base level, the point, or vertex, is the lowest level that we have to deal with on a polygon object. As I'm moving these points around, what I'm affecting are the edges; that's the blue lines we see here that connect the different points together, and in turn, the faces that are created by a boundary, in this case, a four, or in some cases, three edges. When I right click on the model, I can choose from vertex, edge; so now I'll select one edge and move that around and that has the same effect as moving the two vertices that are at the end points of that line. When I have an edge selected, I can also rotate it or scale it, and this holds true for having multiple points. So if I right click and choose Vertex and grab a collection of vertices such as the tops of this object, I have to be careful about not accidentally selected vertices that I don't want. Now I can scale all of those, translate, and rotate. The third component that I talked about is the Face. So by right clicking on the model and choosing a South position on the Marking menu, I'll now be able to select individual faces in order to translate them, rotate them, or scale. And this of course, also works with a collection of faces, so if I drag a selection around all of the faces that make up this ring and then start scaling out, I can sort of uniformly increase the size of this bottom. Another illustration of the components of a polygon can be seen if I choose from the Mesh menu, this is in the polygon menu set, and I choose Mesh, and from here there's a Create Polygon tool. And the instruction here is: Click to place each vertex. To finish, press Enter. So each time I click, I'm setting down one vertex. I've set down two vertices, and now I see an edge, and as soon as I click the third vertex, I see where the face will be created if I press Enter. So I go ahead and press Enter on the keyboard and now I have a new polygon object. Let's look at this from the perspective view, that is a triangle. This still has if I right click and choose Vertex, repositioning with the vertices, right click and choose Edge, reposition with edges, and in this case, right click and choose Face. There's only one face so that looks the same as moving the entire transform node with the Move tool. If I want to get out of this component level editing, I can right click and choose Object mode from the northeast section of the Markng menu.
