This course provides an overview of modeling, animating, and rendering 3D graphics in the open-source software Blender 2.6. Beginning with a tour of the Blender interface, author George Maestri shows how to create and edit basic objects, work with modifiers and subdivision surfaces, and apply materials and textures. The course also demonstrates lighting 3D scenes, setting up and using cameras, animating objects, and assembling basic character rigs.
When you start modeling in Blender, probably the best way to do it is to just start with a primitive and then reshape it, add detail and turn it into the model that you want. Now, you don't have to start with a primitive, but a lot of times it's the best way to start. Now in order to edit any object, including primitives, we need to go into Edit mode in Blender. So, right now we're in what's called Object mode, where we can select the actual objects in the scene. So I'm going to right-click on the sphere and then I'm going to go into Edit mode.
So we can get to it here, we have Object Mode, and then we have a number of other modes, but the one we want to go to right now is called Edit Mode. And notice, when I do this, the actual look of the object changes. We get this wireframe on shaded look, and this exposes the underlying structure of my object, and so now I can start reshaping it. Now in order to do this, I need to select vertices, edges or faces.
So let me show you the difference between each of these. Now, we have some buttons here along the bottom, and they basically switch us between the different modes. So, I'm going to go ahead and click on the leftmost one, and this is the Vertex button. So when I right click to select any one of these, I can select the vertices, which are basically the points. If I go over here to Edges, I can right-click on any one of these to select the edges, which are basically lines.
If I go here, then I can select faces, which are basically plains that define the surface of the object. Now, another way to get to these and this is probably going to be a little bit faster, is to hold down the Ctrl key and touch the Tab button. When you do that, we have a little menu that pops up and allows us to switch between Vertex, Edge and Face. So, any one of these can be used to reshape an object.
So, if I'm in Vertex mode here, I can move that vertex however I want. If I'm in Edge mode, and again, right-clicking on the edge, I can move the edge. Hit Ctrl tab again and select Face, then I can select that Face and move that as well. Now, before we actually get into actual editing of moving objects around, let's take a look at some more selection options that we have. I'm going to go ahead and hit Ctrl+Tab and go into Vertex mode and then I'm going to hit A to deselect everything.
In fact, the A key in Edit Mode works very much the same as the A key in Object Mode except it only works on that particular mesh that you have active. So, if I hit A that selects everything in my mesh, but it doesn't select everything in the scene, only that stuff in the mesh. Hit A again, and it deselects. So I'm going to go ahead and deselect everything and let's take a look at some more selection tools. Well, obviously we know about A, but remember in Blender we also have B and C.
So if I select B it brings up my crosshairs just like it does in Object Mode, and I can left-click and select some additional vertices. If I hit B again, I can select some more, and again, A, deselects. Now, C is again my Circle Tool, so if I want I can hit my plus or minus keys on my num pad or just roll my mouse wheel to make this bigger or smaller, and then I can select however, many of these that I want.
In fact, if I want, I can click and drag and actually just paint my selection, which is kind of nice, and right-click ends that mode. And again, I'm going to hit A to get rid of that. Now, another really handy tool, which you don't have in Object Mode is the lasso select, and you can do this with your left-click and your Ctrl button. So, I hit Ctrl+Left-Click and I can lasso select whatever I want. So that can be very handy, particularly if you're trying to select in very tight areas.
This could be a very good way to select very specific types of vertices. So those are some ways of selecting Edges, Faces and Vertices in Blender. So, go ahead and practice with these tools, and then let's go ahead and get into actually modeling, in the next lesson.
