Blender is a powerful open-source tool for 2D and 3D graphics, full-on animation, compositing, and post-production. It is used to create movies and special effects, even in HD. In Blender Essential Training, Roger Wickes offers new Blender users a thorough explanation of its interface, tools, and features. He also demonstrates practical techniques and shows how to access the online and openndash;content resources of this amazing tool. Specific 3D techniques covered include navigating in 3D space, using cameras and lights, and rendering. Roger demonstrates how to rig, animate, and composite a character over live action. Exercise files accompany the course.
So when we talk about editing a mesh, I thought it would be helpful to look at something that's already been done and this is the rabbit from Big Buck Bunny. So, let's just look at a mesh and see what it's composed of and see what kind of components there are to a mesh object. So, we've talked about the different modes, how you can select the mode here from the Header menu or you can just press Tab on your keyboard and that tabs you right into Edit Mode. And here you see all of the vertices, now there is a lot more than the 8 vertices that there were in the cube. But this object started out as a simple cube and all of the different mesh editing tools were used to create this shape.
Right now, we are looking at the vertices. These little blue dots are the vertices that make up and define the shape of the mesh. That's indicated down here in your Header bar under Vertex select mode. We can look at the edges, which is the lines that are connecting these vertices together, and right-click and select now just the edges that define the mesh. And you can see that sometimes I'm selecting the edges that are on the front side and sometime I'm selecting edges that are on the back side, namely on this little bunny tail there.
If that's kind of distracting, you can hide that by occluding, which means to make it invisible, any background geometry and now I'm looking at just the front. Also, I want to note too that we can turn Off this grid that's in the background, a lot of people find that a little confusing, by going to our View Properties and turning Off Grid Floor. Now it looks not as distracting. We can of course use all of the standard window Pan & Zoom controls to zoom in on any pushing of the mesh by using the middle mouse wheel and/or clicking the middle mouse wheel and holding down the Shift key to pan and zoom and translate the view.
So that we can see this mesh that we are working on. The last component of a mesh is the Faces. Now, if we look at the Faces, these are the surfaces that are connected by the edges and the edges are defined by the vertices. So that's how vertices, edges, and faces go together to create this mesh shape that we see.
