Hi, in this video, We will discuss vertices edges and faces in blender, so let’s start off with a mesh. A 3d mesh is one of the most frequently used object types in blender so but what makes up a mesh well vertices, edges and faces make up a mesh, so let’s create the most basic mesh possible, so I’m going to go ahead and create a primitive object. Data type, a plane and every primitive object data type by default is a mesh curves, metaballs and lamps and cameras are not meshes, however, curves, metaboles and text can be converted into a 3d mesh, which is commonly done by a lot of 3d artists. So now that we have a plane, I’m now going to go into edit mode by pressing tab so here we can see our vertices edges and faces, so if I just separate this out on its own, so I’m just going to select this vertice by right clicking shift D and just put it anywhere here. A vertex is simply a point in 3d space. Now I can duplicate another vertex by pressing shift D and moving it somewhere here, and then I can shift, right, Click this vertex so that both Vertices are selected and then press F to fill or I can go into the menu here and create an edge, so when two or more vertices form a line, that line is called an edge, so I’m just going to go ahead and create another vertex, so I can. Press ctrl left. Click that will add another vertex and join it to the previously selected one. And then I can shift, right, Click the original vertex and I can press F to create another edge between them and then I can shift, right, Click the third edge and press F again to fill into a face so this time instead of making an edge, I make a face. A face is where three or more edges form a loop and is filled in to create a face generally as a practice in blender, though I prefer to use four vertices to create a face so I can select both of these and remove that edge by pressing X and delete edge. I can then select all four shift, right, Click shift, right, Click shift, right, Click F to create my face and that pretty much forms a plane. So if I just delete everything here by box select X delete vertices, something I’ll have to stream on there. Uh, we can then work with our plane. So over here, you can see the edit mode selections, So right, now we’re on Vertex select so anything I right click will just select the vertices of your currently selected 3d object, all right. Um, this is the edge. Select mode so anything I right. Click on your object will select just the edges only and this is a face select mode so this will just select the faces note that in your 3d model, only the faces will be visible when rendered the edges and the vertices will not be visible. They just simply form a scaffold for you to see how your 3d object is constructed. The faces in blender are what will be visible. When you render your 3d object. The vertices and edges will not be visible when rendered. They just simply form a scaffolding for you to see how your 3d model is structured, basically with our 3d object, we can go ahead and create many different shapes, so for example. If I start with that vertice, I can control. Click control left. Click Ctrl left. Click Ctrl left. Click Ctrl left, click and keep doing that to create interesting shapes, so that is what I pretty much created in two minutes. Just right in front of you. I can then make a face out of this by, uh, shift right clicking and then pressing F every time I select four vertices so every time I set four vertices, I can just simply create the face. There’s no definite rule that you have to create a face using four vertices. It’s just that I do a lot of character modeling work. So it’s been advised to use four vertices to create the faces of a 3d character because, um, it’s a bit complex, but basically it allows your character to deform nicely, So I guess just for the last bit, I don’t really care. Let’s use three vertices. And we just created a nice little. I don’t know a nice little hook or a tag, so so just in the space of one minute. We’ve created a little nice little tag, so that’s a very, very basic. Uh, shoddy 3d modeling of something. So yeah, you can obviously play around with vertices edges and faces as much as you like. You can even select a face. You can shift D to duplicate it. You can go back to Vertex select mode. You can join them up by pressing F. And then you know, joining that into a face as well so you can see how the basic building block of our plane can be used as a foundation to create more complex 3d objects. And that’s how you see. All those little cubes get converted into massively detailed 3d characters and buildings and trees and landscapes and all that stuff it all started from these primitive objects. And, uh, yeah, that’s the basics of the vertices edges and faces in blender, so keep blending. Keep playing around and I hope to see you in the next video.
