WEBVTT 1 00:00:00.000 --> 00:00:04.000 Welcome to Subdividing an Edge and 2 00:00:04.000 --> 00:00:08.000 to Sphere! So in this video we will be using this 3 00:00:08.000 --> 00:00:12.000 Subdivision Tool to add edge geometry, so adding some more 4 00:00:12.000 --> 00:00:16.000 vertices on an edge to take more control out of it, and 5 00:00:16.000 --> 00:00:20.000 using To Sphere to create a circular 6 00:00:20.000 --> 00:00:24.000 hole. So let's hop straight into Blender and carry 7 00:00:24.000 --> 00:00:25.500 these out! 8 00:00:25.500 --> 00:00:29.500 So here we are in Blender with our to soon 9 00:00:29.500 --> 00:00:33.500 be bowling ball! So first of all, a bowling ball 10 00:00:33.500 --> 00:00:37.500 is nice and smooth, so I'm going to 11 00:00:37.500 --> 00:00:41.500 find on our Tool Shelf here, under the Tools Tab, 12 00:00:41.500 --> 00:00:45.500 Smooth Shading, so we've got a nice smooth surface, 13 00:00:45.500 --> 00:00:49.500 and I'm going to hop over into Edit Mode. 14 00:00:49.500 --> 00:00:53.500 Now we've got a series of triangles we can work at here, and the 15 00:00:53.500 --> 00:00:57.500 subdivision, on the modifier, that we chose 16 00:00:57.500 --> 00:01:01.500 has generated a few artifacts. If you look 17 00:01:01.500 --> 00:01:05.500 closely, there are a series of six triangles or 18 00:01:05.500 --> 00:01:09.500 hexagons being created, but also, occasionally there's a pentagon 19 00:01:09.500 --> 00:01:13.500 where they join up and around that pentagon the geometry's just a bit 20 00:01:13.500 --> 00:01:17.500 distorted, around there. So we're going to stay clear 21 00:01:17.500 --> 00:01:21.500 of the ones with five going around, 22 00:01:21.500 --> 00:01:25.500 and we're going to stick to the six ones. So I'm going to find a space in the middle 23 00:01:25.500 --> 00:01:29.500 and we're going to create one of our holes. So here is 24 00:01:29.500 --> 00:01:33.500 absolutely fine! So I'll go to Face Select 25 00:01:33.500 --> 00:01:37.500 and click on these faces here, I'm just going to select a group of 26 00:01:37.500 --> 00:01:41.500 them. You could use a series of selection methods to do that, 27 00:01:41.500 --> 00:01:45.500 I'm just holding down Shift. And what we can do 28 00:01:45.500 --> 00:01:49.500 here is literally extrude in. So we'll see what that looks 29 00:01:49.500 --> 00:01:53.500 like, if we do that. So we've got that there, that's being extruded 30 00:01:53.500 --> 00:01:57.500 in. That's great! Let's see what that looks like by hopping straight 31 00:01:57.500 --> 00:02:01.500 back over into Edit Mode! So it looks like there's a hole 32 00:02:01.500 --> 00:02:05.500 in the ball, which is great! It's quite a deep hole, I haven't gone through the other 33 00:02:05.500 --> 00:02:09.500 side, fortunately, no control over that! And 34 00:02:09.500 --> 00:02:13.500 it looks very rough, I mean that looks absolutely horrible. It doesn't 35 00:02:13.500 --> 00:02:17.500 look like an appropriate size hole, to begin with, and neither does it look the 36 00:02:17.500 --> 00:02:21.500 right shape, it's a hexagonal hole. so even though we've got Smooth Shading 37 00:02:21.500 --> 00:02:25.500 turned on, that's not hidden the fact that we've cut a hexagon 38 00:02:25.500 --> 00:02:29.500 into the surface of our model. So let's hop back on over 39 00:02:29.500 --> 00:02:33.500 into Edit Mode, and I'm going to undo that last step 40 00:02:33.500 --> 00:02:37.500 of geometry. So we need to have more 41 00:02:37.500 --> 00:02:41.500 of a step going in, and one of the easiest ways to do this is to, 42 00:02:41.500 --> 00:02:45.500 first of all, we're going to select an edge loop. So we want to 43 00:02:45.500 --> 00:02:49.500 select the edge loop that's going around our model here, 44 00:02:49.500 --> 00:02:53.500 the hexagon basically, and 45 00:02:53.500 --> 00:02:57.500 if we go to Edge Mode, hold down Alt, and try and do that, it won't work. 46 00:02:57.500 --> 00:03:01.500 And the reason it won't do that is because there isn't an edge loop that's well defined there. 47 00:03:01.500 --> 00:03:05.500 It doesn't know which way to go. I mean these are all triangles, 48 00:03:05.500 --> 00:03:09.500 so it doesn't know which way to go. Each time, it doesn't know whether to go this way, 49 00:03:09.500 --> 00:03:13.500 that way, this way, or any other way. In fact, it's got one, two, three, 50 00:03:13.500 --> 00:03:17.500 four, five possibilities and directions, so Blender just does 51 00:03:17.500 --> 00:03:21.500 not know which way to go. However, we can help it 52 00:03:21.500 --> 00:03:25.500 by simply selecting some triangles again 53 00:03:25.500 --> 00:03:29.500 and insetting. So I'm going to use the shortcut key I, 54 00:03:29.500 --> 00:03:33.500 and it doesn't have to be by much, it can just be by that. Now the 55 00:03:33.500 --> 00:03:37.500 moment we've done that, we've actually broken up and we've created a series of 56 00:03:37.500 --> 00:03:41.500 quads around the outside of our new hexagon. 57 00:03:41.500 --> 00:03:45.500 Now when we do that and we select an edge loop, 58 00:03:45.500 --> 00:03:49.500 when we hold down Alt, we actually get the edge loop itself, which is 59 00:03:49.500 --> 00:03:53.500 brilliant! That's exactly what we wanted! Now the 60 00:03:53.500 --> 00:03:57.500 tool, To Sphere, can be gotten at in two ways. You can 61 00:03:57.500 --> 00:04:01.500 hold down Shift, Alt, and S, 62 00:04:01.500 --> 00:04:05.500 and we see in the lower-left the command, To Sphere, 63 00:04:05.500 --> 00:04:09.500 has appeared, and that is one of these 64 00:04:09.500 --> 00:04:13.500 proportional things, so it goes from 0 to 1. 65 00:04:13.500 --> 00:04:17.500 And, as we can see, it's going backwards and forwards, it's making 66 00:04:17.500 --> 00:04:21.500 absolutely no difference to our hexagon, and the reason 67 00:04:21.500 --> 00:04:25.500 for that is, because there's only six edges that is 68 00:04:25.500 --> 00:04:29.500 already spherized as much as it can. So we need to 69 00:04:29.500 --> 00:04:33.500 add more edges, even though the shape will be the same, but we need to 70 00:04:33.500 --> 00:04:37.500 add more edges, so that it can spherize 71 00:04:37.500 --> 00:04:41.500 or make it circular, in this case, since we're dealing with 72 00:04:41.500 --> 00:04:45.500 almost a 2D object. So 73 00:04:45.500 --> 00:04:49.500 I'm going to cancel that by hitting Escape. The other way you can get to To Sphere 74 00:04:49.500 --> 00:04:53.500 is to hit the Spacebar. And ooh, you can see that was my 75 00:04:53.500 --> 00:04:57.500 last search! So this is a very good lookup 76 00:04:57.500 --> 00:05:01.500 for commands, if you can't find them. 77 00:05:01.500 --> 00:05:05.500 And we can see, if I type in "sphere", it gives us a couple of 78 00:05:05.500 --> 00:05:09.500 choices there and To Sphere, 79 00:05:09.500 --> 00:05:13.500 and it also gives the shortcut keys Shift, Alt, 80 00:05:13.500 --> 00:05:17.500 and S. So brilliant! But we know that's not working, at the moment, so we 81 00:05:17.500 --> 00:05:21.500 have to subdivide this edge. So we leave that 82 00:05:21.500 --> 00:05:25.500 selected and we can do two options, we can either go to 83 00:05:25.500 --> 00:05:29.500 Subdivide, here on the Tool Shelf, or we can go to Mesh, 84 00:05:29.500 --> 00:05:33.500 Edges, and Subdivide, or you can get to another 85 00:05:33.500 --> 00:05:37.500 menu, which is on the W key, as well. And 86 00:05:37.500 --> 00:05:41.500 if we go W, and Subdivide is right at the very 87 00:05:41.500 --> 00:05:45.500 top, very powerful, and take note of what 88 00:05:45.500 --> 00:05:49.500 else is on here, it's a Specials menu. So we just want 89 00:05:49.500 --> 00:05:53.500 Subdivide, and that's cut every one of these edges 90 00:05:53.500 --> 00:05:57.500 into two, because we've subdivided by 1. 91 00:05:57.500 --> 00:06:01.500 So it's cut everything into two. We subdivide by two, 92 00:06:01.500 --> 00:06:05.500 it's cut everything in to 3 and 4, etc., etc. 93 00:06:05.500 --> 00:06:09.500 So now I'm going to go for 3 and see what happens 94 00:06:09.500 --> 00:06:13.500 now, and we can go straight on and try 95 00:06:13.500 --> 00:06:17.500 To Sphere. So Shift, Alt, and 96 00:06:17.500 --> 00:06:21.500 S, and as we move the mouse to the left and right, 97 00:06:21.500 --> 00:06:25.500 we can see at 0 it remains a hexagon shape. But now as 98 00:06:25.500 --> 00:06:29.500 we approach 1, if you look in the lower-left there, as it goes 99 00:06:29.500 --> 00:06:33.500 up towards 1, we get a lovely circle in our mesh. 100 00:06:33.500 --> 00:06:37.500 Brilliant! That's exactly what we want! So let's hop straight into Face 101 00:06:37.500 --> 00:06:41.500 Mode again, and select these six slices of that pie, 102 00:06:41.500 --> 00:06:45.500 and try pushing that into the model, and let's see what's happens. 103 00:06:45.500 --> 00:06:49.500 Let's go into Object Mode to remove all that. 104 00:06:49.500 --> 00:06:53.500 So we're almost there but it still looks horrible! It looks now like 105 00:06:53.500 --> 00:06:57.500 it's a circle cut, but we're seeing the extra 106 00:06:57.500 --> 00:07:01.500 geometry, the hexagonal geometry around it, or the 107 00:07:01.500 --> 00:07:05.500 series of triangles that make that up. So we need to do one more step to make that 108 00:07:05.500 --> 00:07:09.500 nice and neat. So if we hop back into 109 00:07:09.500 --> 00:07:13.500 Edit Mode and undo that step, we can do 110 00:07:13.500 --> 00:07:17.500 one final thing and that is insetting this 111 00:07:17.500 --> 00:07:21.500 by a little bit, before we then extrude 112 00:07:21.500 --> 00:07:25.500 inwards. Now, once we've done that and we hop back 113 00:07:25.500 --> 00:07:29.500 over, we see that that nasty geometry surrounding the hole 114 00:07:29.500 --> 00:07:33.500 has gone. So by insetting, we have given it the opportunity 115 00:07:33.500 --> 00:07:37.500 to not look so horrible. OK, I think 116 00:07:37.500 --> 00:07:38.833 it's challenge time! 117 00:07:38.833 --> 00:07:42.833 OK, so I'd like you to create the next two circles we need! 118 00:07:42.833 --> 00:07:46.833 So if you have done it, undo the extrude into 119 00:07:46.833 --> 00:07:50.833 the sphere. We're going to deal with that, in a moment, so it's correct. 120 00:07:50.833 --> 00:07:54.833 Then, we're going to create two more holes, 121 00:07:54.833 --> 00:07:58.833 and then, using reference materials, just so you get the 122 00:07:58.833 --> 00:08:02.833 hole positions right... So use reference materials to 123 00:08:02.833 --> 00:08:06.833 guide their placement. Pause the video now and give that 124 00:08:06.833 --> 00:08:10.833 a go! OK guys, welcome back! 125 00:08:10.833 --> 00:08:13.233 Let's hop over into Blender! 126 00:08:13.233 --> 00:08:15.233 Alright, so we have our 127 00:08:15.233 --> 00:08:19.233 one hole here, and I'm simply going to 128 00:08:19.233 --> 00:08:23.233 go a bit further up and I'm going 129 00:08:23.233 --> 00:08:27.233 to put two more holes... Let's see, 130 00:08:27.233 --> 00:08:31.233 they have to converge relatively close to one another. 131 00:08:31.233 --> 00:08:35.233 So designs, decisions, design 132 00:08:35.233 --> 00:08:39.233 decisions. So I'm going to pop it in 133 00:08:39.233 --> 00:08:43.233 Perspective Mode, I think, just so I can get an eye on the ball. 134 00:08:43.233 --> 00:08:47.233 Yeah! That's going to be about right there! So we can see the line 135 00:08:47.233 --> 00:08:51.233 coming up here, so no it won't be there, not at all. 136 00:08:51.233 --> 00:08:55.233 It's probably going to be there and there. 137 00:08:55.233 --> 00:08:59.233 Now, that looks far too close together! If you look at 138 00:08:59.233 --> 00:09:03.233 reference materials and pins, that just won't look right. So 139 00:09:03.233 --> 00:09:07.233 let's remove that, and that one, well I'll keep that as a reference 140 00:09:07.233 --> 00:09:11.233 because I will need, that 141 00:09:11.233 --> 00:09:15.233 will be the lower triangle of the next set that I can possibly use. 142 00:09:15.233 --> 00:09:19.233 So that one there and that one there, and let's 143 00:09:19.233 --> 00:09:23.233 follow the line down. No, I've got that wrong! I'm blind as a 144 00:09:23.233 --> 00:09:27.233 bat, when it comes to this obviously! Let's zoom in a little 145 00:09:27.233 --> 00:09:31.233 further and see if we can actually get things lined up. So there will be a flat 146 00:09:31.233 --> 00:09:35.233 edge coming up here, so the next available one 147 00:09:35.233 --> 00:09:39.233 is that one there and this one here. 148 00:09:39.233 --> 00:09:43.233 Now you can see what I'm getting at there! I'm just trying to make sure that it's lined up appropriately, 149 00:09:43.233 --> 00:09:47.233 and actually, that one looks a bit too 150 00:09:47.233 --> 00:09:51.233 far apart. So is there anything in the middle of this one here and that one 151 00:09:51.233 --> 00:09:55.233 there? Nope, so I'm going to leave it like that for 152 00:09:55.233 --> 00:09:59.233 the moment. Now, because I've selected them both at once, you can do this 153 00:09:59.233 --> 00:10:03.233 by the way, so we can inset at the same time. 154 00:10:03.233 --> 00:10:07.233 Now I cannot remember how far I inset 155 00:10:07.233 --> 00:10:11.233 before, so I'm just going to do it by eye. That looks about 156 00:10:11.233 --> 00:10:15.233 right, and now, we need to select 157 00:10:15.233 --> 00:10:19.233 those two edge loops. Let's try and do everything in 158 00:10:19.233 --> 00:10:23.233 one fell swoop here. So that one and that 159 00:10:23.233 --> 00:10:27.233 one. Great! I'm now going to subdivide those, 160 00:10:27.233 --> 00:10:31.233 so we go to Subdivide, and we set them to 3 which is 161 00:10:31.233 --> 00:10:35.233 great! We can do that! Now, with 162 00:10:35.233 --> 00:10:39.233 them both selected, I'm not sure, at this point, if it's going to 163 00:10:39.233 --> 00:10:43.233 sphere correctly. No it's not! 164 00:10:43.233 --> 00:10:47.233 you see there, it's doing something weird, so we are going to have to select these 165 00:10:47.233 --> 00:10:51.233 individually. So let's select this edge loop here, and then, go 166 00:10:51.233 --> 00:10:55.233 To Sphere and wack that up to 167 00:10:55.233 --> 00:10:59.233 1, so it's 100% spherized. 168 00:10:59.233 --> 00:11:03.233 And now, just select this one and do the same so it's 169 00:11:03.233 --> 00:11:07.233 Shift, Alt, S, or you can go Spacebar, To Sphere. 170 00:11:07.233 --> 00:11:11.233 And there we go, we've got our next circle! 171 00:11:11.233 --> 00:11:15.233 And of course, my instruction before was to undo your extrude here. 172 00:11:15.233 --> 00:11:18.666 So if you haven't done that, what can you do? 173 00:11:18.666 --> 00:11:21.533 In fact, what we will do in the 174 00:11:21.533 --> 00:11:25.533 next lecture is correct that, as if you had made this mistake. 175 00:11:25.533 --> 00:11:29.533 That's absolutely fine! And I shall see you very shortly!
