WEBVTT 00:00.550 --> 00:03.480 Welcome to good meche topology. 00:03.490 --> 00:06.670 Now first of all what is meche topology. 00:06.670 --> 00:14.110 Will two objects can have the same shape themselves yet have a different mesh construction a different 00:14.140 --> 00:21.730 arrangement of polygons making those up topology can determine how easy it is to edit or animates an 00:21.730 --> 00:22.530 object. 00:22.540 --> 00:27.220 If you've made something out of triangles it's going to be a lot harder to edit if you've made something 00:27.220 --> 00:30.750 out of quads and we'll go through why in a bit. 00:31.800 --> 00:39.390 Now in general you said this before used quads wherever possible end ons and triangles would typically 00:39.390 --> 00:40.650 cause pinching. 00:40.650 --> 00:41.580 In your model. 00:41.610 --> 00:47.340 Now that's fine if it's hidden out of the way or on something that doesn't move or indeed where pinching 00:47.340 --> 00:52.980 is desired but often it's not desired we want to avoid it whenever possible. 00:53.160 --> 00:59.650 So let's go have a quick look at different apology's with the same shape and hop on over into a blender. 01:01.120 --> 01:06.790 So here we are in blender and I've got three layers all with three spheres on it. 01:06.790 --> 01:11.360 This is this simple example as I could possibly think of to demonstrate this. 01:11.380 --> 01:18.760 I've got Layer 1 2 and 3 as you can see the ball changes slightly in its shading etc. There may be a 01:18.760 --> 01:25.300 scaling issue there but they all look the same and you can't tell their construction by just looking 01:25.300 --> 01:26.740 at the shape. 01:26.740 --> 01:33.850 Now if I were to go into edit mode on this you see that this one is made up of quads all the way around 01:33.850 --> 01:41.810 it and what that means is if we're in face select mode I can start selecting rings around it very easily. 01:41.890 --> 01:49.710 These face loops going round without any problem whatsoever and that has a great impact when editing 01:49.710 --> 01:52.760 because you can edit a lot at once. 01:52.760 --> 01:58.430 If we have a look at perhaps one of the other spheres we have here the same on the second layer. 01:58.530 --> 02:00.070 By hop into edit mode. 02:00.070 --> 02:03.010 On this you'll see that it's a uv's Sphere. 02:03.100 --> 02:08.050 It comes to a pole at the top so similar to the last sphere. 02:08.050 --> 02:11.350 I can still select some rings going round. 02:11.350 --> 02:16.810 I can select the all these face loops going around here and the face loops going up and down but you'll 02:16.810 --> 02:24.460 notice that I can't reach the top or go all the way around so that one is almost as useful as the previous 02:24.460 --> 02:24.970 one. 02:24.970 --> 02:29.840 However you will notice that the squares themselves the quads aren't particularly. 02:29.860 --> 02:36.370 Even they change in size quite dramatically from these small narrow ones at the top to pretty square 02:36.370 --> 02:44.350 ones in the middle and if we hop over to the previous one you'll see that pretty much all of these quads 02:44.410 --> 02:47.470 are the same size across the entire model. 02:47.620 --> 02:50.710 And that also makes it nice and easy to model with. 02:50.710 --> 02:51.720 To work with. 02:51.880 --> 02:54.400 Especially if you're sharing files with other people. 02:54.400 --> 03:00.930 It's very important that we get topology right so someone else can pick it up and work with it. 03:00.940 --> 03:07.700 The final example I have here is a nother spear and you probably already guessing it is sent IKO sphere. 03:08.170 --> 03:12.200 Now this would be an absolute pain in the backside to try and work with. 03:12.320 --> 03:20.440 Because if we try and select any loops there aren't any because every single join is a pole and if we 03:20.440 --> 03:27.160 remember going back a pole is basically where edges joined together and we can see here there are 1 03:27.160 --> 03:35.650 2 3 4 5 6 joining this particular vertex here in the middle and Ideally we just want quads so the flow 03:35.650 --> 03:38.920 of edges goes round one way and round another. 03:38.920 --> 03:44.470 Now occasionally we can have five or three joining together will discuss that further along in this 03:44.470 --> 03:45.560 section. 03:45.580 --> 03:47.540 Now it's not all about quads now. 03:47.550 --> 03:55.840 Quads are very important but it's topology that defines a Faces key shape or any objects shapes the 03:55.900 --> 03:56.500 edges. 03:56.500 --> 04:04.060 In face loops will follow the general features around one's face or any particular object that your 04:04.060 --> 04:11.350 modelling loops will help with the editing and we'll see that in great detail coming soon and loops 04:11.410 --> 04:17.800 will help with defamation an animation so if you wanted to make your character smile or frown if you 04:17.800 --> 04:19.950 were trying to do it it was a triangular mesh. 04:19.960 --> 04:22.900 It would be a lot more difficult to do. 04:23.260 --> 04:28.200 Now I've got a couple of examples here all made with quads. 04:28.390 --> 04:34.670 Now on the left we have bad even though it's all made up with quads in general. 04:34.690 --> 04:39.870 None of these air edge loops or face loops follow the actual features of the face. 04:39.890 --> 04:46.630 If we have a look over on the right hand side we can see that the eyes are defined with a loop going 04:46.630 --> 04:47.410 round them. 04:47.560 --> 04:48.670 So is the mouth. 04:48.760 --> 04:50.800 In so is the whole face itself. 04:50.800 --> 04:53.090 And there's one on the ear as well. 04:53.090 --> 04:59.050 If we have a look at going a bit further from this so we're going as a very low poly model there. 04:59.080 --> 05:04.900 If we then go to the next step up you can see that these features are defined even more. 05:04.900 --> 05:07.240 There's a ring running round the nose. 05:07.240 --> 05:12.880 You can definitely see that in this second example here you can see the ones going Rammy eyes. 05:12.880 --> 05:17.290 There's one big one going around the cheeks and round the face. 05:17.290 --> 05:23.500 And of course the mouth is as a well is well defined by these rings or loops going round. 05:23.590 --> 05:27.910 And that is what's really important now can be quite challenging to do that and will go through the 05:27.910 --> 05:34.300 construction of each part of the face in detail and giving you some tools as we go but it's very important 05:34.300 --> 05:37.920 to realize that it's not all about quads. 05:37.930 --> 05:40.200 It's also how you arrange them. 05:41.050 --> 05:43.090 Okay guys it's Challenge time. 05:43.090 --> 05:46.140 I'd like you to go ahead and plan your topology. 05:46.420 --> 05:51.050 Now knowing how you're going to create your model is very important. 05:51.130 --> 05:53.200 So that's what this challenge is all about. 05:53.200 --> 06:00.400 I'd like to go and get your reference material and mark out the key features and draw on the main face 06:00.400 --> 06:05.680 loops running around your model balls a video now and give that a go. 06:08.870 --> 06:09.520 Okay guys. 06:09.530 --> 06:10.380 Welcome back. 06:10.550 --> 06:18.130 Let's go have a look at my reference material and let's have a look at where the facelifts will be. 06:18.470 --> 06:22.080 Okay so in front of us we have a photo of me. 06:22.250 --> 06:25.450 Now one of the key areas will be around the mouth. 06:25.460 --> 06:30.030 So let's go ahead and draw a loop around the mouth. 06:30.080 --> 06:32.720 Now there also be a loop around each eye. 06:32.720 --> 06:36.500 Now those are pretty well-defined and easy to spot. 06:37.340 --> 06:40.260 So there we go we've got the loops running around there. 06:40.310 --> 06:45.020 Now of course we've got another loop that defines the entire face itself. 06:45.020 --> 06:47.430 So we go all the way around. 06:47.620 --> 06:55.280 And we're mainly focussed on the front of our face at the moment so we've got one that runs around that 06:55.340 --> 06:55.900 area. 06:55.940 --> 07:03.010 There now because of planning these things it helps us work out how we're going to construct our model. 07:03.020 --> 07:06.290 Now the is we can't really see from this angle so I'm going to focus on those. 07:06.290 --> 07:12.320 There are a couple of loops that run around because it's in intertwining loop and the is quite complicated 07:12.320 --> 07:14.520 and will go home for that in more detail. 07:14.530 --> 07:22.190 Now the nose itself is going to be a loop that runs around the bottom around there around that sort 07:22.190 --> 07:22.920 of area. 07:23.030 --> 07:30.710 And there's one more loop as it runs along the top of the bridge of the nose around there and then runs 07:30.710 --> 07:34.980 down to the chin and back up again. 07:35.840 --> 07:41.600 And that helps us control our model because that encompasses all the areas where the muscles would be 07:41.600 --> 07:44.720 moving the skin underneath. 07:44.720 --> 07:50.990 Now this is our only one way of doing this if you weren't moving certain parts you wouldn't have to 07:50.990 --> 07:53.850 do all of this in the amount of detail you include. 07:53.860 --> 08:00.530 Again it will vary depending on the model you're doing going to make it quite a basic model to begin 08:00.530 --> 08:00.920 with. 08:01.070 --> 08:07.990 So then we can develop past skills without getting too deep and complicated and time consuming. 08:08.000 --> 08:14.250 Remember from the last section the more detail you need to do the longer it's going to take. 08:14.240 --> 08:21.590 And I would rather go through six or seven models and it take me a day or two to do than do one model 08:21.590 --> 08:27.260 it take me a week and I haven't learnt all of the skills by the repetition going through making these 08:27.260 --> 08:27.880 models. 08:27.920 --> 08:30.220 So don't be afraid to make more than one. 08:30.290 --> 08:34.770 So those are my loops that I'm going to concentrate on when I start making my model. 08:34.910 --> 08:36.860 How did you define your loops. 08:36.860 --> 08:38.330 Did you get all of these in here. 08:38.330 --> 08:40.140 Did you miss a couple. 08:40.190 --> 08:45.820 Were you surprised about the one that goes across the bridge or around the tip of the nose. 08:45.860 --> 08:47.090 Please share. 08:47.090 --> 08:51.540 As always in the discussions and I will see you guys in the next lecture.
