WEBVTT 00:00.450 --> 00:06.360 Welcome to the first lesson on organic modeling in this lesson, we're going to take a look at something 00:06.360 --> 00:07.440 called topology. 00:07.890 --> 00:11.820 These are some concepts you need to learn before we start modeling our own character. 00:12.070 --> 00:14.180 So you know why we're doing what we're doing. 00:14.610 --> 00:20.790 So topology essentially means the line flow or the edge flow. 00:22.060 --> 00:23.440 Over a surface. 00:24.160 --> 00:30.450 So when we look at a model like this, we see it in ingratiated form, but what makes up this model? 00:30.760 --> 00:35.670 This model is made up of if we right click, we can see faces, vertices and edges. 00:35.680 --> 00:36.910 Those are the three main things. 00:36.910 --> 00:42.880 And we kind of already know this from the hard surface modeling, but it's even more important to understand 00:42.880 --> 00:47.260 these concepts when we're doing organic modeling as well. 00:47.290 --> 00:51.070 So so let's take a look at the edge flow here. 00:51.070 --> 00:57.280 And we can do this by turning on the wireframe on shaded button here so we can see the object while 00:57.280 --> 00:57.790 it's shaded. 00:58.030 --> 01:02.020 We can't have for like we've done in the hard modeling, but then we see through the object. 01:02.030 --> 01:06.170 So it gets kind of confusing to see where the lines are split five to get that back. 01:06.550 --> 01:10.120 Also, a quick aside, if you want to change the background color hit Holtby. 01:10.600 --> 01:16.510 And I'd just like to keep it on blue because the default shaders gray, so it's easier to see the model 01:16.510 --> 01:16.920 on that. 01:17.320 --> 01:22.210 So when we look at this, we can see there's a lot of edges and they're all going in different directions, 01:22.660 --> 01:24.400 you know, more simple areas. 01:24.670 --> 01:27.010 It's pretty straightforward, like the arm. 01:27.310 --> 01:31.540 It looks like a cylinder and or just edges going across the arm as you'd expect. 01:31.930 --> 01:35.920 But what happens when that needs to be attached to a torso? 01:36.280 --> 01:41.450 We get an intersection of edges here and you can see that by this star, right. 01:41.620 --> 01:48.210 So if we look over here, all of these edges are intersecting with one other edge, right? 01:48.280 --> 01:50.290 There's one edge going this way, one edge going that way. 01:50.590 --> 01:54.160 But when we look at a star, we can see there's one edge going here. 01:54.160 --> 01:58.950 When it's going there, when it's going in, there's a lot more edges intersecting at a star. 01:59.230 --> 02:06.400 And what that tells you is this is where the line flow changes and it changes because it's having to 02:06.760 --> 02:12.490 deal with other line flow, you know, intersecting line flow that's doing something different and that 02:12.490 --> 02:15.110 gets resolved and something like a star shape. 02:15.550 --> 02:22.720 So the reason why that is conceptually is because you you have lines going in different directions that 02:22.720 --> 02:24.250 need to meet up and connect. 02:24.670 --> 02:31.550 And you also have lines or edges that are coming from an area of high density to low density. 02:31.960 --> 02:39.790 So if we look at the corner of the eye here, you can see that we have all of these edges coming from 02:39.790 --> 02:44.010 a larger area and they need to go into a smaller area like the eye. 02:44.560 --> 02:52.300 And what happens is you have to reduce the number of edges as you go in so that it sinks up with however 02:52.300 --> 02:53.830 many edges are on the inside. 02:54.280 --> 02:58.030 And so you can see that with something like a star again. 02:58.030 --> 02:58.360 Right. 02:58.630 --> 03:02.230 And this area right here is what I'm looking at. 03:02.770 --> 03:06.920 So this really looks like a triangle. 03:06.920 --> 03:10.990 If we just pulled this vertically up, this would be like a triangle, right? 03:12.050 --> 03:13.110 Something to go back to. 03:14.140 --> 03:14.860 Object mode. 03:14.860 --> 03:15.070 Right. 03:15.070 --> 03:20.710 Clicking So we have this edge, just dead ends, basically. 03:21.310 --> 03:26.470 But they pulled out the vertices so that it is more evenly distributed. 03:26.680 --> 03:27.130 Right. 03:27.130 --> 03:29.820 So that the edge flow looks like it kind of goes around the eye. 03:30.700 --> 03:37.480 So when we're doing organic modeling, the reason behind all this, too, is it so this works for animation. 03:37.840 --> 03:42.850 Whenever we deform something, we need the edge floater to work properly. 03:42.850 --> 03:47.740 Otherwise the deformation is going to look weird and I'll show you what that means. 03:47.740 --> 03:50.170 And another lesson, but just conceptual. 03:50.170 --> 03:53.920 We need to begin to understand why things are modelled the way they are. 03:54.100 --> 03:54.450 Right. 03:54.790 --> 03:57.990 And to know how to look at how things are modeled. 03:58.000 --> 04:01.530 So then we can break it down in our mind and recreate it. 04:01.810 --> 04:05.230 So if we keep looking at this model, we can see, look, here's another star right here. 04:05.680 --> 04:13.480 So we can see that if we take a look at the mouth edge flow, this section here, all of these lines, 04:13.480 --> 04:15.070 edges go around the mouth. 04:15.070 --> 04:15.670 And why is that? 04:15.670 --> 04:17.520 Because the mouth needs to open, right? 04:18.340 --> 04:20.340 So those edges need to be circular. 04:20.740 --> 04:21.130 All right. 04:21.130 --> 04:23.590 And they go out and they go out further and further. 04:23.830 --> 04:29.140 And then they meet edges that, you know, it no longer needs to go in a kind of circle around the mouth. 04:29.140 --> 04:31.650 It needs to start connecting to the nose and eyes. 04:31.930 --> 04:36.370 So now the edges need to go up towards the eyes and it needs to change direction. 04:36.370 --> 04:43.330 And that's where you get these stars, right where this edge that was now going up to the nose needs 04:43.330 --> 04:45.300 to be redirected into the eye. 04:45.610 --> 04:49.750 And so we get a star right here and that's usually where you see those intersections happening. 04:50.280 --> 04:52.570 OK, we can also see this with the eyes. 04:52.720 --> 04:58.480 There's kind of an eye mask area here and same thing with the mouth, right. 04:58.480 --> 05:00.310 Circles going around and around and around. 05:00.310 --> 05:03.460 And eventually they need to change direction and start connecting to everything else. 05:03.880 --> 05:05.350 So we get a star right here. 05:05.860 --> 05:08.260 OK, you can see how that edge flow changes. 05:08.260 --> 05:12.070 And now it goes down the the side of the cheek here and up the brow. 05:12.610 --> 05:17.860 So this is what you need to begin to understand about topology and why it's important and why we're 05:17.860 --> 05:21.190 going to model things the way we're going to model them so that they work in animation. 05:21.740 --> 05:26.150 So the next lesson I want to take you through some of the concepts of so the next lesson, I'm going 05:26.150 --> 05:33.920 to show you how to take areas of high density to low density and how to make these kinds of areas. 05:33.930 --> 05:35.410 We can see another one right here. 05:35.810 --> 05:40.100 So let's simplify this in the next lesson and learn how to do that. 05:40.340 --> 05:40.970 Thanks for watching.
