WEBVTT 00:01.340 --> 00:05.430 Welcome to using curves to create a geometry. 00:05.720 --> 00:11.290 So in this video we're going to be using curves and this makes it infinitely editable. 00:11.450 --> 00:17.640 Now that basically means because a curve is a vector object it's not really it has a beginning point 00:17.660 --> 00:21.930 an end point but it's an infinitely calculable object. 00:22.010 --> 00:29.930 In our scene it also means that our mesh when we generate it using this method is infinitely ball too. 00:29.960 --> 00:36.590 Now this is only going to a tie apply to certain types of modelling but it is incredibly powerful. 00:36.590 --> 00:40.220 Now we're going to be changing the Bezier handle type as well. 00:40.220 --> 00:46.850 We haven't done that before but that will allow us to create sharp edges in our models and also generate 00:46.850 --> 00:47.840 a 3D object. 00:47.840 --> 00:49.970 By defining these curves. 00:49.970 --> 00:52.120 So let's hop over into blender. 00:57.150 --> 00:57.550 Okay. 00:57.560 --> 01:01.370 So over in blender I've opened up a brand new blend file. 01:01.580 --> 01:07.880 And I have noticed that for some reason in the past tub's saved my brandley blender file with the 3D 01:07.890 --> 01:10.120 kerson nowhere near the centre. 01:10.130 --> 01:11.620 Some are going to sort that out. 01:11.630 --> 01:14.340 Now I'm going to send to the 3-d cursor. 01:15.410 --> 01:16.310 There we go. 01:16.310 --> 01:22.690 And I'm just going to go and save my start-up file and go file new reload start off. 01:22.700 --> 01:23.540 Brilliant. 01:23.600 --> 01:26.930 That's been causing me a few headaches recently and I didn't realize what I'd done. 01:26.930 --> 01:31.830 Anyway back to the task at hand so let's get rid of the cube that's there. 01:31.970 --> 01:39.180 So that's the lead That's And we're going to need to add two curves to our scene. 01:39.190 --> 01:45.670 So first of all let's add a curve that's a type circle over in the outlying. 01:45.670 --> 01:50.560 I know it's one in radius but that's fine for this purpose in the radius. 01:50.570 --> 01:57.170 I'm going to call this a path because that's going to be the path at which our next curve is going to 01:57.170 --> 01:58.100 follow. 01:58.580 --> 02:04.670 So let's generate our other curve by adding another car but just the busier curve and that's going to 02:04.670 --> 02:06.400 add it right on top but that's okay. 02:06.560 --> 02:09.820 We're just going to shift that out of the way over here. 02:11.590 --> 02:12.550 Excellent. 02:12.550 --> 02:19.660 Now the next thing I'm going to do is unschooling to literally rotate it by 90 degrees on the x axis 02:20.020 --> 02:26.910 so that it rotates by 90 degrees on the x axis as constrained to X and 90. 02:27.040 --> 02:30.500 And the reason we're doing that would become quite apparent in a moments. 02:30.550 --> 02:34.120 In fact I've moved it along the wrong axis here. 02:34.240 --> 02:38.350 I actually just want to move it to one side of the circle. 02:38.350 --> 02:41.660 Now I'm going to view everything from the front. 02:41.780 --> 02:43.620 So I want to be in perspective. 02:43.620 --> 02:50.230 You know I don't I want to be an offer graphic view and looking at it from the front so we could see 02:50.260 --> 02:57.530 our circles just here and our curve our outline so we would just call that outline now. 02:58.320 --> 03:01.260 Of course you can choose to group these together if you want. 03:01.330 --> 03:05.640 So our curve and our outline are there and we're going to flip around again to the front of you because 03:05.640 --> 03:08.020 I've just moved away from it and zoom in a little. 03:08.340 --> 03:14.090 I'm going to hide tool shelf and the properties panes I can see what's going on. 03:14.430 --> 03:20.820 So we're going to introduce a new section now in blender and that's the data properties. 03:20.820 --> 03:27.390 So we've got all of the options along here in the properties panel and next to the spanner is a what 03:27.390 --> 03:34.240 looks like a path really and that's the data we hover over it is says object data. 03:34.320 --> 03:38.940 So we're going to hop into that and have a look at some of the options there. 03:38.940 --> 03:42.190 Now we're interested in is bevell object. 03:42.360 --> 03:50.220 So what we're going to do is select the path and select the bevel object as this curve over here the 03:50.280 --> 03:51.440 outline. 03:51.840 --> 03:55.110 So if we select that well we've got something straight away. 03:55.110 --> 03:59.880 And what we've got is this outline going around our circle. 03:59.940 --> 04:03.360 Now when we're in objet mode it doesn't matter where we put this. 04:03.360 --> 04:08.940 We can move it and it doesn't adjust our model over here at all. 04:08.940 --> 04:10.250 What's happening. 04:10.260 --> 04:16.440 Well if we go and grab in edit mode and start doing the same thing it does make a difference. 04:16.450 --> 04:22.500 Do bear that in mind when you're editing now because it's following this path around a circle of course 04:23.040 --> 04:26.880 the distance between the first point and the other point here. 04:26.990 --> 04:30.970 If we go beyond that it will the model itself will go through itself. 04:31.140 --> 04:36.620 So we go and extrude this point here you can see it's creating a nice vase like shape. 04:36.750 --> 04:42.240 But what's happening is the geometry is passing through itself and we don't want that to happen. 04:42.240 --> 04:48.760 However what we can do is drag this other bit as far out as we want without that being a problem. 04:48.840 --> 04:56.070 So if we lift this area up here and just do a bit of manipulation on our model we can make sure that 04:56.100 --> 04:59.010 the model itself is not going through itself. 04:59.010 --> 05:02.980 So if we move in we can now see because there's a hole in the top. 05:03.030 --> 05:06.220 We can definitely see that it's starting to work. 05:06.220 --> 05:09.780 Now I'm going to hop back over to the front view to see how it's looking. 05:10.020 --> 05:10.830 Well that's rather good. 05:10.830 --> 05:13.190 In fact that's kind of like a lamp isn't it. 05:13.190 --> 05:17.220 You could just imagine the bulbs sitting on top there. 05:17.490 --> 05:19.770 That may be useful later on of course. 05:19.770 --> 05:26.280 So vector's Now these can be a bit of a tricky one to see sometimes but when you make these handles 05:26.280 --> 05:32.850 the bit that you move the direction of your curve around with when you move those about They've got 05:32.850 --> 05:37.090 different properties and over in the tool shelf or when you press the V key. 05:37.110 --> 05:43.720 So the area down here is under handles or when you press the V key you can actually change the handle 05:43.760 --> 05:49.200 type and Vector means you get a straight and flat edge. 05:49.200 --> 05:56.650 Now theres not enough detail basically in the curves so we can see this really working well. 05:56.790 --> 06:03.370 But if I now go to here you see there theres a sharp edge before it curves back round again. 06:03.540 --> 06:06.460 We may need a few additional curves to make. 06:06.460 --> 06:09.640 Thats a really defined flat edge. 06:10.020 --> 06:13.020 So thats really powerful for making no end of things. 06:13.020 --> 06:18.370 It now looks like the beginnings of a jetfighter engine or something along those lines. 06:18.390 --> 06:19.940 I make that really pointy. 06:20.430 --> 06:25.140 What's it called a MIG or something along those lines and pull this handle here pull it right down. 06:25.140 --> 06:30.950 It looks like a MIG make me 17 or something along those lines or lightning. 06:31.090 --> 06:32.620 A British British lightning. 06:32.640 --> 06:34.830 Yes definitely. 06:34.900 --> 06:37.440 I'm going to pull up an image of one of those now. 06:38.280 --> 06:45.030 There you go guys one of those cold war beasts the interceptors there the girls started making the nose 06:45.030 --> 06:46.130 cone for one of those. 06:46.130 --> 06:47.230 How does that look. 06:47.310 --> 06:48.420 Pretty sweet. 06:48.420 --> 06:52.920 Hey Anyway I've got a challenge for you guys. 06:52.980 --> 06:55.820 I would like you to create the lamp base. 06:55.980 --> 07:00.240 So go ahead now and create the lamp base using curves. 07:00.480 --> 07:04.800 Change the handle time to vector where straight edges are required. 07:04.830 --> 07:09.660 If you want any straight edges but there is definitely going to be one and that's where the lamp base 07:09.900 --> 07:17.220 connects to the rest of the lamp so you're going to have a hole at the top of the base where the rest 07:17.220 --> 07:19.800 of the lamps are going to slot into a circular hole there. 07:19.800 --> 07:23.200 So make sure that you use vectors around there. 07:23.220 --> 07:25.400 Everywhere else can just be curves. 07:25.410 --> 07:29.790 Remember to fill in the bottom of the lamp as well so you are going to have to go across and do some 07:29.790 --> 07:30.720 measurements. 07:30.870 --> 07:37.470 Were going to be setting the base as we know to one unit across cross so it's only going to be half 07:37.530 --> 07:40.390 a blender unit that you're going to be able to work with in. 07:41.940 --> 07:44.140 Pause video now and give that a go. 07:45.740 --> 07:46.530 Welcome back. 07:46.670 --> 07:50.570 Let's go and create the base of our lamp. 07:50.810 --> 07:58.010 So let's get rid of the lightning nose cone there and head over to our animated lamp. 07:58.010 --> 08:03.530 Right so we've got our place holder here and I'm going to leave it in our scene for a while simply because 08:03.530 --> 08:09.240 it's going to act as the base size so I know it's not going too far out. 08:09.530 --> 08:16.880 I am going to turn this plane off so it's not in the way so if I zoom out I can still see things and 08:16.880 --> 08:21.540 I'm simply going to hide this cone when it's not needed. 08:21.830 --> 08:30.290 But first of all I'm going to add a curve that's a circle and I'm going to make it a radius of I don't 08:30.290 --> 08:33.720 think it really matters one more set it's a point five. 08:34.040 --> 08:38.440 And I'm going to call that the base. 08:39.610 --> 08:42.700 I seem to have caps lock on but that's absolutely fine with me. 08:43.000 --> 08:48.300 And now I'm going to create another curve in object mode of course. 08:48.660 --> 08:55.010 That's a Bezier curve and I'm going to shift it to the side and rotate it I'm going to do it here. 08:55.030 --> 09:01.690 The rotation on the x axis by 90 degrees during the creation and I'm just going to shift over to one 09:01.690 --> 09:04.120 side so I can see what's going on. 09:04.120 --> 09:08.640 It has also helped there can undo and get back to it that the operator panel note. 09:08.660 --> 09:11.980 So let's just recreate that really quick curve Bezier. 09:12.000 --> 09:13.690 I do everything all at once. 09:13.710 --> 09:18.040 Adam Bezier of a radius of point five I can do that straight away. 09:18.280 --> 09:19.800 So I don't have to worry about measurements. 09:19.810 --> 09:23.990 And of course set the rotation on x axis by 90. 09:24.070 --> 09:24.970 Brilliant. 09:24.990 --> 09:27.530 We shift over to one side so we can see what's going on. 09:28.380 --> 09:31.240 Popover into orthographic and front view. 09:32.690 --> 09:36.280 I'm going to get this Bezier curve here called it outline. 09:37.660 --> 09:42.700 And I'm just going to place my outline under. 09:43.790 --> 09:48.270 The base itself so said parent object that's absolutely fine. 09:48.280 --> 09:50.180 So now those two things are linked together. 09:50.180 --> 09:52.970 So I've got some control over my hierarchy. 09:52.990 --> 09:56.160 I might have to start cleaning up all of that in a bit. 09:56.180 --> 09:58.550 Anyway so let's go into here. 09:58.550 --> 10:01.750 Let's go over to the data of it. 10:01.760 --> 10:04.370 And we need to make sure we've got the base selected. 10:04.370 --> 10:07.940 We're going to set the bevell object to outline. 10:08.000 --> 10:08.800 Excellent. 10:08.840 --> 10:11.030 You can already see it's too big. 10:11.300 --> 10:16.970 So I'm going to go over here to this and simply go into edit mode. 10:16.970 --> 10:18.230 Now we're in edit mode. 10:18.230 --> 10:20.000 We can have some control over this. 10:20.000 --> 10:23.740 And I'm guessing the reason why it's too big is this is between here and here. 10:23.960 --> 10:26.450 Happens to be one blender unit. 10:26.630 --> 10:30.100 So I'm going to move it straight away so I've got the right depth. 10:30.290 --> 10:35.840 I'm going to hop out of it maybe just move it across as a bit more space round to the front. 10:35.840 --> 10:39.050 In fact what we could do with here is splitting our windows. 10:39.070 --> 10:44.960 I'm going to split my window and hide the tool shelf hide these properties over here we're not going 10:44.960 --> 10:47.120 to hide them it's going to push them as far away. 10:47.150 --> 10:52.890 Again you may not have such a problem if you've got a larger monitor. 10:52.880 --> 10:59.900 I'm a bit constrained on space so you guys can see and I'm going to hop into this curve into edit mode 11:00.220 --> 11:04.740 and move this point here in the x-axis by point five. 11:07.010 --> 11:07.780 Excellent. 11:10.710 --> 11:13.000 Lift this one up. 11:13.110 --> 11:17.450 And now I'm inside the cone Seim going to select the cone itself. 11:19.080 --> 11:21.890 And press the H key to hide it away. 11:21.960 --> 11:27.090 So there we go we've got our rough base going in as a couple of things that we're going to have to do 11:27.090 --> 11:27.260 here. 11:27.280 --> 11:31.470 We're going to have to make sure that it all joins up and there's a slot in the top. 11:31.470 --> 11:33.830 And of course I'm nowhere near finished yet. 11:34.020 --> 11:42.540 So let's select these two areas here and add in a subdivide which is going to add another area in the 11:42.540 --> 11:47.410 middle that allow us to control the shape of the curve that little bit better. 11:48.650 --> 11:51.440 Not too worried about the shape at the moment. 11:51.440 --> 11:54.010 This one here I'm going to have to pull back now. 11:54.050 --> 11:59.730 I'm going to have to think of the size of the slots that the rest of the lamps are going to slot into. 11:59.900 --> 12:04.250 And whatever it is is going to be doubled because we're working on the radius. 12:04.250 --> 12:12.040 So I'm going to be moving that one in the minus X axis by let's say point 1 so it's a point two across. 12:12.050 --> 12:14.930 And let's see how that looks it might not work it might. 12:14.930 --> 12:15.800 Who knows. 12:15.800 --> 12:20.250 This is all about experimentation at this point and playing with our model. 12:20.300 --> 12:28.130 So let's grab that which we have done and move it in minus so x y minus point 1. 12:29.510 --> 12:34.060 Excellent so if we rotate this round we should end up with one set up dates. 12:34.060 --> 12:37.910 We should end up with a hole in the top. 12:37.910 --> 12:39.610 Come back to that in a few moments. 12:39.620 --> 12:45.710 Now we're going to have to have another point so we're going to let this end one end extrude and pull 12:45.710 --> 12:46.070 it across. 12:46.070 --> 12:50.630 We saw there was a problem or a delay in its updating there. 12:50.630 --> 12:55.310 Don't worry if that happens I don't want to be in front for you just in case if you're not in front 12:55.310 --> 13:03.950 view when you start doing this you're going to end up potentially with the curve going off in the well 13:04.380 --> 13:06.250 in the y plane in this case. 13:06.260 --> 13:07.450 And we don't want that. 13:07.470 --> 13:12.220 The position of this the we want it at. 13:13.050 --> 13:17.880 So we're going to have to open up this and make sure the local or the global local. 13:17.920 --> 13:21.450 That's what we do want in this case the exposition. 13:22.230 --> 13:25.500 Is point five I believe. 13:26.610 --> 13:26.940 Soon. 13:26.950 --> 13:27.680 BECK out. 13:29.300 --> 13:29.650 Yes. 13:29.660 --> 13:30.480 That's right. 13:30.560 --> 13:38.210 I'm going to have to change this one here to a vector that will flatten it out and probably change this 13:38.210 --> 13:44.850 one here but not both of the handles just the bottom one to vector and that should bring it round. 13:44.870 --> 13:47.770 So it's got a completely flat base. 13:47.810 --> 13:52.130 Now the top here we've also got a little bit of fiddling to do. 13:52.130 --> 13:54.970 It's getting really tight here on my screen. 13:55.000 --> 13:57.530 It's going to pull that one back across. 13:57.980 --> 14:00.020 So you guys can see what's going on. 14:00.020 --> 14:05.960 So down here we've got to move it down and in by once I'm going to move it down probably not move it 14:05.970 --> 14:06.280 sorry. 14:06.290 --> 14:12.210 I'm going to extrude from there downwards and I have this horrible curve initially. 14:12.530 --> 14:19.190 So let's move that one downwards by about there and we can alter the settings in here so the x coordinate 14:19.220 --> 14:25.270 is the local x that's going to be point four because that's point five minus point one that we did earlier. 14:25.280 --> 14:31.120 I'm going to go down by at least point two in this case so point two. 14:31.550 --> 14:32.250 Excellent. 14:33.390 --> 14:41.070 And then I'm going to hit V and go vector there so that straight I'm going to select this bet select 14:41.070 --> 14:45.590 just this handle here and change that also to vector. 14:45.600 --> 14:48.060 And we've got a straight spit going down. 14:48.060 --> 14:49.970 And then finally we need to go in. 14:49.970 --> 14:57.720 So I'm going to extrude here and it will remember this time that it is just a affecter which is great 14:58.080 --> 14:59.620 and we're going to move it in. 14:59.610 --> 15:04.220 So the X's point five The Y is point two. 15:04.490 --> 15:05.480 And there we go. 15:05.580 --> 15:06.790 That's perfect. 15:08.190 --> 15:10.880 The change is handled type again to vector. 15:11.050 --> 15:16.620 So it remains straight and let's have a look at our lamp base for the moment. 15:16.660 --> 15:17.810 I don't want it that tool. 15:17.830 --> 15:23.300 By the way it looks more like a a hatz at the moment than a base of our lamp. 15:23.410 --> 15:27.460 So let's hide some stuff so we can see what's going on. 15:27.460 --> 15:27.760 Right. 15:27.760 --> 15:34.480 So here we're probably going to have to lift this up but I don't know for the moment let's select all 15:34.480 --> 15:40.200 of this geometry here all of these curves vertices and just pull them down. 15:41.520 --> 15:43.310 And that's a bit better. 15:43.400 --> 15:45.950 And there's another point here this one here. 15:45.950 --> 15:51.010 Let's move about and see if we can get a slightly different shape going on. 15:54.550 --> 15:57.930 I quite I would like a little bit of a rich going round. 15:57.970 --> 15:59.090 I don't know why. 15:59.470 --> 16:00.220 You know it's just play. 16:00.250 --> 16:01.480 Oh that's interesting. 16:01.480 --> 16:03.850 I thought I'd applied them change and I hadn't. 16:03.850 --> 16:04.240 There we go. 16:04.240 --> 16:07.210 So let's have a look around our lamp. 16:07.740 --> 16:09.600 That's looking pretty good. 16:09.620 --> 16:11.340 I've got a hole in the top for the rest of it. 16:11.490 --> 16:15.070 Now that might be a bit Big actually for the rest of the lamp. 16:15.090 --> 16:18.310 That does look rather large so I can go out here and here. 16:18.630 --> 16:26.720 So let those two out individually that one them that one there and move them in x axis by point one. 16:27.130 --> 16:27.730 Oh no not. 16:27.760 --> 16:29.110 Point one I think that we'll see. 16:29.130 --> 16:29.830 It's up. 16:34.080 --> 16:35.560 Let's move them back. 16:35.690 --> 16:37.520 It's going to be half of point one. 16:37.540 --> 16:42.640 So move it in the x axis by point nor five. 16:45.610 --> 16:50.020 Looks like I didn't have the right thing select this let's just undo all of that. 16:50.170 --> 16:51.300 Right. 16:51.310 --> 16:52.360 That's going to move it. 16:52.360 --> 16:54.720 In fact I'll do it live here. 16:55.690 --> 16:56.670 Point five. 16:56.680 --> 16:58.510 Yeah that does look about right. 16:59.040 --> 17:05.000 Undo that move it's in the x axis by point 0 5. 17:05.320 --> 17:06.100 There we go. 17:06.340 --> 17:12.580 And for some reason it doesn't always update on here and it's worthwhile remembering that as that can 17:12.580 --> 17:14.490 be incredibly confusing. 17:14.530 --> 17:18.510 I've made it smaller Why hasn't it gone any smaller. 17:18.640 --> 17:23.110 It's always a good question but it does seem to catch up the moment you move something else which is 17:23.110 --> 17:24.630 a bit strange. 17:24.680 --> 17:26.400 I'm going to undo that change there. 17:26.440 --> 17:27.880 And there we go is updated now. 17:27.910 --> 17:31.880 I quite like the base of my lamp there looks pretty sweet. 17:31.900 --> 17:36.520 And of course we're going to take it through to the final end as we've been doing. 17:36.520 --> 17:40.720 So I'm just going to hide this oh I've just made another 3D view. 17:40.720 --> 17:41.650 Lovely. 17:41.830 --> 17:45.670 So I'm going to hide that away so we've just got one big view again. 17:46.180 --> 17:47.280 Excellent. 17:47.290 --> 17:49.200 Let's hop back into perspective. 17:49.320 --> 17:51.190 We get a better feeling for things. 17:51.400 --> 17:56.830 And then well let's render it let's see what it looks like when we render our image. 17:57.090 --> 17:58.530 Why is that going on. 17:58.630 --> 17:59.790 Of course. 18:01.480 --> 18:08.390 What you will find is if we change the view to camera it has a different box selected on it. 18:08.680 --> 18:16.120 And of course when we click render that's what it does so if we go Control out and be clear that we 18:16.120 --> 18:17.390 see the whole thing will render. 18:17.410 --> 18:21.280 And if we go to rended image and of course it's rendering our cone now. 18:21.320 --> 18:24.950 Why is it rendering our cone over in the outline. 18:25.120 --> 18:29.480 We have our camera here which is what we're looking for. 18:29.490 --> 18:34.260 And beneath we have our cone now is not visible in the 3D view probably is visible in rendering so if 18:34.270 --> 18:40.270 we turn that off and go back to rendering the image there we go we can see our model much better. 18:40.270 --> 18:44.940 Of course this is too far out so we can adjust our camera etc. but we do want to do that at the moment. 18:45.070 --> 18:51.580 For the moment we literally want to go back to the 3-d view of course we need to turn on our plane so 18:51.580 --> 18:53.810 we can see some stuff. 18:53.860 --> 18:54.670 Excellent. 18:54.700 --> 19:00.160 And then we can move around and this scene because it's now more complex I'm just going to let it run 19:00.160 --> 19:02.580 out now to see how long it's taking. 19:02.590 --> 19:07.700 Now we've got some much more geometry in it than just the simple comb we have before. 19:07.780 --> 19:14.440 It looks like it's going to take around 14 or exactly 14 seconds 15 set 15 and a half seconds it takes 19:14.440 --> 19:15.830 to do that basic render. 19:15.880 --> 19:21.370 Of course if we draw that box around it will talk that we were talking about earlier it's going to take 19:21.370 --> 19:23.470 considerably less time three seconds. 19:23.620 --> 19:30.830 So there's a great benefit even when you're on a reasonably fast computer to rendering it in that manner. 19:31.120 --> 19:31.690 Brilliant. 19:31.690 --> 19:32.710 How did you guys get on. 19:32.710 --> 19:40.330 I'd love to see your lamp base designs and how you managed to create it with the busy air curves there. 19:40.330 --> 19:44.390 Please share in the discussions and I will see you in the next lecture.
