WEBVTT 00:00.270 --> 00:03.080 Welcome to altering curve resolution. 00:03.150 --> 00:07.560 In this video we're going to be culling unnecessary geometry. 00:07.590 --> 00:11.850 Now we've kept the curve data itself so we actually have two options. 00:11.850 --> 00:19.170 In this case we can recreate our mesh object from those curves or we can fiddle about with the geometry 00:19.170 --> 00:20.240 itself. 00:20.520 --> 00:26.000 Now this is a prime example of when we've produced something that is basically too high poly. 00:26.100 --> 00:28.170 And there are a couple of ways of going about it. 00:28.170 --> 00:32.350 Now of course if you've managed to create it perfectly the first time round. 00:32.400 --> 00:33.030 Great. 00:33.030 --> 00:34.840 That is absolutely brilliant well done. 00:34.950 --> 00:41.280 However if you a mere mortal like me and the rest of us then occasionally you will end up making something 00:41.340 --> 00:47.460 that doesn't quite fit what you wanted in the first place and you'll have to go back and rework it. 00:47.460 --> 00:54.300 In fact in this section we do that a few times once we've explored the way to go so that's that's absolutely 00:54.300 --> 00:54.570 fine. 00:54.570 --> 00:59.080 That's part of the fun of learning and moving about within blender. 00:59.100 --> 01:01.070 So which path to take. 01:01.080 --> 01:06.510 Well both are okay it does depend on the stage of construction your rat and we're right at the beginning 01:06.510 --> 01:12.800 this time and in fact will be altering the curve resolution and the mesh itself to tidy it up. 01:12.810 --> 01:17.040 And of course after we've done that we're going to tidy up the rest of the geometry as well just to 01:17.040 --> 01:19.560 make it a little bit easier to work with. 01:19.830 --> 01:22.900 So let's hop straight on over into blender. 01:23.900 --> 01:24.170 Right. 01:24.170 --> 01:30.350 So looking at the base that we've currently created as you can probably see there's an awful lot of 01:30.650 --> 01:32.130 faces here in feathers. 01:32.150 --> 01:37.220 In my opinion far too much detail in this model I mean it's absolutely fine as a model goes. 01:37.220 --> 01:43.280 But if we in any mesh object that you have you re hop over into edit mode we can actually see the number 01:43.280 --> 01:46.370 of triangles that it is in it's seven hundred. 01:46.370 --> 01:51.560 Just in the base and I think that's a little over the top especially as we can employ other techniques 01:51.560 --> 01:54.190 later to smooth it out if necessary. 01:54.200 --> 01:59.670 Now we have a couple of options in which to do this basically. 01:59.870 --> 02:06.860 And we'll go in to first of all modify the curve that we've done and recreate our lamp base. 02:06.950 --> 02:11.100 So the first thing we'll need to do here is go in to the kerb. 02:11.100 --> 02:17.150 So first of all mcgurn to unchildish them by clicking on the icon that's important not the name but 02:17.150 --> 02:22.580 the icon itself moving to the left and we see it there it says drop to clear parents. 02:22.630 --> 02:24.230 I'm going to do that there. 02:24.290 --> 02:30.150 So now that's removed from our mesh so I'm just going to hide the mesh for the moment bring it out of 02:30.150 --> 02:32.960 the view by clicking on this. 02:32.970 --> 02:40.700 I just hear and of course we can't hide that until we're not editing it so let's go back into object 02:40.730 --> 02:42.830 mode and just hide the lamp base. 02:42.840 --> 02:49.850 Of course nothing's changed here because we've still got our curve based object just here. 02:49.850 --> 02:53.590 So let's go to the curve outline. 02:53.680 --> 03:00.860 She is this one over on the left hand side and skowron to widen my view here turn off the tall shelf. 03:00.860 --> 03:02.500 Probably bring this in just a little. 03:02.510 --> 03:04.430 Not completely but just a little. 03:04.430 --> 03:05.110 There we go. 03:05.360 --> 03:12.920 So in the curve propertys this data section here that we've been working on before we can change this 03:12.920 --> 03:19.100 resolution so we can see it's currently set to 12 and we can see what type of effect it has some of 03:19.100 --> 03:20.980 its tone that down a little. 03:20.990 --> 03:26.720 Because this resolution actually controls how many of seats are made. 03:26.870 --> 03:30.550 Once this is converted into an object itself. 03:30.590 --> 03:35.330 So with one we end up with a very angular model as you can see there. 03:35.420 --> 03:42.760 In fact what I'm going to do at this point is turn on or rather off smooth shading. 03:42.760 --> 03:47.370 So if we go to a flat we can actually see how things are working out. 03:47.400 --> 03:49.140 Let's go here flat shading. 03:49.170 --> 03:50.870 That gives us a much better idea. 03:50.880 --> 03:58.250 So I needed to select the base curve at the top here before in the tool shelf clicking flat shading. 03:58.250 --> 04:02.660 Now we can see what's really happening underneath of the underlined geometry. 04:02.870 --> 04:06.810 And let's go back to our outline curve. 04:06.950 --> 04:15.770 So as we increase that we will see our model changing as we can see at certain point we're at 12 before 04:16.190 --> 04:17.730 it ends up quite smooth. 04:17.860 --> 04:24.890 And as we go back again we can get an appreciation of at which point we no longer need to go. 04:24.890 --> 04:32.170 So at the moment it looks like four or five or maybe even six. 04:32.180 --> 04:36.730 I'm going to go for five in this case because I think it defines the shape well enough. 04:37.160 --> 04:44.480 And of course we've got the Bezier circle as well now because this has four points on ends and it's 04:44.480 --> 04:52.240 got a resolution at 12:00 a.m. It actually makes a circle of 48 segments which is four times 12. 04:52.540 --> 05:02.000 Now usually a 24 or 32 makes a good number of segments for a circle to keep it smooth. 05:02.000 --> 05:08.530 When you look at it so let's just see if we set it to six which would be twenty four. 05:08.600 --> 05:12.070 I think there might still end up looking a tiny bit jagged. 05:12.180 --> 05:17.840 So just up to eight which will equal the 32 because I'm quite happy with it being 32 or no that's going 05:17.840 --> 05:22.000 to produce a nice smooth circle type shape. 05:22.010 --> 05:22.490 Brilliant. 05:22.490 --> 05:29.480 So that's now done that now all we need to do is change these curves once again into a mesh object. 05:30.920 --> 05:32.750 Oh hey guys it's Challenge time. 05:32.750 --> 05:36.250 I'd like you to lower the triangle count of the base. 05:36.260 --> 05:39.890 So we're going to lower the resolution of the kerbs to an appropriate amount. 05:39.890 --> 05:45.840 Now we've already done some of that in the previous explanation about lowering those. 05:45.980 --> 05:51.830 But I would like you to experiment with it see how low you can go without losing the definition of the 05:51.830 --> 05:52.460 shape. 05:52.550 --> 05:58.670 I would like you to create a mesh object from the new lower rez curves and then finally once that mesh 05:58.670 --> 06:04.150 objects is created You're going to find that there are some places with in the hole itself. 06:04.220 --> 06:10.730 So I'd like you to remove the extra geometry from within the hole and I recommend using bridging edge 06:10.730 --> 06:12.120 loops for that. 06:12.140 --> 06:15.120 So go play the video now and give that a go. 06:17.360 --> 06:17.980 Okay guys. 06:17.990 --> 06:18.980 Welcome back. 06:19.010 --> 06:21.430 Let's hop back on over in a blender. 06:23.820 --> 06:31.590 Okay so over in that blender I'm quite happy with the resolutions that I've picked of eight for the 06:31.590 --> 06:35.700 actual circle the defining circle and the Bezier curve itself. 06:35.700 --> 06:39.320 I'm happy with five I think that gives enough definition for us. 06:39.420 --> 06:47.910 So I'm going to click on the base curve itself and go and press out and see and make a mesh from the 06:47.910 --> 06:49.360 curve objects. 06:49.710 --> 06:51.290 Brilliant we've got all that there. 06:51.280 --> 06:54.400 I'm going to keep the original of course that will make it disappear. 06:54.650 --> 07:02.100 So we hop into the undo history get down to where we switched into edit mode I think that's where it 07:02.100 --> 07:04.090 was excellent. 07:04.260 --> 07:10.650 And repeat the task again and this time we will keep the original because I do want to keep those curves 07:10.650 --> 07:12.350 just in case something like this happens. 07:12.540 --> 07:19.030 I'm going to immediately set the parent object as this new one and I'm going to call this lamp base 07:19.080 --> 07:22.370 and I'd feel quite happy now with deleting the old one. 07:22.470 --> 07:27.060 How you can see the difference there one smooth shaded So that's not a very fair comparison. 07:27.060 --> 07:33.210 So that's Turner's move shading and we can see that the difference between that and that is not that 07:33.210 --> 07:34.620 much at all. 07:34.620 --> 07:35.230 Brilliant. 07:35.280 --> 07:42.900 So I'm happy to delete the lamp base or in the process of preserving stuff I will hide it from view 07:42.900 --> 07:45.170 and everything else it's not being rendered. 07:45.260 --> 07:49.150 I'm going to shift it up and nestle it all the way under. 07:49.380 --> 07:51.210 It's called base curve at the moment. 07:51.330 --> 07:56.910 But this will become the new lamp base and therefore we've not lost anything in case I want to use that 07:56.910 --> 07:58.690 again later on. 07:58.980 --> 08:04.950 Okay so now that we've got our mesh object there I'm going to hop on over into edit mode and I'm quite 08:04.950 --> 08:08.540 happy with the level of detail that's here because it keeps the curves. 08:08.580 --> 08:09.620 That's absolutely fine. 08:09.630 --> 08:16.110 The base looks like it's got a few extra bits that are unnecessary so we can remove a couple of the 08:16.170 --> 08:18.200 edge loops that are going round the hair. 08:18.210 --> 08:19.590 It's not going to be deformed. 08:19.650 --> 08:22.620 So let's do that first because that's going to be the easiest one to deal with. 08:22.620 --> 08:27.840 I'm going to get rid of our back drop so we can actually see the base of our object. 08:27.960 --> 08:34.710 And I'm going to select with Edge select turned on and select these edge loops whilst holding down shift 08:34.710 --> 08:35.580 as well. 08:35.740 --> 08:40.430 Well select the wrong one sometimes happens. 08:40.480 --> 08:42.200 Let's just start again so let's. 08:42.330 --> 08:44.320 That edge there that one. 08:44.340 --> 08:47.790 That one I'm going to zoom in so I don't make that one up. 08:47.790 --> 08:48.480 There we go. 08:48.480 --> 08:49.860 So I'm happy with that. 08:49.860 --> 08:50.960 I'm going to. 08:53.130 --> 09:00.030 I'm going to have to leave actually the inside one because these stop here in a point some going to 09:00.870 --> 09:02.070 select that one. 09:02.070 --> 09:05.020 That one and that one there. 09:05.040 --> 09:05.550 That's fine. 09:05.550 --> 09:08.120 So then delete the vertices. 09:08.110 --> 09:09.950 They're someone that completely gone. 09:10.170 --> 09:18.770 And now I'm going to selects this edge here and this edge on the inside and. 09:19.820 --> 09:27.620 Go and search for bridging edged loops only use the space bar to bring that up amperage edge loops. 09:27.620 --> 09:28.100 There we go. 09:28.100 --> 09:31.130 So we've got a nice flat bottom going on there. 09:31.130 --> 09:35.600 There appears to be a bit of a geometry funny bit of geometry going on we'll have a look of that in 09:35.600 --> 09:36.850 the moment. 09:36.890 --> 09:39.810 That may be something else still turned on. 09:40.750 --> 09:41.980 Let's go and have a look. 09:41.980 --> 09:46.390 There doesn't appear to be some funny artefacts going on there. 09:46.390 --> 09:52.750 Let's see if there's any extra geometry some highlight the entire model and remove doubles for us to 09:52.740 --> 09:59.180 see okay that's removed 30 vertices which is useful especially when we're trying to lower the lower 09:59.190 --> 10:01.490 the triangle count. 10:01.540 --> 10:03.890 I'm not quite sure what's going on there. 10:03.940 --> 10:11.110 So I've had a look at the model and is unbelievably simple what's gone on why I've still got my curve 10:11.200 --> 10:13.920 object actually visible. 10:13.930 --> 10:16.720 I thought I'd turned it off but I obviously haven't. 10:16.720 --> 10:18.600 So let's go into that now. 10:20.690 --> 10:21.620 Have we go down here. 10:21.620 --> 10:24.930 The base outline and the base curve are still showing. 10:24.930 --> 10:27.650 That's going to confuse even me at this point. 10:27.650 --> 10:28.140 So there we go. 10:28.140 --> 10:30.350 Now we found out what's causing that. 10:30.360 --> 10:33.540 We can go in and go back to our meche objects. 10:33.540 --> 10:35.040 We should be able to see the inside. 10:35.040 --> 10:37.220 That's what I was expecting to see. 10:37.350 --> 10:40.920 And I'm literally going to feel this outside face. 10:40.920 --> 10:41.820 There you go. 10:41.880 --> 10:44.480 That's the bottom bit sorted now. 10:44.510 --> 10:51.540 Up here we have a series of faces running around here that aren't necessary. 10:51.540 --> 10:52.940 It's a single tube. 10:53.100 --> 10:58.330 We don't need all that extra geometry because it's not deforming or changing shape around that. 10:58.860 --> 11:04.890 So let's go in and I'm inside the model now as you can see are assumed in enough so I can see inside 11:04.920 --> 11:10.590 the model and that's exactly where I want to be because I want to select in face select I want to select 11:10.590 --> 11:12.460 this face loopier. 11:12.630 --> 11:13.730 This one here. 11:15.410 --> 11:17.360 This one here and that's it. 11:17.360 --> 11:21.890 I don't wanna slit top or bottom one because when I delete the vertices it'll actually delete these 11:21.890 --> 11:24.140 faces at the top and bottom as well. 11:24.140 --> 11:30.770 So when I go X and delete the vertices it's actually left this with this here which is brilliant because 11:30.770 --> 11:37.200 at the top we can select that edge loop there and then we can bridge the edge loops again. 11:37.460 --> 11:40.250 And that creates far less geometry. 11:40.280 --> 11:47.600 In fact we're now down to only or just under eight hundred triangles and that's a huge drop from what 11:47.600 --> 11:48.900 we were on before. 11:49.820 --> 11:56.490 Okay so I can guess here that a few of you a yelling at the screen go in Mike why haven't you just use 11:56.520 --> 11:59.870 dissolving ages to get rid of those and you're quite right. 11:59.870 --> 12:00.880 Why didn't I. 12:01.070 --> 12:03.810 That's because I'm human unfortunately. 12:03.880 --> 12:04.240 Yes. 12:04.280 --> 12:10.670 Dissolving edges in this case may have been a more efficient way of doing this particular cut down of 12:10.670 --> 12:11.350 polygons. 12:11.480 --> 12:16.780 Unfortunately for some reason my mind wasn't thinking about that so I chose a different direction. 12:16.790 --> 12:21.470 It just goes to show that blender is very versatile in the way that you approach it because there are 12:21.470 --> 12:26.780 always going to be several solutions and you will find that as these sections get increasingly more 12:26.960 --> 12:32.900 complex there will be more than one way to do some of it so don't worry if you went around and dissolved 12:32.900 --> 12:35.060 edge loops and Thall might didn't do it that way. 12:35.060 --> 12:35.770 Don't worry don't. 12:35.780 --> 12:37.100 Seriously do not worry. 12:37.160 --> 12:40.150 You have done it correctly I have done it correctly. 12:40.220 --> 12:44.430 You might have done it quicker for me though but that is a great thing to do. 12:44.690 --> 12:47.500 And whatever way you took do share that work. 12:47.510 --> 12:53.680 In the discussions so I can see how you're getting on and tell me how did you do it. 12:53.870 --> 12:56.380 And I will see you in the next lecture.
