WEBVTT 00:00.180 --> 00:06.330 Welcome to pivot points in this video we're going to talk about pivot points and origins and how they 00:06.330 --> 00:07.180 interact. 00:07.230 --> 00:10.260 We'll take a closer look at pivot points. 00:10.260 --> 00:14.810 There are five different types and the how they vary when you're modelling. 00:14.820 --> 00:21.120 We'll talk about how to change them and go through the shortcut keys for them as well and things to 00:21.120 --> 00:26.670 watch out for when you're modelling pivot points are one of those tripping things that if you don't 00:26.670 --> 00:34.220 realize you've changed them or that you've set them incorrectly it can make modelling quite difficult. 00:34.230 --> 00:38.800 So let's go explore pivot points now and hop on over in a blender. 00:39.800 --> 00:43.730 Okay so in front of us we have a default blender file. 00:43.730 --> 00:49.520 And I just want to say quickly that this is an insert into the course because there have been several 00:49.520 --> 00:54.310 requests for pivot points to be covered a bit earlier on in the course. 00:54.350 --> 00:55.790 So that's what we're doing. 00:55.790 --> 01:02.720 And in this case we need to first find out where they are and if we go down to the 3D header toolbar 01:02.780 --> 01:06.320 we see there is an option for pivot points. 01:06.440 --> 01:13.250 And here we have a selection of five different pivot points active element median point individual origins 01:13.250 --> 01:16.240 3D cursor and bounding box sent up. 01:16.550 --> 01:22.020 Now we will use the three objects in our scene as the example for the pivoting. 01:22.280 --> 01:29.600 Now if we go ahead and select the camera hold down Shift and select the lamp and Cube. 01:29.630 --> 01:35.990 We've now got three objects selected and we can confirm that in the hierarchy as well over in the outliner. 01:36.500 --> 01:40.230 So the first option is this median points. 01:40.250 --> 01:45.890 Now I'd say the first option that's obviously not the one at the top is the default one that usually 01:45.920 --> 01:53.000 you'll be set to and if we rotate around you'll see that the Widget the 3D manipulator widget is now 01:53.270 --> 01:59.150 placed in the middle will kind of in the middle of these three places. 01:59.150 --> 02:02.490 And that gives us a clue as to what's going to happen. 02:02.600 --> 02:11.180 That does mean if we were to scale or rotate it would scale around or towards that point unescaped come 02:11.180 --> 02:11.720 out. 02:11.720 --> 02:15.050 It may even rotate around that point. 02:15.110 --> 02:16.290 Pretty cool. 02:16.400 --> 02:20.390 Pretty useful as well if that's what you want to be able to do. 02:20.540 --> 02:22.670 Now let's go to the active element. 02:22.670 --> 02:23.680 What does that mean. 02:23.840 --> 02:29.510 Well you will notice at this point that now these 3D manipulator which has actually gone all the way 02:29.510 --> 02:35.880 to the cube if you can't see this 3-d manipulator widget you may want to turn it on in the toolbar. 02:35.900 --> 02:39.370 You may have clicked that by accident and turned it off. 02:39.380 --> 02:45.800 Now with this you probably guessed already is going to rotate around the cube itself around the cubes 02:45.890 --> 02:46.850 centre. 02:47.150 --> 02:50.350 And that's all we all the way round. 02:50.360 --> 02:51.820 Lots of fun to be had. 02:52.520 --> 02:59.270 Individual origins can be incredibly useful when you're scaling things by their self or rotating them. 02:59.270 --> 03:04.970 So if we rotate here you'll see that both the camera and the cube are rotating the lamp is as well we 03:04.970 --> 03:06.540 just can't see it. 03:06.570 --> 03:11.340 And again scaling will scale around their own origins. 03:11.340 --> 03:12.720 Now what's the origin. 03:12.730 --> 03:17.330 Here's that little orange or yellow dots in the middle of every object. 03:17.370 --> 03:21.370 Now we'll cover that in much more detail later on. 03:21.860 --> 03:26.900 Finally the 3D cursor and the reason why I say finally is because we're not really going to go into 03:26.900 --> 03:28.040 the bounding box. 03:28.050 --> 03:30.020 I'll show you all it does in a second anyway. 03:30.410 --> 03:36.470 The 3-d cursor is the crosshairs that you move about all the time and we can see that because the 3D 03:36.470 --> 03:42.560 cursor has been set as the pivot point the 3D manipulator which is also moving accordingly. 03:42.590 --> 03:47.110 And now we would rotate and scale around that point. 03:47.390 --> 03:53.150 So it's incredibly useful for certain tasks but incredibly frustrating when you trying to do something 03:53.150 --> 03:56.830 and don't realize why blender is behaving oddly. 03:56.840 --> 04:00.460 Now there are keyboard shortcut keys for all of this. 04:00.560 --> 04:05.050 But before we do that I'm going to do the bounding box now have a look at the bounding box. 04:05.770 --> 04:10.070 And now have a look at the medium points. 04:11.560 --> 04:17.050 Now the bounding box is simply a box drawn around all of these objects. 04:17.320 --> 04:22.840 And then the centre of that box is displayed and that's slightly different because of the shape of the 04:22.840 --> 04:25.800 box then the medium point will be. 04:26.710 --> 04:34.510 So there we go that takes into account the extra dimension on the cube here that goes out this way. 04:34.510 --> 04:41.730 The medium point just takes the actual points that these origins exist in 3-d space. 04:42.760 --> 04:44.890 So let's talk about shortcut keys. 04:44.890 --> 04:46.990 So let's start with the 3-d cursor. 04:46.990 --> 04:49.240 Because it's the simple one to get to. 04:49.400 --> 04:51.700 That's the full stop or period key. 04:51.850 --> 04:58.780 And we will see that the pivot point changes and that is one that gets people typing in values like 04:58.780 --> 05:05.020 scale by two point three or something along those lines they don't quite have it all engaged properly. 05:05.020 --> 05:12.790 It's very easy to hit the full stop or indeed any key on the keyboard since Blender's so keyboard heavy 05:13.240 --> 05:16.520 and change the setting you didn't realize you could change. 05:16.730 --> 05:22.550 Now colmar which is right next to the period full stop will change it to bounding box. 05:23.550 --> 05:26.850 And then we need modifier keys for the next one. 05:26.850 --> 05:34.980 So in order to do individual origin's we need to hold down control and full stop of all the period key 05:35.910 --> 05:43.420 and then median is control and the karma and that sets us back to our default position. 05:43.530 --> 05:48.080 And finally active element is altes and full stop. 05:48.210 --> 05:53.830 And of course those that are on a system where the old key is a system key. 05:53.850 --> 06:00.430 You may need to hold down the windows key at the same time that's particularly useful for Linux users. 06:00.630 --> 06:06.540 So pivot points are incredibly useful and if you find Blender's being a bit weird when you're scaling 06:06.540 --> 06:08.830 it's not doing what you think it should be doing. 06:08.880 --> 06:10.350 Then do check your pivot point. 06:10.350 --> 06:16.400 You may have changed it inadvertently or changed it and forgotten that you changed it. 06:16.440 --> 06:22.820 The common ones to change them to are the 3D cursor individual origins and medium point. 06:22.920 --> 06:28.220 I very rarely use active elliman or bounding box centre in my work. 06:31.370 --> 06:33.380 And of course you know what time it is now. 06:33.710 --> 06:35.490 It's time for a challenge. 06:36.380 --> 06:39.840 I would like you to go ahead and scale a cube. 06:40.070 --> 06:42.220 But in a particular way. 06:42.380 --> 06:50.600 So you start from the default scene scale a cube from its base but without moving it. 06:51.260 --> 06:55.190 And there will be several ways of achieving this. 06:55.580 --> 07:02.360 She is scanning the cube from its base so essentially is base does not move from where it starts but 07:02.360 --> 07:05.910 the rest of it will grow outwards from that base. 07:06.670 --> 07:07.660 Pulls a video. 07:07.660 --> 07:08.400 Think about it. 07:08.410 --> 07:10.540 There are several ways of achieving this. 07:10.690 --> 07:15.560 Neither are better than the alpha balls video now and give that a go. 07:18.170 --> 07:19.570 Okay guys welcome back. 07:19.700 --> 07:24.330 Let's go ahead and scale a cube from its base without moving it. 07:25.590 --> 07:31.510 Okay so we're back into the default blender scene here and there are a couple of options. 07:31.560 --> 07:38.250 One does involve kind of moving it so I'm going to rule that one out because you can move the origin 07:38.250 --> 07:45.300 itself to the base and then just use the median tool or individual origins or active element and then 07:45.300 --> 07:46.480 scale up from there. 07:46.590 --> 07:54.220 But what we can do is we can actually put three the cursor on the base and I can approximate that by 07:54.810 --> 07:57.890 moving around and clicking on the base. 07:58.050 --> 08:02.490 And now it will scale outwards from the base itself. 08:02.530 --> 08:06.540 If I have it in 3D cursor pivot point. 08:06.540 --> 08:11.970 Now let's scale that and we can see the base is not getting any higher. 08:12.090 --> 08:14.580 Now this is quite difficult to see from this angle. 08:14.580 --> 08:20.700 So I'm going to go into orthographic projection mode and from the side and we should see here that is 08:20.700 --> 08:24.720 one bloody unit negative on the z and one blender unit higher. 08:24.850 --> 08:28.680 And if we scale up we notice that it doesn't get any lower. 08:28.710 --> 08:32.130 It is literally scaling around that 3-d cursor. 08:32.150 --> 08:34.950 Of course everything else is as well including the camera. 08:34.950 --> 08:39.370 So I'm just going to select the cube by itself and make it larger. 08:39.750 --> 08:42.330 And there we go we scaled it up from the base. 08:42.480 --> 08:43.290 Excellent. 08:43.290 --> 08:47.120 How did you guys get on please share your work in the forum. 08:47.220 --> 08:49.780 And I will see you guys in the next lecture.
