WEBVTT 1 00:00:00.000 --> 00:00:04.000 Welcome to Moving, Rotating, and Resizing! 2 00:00:04.000 --> 00:00:08.000 In this video we're going to show you how to control your model with more 3 00:00:08.000 --> 00:00:12.000 precision. We'll go over Blender's coordinate system. 4 00:00:12.000 --> 00:00:16.000 And just a reminder for those who know and for those new- 5 00:00:16.000 --> 00:00:20.000 comers to the 3D world, coordinates are always listed in the 6 00:00:20.000 --> 00:00:24.000 order (X, Y, Z). 7 00:00:24.000 --> 00:00:28.000 Always in that order, so if you ever see a series of numbers with commas in between them 8 00:00:28.000 --> 00:00:32.000 like that, we're talking about the X coordinate, the 9 00:00:32.000 --> 00:00:36.000 Y coordinate, and the Z coordinate. Let's hop over 10 00:00:36.000 --> 00:00:38.000 into Blender. 11 00:00:38.000 --> 00:00:41.033 So here we are in Blender with our wedge 12 00:00:41.633 --> 00:00:44.533 and I'm now in Object Mode as well. 13 00:00:44.533 --> 00:00:46.800 The first thing I'd just like to do is draw your 14 00:00:46.800 --> 00:00:50.800 attention to our 3D Manipulator Widget, with 15 00:00:50.800 --> 00:00:54.800 it's orange blob in the middle. Now that orange blob is 16 00:00:54.800 --> 00:00:58.800 called the Origin. Now, at some point, during the construction 17 00:00:58.800 --> 00:01:02.800 of my wedge the Origin has ended up outside of our model, 18 00:01:02.800 --> 00:01:06.800 and that, in this case, I don't want that to happen. 19 00:01:06.800 --> 00:01:10.800 So I want you to go over to your Tool Shelf, if that has happened to you, 20 00:01:10.800 --> 00:01:14.800 where it says Set Origin under the Tools Options 21 00:01:14.800 --> 00:01:18.800 I'd like you to change that and set the Geometry 22 00:01:18.800 --> 00:01:22.800 to the Origin or the Origin to Geometry. One move is the object, one 23 00:01:22.800 --> 00:01:26.800 move is the Origin, but essentially you'll end 24 00:01:26.800 --> 00:01:30.800 up with your Origin back in the middle. Right, 25 00:01:30.800 --> 00:01:34.800 so I'd like you to put away your Tool Shelf, for the moment, 26 00:01:34.800 --> 00:01:38.800 and bring open your Properties. 27 00:01:38.800 --> 00:01:42.800 Now, I'm just going to scroll up here, so we can see our Transform options. 28 00:01:42.800 --> 00:01:46.800 Incidentally, if you're not seeing that you may 29 00:01:46.800 --> 00:01:50.800 still be in Edit Mode. If you're in Edit Mode, it 30 00:01:50.800 --> 00:01:54.800 gives you a different set of options. In this case, you want to be 31 00:01:54.800 --> 00:01:58.800 in Object Mode. So we've got Location, 32 00:01:58.800 --> 00:02:02.800 Rotation, and Scale. Ideal, that's exactly what we want to play with! 33 00:02:02.800 --> 00:02:06.800 Now the location is the location of that little orange blob there, 34 00:02:06.800 --> 00:02:10.800 so if we set it to 0, 0, and 0, 35 00:02:10.800 --> 00:02:14.800 surprise surprise the wedge itself or 36 00:02:14.800 --> 00:02:18.800 the orange blob, the bang of the middle, sits where X, Y, and 37 00:02:18.800 --> 00:02:22.800 Z all equal 0. And you can tell which way it 38 00:02:22.800 --> 00:02:26.800 is positive and which way is negative, simply by the direction of 39 00:02:26.800 --> 00:02:30.800 that arrow. So if for some reason you had your model upside- 40 00:02:30.800 --> 00:02:34.800 down, like this, you could still see which way was positive and which 41 00:02:34.800 --> 00:02:38.800 way was negative. I'm just going to flip the model back over. Wow, 42 00:02:38.800 --> 00:02:42.800 not feeling too dizzy there! So with this we can control 43 00:02:42.800 --> 00:02:46.800 our model precisely, so we can say I want the Origin 44 00:02:46.800 --> 00:02:50.800 to be at X is 1. And we can see it's moved it along by 1, 45 00:02:50.800 --> 00:02:54.800 and Y equals 4 and it will shift it towards us 46 00:02:54.800 --> 00:02:58.800 that way by 4. Now the Rotation 47 00:02:58.800 --> 00:03:02.800 is very similar, we've got X, Y, and Z rotation. 48 00:03:02.800 --> 00:03:06.800 The Z rotation would be, if you imagine, a skewer 49 00:03:06.800 --> 00:03:10.800 going through our object where that blue arrow is. If 50 00:03:10.800 --> 00:03:14.800 we play with the Z, you can see it spins around 51 00:03:14.800 --> 00:03:18.800 as if someone had literally poked a skewer through the Z axis. 52 00:03:18.800 --> 00:03:22.800 Now finally, we've got our Scaling options 53 00:03:22.800 --> 00:03:26.800 here, so we can scale things individually. Now 54 00:03:26.800 --> 00:03:30.800 the great thing about this is, it scales the actual model itself. 55 00:03:30.800 --> 00:03:34.800 So it's not relative to these X, Y, and 56 00:03:34.800 --> 00:03:38.800 Z's anymore, so it remembers how we created 57 00:03:38.800 --> 00:03:42.800 the model in the first place. So if we scale it on the X axis, 58 00:03:42.800 --> 00:03:46.800 it will actually get narrower and wider. 59 00:03:46.800 --> 00:03:50.800 If we scale it on Z, it will get taller and narrower, 60 00:03:50.800 --> 00:03:54.800 and of course, we can actually input the values 61 00:03:54.800 --> 00:03:58.800 we want in here, so it's precise. And if you need to set it to a 62 00:03:58.800 --> 00:04:02.800 certain dimension, you can do so. Here we can say X 63 00:04:02.800 --> 00:04:06.800 equals to 1, so that would make the width of that, 64 00:04:06.800 --> 00:04:10.800 in this case, 1 Blender unit. I could set the Y, 65 00:04:10.800 --> 00:04:14.800 that is the length, to 4. So now that is a 1 in 4 66 00:04:14.800 --> 00:04:18.800 wedge, and finally the Z, I could set that to 1 again 67 00:04:18.800 --> 00:04:22.800 and we end up with a much more sensible sized wedge. 68 00:04:22.800 --> 00:04:26.800 Now that is still a pretty big wedge being a meter tall but there we go, 69 00:04:26.800 --> 00:04:30.800 and that changes the scale 70 00:04:30.800 --> 00:04:34.800 accordingly. So if we change this to 71 00:04:34.800 --> 00:04:38.800 2, we'll see that the scale as also changed from our original 72 00:04:38.800 --> 00:04:42.800 model, but the dimensions have allowed us to make the wedge 73 00:04:42.800 --> 00:04:46.800 in exact scale on the X, Y, and Z 74 00:04:46.800 --> 00:04:50.800 axes. I feel a challenge coming on! 75 00:04:50.866 --> 00:04:54.866 What I'd like you to do is grab your wedge and 76 00:04:54.866 --> 00:04:58.866 move it to an exact location. So I'd like you to rotate 77 00:04:58.866 --> 00:05:02.866 the wedge, so the pointy end is facing up. Make 78 00:05:02.866 --> 00:05:06.866 it half the size it was before, and make sure the Origin 79 00:05:06.866 --> 00:05:10.866 is placed at (0, 4, 80 00:05:10.866 --> 00:05:14.866 2). So pause the video now and go try 81 00:05:14.866 --> 00:05:18.866 doing that! OK 82 00:05:18.866 --> 00:05:22.866 welcome back! Let's hop straight back over to Blender and do our 83 00:05:22.866 --> 00:05:24.133 challenge! 84 00:05:25.133 --> 00:05:28.200 I will want, if I imagine a 85 00:05:28.200 --> 00:05:32.200 skewer going through my model... In fact, I'm going to just 86 00:05:32.200 --> 00:05:36.200 set it so that the Rotation is 0 on Z as well, so we 87 00:05:36.200 --> 00:05:40.200 can imagine things a bit better. So I want to move that so the pointy end is facing 88 00:05:40.200 --> 00:05:44.200 up. So I'm imagining a skewer going through it, it would go through 89 00:05:44.200 --> 00:05:48.200 the X axis. So I need to go to X and I want to 90 00:05:48.200 --> 00:05:52.200 rotate it 90 degrees, and there we go, our 91 00:05:52.200 --> 00:05:56.200 pointy end is facing up. Now we wanted the 92 00:05:56.200 --> 00:06:00.200 location to be (0, 4, 2). So here 93 00:06:00.200 --> 00:06:04.200 we can go 0. We've already got it set to 4, fortunately, 94 00:06:04.200 --> 00:06:08.200 and here we can have it set to 2. 95 00:06:08.200 --> 00:06:12.200 There we go, it's set at the right location! And finally the Scale! 96 00:06:12.200 --> 00:06:16.200 So back to our original Scale, this would be 97 00:06:16.200 --> 00:06:20.200 0.5 to make it half the size, 0.5 here, and 98 00:06:20.200 --> 00:06:24.200 again 0.5 there. So now our wedge is 99 00:06:24.200 --> 00:06:28.200 set at the right coordinates. Let's just check! (0, 100 00:06:28.200 --> 00:06:32.200 4, 2). Yep, it's half the size it was before in 101 00:06:32.200 --> 00:06:36.200 all dimensions, yep! And finally, 102 00:06:36.200 --> 00:06:40.200 Rotating the wedge so the pointy end is facing up! 103 00:06:40.200 --> 00:06:44.200 There we go excellent! So that's exactly positioned where 104 00:06:44.200 --> 00:06:48.200 we wanted it! How did you guys get on? I'd like you to post your 105 00:06:48.200 --> 00:06:52.200 results in the discussion against this lecture, and I'll see you in 106 00:06:52.200 --> 00:06:55.266 the next one! Take care!
