WEBVTT 00:00.330 --> 00:03.980 Welcome to a 3-d cursor and origins. 00:03.990 --> 00:08.850 So in this video we're going to take another look at our reference pieces and we're going to look for 00:08.850 --> 00:12.400 some commonality to save us time with our modelling. 00:12.660 --> 00:20.520 And finally we're going to use the 3-d cursor and the origin associated with an object to accurately 00:20.520 --> 00:22.200 control our piece. 00:22.530 --> 00:28.050 So let's go back to our chosen dimensions that we have a look at earlier and we've already done our 00:28.050 --> 00:29.850 porn and it's three centimetres. 00:29.850 --> 00:33.150 The base is a three blender use in this case. 00:33.150 --> 00:39.460 Now all of the other pieces bava King have a four centimetre base and that's what we've picked. 00:39.480 --> 00:42.890 And that is a third larger again to 33 percent larger. 00:42.890 --> 00:49.350 So when we go and scale in a bit we'll need to scale by one point three three three three etc.. 00:49.410 --> 00:51.610 I'm not quite sure how many 3s we have need. 00:51.750 --> 00:54.900 We can have a look anyway and see as we go. 00:54.960 --> 00:59.680 So let's start modelling our bishop now and hop on over into a blender. 01:00.090 --> 01:04.980 Okay so I've gone ahead and I've opened up my low poly pawn because that's what we're going to be basing 01:05.250 --> 01:09.330 the next few lectures on as we go ahead and create our bishop. 01:09.360 --> 01:15.270 Now the first thing we're going to need to do here is scale our object now by default. 01:15.270 --> 01:20.910 It will scale around the origin which can cause a couple of issues especially since we want the bishop 01:20.910 --> 01:24.000 itself and indeed the porn as it is at the moment. 01:24.000 --> 01:29.670 We wanted to stay flush with the ground and we can see here if we just scaley forces it underwears Z 01:29.730 --> 01:31.400 equals zero. 01:31.440 --> 01:33.560 There are a couple of ways we can go around that. 01:33.690 --> 01:38.340 So I want to explore moving the origin because that's what is going around at the moment understanding 01:38.340 --> 01:43.740 what the origin is used for and just in case you end up ruining something else later on. 01:43.740 --> 01:50.370 And also some other options when it comes to moving our model including the 3D cursor because we can 01:50.370 --> 01:56.530 use that as what's called a pivot point at the moment our pivot point is set to the origin. 01:56.680 --> 02:01.800 And that's something we can control on the 3G head bar next object mode edit mode before our shading 02:01.800 --> 02:02.900 setting for the viewport. 02:02.900 --> 02:08.760 And next to that we've got pivot points and you can set the active element which in this case would 02:08.760 --> 02:14.100 be the same as what we've got on the screen because we've only got one object selected if you've got 02:14.100 --> 02:15.840 multiple objects selected. 02:15.840 --> 02:21.000 It means that we show everyone is the active one of the light orange border around will be the one then 02:21.000 --> 02:24.480 it scales around rotates around et cetera et cetera. 02:24.690 --> 02:30.090 The medium point is an average point between everything the individual origins will if you've got more 02:30.090 --> 02:35.140 than one object selected it was scaled them around their own origins and nothing else. 02:35.250 --> 02:37.020 Their 3-d cursor. 02:37.020 --> 02:42.090 Now that's a very useful one and we'll explore that in a few moments and then we've got a bounding box 02:42.090 --> 02:42.460 Centre. 02:42.460 --> 02:46.830 Now this is a weird one it often is very similar to the medium point. 02:46.830 --> 02:52.410 But if you imagine put in all of your objects in a box where their extremities touch the corners of 02:52.410 --> 02:58.650 those boxes that L. That box Sorry that is the bounding box itself and there are reasons why you'd want 02:58.650 --> 02:59.100 to use that. 02:59.100 --> 03:04.590 I have very rarely use that I often use individual oranges 3D cursor a medium point. 03:04.710 --> 03:09.110 And again I very rarely use the active elements as those three in the middle that we tend to pick. 03:09.180 --> 03:15.570 So straightaway here we can do the 3-d cursor and it looks like the 3D cursors roughly on the base. 03:15.630 --> 03:21.720 Well is it let's make sure that is the case that scroll down on the end panel you mainly depress the 03:21.720 --> 03:24.960 letter N on your keyboard to bring that up the properties panel. 03:24.960 --> 03:29.210 We scroll down we can see the literal 3D cursors position in the world. 03:29.250 --> 03:30.830 0 0 0. 03:30.900 --> 03:32.300 Now that is brilliant. 03:32.310 --> 03:38.550 That means that we can now scale with it around the 3D cursor and you can see it stays on the base and 03:38.550 --> 03:40.450 that is incredibly important. 03:40.580 --> 03:44.600 And apart from when you go upside down so that is the first step here. 03:44.610 --> 03:48.700 Now it does look like I'm slightly not looking at it from an angle or. 03:48.720 --> 03:49.890 Even better than that. 03:50.010 --> 03:54.540 It looks like our piece itself isn't actually on zet where Z equals zero. 03:54.540 --> 03:59.530 So we're going to have to do a bit of manipulation here to get it into the right place. 03:59.550 --> 04:00.840 So how do we do that. 04:00.840 --> 04:06.900 What do we do in order to move something to a very exact position where it can be complicated or it 04:06.900 --> 04:11.610 can be easy it depends how you want to approach it and on how complicated your model is. 04:11.610 --> 04:16.350 Obviously the best thing would be not to put yourself into this position in the first place but hey 04:16.530 --> 04:18.660 it's happened here obviously. 04:18.720 --> 04:23.510 So the first thing we can do is note that wherever you click the you left click. 04:23.640 --> 04:28.180 And the three cursor gets placed it will snap to that particular face. 04:28.240 --> 04:34.300 So I will look at that that snaps to that face that snaps that face and it snapped to this face or you 04:34.300 --> 04:39.480 can see that the Z position of the 3D curses North Point North 5 5 2 0. 04:39.480 --> 04:43.200 So it is indeed not where Z equals zero. 04:43.740 --> 04:49.030 So we could subtract that number now from the position in the world that this object is. 04:49.050 --> 04:54.870 That's one possible thing but that's a bit clunky I'd rather be much more precise about that. 04:54.870 --> 04:59.960 So in order to position this in the world what I first do is make sure that I've got the three. 05:00.270 --> 05:07.380 In an ideal position and I want the origin at this point at this particular case I want my origin to 05:07.380 --> 05:11.310 be at the base of the object in the centre of the base of the object. 05:11.340 --> 05:15.540 So I'm going to need to make sure I've got that face selected on the bottom so I'm going to have to 05:15.540 --> 05:20.460 go into edit mode go to face select and select that face. 05:20.460 --> 05:27.870 Now that I've done that I can move the 3D cursor to that face and if I go shift and s we end up with 05:27.870 --> 05:32.310 a snapping menu with a lot of options one of them is cursor to selected. 05:32.310 --> 05:39.660 Now what this is actually doing is it's placing the cursor the 3D cursor to the centre of whatever is 05:39.660 --> 05:40.530 selected. 05:40.540 --> 05:46.020 Now if we've got a face selected of course it's going to place it smack bang in the middle of the face. 05:46.120 --> 05:50.790 If we've got an edge selected it's going to place it smack bang in the middle of that edge so we go 05:50.790 --> 05:55.820 ahead select this edge here and go shift an S cursor to selected who sits in the middle. 05:55.890 --> 06:03.660 And if we have verte a vertex selected we can also shift an S and add the cursor selected there. 06:03.690 --> 06:05.210 So we've got lots of control. 06:05.220 --> 06:10.320 Now of course I'm not going to spend too much time playing with this but now you can see it scales in 06:10.320 --> 06:12.590 and out from that cursor. 06:12.660 --> 06:15.050 If we wanted to I'm going to press escapin come out. 06:15.080 --> 06:18.890 That's what I really want is it to be in the centre of all of these. 06:18.940 --> 06:21.640 See something to select the edge loop running around. 06:21.670 --> 06:26.670 You could select the face but selecting all of the edges or vertices that make up a face is the same 06:26.670 --> 06:28.110 as selecting that face. 06:28.110 --> 06:31.350 I'm going to go shift an S cursor to selected. 06:31.710 --> 06:32.060 Okay. 06:32.120 --> 06:34.010 We'll come back out into object mode. 06:34.140 --> 06:39.370 Once I'm in object mode I can come round and set the origin in the tool shelf. 06:39.450 --> 06:43.570 If you haven't got that open you need to open up that up under the Tools tab. 06:43.590 --> 06:46.440 If we go down set origin in here we go. 06:46.560 --> 06:48.540 We have origins a 3-d cursor. 06:48.570 --> 06:55.710 Now if you want the gymnastics with your fingers you can you shift control oltz and see which is quite 06:55.710 --> 06:57.870 a handful and a mouth full. 06:57.870 --> 07:03.030 So I often just use this menu on the side and it's obviously very apparent what I'm doing if I am going 07:03.030 --> 07:04.080 through a menu. 07:04.260 --> 07:09.090 And once we click on that we see that the objects origin itself has gone to that value. 07:09.150 --> 07:13.730 The object is now at Z equals zero point zero five five two three. 07:13.740 --> 07:19.260 So what I'm going to do theirs I'm going to go to that location information in me of the transform this 07:19.290 --> 07:24.250 object and type in zero there so then I know it's exactly on the base. 07:24.270 --> 07:30.990 Now one of the things to bear in mind is that the origin is used for many other things in blender including 07:31.290 --> 07:33.960 the centre of mass when it comes to physics. 07:33.960 --> 07:39.090 So if you were to apply physics to this chess piece just like we did at the end of the bowling section 07:39.410 --> 07:43.980 if you apply it to this chess piece it won't behave as you would expect it to because the centre of 07:43.980 --> 07:49.860 mass of this object is not at the bottom of this object that would be impossible it be somewhere in 07:49.860 --> 07:50.870 the middle. 07:50.940 --> 07:55.890 And this is where you can come back after you've moved it to an appropriate location so we've matched 07:55.950 --> 07:57.630 up where Z equals zero. 07:57.660 --> 08:03.780 We can go back to set origin and now set it to the centre of mass or even just to the geometry it's 08:03.780 --> 08:07.040 going to be good enough for what we are intending to do. 08:07.050 --> 08:07.540 And there we go. 08:07.540 --> 08:12.110 The objects origin is back up the top there but it's all laid out. 08:12.120 --> 08:18.420 And now we know that we can scale it according to the 3-d cursor rather than relying on the origin all 08:18.420 --> 08:19.050 the time. 08:19.080 --> 08:23.490 We've now got much better control it's in the right position we can scale it up from the base if I go 08:23.490 --> 08:27.030 back round the side more the front view in this case. 08:27.030 --> 08:29.850 We noticed that when I go and scale it around the thrilly cursor. 08:29.850 --> 08:34.830 Bear in mind the three cursor is not zero at the moment so that's make sure it is at zero. 08:34.830 --> 08:35.620 There we go. 08:35.640 --> 08:36.740 I can now scale it. 08:36.750 --> 08:43.650 And the base itself will stay where Z equals zero and that's very important because we don't want to 08:43.650 --> 08:46.840 have to keep editing our object because of that. 08:47.070 --> 08:47.830 Okay. 08:47.970 --> 08:51.740 So with all of that it's time for a challenge. 08:52.770 --> 08:54.140 Okay see your challenge. 08:54.150 --> 08:57.260 Well it's going to be to create the bishop base itself. 08:57.270 --> 09:02.790 And of course we're going to be doing this over a couple of lectures time just to solidify some new 09:02.790 --> 09:04.270 tools in our mind. 09:04.410 --> 09:08.420 So scale the bishop's base to four blender units in diameter. 09:08.430 --> 09:14.320 Now this is going to be I think a 33 percent increase so you might have to just scale by one point three 09:14.320 --> 09:21.240 three three that might do it or you could do it any other way that you choose remember to set the base 09:21.240 --> 09:23.430 of Archbishop to Z equals zero. 09:23.430 --> 09:29.630 Otherwise we'll go to go ahead and have a floating piece and this is not levitating chess. 09:29.690 --> 09:35.040 Now I would like you to use reference material to make sure the neck of our porn as it comes into a 09:35.040 --> 09:37.050 bishop is the right height. 09:37.050 --> 09:41.790 However I do not want you to delete any of your geometry just yet. 09:41.790 --> 09:47.430 Now it may be tempting to remove the ball from the top of our bit of our bishop which is currently a 09:47.430 --> 09:47.880 pawn. 09:48.000 --> 09:53.130 But we'll go through that in a later lecture because there's a couple of things I want to teach to you 09:53.230 --> 09:56.690 that if you go ahead and delete it you won't be able to follow along. 09:56.850 --> 10:02.490 And remember I do love seeing your works remember to save it and then share it with us. 10:02.520 --> 10:03.970 Looking forward to seeing it. 10:03.990 --> 10:06.220 Pause a video now and give that a go. 10:08.180 --> 10:09.460 OK everybody welcome back. 10:09.590 --> 10:12.710 Let's go ahead now and create our bishop base. 10:13.910 --> 10:20.480 Okay so the first thing I've spotted here is that my low poly porn itself is in the archive and on the 10:20.480 --> 10:23.140 side here it's still called chest piece base. 10:23.150 --> 10:29.120 I'm going to call it low poly porn and I'm going to make sure my file is safe before I start modifying 10:29.120 --> 10:30.880 it and changing it into a bishop. 10:31.000 --> 10:35.520 And I want to save as a low poly bishop. 10:35.540 --> 10:40.610 Now what I am going to do later on is just shift those things outside of the archive folder. 10:40.610 --> 10:42.890 That's just moving things in a hierarchy. 10:42.980 --> 10:49.280 But I do want you to be aware that if I go ahead and do that or you do that in future when you go to 10:49.310 --> 10:54.810 open recent these items here if it cannot be found that is you've moved it or even deleted it. 10:54.830 --> 10:57.820 It'll just remove it from here and give you an error message. 10:57.980 --> 11:04.700 Okay so we've got low poly Bishop ready to go but we don't have our our actual image on the side so 11:04.700 --> 11:09.290 let's make sure that's loaded up so I have come back here and are. 11:09.310 --> 11:11.240 It means that we've got is a pawn. 11:11.240 --> 11:16.450 Let's go ahead and load in the appropriate image section assets. 11:16.460 --> 11:20.580 There is the bishop and that will give us an idea of what's going on now. 11:20.600 --> 11:25.640 The image is at the wrong point here but it's also not wide enough so I'm going to have to change the 11:25.670 --> 11:28.130 image around to fit a size. 11:28.130 --> 11:32.350 Now is actually fitting this quite well at the moment. 11:32.810 --> 11:38.350 And I might just bring the image down ever so slightly so we need to move its vertical location. 11:38.480 --> 11:44.030 And if you're moving it around and it's just moving a bit too much you can hold down the SHIFT key in 11:44.030 --> 11:46.720 any of these fields and move it much slower. 11:46.730 --> 11:49.890 And if there are a down to about there I'm quite happy with that. 11:49.970 --> 11:56.390 Now the next thing for me to do is scale up this image so it's the right size for Blender units across 11:56.390 --> 12:01.330 which is two on this side so that's from one side over here to about here. 12:01.350 --> 12:02.840 Now I'd probably go. 12:02.900 --> 12:04.310 There we go. 12:04.490 --> 12:07.370 It's already a size of three if we make it a size for perfect. 12:07.520 --> 12:13.260 So we are going to have to manipulate that again and the height again sorry and there we go. 12:13.280 --> 12:16.570 So we've now got a good base to work on. 12:16.670 --> 12:20.270 Now the first thing I'm going to do is literally scale up my model. 12:20.270 --> 12:23.410 I'm going to make sure the 3D cursor is in the centre of my scene. 12:23.570 --> 12:25.250 I can do that in a couple of ways. 12:25.250 --> 12:29.510 I can go shift and see and that will centre everything but it also changed my view. 12:29.510 --> 12:34.430 I don't want it doing that so I'm going to go shift an S and cursor to centre it's going to put it where 12:34.700 --> 12:36.930 X Y and Z for the 3D cursor. 12:36.940 --> 12:43.220 Equal 0 0 0 and I could have highlighted all of these fields and typed in zero as well. 12:43.220 --> 12:45.820 Lots of different options with doing the same thing you're getting the hang of this. 12:45.820 --> 12:48.630 Now I know that there's always more than one way to do something. 12:48.760 --> 12:50.750 Now the next thing is my bishop. 12:50.750 --> 12:55.870 I've just glanced over at the outline on the right hand side it's called low poly pawn. 12:55.880 --> 13:01.340 It now has to be called low poly bishop and I'm going to get into the habit of saving my work quite 13:01.340 --> 13:02.150 regularly. 13:02.190 --> 13:07.340 Glenda can be a bit funny when it comes to crashing and certainly if you're hopping in and out of rendered 13:07.340 --> 13:09.440 mode lots that can happen. 13:09.590 --> 13:14.750 Now the scaling itself we can see see at the pivot point down here it's set to the 3D cursor. 13:14.750 --> 13:16.270 That's brilliant that's what we want. 13:16.460 --> 13:21.950 The next thing is to just scale this up by a factor of one point thirty three and what we can do is 13:21.950 --> 13:28.400 have a look at the dimensions on the properties panel the end panel and make sure that the x and y values 13:28.460 --> 13:32.390 are 4 and then we can stretch it up in the z axis later run. 13:32.450 --> 13:34.040 So let's go ahead and scale. 13:34.370 --> 13:38.890 And here we're going to scale by one point three. 13:38.930 --> 13:43.790 So one point three has taken its to three point nine one point three three is taken it's three point 13:43.790 --> 13:47.300 ninety nine three point nine nine nine if we type in one or three there we go. 13:47.300 --> 13:51.880 So one point three three three three has a dimension of four. 13:51.950 --> 13:56.240 So that's a great start and we can see here that's Ares I meant our height. 13:56.270 --> 13:58.510 Dimension isn't quite on it at the moment. 13:58.520 --> 14:03.320 I'm going to have to probably later on add in a loop here to make it a bit slender in the middle so 14:03.320 --> 14:03.970 it comes up. 14:04.100 --> 14:08.090 But now I can literally I'm going to hold down Shift so it doesn't move too quickly but I'm going to 14:08.090 --> 14:12.450 alter the dimensions just here and just can scale it up. 14:12.560 --> 14:16.010 Now it's scaling around the origin so I've got to be careful. 14:16.020 --> 14:19.990 They're just altering the dimensions won't work so I'm going to undo that. 14:20.150 --> 14:26.990 And now just scale again but this time lock it to the z axis and then I can lift it to approximately 14:26.990 --> 14:32.190 the right location so the neck the base of the neck is in the right location. 14:32.210 --> 14:32.840 Excellent. 14:32.840 --> 14:33.410 There we go. 14:33.410 --> 14:35.310 So we've got that ready to go. 14:35.330 --> 14:41.060 And of course looking at this I think we might be able to modify what's here to create the rest of the 14:41.060 --> 14:44.060 geometry but we may just go about it a different way. 14:44.060 --> 14:45.490 I haven't decided yet. 14:45.620 --> 14:46.270 But there we go. 14:46.270 --> 14:49.790 That's all ready to go under to make sure my work has been saved. 14:49.790 --> 14:50.490 There we go. 14:50.630 --> 14:52.540 And now it's ready to share. 14:52.550 --> 14:53.350 Excellent. 14:53.360 --> 14:55.300 How did you guys get on remember. 14:55.430 --> 15:00.040 Pleased to show your work over in the discussions and I'll see you all in the next lecture.
