WEBVTT 00:00.820 --> 00:01.600 Hi guys. 00:01.600 --> 00:03.490 Welcome to building blocks. 00:03.490 --> 00:08.590 And we're going to be talking about simple shapes initially and this is going to be work in a crack 00:08.590 --> 00:11.320 open blender has start making some stuff as well. 00:11.410 --> 00:13.980 So simple shapes that go together well. 00:13.990 --> 00:20.220 Well they're all basically triangles right angle triangle as a square splits in two. 00:20.350 --> 00:27.460 And that can also make a hexagon which is three general shapes basic geometric shapes that tests late 00:27.970 --> 00:29.590 all the time perfectly. 00:29.950 --> 00:36.010 So a right to hang this is just an example of size of course a right Hagel triangle whose sides are 00:36.010 --> 00:40.020 one and one and the square root of two on the long side. 00:40.030 --> 00:46.570 There we would go together perfectly with a square that's one by one and of course any other integer 00:46.570 --> 00:53.980 rectangles that are one by one by two one by three whatever those will all go together well obviously 00:53.980 --> 00:59.170 we don't want to smaller building blocks and we don't want two larger building blocks because that doesn't 00:59.170 --> 01:02.660 give us much in the way of flexibility. 01:02.680 --> 01:10.600 You can have an I sausalito triangle whose base is one and the sides are two in length which is very 01:10.600 --> 01:19.710 useful for Roof components and things like that and equal lateral triangles of side length one as well. 01:19.720 --> 01:24.310 These will all fit together really well and consistently. 01:24.400 --> 01:29.130 Now those are very basic shape so what are the disadvantages. 01:29.470 --> 01:32.690 None at this stage. 01:32.740 --> 01:36.450 Later on it can feel and is restrictive. 01:37.210 --> 01:41.170 That is where you want to be customizing and adding detail. 01:41.200 --> 01:49.850 Not in the early stages we really want to be quick and effortless with our development at this stage. 01:49.930 --> 01:56.790 We'll also be seeing that you can type formulas in the fields in blender which is incredibly powerful 01:57.550 --> 02:03.590 and we can use this to solve otherwise complicated measurements in blender. 02:03.670 --> 02:08.890 So let's go make some simple shapes and hop straight on over in a blender. 02:09.280 --> 02:14.710 Okay so now we're back over in blender The first thing I'm going to do is show you the two things that 02:14.710 --> 02:15.880 I've already created. 02:15.880 --> 02:17.920 Now bear in mind I'm in my game. 02:17.950 --> 02:25.390 Asit pack folder that I've carried under assets under meshes so I have gone ahead and created a mesh 02:25.420 --> 02:29.450 object that's a square with the sizes and dimensions. 02:29.450 --> 02:32.630 Here's two by two by 2.5 in the outliner. 02:34.760 --> 02:38.150 And that matches the name of the file as well. 02:38.150 --> 02:44.290 We've got the origin at the zero and it comes out by point to five in height. 02:44.330 --> 02:46.860 Nice simple straightforward shape to make. 02:46.870 --> 02:52.550 And of course we may come back and alter that later perhaps move the origin itself to a more appropriate 02:52.550 --> 02:59.630 location if necessary or if we find we're need to import these more vertically than flat which may be 02:59.630 --> 03:00.980 an option. 03:01.040 --> 03:04.210 Then we can rotate it round and save it again. 03:04.550 --> 03:06.960 The other one is simply this cut in half. 03:06.970 --> 03:08.650 Let's go and open that now. 03:08.750 --> 03:14.810 And that's the right haggle triangle and that is exactly the same as a square just chopped in half and 03:14.810 --> 03:19.720 that will help us with any corner pieces or braces that we need to put together. 03:19.970 --> 03:20.780 Perfect. 03:20.780 --> 03:23.520 So let's go and hop over to something more exciting. 03:23.520 --> 03:25.960 I'm going to open up a brand new blender file. 03:26.940 --> 03:29.560 And let's go ahead and make the equal actual Triangle. 03:29.700 --> 03:36.600 Now this is probably the first and only time I've use Pythagoras's since I've left school. 03:36.600 --> 03:40.970 I knew there was a reason for it but no one really filled me in with the details. 03:41.070 --> 03:43.590 So I'm going to add a mesh. 03:43.590 --> 03:47.630 But this time I'm not going to add a plane or anything along these lines. 03:47.640 --> 03:49.440 I'm going to have a single vertex. 03:49.440 --> 03:54.930 Now if you can't see these options that I'm currently using that means you've not turned on something 03:55.290 --> 03:59.070 in the user preferences an add ons. 03:59.070 --> 04:00.990 Let's just have a look down here sorry. 04:01.110 --> 04:05.690 Yes is ADD meche extra objects you need to make sure that is ticked. 04:05.700 --> 04:08.740 And of course save your user settings as well. 04:08.760 --> 04:11.370 The answer add meche extra objects. 04:11.370 --> 04:13.460 Make sure there's a tick in that box. 04:14.470 --> 04:19.870 Okay so I'm going to add a single vertex which is very powerful because I don't want to end up having 04:19.870 --> 04:21.080 to delete lots of things. 04:21.100 --> 04:24.210 There's loads of ways that you can make an equal actual trial. 04:24.250 --> 04:27.740 Now I want it by two two and two so is equal actually. 04:27.760 --> 04:31.260 All angles are equal or side length a quill as well. 04:31.400 --> 04:39.460 Someone extrude this on the y axis in the positive direction by two and then it is going to line up 04:39.460 --> 04:42.100 with our other models that we've made. 04:42.100 --> 04:43.900 Now the question is here. 04:43.910 --> 04:47.180 So let's spin this round of verticals going up. 04:47.350 --> 04:53.290 So the question is here are how do I make these sides and angles right because unfortunately blender 04:53.290 --> 04:57.080 can shape the angle that you've moved a line relative to another. 04:57.220 --> 05:00.610 But it cannot give you accurate angles. 05:00.610 --> 05:05.080 You can't say I want this at 60 degrees which would be equal to a triangle. 05:05.080 --> 05:08.290 It would make it a lot easier but unfortunately you cannot do that. 05:08.440 --> 05:13.220 So what we can do is select this edge and split it in two. 05:13.630 --> 05:19.420 I won't be split it into two we're essentially making the equilateral triangle out of two right handed 05:19.420 --> 05:25.420 triangles and I am going to have to scratch my head for a few moments whilst I figure out the maths 05:25.420 --> 05:26.710 involved. 05:26.710 --> 05:34.900 This bottom one if I remember correctly the two right angled sides are labelled A and B and then the 05:34.930 --> 05:43.370 diagonal moving across is C and it's a squared plus B C squared equal C squared horray I remember. 05:43.450 --> 05:46.200 So we need to find out this one here. 05:46.210 --> 05:46.690 No we don't. 05:46.690 --> 05:47.610 That's one. 05:47.860 --> 05:49.120 So this was a Sorry this one's. 05:49.120 --> 05:50.410 Here's going to be too. 05:50.520 --> 05:52.600 So that's going to be two. 05:52.600 --> 05:59.250 This one's going to be one so one square plus some think squared equals two squared. 05:59.380 --> 06:04.610 And we can break that down we know that this is probably going to be four. 06:05.970 --> 06:10.850 This half squared is going to be all point to five. 06:10.980 --> 06:12.490 And there's an unknown here. 06:12.530 --> 06:17.940 So all we can do here is go ahead and select the virtex that we've just created by subdividing which 06:17.940 --> 06:21.950 is smack bang in the middle and extrude in the x direction by. 06:21.960 --> 06:28.740 It doesn't matter because what we can then do is either in this vector area down here in the tool shelf 06:29.070 --> 06:31.340 or indeed on the properties panel. 06:31.410 --> 06:37.500 We've got an x coordinate for the vertex itself and that means we can type in a formula here which is 06:37.500 --> 06:39.200 really really powerful. 06:39.570 --> 06:47.430 Okay so let's go ahead and whatever we're going to have here is going to be the square roots of something 06:47.790 --> 06:54.340 and the shortcut for the syntax what you need to type four square root is s q r t. 06:54.360 --> 06:59.200 Square roots and then we need to open brackets and puts whatever we're square rooting in there. 06:59.310 --> 07:03.140 So for instance if we put nine in there the answer will be three. 07:03.360 --> 07:07.620 When we click on that again it doesn't keep the formula that is important. 07:07.620 --> 07:12.450 It's not like excel where you calculate a formula and it keeps the formula in the background. 07:12.450 --> 07:17.320 It just give you the results of that so Eskew Arti open brackets. 07:17.670 --> 07:27.240 Okay so we're going to have Let's to see here there's this going to be four which is two squared which 07:27.240 --> 07:33.370 will be this long narrow edge here's a square of four minus. 07:34.080 --> 07:38.480 So in that square or four square root two which is four sorry the square of two was four. 07:38.490 --> 07:38.990 Oh dear. 07:38.990 --> 07:40.170 This is complicated. 07:40.170 --> 07:42.970 And then finally this bottom bit which is one. 07:43.290 --> 07:46.860 So for minus one was one squared is one. 07:46.920 --> 07:47.230 Okay. 07:47.240 --> 07:50.080 So that is the square root of three. 07:50.130 --> 07:52.620 So let's go ahead and do that now. 07:52.950 --> 07:54.280 One point seventy three. 07:54.330 --> 08:01.110 Now what we should find now is that when we join here and here up there we go. 08:01.110 --> 08:03.340 Fill that in and then do this one. 08:03.720 --> 08:08.700 I'm going to remove this vertex in the middle and keep it as a one solid line. 08:08.700 --> 08:13.370 Finally filling in the face and the other ones will point to five all. 08:13.380 --> 08:17.370 So it makes sense here to go point to five. 08:17.520 --> 08:20.400 And then of course we can name it appropriately has. 08:20.400 --> 08:25.820 Well now it does look like here that I've gone the wrong way so just try extruding again. 08:26.010 --> 08:26.570 Bye. 08:28.110 --> 08:32.800 Just minus point two fivers have I made my I think. 08:33.120 --> 08:33.450 Yeah. 08:33.460 --> 08:36.420 Is flip around some is going to flip the Normal's there. 08:37.660 --> 08:38.650 There we go. 08:38.650 --> 08:45.340 And now when I extrude the z axis by point to five it should go in the. 08:45.340 --> 08:47.470 Sorry z axis not x axis. 08:47.620 --> 08:48.090 There we go. 08:48.090 --> 08:49.910 It's gone up by the right amount. 08:49.930 --> 08:54.000 Now of course have I named things appropriately it's just called verte at the moment. 08:54.010 --> 08:55.690 That is no good. 08:55.690 --> 09:04.330 So this is a it's an static mesh because it's not deforming in any way and doesn't have a skeleton associated 09:04.330 --> 09:05.060 with it. 09:05.250 --> 09:08.250 Ah what do we need to call this an e q. 09:08.830 --> 09:10.690 Try and go. 09:10.870 --> 09:12.440 And it's simply too. 09:12.580 --> 09:18.550 I don't need to give any more information than that because it's going to be two by two by two. 09:18.850 --> 09:24.430 They go to boy by two by four or five and then I'm just going to highlight that all and copy that so 09:24.430 --> 09:30.490 I can actually save it and remember that we're going to save that in our directories So go ahead and 09:30.490 --> 09:30.980 have that. 09:30.980 --> 09:31.480 Yes. 09:31.510 --> 09:32.900 There we go. 09:32.920 --> 09:33.490 Excellent. 09:33.490 --> 09:36.400 So we've got there that one all laid out here. 09:36.520 --> 09:40.470 And of course it's time for you guys to have a challenge. 09:41.550 --> 09:45.480 Okay I'd like you to make some basic building blocks. 09:45.520 --> 09:53.160 So go ahead and make a nice sausages triangle with a base of two and sides of four blender units in 09:53.160 --> 09:53.800 length. 09:53.820 --> 10:01.270 You can use the technique that we've gone through or you could use any other technique that you so wish. 10:01.380 --> 10:05.390 Make sure it has a thickness of nought point to five. 10:06.430 --> 10:14.500 Now creates the plane and make it into a 3D object of point 2 5 in thickness and the right Hankel trying 10:14.500 --> 10:20.630 always you should be able to derive from the the square that you've extruded out. 10:21.770 --> 10:28.580 Make a basic ball with a doorway and window in it see a gun to take that basic plane that you've got 10:29.030 --> 10:33.770 and starts modifying it slightly to create a doorway and a window. 10:33.770 --> 10:36.440 Don't worry about anything fancy at this point. 10:36.440 --> 10:41.450 Make the doorway a simple right rectangle cut out and the same with the window as well. 10:41.450 --> 10:45.580 In fact you can make the window a smaller square in the middle. 10:45.590 --> 10:52.460 I would recommend a size at the most we've got to buy to buy a nice size and you don't have to stick 10:52.460 --> 11:02.000 to this recommendation is 3 in height by four in width by point to five in the depth itself and of course 11:02.170 --> 11:06.910 if you make in different thickness walls then you wouldn't have to use pointy 5 at all. 11:07.040 --> 11:14.840 If for the size in all of our wall sections at this particular point and remember to save each mesh 11:14.900 --> 11:19.420 individually so pause a video now and give that a go. 11:21.360 --> 11:22.110 Okay guys. 11:22.140 --> 11:23.380 Welcome back. 11:23.400 --> 11:25.970 Let's hop back over in a blender. 11:26.250 --> 11:29.290 Okay so let's go ahead and start with this. 11:29.310 --> 11:35.870 Now it is almost a isosceles triangle we just need to position these vertices in a certain place. 11:35.870 --> 11:37.720 We know it's starting from zero. 11:37.860 --> 11:44.100 So we can convert this once again in two to right hand triangles and work it out from there. 11:44.090 --> 11:45.700 We need to know this height. 11:45.900 --> 11:48.980 So it's going to be another square roots Eskew. 11:49.080 --> 11:52.680 So the length along here of course is going to have a base of two. 11:52.680 --> 11:55.170 But this is half of that so it's a one. 11:55.230 --> 11:58.740 So it's going to be something else minus that one. 11:58.740 --> 12:00.680 So let's have a look. 12:00.720 --> 12:05.190 This edge here is going to be a four in length. 12:05.190 --> 12:07.260 So let's pop the four in now. 12:07.290 --> 12:08.060 That's it. 12:08.130 --> 12:09.390 And it needs to be squared. 12:09.390 --> 12:11.520 So this is going to be no. 12:11.540 --> 12:12.070 15. 12:12.090 --> 12:18.090 It's going to be square of 15 16 which is four squared minus one squared which is once the square roots 12:18.420 --> 12:19.650 of 15. 12:19.650 --> 12:20.160 There we go. 12:20.160 --> 12:22.220 So that is going to give us. 12:22.230 --> 12:28.250 And again I can do that here square roots 15 I could delete and extrude I'm not too fast. 12:28.410 --> 12:33.960 But there we go there's ah isosceles triangle where we can make that very quickly and I'm pretty sure 12:33.960 --> 12:36.200 that this length here we should verify that really. 12:36.200 --> 12:41.360 So let's go down in the display options down here. 12:41.550 --> 12:48.180 And at some point here we go air overlays mesh display edge info length. 12:48.510 --> 12:56.040 So if we switch to link here and select that for we can see that the length is four that's quite hard 12:56.040 --> 12:58.570 to see it's a small number on the screen. 12:58.800 --> 13:01.410 But for so we know that that's worked perfectly. 13:01.560 --> 13:10.110 So of course I'm going to guess that himesh I guess triangle or I s missed thing there are a strangle 13:10.530 --> 13:12.530 two by four. 13:13.480 --> 13:14.750 By not point two five. 13:14.770 --> 13:24.100 That's fine I'm going to copy all of that and go ahead and save that as and paste that in a perfect 13:24.600 --> 13:25.300 save. 13:25.600 --> 13:30.840 Okay so the next thing I'm going to do is start with a two while. 13:30.850 --> 13:35.740 Let's start with a different shape to play in this time your hunger to draw it with that Vertex of it's 13:35.740 --> 13:36.980 get rid of him. 13:37.270 --> 13:41.970 And these from our scene go ahead add a mesh. 13:41.970 --> 13:46.870 Alan Skinner had a single vertex and that's going to sit at our origin which is fine. 13:46.870 --> 13:54.670 I went to work in the positive direction so let's extrude this by four in this direction so four in 13:54.670 --> 13:56.740 the wiser Why four. 13:57.070 --> 14:01.590 Let's then extrude that up in the x-axis by three. 14:01.650 --> 14:08.800 That gives us an opportunity of course to create a doorway in the middle and we can create various ways 14:08.800 --> 14:13.630 of doing this in fact because we're working in whole blending units here. 14:13.660 --> 14:18.430 I'm going to abort what I'm doing don't like what I'm doing anymore. 14:18.510 --> 14:23.920 The change it's increments which we can see it's already turned onto and the snapping and just turn 14:23.920 --> 14:25.270 on snapping. 14:25.270 --> 14:31.570 Now what this means is it's going to move in increments which is really nice because I can go across 14:31.570 --> 14:35.580 here extrude and go up by two in the x-axis. 14:35.580 --> 14:36.420 There we go. 14:36.580 --> 14:37.810 Make sure I am still there. 14:37.810 --> 14:42.410 I'm going to view it from the top to prevent funny stuff from happening. 14:44.070 --> 14:46.420 And Claire I'm going to have to make it on its side but that's fine. 14:46.660 --> 14:50.050 I'm going to go to there and then back down. 14:50.350 --> 14:54.030 And then I'm going to go across for the other four now. 14:54.250 --> 14:55.490 Oh that's too far as. 14:55.510 --> 14:57.930 One two three four. 14:57.930 --> 15:00.100 So I should have stopped a bit further. 15:00.330 --> 15:01.320 Oh dear. 15:01.450 --> 15:03.850 So let's pull that back to there. 15:04.000 --> 15:04.770 Perfect. 15:04.810 --> 15:09.580 I don't know how well you can see my grid it's broken up into tenths of blender units at the moment 15:10.330 --> 15:12.460 which is very useful for a placement of course. 15:12.460 --> 15:19.210 Now I can go up by three cross down there and then back to the start point. 15:19.210 --> 15:23.450 Now I'm probably going to have a double there because I didn't turn on Merge vs.. 15:23.440 --> 15:29.080 I'm going to highlight everything before I do anything else and hit space and I'm just going to type 15:29.080 --> 15:30.290 in doubles here. 15:30.630 --> 15:34.510 Robbie hit doubles over the side and there we go remove one vertex. 15:34.510 --> 15:35.710 That's absolutely fine. 15:35.710 --> 15:40.720 Now if I could just make this into one huge n gone at the moment that's not a problem at all. 15:40.810 --> 15:46.100 Or I can make it into smaller ones so this edge on the top I could split up here and here. 15:46.100 --> 15:53.850 I'm just going to fill it in for the moment and then extrude it up by points to five. 15:53.860 --> 15:54.580 So there we go. 15:54.580 --> 15:56.210 That is that one done. 15:56.260 --> 16:01.220 Of course I can put this doorway in the centre if I wanted to but I'm going to leave it like that. 16:01.240 --> 16:05.840 Finally I need to go ahead and name it and save it. 16:05.980 --> 16:10.400 So I'm going to call this s m wall door. 16:12.540 --> 16:20.260 So we know where it is and it is three by four by 2.5 of its height. 16:20.260 --> 16:20.710 Oh oh. 16:20.730 --> 16:22.290 Point two five not 2.5. 16:22.410 --> 16:25.620 So that's height by width by depth. 16:25.860 --> 16:29.580 Just to make sure you guys are following what I'm doing there. 16:29.580 --> 16:31.390 So I'm going to copy that. 16:31.470 --> 16:35.820 Go ahead to here and go in and save. 16:35.820 --> 16:37.990 It's that save hurts. 16:38.280 --> 16:41.680 So we've got we've built up a nice collection of building blocks here. 16:41.730 --> 16:43.650 We're going to use them soon to build some stuff. 16:43.650 --> 16:46.450 But let's start a new file and do a very similar thing. 16:46.620 --> 16:53.280 I can modify that and I think that's going to be far too much to do compared to just adding a new vertex 16:53.790 --> 16:58.020 and this time going through and making it ever so slightly different. 16:58.020 --> 17:00.550 So again I'm going to go in a positive direction here. 17:00.930 --> 17:08.370 And again the orientation might flip that one round later on I'm going to make this one in the way that 17:08.370 --> 17:09.120 I can see here. 17:09.120 --> 17:16.560 So let's turn snapping on incremental on and we want to zoom in just a little and make it four by three 17:16.570 --> 17:23.670 so I'm going to go across by four up by 4 3 which is just there and then back across again before I 17:23.670 --> 17:28.630 make that final one I'm going to merge vertices when they meet one another which is there. 17:28.980 --> 17:36.200 I can just check up here vertices one of five Okay that's not a 3D object which is also good worthwhile 17:36.300 --> 17:40.200 spinning around and checking that shouldn't happen when in orthographic projection but occasionally 17:40.280 --> 17:47.060 does that seem sort of creative 5 for whatever reason so I again am going to remove doubles. 17:47.550 --> 17:49.640 Now a couple of ways you can put a window in here. 17:49.680 --> 17:55.560 I'm going to fill it in first of all when I could insets and have a window there that gives me some 17:55.560 --> 18:01.440 control over what's going on so I can move it in by point one or move it in by a whole blender unit 18:01.470 --> 18:02.940 that's absolutely fine. 18:02.940 --> 18:07.320 I want a bit more control over its placement hand size etc.. 18:07.410 --> 18:11.980 So what I'm going to do here is actually subdivide it someone. 18:12.060 --> 18:12.850 Subdivide. 18:12.840 --> 18:18.270 Once that's not going to give us enough to subdivide it again and literally take out this middle area 18:18.270 --> 18:19.370 here so of there. 18:19.380 --> 18:24.070 There there there or indeed i could do any number of modifications here. 18:24.420 --> 18:24.700 Okay. 18:24.720 --> 18:29.320 Now once I've done that I'm going to hit the x key and delete the faces. 18:29.370 --> 18:30.350 That's those gone. 18:30.570 --> 18:38.170 And we select our entire model and I'm going to extrude it in the z axis by point to five. 18:39.170 --> 18:44.480 That doesn't look like it's moved quite where I want to spin round and have looked. 18:44.520 --> 18:45.980 Yes that's much better. 18:45.980 --> 18:47.220 Now this is a wall. 18:47.240 --> 18:48.680 So it's on its side. 18:48.680 --> 18:54.810 So what we should do here is rotate it so whenever we import it we don't have to keep on rotating it. 18:54.930 --> 18:57.980 We can probably do that with our door section as well. 18:57.980 --> 19:01.570 I'm rapidly rapidly running at a time so I'm just going to rotate this one round. 19:01.580 --> 19:04.160 I need to be an object married at this point. 19:04.160 --> 19:09.180 There we go sir a take on the x axis and it looks like the normals are not quite right here. 19:09.230 --> 19:16.490 I'm going to do that by 90 and I'm going to flip my Normal's hop into edit mode and flip them. 19:16.490 --> 19:18.920 I had that dark blue thing going on. 19:19.040 --> 19:23.890 So there we go we've got a war piece there we just need to do the same for the doors itself. 19:24.870 --> 19:29.700 And there we go we've got some basic assets all made up and saved individually. 19:29.700 --> 19:30.980 How did you guys get on. 19:30.980 --> 19:34.740 Did you make a slightly different variants on these assets. 19:34.740 --> 19:38.930 Please share in the discussions and I will see you in the next lecture.
