Hello, everyone. Welcome to the first part of the first assignment where we're going to make the wine bottle and glass shapes using splines, we using spline modeling for this assignment. And the first thing you want to do is really just go to Google search for wine bottle. And I think this one's really nice to start as a reference. And obviously, I want you all to create your own bottle shape, but I want to give you the tools to do it on your own. So start with this.

I'm gonna go and just save this image and go like that. And then from there, I'm coming to cinema. And the way to do that I like at least is to Drop a plain object in and put the image of the bottle here for reference. I'm going to change it to plus z and the orientation for the plane so it sits up right. You could also just rotate it to. So we have a plane right there.

We go in here and make a new material by just double clicking in here. In the gray area, a new material gets created. Then we go into the color channel. And inside the texture field, you can just click on this right here and it brings up a dialog box for loading an image. I'm just gonna go and load it. Don't worry about this.

I always say no. So it gets dropped in there. And I now I can just drag this material onto the plane object and there we go. Now, by default as a new material it got it has the color and the reflectance channel turned on. We don't need the reflectance channel to turn on. For this because it's a reference image, it's gonna make it actually easier to see, as you can see how it gets washed out when it's turned on, because it's reflecting a surface, we don't need that it's a reference image.

So I just turn it off, so you need to worry about that. Because the Rotate tool if it's upside down and just rotate it and there we go, there's our reference image. Now, one thing about spline modeling is it has to be done in a two dimensional view. I'll show you why. Now if you go up here, so next to the polygon primitive menu. These are the spline primitives that you can drop in.

And splines are really just they're 3d lines. They won't render. But because they don't really have any volume. But they, they're really powerful ways of creating objects. And it's really it kind of it's based off the same principle is, you know, a path, like the path tool in Illustrator or the pen tool in Photoshop, where you can draw lines, but the points and the handles in that line, they all have 3d coordinates. So I can show you right now what that's like.

I go to the pen tool right here. Just like that. I can start making a spline. Now obviously, if you click and drag just like an illustrator, you can drag handles, if you don't drag, it'll just make hard points. Like that. And then you can connect them together and it's a closed spline object.

Now the reason why I don't want to do it in 3d is because of this. Now what it was doing was it was making a path perpendicular to the camera view. And whenever that was, when you started making a spline, it's, you know, it ends up being flat. But it's only it's flat perpendicular to the view when it was created. And that's really not what you want, because it ends up being at some weird angle all the time. And you don't want to spend the time trying to put the camera view exactly perpendicular to a plane, all that kind of stuff.

It's really just it would be really frustrating to get it right. And then two dimensional views do a really good job of of keeping it flat. But I do want to show you when the spline object like this gets created, you can go to the live selection tool and actually select these points and move them around in three dimensions. So that's a really cool way of moving lines around. And splines, as 3d lines are actually a really powerful tool for modeling. So anyway, delete that.

We go into two dimensional view, which is up here, this button. I like to go right now at least to the front view. And you can see you see this kind of grid right here. This is actually the plane object, if I select that you can see but it is not being shown because of the display mode that default in two dimensional view. And if you go to the display drop down right here, you can see it's set to lines. Now, in the perspective you go back to this display mode is set to grow shading and That would be, this is the lines view in the perspective, viewport.

And so just want to go back into two dimensional view. And you can see right in this top left corner of each of these windows, there's the right front and top view and then the Perspective view. So in the front view, that's a great place to start doing a spline object, we need to make sure we can see the bottle so if we go to display mode and change it from lines to grow, it shows up. Now the one thing about two dimensional views is if you hold down all the left mouse button, this happens, which can be really annoying. So just make sure that you don't rotate like that and into dimensional view. But anyway, so we have the reference image set.

We just need to go to the pen tool and start making a profile of this wine bottle Now I want to show you real quick, what tool we're going to use to make this one bottle. And it's right here and the next menu, it's called laid. Now the laid the sweep and extrude. And loft objects are all spline modeling objects, and they're really powerful. So I want to show you what the layout object does. So we'll start real quick.

And just I'll just make a really rough wine bottle like that. Now if I go back to the Perspective view, you can see how that spline has now is now laying exactly at the origin of his of the z axis. And it's just using the x and y coordinates. So it's basically a two dimensional object in three dimensional space at this point because there's No z coordinates. And that's exactly what you want. So I'm going to uncheck this plane object real quick and just show you what a layout object does.

So lay the object will spin a spline profile, which is what this is around in, in 360 degrees. And the way you do that is you try to lay the object in and make the spline profile a child of that. And then this happens. Now it's not a wine bottle. Only because the late object starts at the origin by default and that is the axis that it spins around. So because the spline profile is so far away from the axis, it turns out looking more like a bowl or something.

And what you want to do before you start making a wine bottle, or at least when you start making the problem For the wine bottle, it needs to be in the center like this around the y axis. So now when I drop this in to delay the object, it becomes more like a bottle. It's important to note the child the spline object of the lead can also be moved in and out. So it can be a little bit annoying by accident to to move this wine bottle like this and not know how to fix it, that's just because the spline profile itself is moved away from the origin and the y axis. And that's kind of why it does that. So you want to make sure that your spline profile of the wine bottle starts very close to the origin.

And I'll show you as we get farther along how to make sure That this point, the beginning point and the end point of the bottle, lay exactly on the X origin at zero, because that because if that doesn't, if they're not sitting there at the origin, this is what happens, this little hole right here. I go into the fight going from object mode to point mode, I can actually start selecting these spline points and move them around if I want to. But it's really hard, it can be really frustrating to try and make sure that this point lays exactly at zero. If you go this far this happens. And then if you don't meet exactly in the middle, then you have a little hole. And that's also really annoying.

But basically, this is what a lathe object does. It's really nice. It takes a profile of a shape and it spins it around 360 and then that's how you get really nice cylindrical objects that you can you know, customize So start with that until the spline and go back into the front view and just kind of make a rough shape of this one bottle. Give us the pen tool and I'm going to start at the bottom of the bottle right here. The triangle right here, handle right here. This will be refined later.

Okay, so that's basically very rough profile that one bottle. Now you don't want to connect these two, because once it gets spun around with the layer object, that'll be the part where it becomes a whole bottle. Now before I just say no, I mean, it's rough, so this is not going to be exact, but if I go into layout object, and you can change the angle, down or up from 360, if I bring it down to 180, you can see how this bottle is kind of is cut in half. So you can see inside of the wine bottle, and this is the part that's going to be filled in with glass and this is obviously the part where the one goes. So this is the only part that really gets connected together because this is going to be Spin around and become the lip of the wine bottle.

So it's not, you shouldn't have to, you shouldn't close the spine profile at all. Just make sure that these two points meet exactly at zero. So when it gets filled in like this, it ends up becoming a whole bottle and I'll show you how to do that a little bit. So there we have a pretty, you know, pretty rough wine bottle profile. And you can just go back using that image as a reference is really all it's needed at this point. And you can go from here and just make it your own bottle.

So I'm gonna go back into the spline, and you can see how the points show up because I'm in point mode, as opposed to object mode, or model mode. To point mode for a spline is when you can start to mess around with these shapes. These points, it's cool because it updates live as well. When these points get moved, and the cool part about splines and these handles is I can actually use the scale and rotate tools on these handles too. So I can rotate the handle like this. And then I can scale it up and down to make the handle longer and shorter proportionally with the Scale tool.

So it's a nice way of kind of precisely using those tools for splines. And obviously, you can still in a two dimensional view, mess with the handles like this too, if you want, just like you wouldn't know illustrator or Photoshop. So there's two different options on how to manipulate these points on these handles. So first of all, I'm going to take this one, okay, so even though it's a is a tiny handle, I didn't really want this to be a soft edge, I wanted it to be a hard edge like this one. And it's easy to change from a soft to a hard edge. If you just select that point and right click, you can change it from soft interpolation to hard interpolation.

So I'm going to click on interpolation to make it a hard edge like that. And then I'm going to bring this down, like that. And I'm just going to push these points around until it becomes more of a of a bottle shape that I like. Now the cool part too is I can select multiple points like this, move them and rotate them to like that. And I can also scale these down if I wanted to, proportionately so I'm gonna actually wrote I'm gonna select all four of these and scale them like this just to kind of get the lift To be a little bit skinnier, and then go back to these two points, and I'm just gonna move them in. So it's, it's more of a, you know, subtle lip.

And then what I want to do is this trick called chamfer. And it's a nice way of, instead of having these really hard edges for these sections of the bottle, and I want them to be soft, I don't want them to be to have handles like a stop interpolation. I want them to be more like kind of beveled with a round edge. And that's what chamfer does. So I can actually select these four points, like this, right click, because I'm in point mode and Sam for them. So when I select that tool, and I click and drag the selection that happens now Really nice to have.

So now it becomes a really nice rounded edge. But it's not, it doesn't have handles, it's like a, it's like a soft bevel. And that's a really nice way of, of just kind of adding in really easy bevel edge to a lot of these hard edges. because realistically, even though glass can be really sharp, not ever gonna really have a completely hard edge like this, there's gonna be a little bit of a roundness to it. And it actually it's nice too, because it those rounded edges, end up catching light. And they kind of add to a really nice, you know, just really realism.

Okay, so, same with this top part. I'm going to right click these two points and shout for them as well. Give the bottle a little bubble like that. That's really nice. I think even though it's it's pretty good would still just want to tweak this handle to be a little bit more kind of follow the outer handle too Like it. Now these two points right here need to be exactly zero.

And I'll show you what, how that's done really easily. Because you can see if I do that, you know, it does that, which is, which is not good. So the best way to do that is to manually type in the coordinates of each of these points, or this point in this point, really. And that is done in the structure tab right here. Now structure tab is really cool. It's a little bit it can be pretty in the weeds, too.

But basically, it tells, it can tell you the exact coordinates of every point in a spline object or anything in a polygon object. And so it's possible to manually type in any coordinate that you need of any point. And that's, you know, that's really cool. You don't really need it that much. But it comes in super handy for stuff like this because this has to be exactly at zero for this object to become a closed volume. And for it to become a refractive object of glass, like we'd like it to be.

Because if there isn't, if there's a hole in this, the refraction is not gonna work, because it's technically not a closed volume it it has an open edge to it, and then the math refracting doesn't make any pills, it'll start to flip out and get really, you know, weird results. Anyway, so he's going to do is to just have that point selected, and obviously it'll, it'll highlight whatever point you have selected in this view. it'll, it'll, it'll show you where that is in this in this like, list of points. So I can just select this one, which happens to be the last point in this line. And you can see right here and the x coordinate is point eight, seven inches off of zero. If I'm checking if I move this, you can see how it changes.

That's really nice. So I'm just gonna go in here and double click, and then type in zero, and it moves exactly to zero. And this one 2.4 point five, four inches off of zero, double click that and hit zero. And boom. Now those two points are exactly at zero, and there's no question. It's very nice.

And now you have a wine bottle. To go back to perspective, you can see that we go into the object tab and then lay the object right here and just type in 360 for the angle, it becomes a full bottle and that's pretty much a wine bottle right there. playback on can was delayed object over. So what I did just say no, I had to lay the object selected when I moved because if I if I ended up moving the spline object this happens. So yeah, just make sure the layout object is selected when you want to move and it'll move around. But I'm actually going to move the plane instead.

Now this is this is a prospective image. So that's where that curvature comes from, you know, it's kind of more like it's looking down on the bottle. And so that's I didn't end up following this curvature. It'll be recreated when we frame the shot. But that's all there and it'll be nice Nice and transparent, and look really nice when we put the glass material on it. One thing too You can see how it's got these hard edges.

That's because the amount in the layout object, the subdivisions are set to 24 by default. And if I go into the display mode and change it from gross shading to gross shading with lines, that'll show you all the lines that are making up this polygon. This law it's a polygon object technically, but it's actually a it's a spline generated object. But you're able to see all the lines that make this up and there aren't enough right now to give it like that organic shape. And all you have to do is go into the layout object and just kind of scrub upward on the subdivision that you can see how it increases and you can do a lot really kind of need to to make it realistic organic shape. And it's still possible to go into the spline object right now and make sure you're in point mode to select these points in the Perspective view and and move them around, what you can't do is say I wanted it to be more of a bubble.

If you did that, you kind of not really getting the right. It's not a very accurate bevel anymore, because the chamfer was created only for that distance that was dragged when that point was selected. So say you want to go back and increase the amount of bevel and one way to really do that is to select two of the I mean, we'll select one point out of the Sham for that and then delete it and kind of start over. So like, select that one point, delete it and then have the other Points selected and go from soft to hard interpolation to make it a hard edge again, the same thing on the other one like that, and you can use back to beginning again. And then you can go and select these two points and right click and chamfer them to your heart's content. Maybe like that.

And even obviously, at this point, you can go into the Perspective view and have those points selected and do it there to see how much you want. Could be like that. So there we go. That's how you would kind of edit your sanfur you just kind of start over again. That's a pretty good wine bottle. I want to show you to right now the Access Center for this one bottle for the lay of the land.

Because at the origin, which is obviously not where the bottle is right now. And if you wanted to, if you wanted to manually change this Access Center to do whatever you wanted, you can do this. And it can be down in perspective YouTube, but this also helps. So in the two dimensional view, you have the axis selected, and you have the object selected. And you can be in point mode or anything else. But I'm just going to object mode to show you so you have the layout objects selected, you're in object mode, and go to this button right here, the access modification mode.

Now when you select that, it just turns on. And instead of this moving the object, you're just actually placing the Access Center wherever you want, and it can be anywhere it could be, you know, over there, you're just gonna totally mess everything up. But if you just want to drag it upwards to be wherever you want, I'm going to put it right at the bottom of the one bottle like that. Which is what's that's what's helpful about two dimensional view is, it's easy it is to play stuff like that. Go back here. Now I can't move it around until I turn off access mode.

Now this will become the way I move the objects around. And so now that it said exactly the bottom of the one bottle, I can go into the layout object coordinates tab and manually type in zero in the y direction, and it'll sit exactly at the origin. Now the next section will do the wineglasses
