Okay, so here we are with another unit, and it's gonna be more circles. I know I know. But let me ask you, do you know what 3d means? No. Okay, like three dimensional. So we have 2d, which is kind of a flat object, right?

And then we have 3d. That means depth there. There's depth to that object. There's dimension to it. Okay? This is easy when we think of squares and cubes.

But when it comes to a circle, do you know what a 3d circle is? a sphere or like a ball? That's kind of exactly and that's maybe helping you that you're looking at the basketball on my screen right now. Yeah, that might be it right. But, you know, how do we know it? Something is a sphere, as opposed to just a circle, right?

How do we give it depth and stuff, right? Well when we look at this basketball, and let's see if we can kind of make it really big right now, there we go. You know, we've got texture, we've got to kind of the shading and stuff. And all of that's going to help in making it feel like it's 3d and stuff. But one of the things that we're going to study today is called a circumference line. And that is, think of the word circumference like circle.

Okay, so our Circle line, and right now it's kind of hard to see on this ball, but this middle line here, going straight up and down, is actually a circumference line. Oh, now this looks straight up and down, right? And this looks straight side to side, like this is called horizontal and this is vertical. But I can move this ball and you're going to see that vertical line. Actually, what it does is it starts to bend we can see it bending as it goes around this ball. Yeah, right.

Okay. So As I move it back to the center, we can see that it's a center line right now, right? It's just a straight line. But as soon as it goes off center, well, here's where that center line would be. But this is starting to bend. And we know that a balls round and stuff like that.

So this, this bending gives that kind of that nice 3d shape and stuff I get, right. So even if I don't have the the shadows in yet, even if I don't have these, you know, little highlights and stuff from the lighting and everything like that, just looking at this circumference, line me gives us the feeling that I'm turning it from side to side. If there were no lines on this ball, and we're turning it from side to side, we really wouldn't see what was going on. It would be hard to see it turning right. And like I said, we've got this middle line, going through the center horizon, right, the horizontal one, and it can go down and back up and we can see how the ball looks like it's tilting downward and tilting up. Okay, does that make sense?

So what we're going to try to do Do this in a bit of an exercise. Oh, yeah. I'm gonna get rid of this ugly bowl. And Okay, so what we're going to do is get on into our piece of paper here and draw some of these circumference lines. Okay, so let me go first. What I want to do is same as how we were practicing Last time, we were doing some circles, right?

And why don't we just lay out a few circles here in a row. If you want to, you can follow along with me. They don't have to be perfect or anything right. Okay, go ahead. Yep. Yeah, those definitely aren't perfect.

No need to make you insecure about my circles. don't fit some noise. They get worse and it's okay. They won't be perfect. It's cool. Okay, so we've got a few circles in a row now.

And on this first circle I want you to draw, cut it in half, using that kind of middle circumference line that that vertical one that we had talked about, right? So imagine if that was that basketball, right? Remember the basketball that we saw, we want to have it cut straight up and down. Okay? Now imagine this basketball is in your hand and you start to turn it. So we've got where that starts from the top right, kind of hearing here, but as we start to turn that ball around, it's gonna have some slight bend to it, that that middle circumference line, okay.

So the easy way to mark it is, you know, use these little markers at the top and bottom, because that's generally where it's going to start from, according to our eye, okay. And as we bend it more is going to wrap more around this ball, right still using these these markings. Middle markers and stuff. And even more as we wrap it around even more, right, okay. Still using these marks there. Okay, so we can go below and draw another roll of circles home.

I'm ugly here. Ah, yes me, I think you gave me some disease with that minor turning out pretty good. Okay. It doesn't matter whether you have three or four here, it's okay. The first one, we're going to cut it in half horizontally now. Right?

And then we're going to use that kind of horizontal, you know that the little marker. And imagine if I'm just turning my bowl downward a little bit, right. Turning it down even more. I can go even more here, right. So now all of a sudden this is instead of feeling like a straight circle. These are stunning.

To feel like spheres like balls severes years I cannot spheres, fears. Okay, good enough. Yeah. So this is what we're going to do on our page here. We're going to draw more circles and I know by now you're probably in love with, with me making you draw circles and stuff, right? gonna draw heaps of circles, okay?

You can draw rows upon rows of them more. I don't know, I only did three extra well eventually we're gonna fill up these pages and stuff right like it. You don't have to fill it up today. That's not the point. It's it's getting comfortable with this practice, right? So if you're some massive genius, not take you a few.

Oh, I'm in trouble. Now. It might only take you a few tries. But you know, honestly, it shouldn't take that long. Yeah, that's okay. Okay, so what are you going to try to do is just practices, draw a middle line, and then start, you know, if you want to, you can even rough in with that middle line would be across the board and then start to rough it that is bending, bending more bending all the way or something.

And then eventually, probably on my little scale here, I would have had one more, and that middle line would have bent all the way around like that. Okay, so you're, you're straight, you're turning a little bit, turning some more turning some more and turned all the way to the side there. Yeah. Yeah. What do you think? How's it feeling free?

It's, it's harder than just drawing circles. Oh, yeah. Oh, definitely. circles are just, you know, flat 2d objects, right? And so the same thing is, you know, you're going to cut the next line, I want you to practice it again. Right.

Turning it down, turning it down some more, turning it down some more and, you know, eventually if my circle is not To ugly, it'll eventually come all the way down to the bottom. Right. Okay. need to fix? Yeah, you know, if you're drawing ovals and stuff like that things are gonna look lopsided, you know, they're gonna look a little wonky little often stuff. And so the better the closer you are to a reasonable circle, the more reasonable these spheres are going to turn out, right?

You know, they're, they're just gonna look better and stuff, right? So that's why that previous unit of practicing circles, I know it was a little boring, or it could be if you do it forever, right? But if you catch it pretty quick, you know if your circles get decent and stuff I got it'll roll pretty decently. Okay, so we're a couple minutes into this now. And we're almost done this particular unit, but on the last bit of it for homework. Yes, I'm giving homework.

I want you to play with it even more. But imagine you've got a line going down vertically and a line going horizontally. And now you start to turn these balls in whatever direction you want them to turn. Right? It's, you have this basketball in your hand, and it's turning to the right here. And it's turning down a little bit, or this one's turning to the right.

And this one's turning up a little bit, right? I think you can kind of get what's going on here. This is going to be eventually we're going to look at it like an eyeball or something like that, right? That type of thing. Okay. So you know, turn to the left, turn way down, right?

Turn way to the right, and turn way up top, right, so you get this kind of that center point there, right. So if here's the center point, that's what you're kind of always hunting for. You're hunting for turning it in there. There's that central point, right. So So this is your homework, you can start to fill up your page. I'll keep going.

But I don't have room on your page. And you know what happened when you run out of room? Start a new page, you know, grab a new scrap piece of paper or whatever it is, and just start filling them up. Looking good. Oh, this reminds me if you said it was like curling an eyeball. Like how you look at a face?

Yeah, this you know what? I know that when we're talking about basic shapes here and stuff I got people were like, yeah, yeah, I can draw a circle. I can draw severe blah, blah, blah. If you really master some of these basic shapes that are in this course, you know, in this basics course. It will make everything so much easier when you go on to drawing shapes and bodies and cars and whatever and stuff right? But um, this is my fair warning.

This is my parental warning. That's my dad voice right? If you think you're going to skip over this and you think, you know, this is not important and everything, you're going to get hammered when it comes to the other courses, it's going to be way too tough. Okay? So spend the time now. Take the time to draw out these things and you know, you can kind of fool around and put a little X on it or eyeball or whatever it is, right?

But fill up that page full of these fears. fears, fears. Don't fear the spheres. Oh, that's a good slogan. Okay, that's it for this one, guys. Have fun.
