Textura en esferas | Mediateca de EducaMadrid

hello everyone we're going to start this exercise talking about the concept of texture 00:00:00

as you can see texture is going to allow us as you can see here in these examples 00:00:10

that i've shown you these balls here those spheres sphere 00:00:16

Spanish esfera 00:00:22

or said in plain English 00:00:25

bola, pelota, whatever you want to 00:00:31

so as you can see here in these three examples of us 00:00:35

we have some furry 00:00:40

fur, peludo 00:00:42

something more woolly 00:00:46

Let's write it. Wooly. Basically it's woolly. As a sheep. Okay. As a sheep. You probably know what a sheep is. Okay. That's a sheep. Okay. That's basically a sheep. Okay. So sheep. They have a woolly body. As the sphere here. And finally spiky. Spiky. 00:00:50

spiky, you know, a spike, it's a pincho, okay, it's a spike, so a spiky texture, as you can see here, 00:01:19

is a shape which is very tightly spiked, okay, I have a lot of spikes, so for each and every one 00:01:31

of those spheres, we have this texture that in our eyes, in our perception, 00:01:43

our nostros ojos they're going to feel in our fingers very differently so the same thing here 00:01:49

this is going to be felt as something soft even this one here the woolly even possibly softer 00:01:58

this one appears in front of us as something quite dangerous and possibly painful so how we are going 00:02:06

to get this three-dimensional texture into a shape as a sphere so that we also use the texture 00:02:16

for making that three-dimension feeling that three-dimension perception stronger 00:02:28

we're going to start as it couldn't be any other way drawing a sphere as you can see here 00:02:38

I am drawing a rounded shape with a hard pencil. I could do the same thing with a 00:02:46

softer pencil. It doesn't matter. Now I'm going to shift into a felt pen. It could 00:02:54

be a thinner felt pen as the one that I'm going to use now. And I'm going to 00:03:04

start using a furry texture so that fur in a three-dimensional object as a sphere we're going 00:03:09

to draw it so all the hairs okay they're going to be showing they're going to be directed into 00:03:22

the center okay that's the center of the sphere so across the boundary the exterior boundary 00:03:32

we are going to draw rather long hairs and those hairs are going to be rather close to one another 00:03:42

and then in the inside of the sphere we're going to draw another layer another layer 00:03:52

another layer of hairs only this time those hairs that i'm drawing they are going to be 00:04:06

very slightly very slightly shorter slightly shorter slightly shorter what does that mean 00:04:19

so we're going to do the same thing with another layer here okay another layer of hairs 00:04:36

and also these hairs they're also going to get gradually gradually okay they're going to get 00:04:49

gradually more separated separated okay so in the outside as i told you before the hairs the fur 00:05:02

it's going to be tighter, it's going to be tighter, tighter is more than just only tight, 00:05:19

okay, tight, está junto, vale, tighter, vale, más junto todavía, okay, so it's going to get 00:05:30

tighter at the outside and gradually they're going to be more separated in 00:05:43

the inside of this fur ball something like this and also gradually those hairs 00:05:51

here in the inside they need to become shorter more separated gradually more 00:06:01

separated and gradually they got to be get shorter how short they need to get shorter till 00:06:11

we just only have some points okay they are not straight lines anymore but they become dots dots 00:06:20

okay a dot is basically the same as a point okay point has also a geometrical sense and dot 00:06:30

is just only the mark of it la marca vale es un punto y point es punto geometrico 00:06:44

vale esto es simplemente la marca y esto tiene un valor geométrico we're going to get into that 00:06:53

a little bit later yet as you can see by using this technique what was initially only just 00:07:04

a two-dimensional circle now becomes quite easily and quite quickly and fast a three-dimensional 00:07:15

furry shape as the one that you are watching right now that makes sense if we get for instance into 00:07:29

this three-dimensional model you see also here we have a spiky texture and yet as you can see 00:07:37

the spikes that are at the outside as you can see here at the outside of the sphere 00:07:46

they are longer and they seem to be tighter than this than the spikes that are in the inside 00:07:52

of of our sphere so according to this perception model okay as you can see it doesn't matter 00:08:01

from what point of view we watch the sphere it's going to be all the time the same 00:08:08

perception. The outside, longer 00:08:17

elements. The outside, they are more 00:08:21

separated and shorter. And according to this 00:08:25

model, to this pattern 00:08:29

to this pattern 00:08:32

each time it will be more separated and it will be smaller, okay, according to that, if we do that, we will always be able to have 00:08:50

this type of textures, okay, thank you very much for your attention and until the next video 00:09:02
