All right now that we took a look at how to subdivide or mash and add more geometry Let's take a look
at another way to do this hitting tab to go into edit mode.
Another way that we could do this because when you subdivide it actually adds geometry everywhere to
the mesh.
And what we want to do here is actually it's called the extrusions so we could extrude or pull out certain
parts of the mesh.
So if I had control tab to go into face like mode and then select a face by right clicking on it if
I hit the key.
You can see that extruder it and brings it out pretty awesome so you can actually start to bring out
parts of your mesh.
And you could do that anywhere that you want you could actually select multiple parts by shift right
clicking and extruding it out.
And this is really cool and adds geometry very fast exactly where you want to add geometry.
Now a thing to keep in mind is as I mentioned previously with the subdividing I do want to go back on
one thing quickly for the subdividing because I guess that most things are for vertices or faces of
four vertices.
If I select this whole thing and hit w and subdivide that's fine because the faces I still have four
vertices on them but if I just select one face and hit w subdivide you can see that these right here
are fine because these have four vertices but this face right here now has five vertices.
So it's a little tricky because now it has and if it's not animated it's usually fine it's usually when
things are animated that you don't want to have this or in other regards as well because it could give
some weird artifacts to the object.
We can see that right here there's five vertices for that one face which is not that good.
It's usually not good.
So keep in mind that when you subdivided you could subdivide individually as well individual faces.
But keep in mind that might not create a good result.
So you usually don't want to do that.
If I control Z to undo all that I now want to show you what you could do with extrusion which is really
cool.
If we select a face and hit eata extrude it automatically brings along this axis.
However left click will confirm.
But if we hit the right mouse button it will actually place it back to the center.
And you think that nothing has happened that nothing has been extruded but it has it's just on top of
the previous mesh that we have before.
If we hit the Eski Now you can see that we're able to scale it.
And how awesome is that.
So we've just created like kind of invert into our face right here and you could see that these faces
still have four vertices each.
And so that is awesome.
It's a proper mesh.
It's still flowing nicely.
So that's another way that you could add faces with the extrusion tool because now you could scale this
down.
And then you could extrude this part out by hitting e you and then if you want to scale it back up you
could hit you to extrude and and so bring it out right click to de-select it as to scale it up and just
bring it forward a little bit and you see that now it's extruded out and it's scaled up and then you
can hit it once again to extrude it.
So that is the extrusion tool.
You could also use the extrude to extrude vertices of single vertices.
So let's do that actually right away.
For hair control have to go on the Virtex like mode I still like this vertex and this one or actually
that would be a face.
So let's just select one of our it would be an edge.
You could also extrude edges of course if I like this edge and hit you to extrude and then Zeeuw to
constrain on the z axis you can see I've extruded an edge now.
Now let's extrude a vertex let's like this one hit enough to extrude and then Z to constraining on the
z axis.
And now we have a vertex.
Pretty awesome.
And just like before we could actually fill in a face.
Let's say for example you want to fill in a face here.
We can do that by just shift right clicking these vertices here and then hitting f fill in that face.
Now we can bring this one down a tiny bit.
So extrusion is super useful and it's very very practical.
There is a lot of different things you can do.
And you know it's a really great tool to add geometry to your mesh without having to subdivide the whole
mesh entirely.
Extrusion is actually one of the most used tools to add geometry to your mesh when you're creating a
human face or an animal or literally any object you're going to be using extrusion probably 90 percent
of the time to add geometry to your mash.
So this is the one that you want to be using because it gives you precision and gives you control.
And you know what you're doing.
Whereas if you select everything and subdivide it lets say you only wanted to add geometry here.
Now you have geometry are added all over your cube.
And like I said all of this here is unnecessary.
You only wanted extra geometry here.
So that is extrude tour.
It's really awesome.
It's fun to use and it gives you some great results to be able to extrude and add different parts to
the mesh.
All right.
And our quote for the end of this video is you have much more potential within.
However in order to tap into that potential you must believe in a reality that is not currently present
which to most is tricky.
You see what you think is reality is only your current perception of the world.
Everyone is experiencing a different reality.
Expand your awareness and you'll see that what you thought was reality was only a drop in the ocean
but not the whole ocean.
There are infinite number of realities that we can choose from.
It's your responsibility to choose one that brings you to where you want to be.
All right you have an infinite number of realities within you.
You have the potential of being an amazing artist or what ever you choose to be.
So just pull out that reality from you and live it every single day.
Appreciate you guys.
I'll see you in the next video.
