Amongst the other larger enhancements, the Voronoi Fracture generator in Cinema 4D
Release 19 has received two more settings that, although seemingly small,
actually offer great new creative opportunities for procedural setups.
These are the "Invert" checkbox and "Thickness Parameter." Let's take a look
at what they do. Let's begin with a simple sphere primitive. I'm going to
make it bigger, bring it over here, so we can zoom in and have a better look.
Turn on my "Gouraud Shading" lines, and now let's create a Voronoi
Fracture object and make the sphere a child. So we have our typical
broken up sphere. Let's select the Voronoi Fracture object and in the object tab,
which I'll bring the whole attribute manager up, we can see that we have the
"Invert"checkbox, and the "Thickness Parameter" right over here.
These didn't exist in Release 18. Let's see what happens, because currently
they're inactive. In order for the invert to work, we need to have an offset in our
fragment. So, let me type in five, and create this gap. So you'll know what this
does. It actually shrinks the fragments down so there's a gap between them without
changing the shape of our fractured object. Now, if I click "Invert",
look at this. This is actually the model of the gap itself. And this allows you to
create amazing lattice type objects. So we can go to the Voronoi Fracture,
let's go to the "Sources", and increase the number to something like 400.
Let it break down, and now go to the Voronoi Fracture object. Let's make this
one. And now you can see that we have this amazing looking object.
Fantastic. Let me go and turn on my screen space ambient occlusion to get a better
look at the model. Now let's move on and see what the thickness does.
Now, we can click "Hull only," and this will give us the surface of the gap,
which already this is a very interesting shape. Now, if I go to the Voronoi
Fracture...and as usual I want to turn this off because those little green dots
just irritate me. Go back to the "Object" tab. And now what we can do is increase
the thickness when we turn "Hull only" on, then the thickness is active.
I'm going to put 10 here, and press Enter. And you will see that this adds a
thickness. Let me quickly show you how you can combine some of these techniques we've
learned in this series to create an interesting effect. The effect of that
breaking apart soccer ball. So, I'm going to create a sphere, and set the actual
type to "Icosahedron" so it's all triangles. I'm going to create a Voronoi
Fracture, drag the sphere, break it apart. But what I'm going to do now,
is select the Voronoi Fracture, go to the "Sources", and delete the default point
generation. And what I'm going to do, is take the object itself,
drag it in here, and make sure that the creation method is based on vertices,
and turn off the points. And you can see we have these hexagons.
So, let's see what we can do now with the new features. Go to "Object,"
let's offset this by 5, and invert it. So we can create these rounded honeycombs,
but if you don't want to, you just go "Hull only." I'm going to make sure that
the sphere is around 12, so we have these bigger hexagons. And then what I'm going
to do is add some thickness. Let's say 3. Great. Let me turn off the colorization.
I'm going to go to my "Transform," make it gray so I can see it a bit better.
And now we have all these separate fragments that resemble some sort of
hexagonal shape. And of course you can go and play around with how much distance you
want between these fragments. If you'd rather have a much more smooth soccer
ball, what you can do is the following. Make a copy of this sphere,
so drag it pressing your command or Ctrl key. Go to this sphere here,
and let's increase this to something like 48. But because I used this sphere as my
source, I'm going to get rid of this sphere and drag in this sphere.
So now we have the same hexagonal patterns, but our soccer ball is much
rounder. Between doing this and other combinations of the new enhancements of
the Voronoi Fracture generator in Cinema 4D Release 19, I'm pretty confident that
very soon we're going to see some fantastic motion graphics and art-work
being done with it.
