If
you want to keep the number of pixels down to
reasonable levels than apply
‘Reduction’. |
Emboss
Emboss takes an ordinary IFF format image file,
and uses it to create a three dimensional object.
Rather than mapping the image onto the outside of
an object, an entirely new object is created. The
object starts off as a flat plane, but the
average value of the Red, Blue and Green
components of the individual pixels are used to
determine the height at any point. It should be
remembered that even a relatively small image
(say, 320 by 256 pixels) will generate far too
many triangular facets for C4D to cope with, so
the ‘Reduction’ setting is supplied to
reduce the pixel count to more manageable levels. |

Take
a wonderful photograph, and use it to create a
greyscale height map. |
Emboss
can be used for special effects, or for more
mundane chores such as creating a landscape.
Unlike the Fractal system, Emboss enables you to
plan your landscape down to the smallest detail.
Remember too that you can map the original (or a
different) image onto the object.
Figure
When creating 3D scenes, it’s often
desirable to have a human being present to
provide a sense of scale. This is especially true
if you are designing a building, room, car or
other ‘real world’ object.
C4D makes it easy to add a human being by doing
all the hard work for you – you only need to
select ‘Figure’. |
![](cinema4.gif) |
![](cinema5.gif) Combine the two by mapping the
photograph over the embossed object and it’s
enough to put you off your lunch!
|
What’s more,
it’s very easy to pose the figure because it
has already been defined as an
‘Animation-ready’ object. When you
select the Drag function in the main toolbar (the
three arrow button) you can easily rotate the
figure in a realistic way. Select the arm joint,
and the entire arm including the hand will move.
Select the torso, and the head, chest and arms
will all move as well.
Fractal
Instant craggy islands are
possible with the Fractal tool. This will create
a random object which is perfect for all manner
of landscapes: even lunar surfaces or gently
rolling hills. |
![](cinema7.gif)
The default settings will create a very hilly
object: try lowering the height for more
realistic effects. |
The
Fractal object is complicated, but you can speed
up the redrawing from the Object Manager window.
For a nice effect, map a texture onto the fractal
as this gives the impression of even more detail. |
You can select
the size of the new object, as well as the height
and coarseness of the facets used to make it up.
You will need to experiment with the settings:
create mountains which are too high and the
effect is an alien world. Remember that you can
treat the fractal object like any other, and so
you can apply textures or adjust the attributes.
You can also deform the fractal and adjust
individual points.
Sun
If you are too lazy to create a light source, or
if you want to accurately model an outdoor scene,
than C4D has the perfect solution: the Sun. By
creating a sun object, you are creating a
lightsource whose position can be altered to suit
the time of day, day of the year and location:
perfect for architects. The sun is not white but
pale yellow. As it nears the horizon it will
become more red, as it does in the ‘real
world’. |
![](cinema10.gif) Text
can be entered in the requestor or
stored in a plain text file: useful if you
want a long list with a new line taken
after each.

Create your own mega-epic
scrolling titles with ease using Cinema 4D’s
text option. |
Text
The Text object is a bit of a cheat, as it makes
use of a set of predefined objects rather than
generating font objects on the fly. However, it
still works and is ideal for creating images for
video work. The message you want to render can
either be entered by hand, or read from a plain
text file. Use the text file when you need to
create long messages (“In a galaxy a long
way away...”)
and then move them slowly into the distance and
into a slight fog for a wonderfully expensive
looking effect.Two different fonts are supplied:
Diamond and Helvetica, although there is nothing
to stop you designing your own. To do this you
should create a new directory, and inside build
all the objects you need, saving them as the name
of the letter they represent. For example, the
object for the lower-case letter ‘a’
would be saved with the filename of
‘a’. You will also need to create a
file called ‘Description’ which
contains information on the size and spacing of
the letters – see the files created for the
existing fonts for details. |

Use the Object Window to quickly switch
the ground on and off. If you switch it off,
your objects won’t fall anywhere –
they’ll simply float in space. |
![](cinema13.gif) Adding a little fog from the Environment
Window makes all the difference to this scene,
and provides a real sense of depth.
|
Ground
If you need a surface on which to place your
objects, look no further than the ground.
Sometimes you need to create your own object
– a desktop for example – but if you
need something solid then the instant ground
object is for you. The easiest way to use it, is
to open up the Object Toolbar – although the
menu option under Objects will achieve exactly
the same thing. Even though the ground is
switched on, you won’t actually see it
untilyou perform a render or specifically select
it. If you do wish to select it,open up the
Object Selection and pick it from there. By
selecting the ground you gain the ability to
apply a texture to it: for example, in theimage
below I’ve applied a grid image and
increased its reflectivity.

Sky
By default, when you render a scene there is
nothing in the background and everything appears
to be in the middle of a black and empty space.
You can change this in several ways: from the
Environment settings you can use any image as a
backdrop: for example, a picture of clouds.
However, if you animate the viewpoint, the
backdrop remains in exactly the same place and
spoils the effect.
The sky is different – it is an infinitely
large sphere which encompasses the scene. You can
switch it on and off in a similar way to the
ground (via the menu or floating object tool bar)
and also apply a texture or colour to it. The
sky-sphere may appear in the editing view but
this is only a representation of it, as it will
always appear in the distance when rendered. If
you try and use fog, you will find that your
images have a totally fog-coloured background,
irrespective of what settings are used for the
sky. This is not a bug: remember that the fog
continues into infinity, and so will always
eventually appear as an opaque object as you look
through it. |
