During the production, the initial idea of
the giant oh how it looks like were all designed and created by hand even
though it is a creation of a full 3D dimensional computer generation model,
even the storyboarding the presence of the giant should dismiss. It takes a lot
of talent and hard work because the illustrations will become the initial
blueprint reference for the 3D animation artist to with. Animators found it
really hard to animate the giant, a metal solid object in a smooth fluid
manner, so they have decided to use computer generated imagery. Joe Johnston
who had previously worked on the initial designs for the Star Wars Trilogy was
the choice for the job. Once the illustrations and design was completed, the
giant is now ready to be made. The 3D software chosen for the task to model the
giant was called Maya. It was used to sculpt the structure, which then could
later be rendered and painted with the 2D environment. They have used the same
traditional techniques inherited for the other characters. They have blended a
combination of Maya and Amino software packages which has the same colour
palettes that are being used on both 3D and 2D elements to produce the
‘uniform, perfectly blended feel.’
When modelling a 3D object in Maya (or any
other 3D packages, such as 3D Studio Max, Softimage, Cinema 4D, Light Wave and
Houdini these are the well-known main softwares) the object can be viewed as a
shaded wire frame. Using wireframe on shaded or x-ray helps the 3D animators
very well to gauge and measure where the object is laid out. The wire frame
displays all of the lines or edges, which are used to edit and model the
object. These lines are also very useful for the 2D animators. Even though the
model remains in the 3D basis, this adopts the features and appearance of the
3D model, though the model is rendered as a wire frame, lines can be used as a
colouring base layout for the 2D world. The template would appear the same to
the other unfilled outlines when it is loaded to 2D software. This is done to
make the map painting process easier and uniform. This is still very important
for the model giant to launch the same form of movement as the other characters
showed in the movie, and to fulfil the same sequence of motion. The same
techniques and structure layout has been simulated to animated the cartoon by
the technical team. Traditional 2D characters are animated by pose to pose, by
creating a different new pose on every other frame rather than on each frame
which doesn’t really work well on 3D animation which is unusual, this has been
also been adopter and used for the giant. Sometimes when the animation process
is completed, the technique will sometimes result on having to take out
alternate frames out from the scene, this process is very time consuming but it
is so much fast and easier than hand drawing all the lines and angles of the
complexly designed giant. It is very crucial during the making of any movie
when adjusting and sorting out the movement of the 2D and 3D elements, as this
could reveal most of the techniques used. Comparing 2D and 3D, a 2D
surroundings makes movement by dealing with flat areas and alternatively ‘3D
systems operate by manipulating volumes through genuine three dimensional movements.’
The style and movement and techniques were
used in the ‘Rugrats’ by Klasky Csupo. They have studied and applied its unique
characteristics throughout the years. They have used a similar 3D model of the
vehicle to the ‘Iron Giant.’ The chosen software for the job was Maya, this is
used for most of the complicated parts of the movie which makes work much more
easier. As for the vehicle, all the 3D were also linear render which makes look
like a blank colouring in book for the 2D animator to paint on top. ‘we don’t
fully render colour… we don’t set lighting or shading on the actual CGI
elements.’ The 2D software package that has been used for the cartoon was made
by USAnimation. It is very effective to use the program because of its power
and ease and also due to the fact that it can transit to 3D quite easily. The
philosophy of the ‘Rugrats’ shows importance on the aesthetic awareness of both
the 2D and 3D elements.
