to represent each of the major structures in your scene. For now, do not worry about
any background that might be present. Instead, focus on the illusion object alone. In
the Escape-proof prison , this is the main prison building alone. The waterfalls and
foreground wall are both drawn normally. Refer to your object breakdown drawing
when you do this, so that objects that should be separate remain separate. By mov-
ing them in the camera view, you should be able to make them align as if they are
joined as in the illusion.
After your objects align, make an effort to bring the pieces as close together as
possible. This adds to the diffi culty of the project, but it also makes for a more
believable scene when the camera is animated.
Hint: Try and come up with an original solution to the illusion by creating a
secondary illusion within it.

6.5.7 Build Elements

After blocking out your scene, you are ready to build the fi nal scene elements.
Double-check to be sure that your blocked out elements match the drawing per-
fectly. Any discrepancies at this stage are easily fi xed, but after you have started
building fi nal geometry, modifi cations can be very time-consuming.
The drawings provided in this topic contain several types of elements. They are:

• Illusion object. These are built of straight parallel or perpendicular lines and arcs
or circles. This is to keep the shapes simple for beginning artists.
• Characters. The characters are present for scale and for more advanced students
who may want to build them. They are an optional part of this assignment.
• Background. The backgrounds are purposely complex to emphasize the need
for an optimized solution that does not require the modeling of every tiny
