Booleans (cutting and molding tools)
If you're a programmer, you think of Booleans as either a true or false value. This is
a completely different Boolean campared to an operation in 3D modeling. Simply
put, a Boolean is a relationship between one object and another. There are four basic
Boolean operations that you will find in any 3D modeling software. These are
add
,
subtract
,
union
, and
difference
. First, let's create another set of geometry to Boolean
with our salt shaker. Duplicate your octagon (in Maya, simply use
Ctrl
+
D
). Scale the
octagon so it's smaller in its depth and width but taller than our original geometry,
and move it up slightly, as shown in following screenshot:
