5. Shapes
This chapter contains: Selecting a shape; changing the size and speed
of a shape; spreading a shape across multiple fixtures; editing shapes
which are running.
The Pearl, in common with other Avolites consoles, has a shape
generator (sometimes known as an Effects Generator on other
consoles). This allows you to quickly create exciting light shows using
lots of movement and changes, with the minimum of programming.
A shape is simply a sequence of
values which can be applied to
any attribute of a fixture. A
circle shape, for example,
applied to the pan and tilt
attributes, would cause the
fixture to move its beam around
in a circular pattern. You can
set the centre point of the
circle, the size of the circle and
the speed of the circle
movement.
In addition to position shapes, there are a large number of other
shapes available in the Pearl. The shapes are defined for a particular
attribute such as colour, dimmer, focus and so on. Some shapes will
not work with some fixtures; focus shapes, for example, can produce
nice “focus pull” effects on fixtures which have DMX focusing, but will
do nothing on fixtures which don’t have focusing.
When you use a shape with more
than one fixture, you can choose
to either apply the shape
identically to all the fixtures, or
offset them so that the shape runs
along the fixtures creating “wave”
or “ballyhoo” type effects. This is
called the Phase of the shape.

5.1.1 Creating a shape
To create a shape you simply pick
it from a list on the softkeys.
Shapes are listed using the
IPCGBES attribute groups, so you
can pick from a list of Dimmer
shapes, or a list of Pan/Tilt
shapes, or Colour shapes, and so on. You can also pick from a list of All
Shapes.
When you choose a shape, it will be applied to all selected fixtures.
1> Select the fixtures the shape is to be applied to.
2> At the main menu press C [Shape Generator].
