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
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
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
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.
A further category of shapes is the Block Shape. This type of shape
A further category of shapes is the Block Shape. This type of shape
blocks out other shapes, preventing them from running. For example,
if some fixtures are running a Circle shape, and then a playback is
fired which has a Block Pan/Tilt shape on some of the fixtures, those
fixtures will stop running the circle shape. This can be very useful to
modify playbacks at showtime when used with the playback priority
feature (see section 6.7.5 on page 76).
When you use a shape with more than one fixture, you can choose to
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.
