Artist Help:Example Pixel Arrays

The Plasa Workspace is an example of using Pixel Array fixtures on the effect canvas. This workspace was designed and used on the Pulsar Light of Cambridge stand at Plasa 2006. The lighting was entirely Pulsar's LED fixtures including ChromaStrips.

The workspace contains a fixture group for the large outer triangle and a separate fixture group from the smaller inner triangle which illuminate the triangular screen.

When activating cues it is best to view the Fixture group in the client area and open the Cue navigator. You can double-click on a cue icon in the navigator in order to activate and view the effect in the Fixture view.

The Fixtures

The first thing to notice about the fixture setup is that each edge of the triangles was regarded as a fixture even though it is made of between 2 and 3 ChromaStrips.

The ChromaStrips are powered by a ChromaZone which is a 48 channel LED power supply. The ChromaZone has many built in function channels apart from just the RGB LED channels. The control channels are defined by a separate group of fixtures. These are the Large Triangle Control and the Inner Triangle Control groups.

See Creating Arrays for details on how the fixture were laid out on the effect canvas.

The Scenes

There are only a few scenes in this workspace. These are used as sub-scenes to be accessed by cues.

Outer Triangle

Edge chase	a six step sequence in white
Spoke chase	a three step double spoke sequence
Static chase	a three step sequence of static colour looks

Inner Triangle

Scene 1	3 step, 2 colour, double diamond sequence
Circle chase	6 step sequence of inner edge
Spoke chase	6 step sequence of inner spoke
Scene 4	random firing of each triangle in multiple colours
Cascade out	cascade of outer ring of triangles
Cascade in	cascade of inner ring of triangles

The Cues

1 - Outer Triangle - static

This list contains static looks for the larger outer triangles. Each of these is assigned a one second fade time

2 - Outer Triangle - active 1

This list contains active scenes and effect and each has a one second fade time. All the canvas effect in list are simple single layer.

Caption text

3 - Outer Triangle - active 2

This contains multi-layer effects and have a one second fade time.

Caption text

Yellow/Cyan linear	this cue uses 2 linear effect in cyan and yellow with opposite rotation

The fly	this uses 2 Polygon effects with balck as the foreground colour and sweeping background colour.
Baby Snakes	this is a single layer polygon effect
Chroma Search	this uses 2 radial effects in counter-rotation.

4 - Inner Triangle - static

This list contains static looks for the Inner triangles. Each of these is assigned a one second fade time. These simple cues except for Static Blue, Static Green and Static Red which use a Ellipse Blend effect.

5 - Inner Triangle - active 1

This list contains active effects for the Inner triangles. Each has a one second fade time.
