Pixel Fixtures with Control Channels by Mick Martin | Feb 27, 2012 | Knowledge Base

It is common for fixtures such as LED strips to contain a set of control channels followed by the RGB control channels for each pixel. To get the best out of these you should divide them in to 2 fixture groups – one for the control channels and another for the RGB pixels only.

Pulsar Chromazone

For example the Pulsar Chromazone contain 11 control channels for master level, programmed effects and other functions. The ShowCAD template file contains a template for these control channels. Add one of these for each Chromazone in a group of their own – call it Chromazone Controls.

To add the pixels, open the PixelArray template file and add an array. Any will do because you can change the shape and size of the array as you go through the wizard. Add these pixel in to there own group – call it Pixel.

Now when you are running effect Artist will treat these a one large block of pixels.

Pixel Arrays and Mapping view by Mick Martin | Feb 25, 2012 | Knowledge Base

Pixel arrays are, in general, RGB pixel arrange in rows and columns. They are used in building fascades, nightclub walls and stages. They can be used to display video content, effect or general lighting.

The pixel can be any order of RGB (i.e. BRG, GBR etc) and can also include amber and white. Artist has an algorythm that calculates the white value and replaces the RGB white level with the eqivalent level on white or amber. The proportion of amber to white is control by a global colour temperature control.

Pixel View

Pixel arrays are displayed on a special type of window. This is a graphics surface which can display videos, images and other effects. The pixel arrays are positioned on this surface where the pixel derives its colour.
