6.4 Fanning

Fanning allows you to assign a parameter across several fixtures, so that the parameter values are equally spaced. For example, if you have five fixtures all at 50% intensity, you can use fanning easily to assign intensities of 30, 40, 50, 60 and 70% across five fixtures. Note that in this example, the middle value of the five stays the same, and the end values change the most, while the other values change proportionally.

You can fan any values including parameters and timings. For example, you can use fanning with position: suppose that you have seven moving lights on an upstage position, all pointing downstage towards the audience. You could fan the Pan parameters so that the centre fixture still points downstage, and the others turn progressively out to stage left and right.

The fixture selection order is significant when fanning; see Selection Order. The value change when fanning is always relative to its current value; if there is no current value the parameter will fan from its default value.

[Tip]Tip

Choosing the initial, or ‘base’, value is important when fanning, as the parameter values cannot go below 0% or above 100%. Make sure that you leave enough of the value range for the value to fan into.

6.4.1 Using the Fan Key

To fan a parameter:

  1. 1 Thru 5 @ 30, Enter : select the fixtures and assign the intensities to 30%:

  2. Press and hold the Fan key, whilst slowly moving the I-Wheel. The fixtures at either end of the range take the values 10% and 50%, with those in between evenly spread across the intervening range:

6.4.2 In the Programmer Window

To fan a parameter:

  1. Select a range of cells, for example the intensity cells of Studio Colors 1 to 5.

  2. Set 10 Thru 50, Enter : The fixtures at either end of the range take the values 10% and 50%, with those in between evenly spread across the intervening range.

You can also fan backwards; continuing the above example:

  • Set 50 Thru 10 , Enter : Studio Color 1 has an intensity of 50% and Studio Color 5 an intensity of 10%.

You can also fan several columns at once, fanning both Pan and Tilt for example.

6.4.3 With the Command Line

To fan intensities from the command line:

  • 1 Thru 5 @ 10 Thru 50, Enter : The fixtures at either end of the range take the values 10% and 50%, with those in between evenly spread across the intervening range.

You can also fan backwards:

  • 1 Thru 5 @ 5 Thru 10, Enter : fixture 1 has an intensity of 50% and fixture 5 an intensity of 10%.

6.4.4 Fanning Options

By default, fanning adjusts parameter values proportionally from the centre of the fixture selection. You can have fanning work in other ways:

  • Fan Normal: As described above, the middle fixture remains unchanged, while the first and last fixtures' values change the most, in opposite directions. For example:

    Before fanning:

    30

    30

    30

    30

    30

    After fanning:

    10

    20

    30

    40

    50

  • Fan From Start: The first fixture in the selection order remains unchanged, while the last one's value changes the most. For example:

    Before fanning:

    30

    30

    30

    30

    30

    After fanning:

    30

    40

    50

    60

    70

  • Fan From End: The last fixture in the selection order remains unchanged, while the first one's value changes the most. For example:

    Before fanning:

    30

    30

    30

    30

    30

    After fanning:

    70

    60

    50

    40

    30

  • Fan To Centre: the middle fixture remains unchanged, while the first and last fixtures' values change the most, in the same direction. For example:

    Before fanning:

    30

    30

    30

    30

    30

    After fanning:

    50

    40

    30

    40

    50

You can set the fanning mode from the Fanning Toolbar:

All subsequent fans will follow the currently selected fanning mode, until the editor is cleared.

6.4.5 Multipart Fanning

With the command line, you can enter multipart fanning:

  • 1 Thru 9 @ 10 Thru 50 Thru 10 : The fixtures at either end of the range take the value of 10%, that in the middle 50%, and the others spread between:

    10

    20

    30

    40

    50

    40

    30

    20

    10

You can fan in as many parts as you want, separating values with the Thru key. Note that multipart fanning only works with the command line, not when editing values in the spreadsheet.

6.4.6 Fanning with Segments and Buddying

Segmenting and buddying allows you to control the way that parameters are fanned to make complex patterns.

  • Segmenting: Segmenting a fixture seletion is achieved by setting a segment size on the segments toolbar (represented as "segments of x"). Fanning is repeated for each segment. For example, segmenting twelve fixtures into "segments of three" will result in the fan pattern shown in the figure below:

    Fixtures Fanned in Segments of Three
    screenshot of Fixtures Fanned in Segments of Three
  • Buddying: The buddying number puts the fixtures into ‘gangs’ that all take the same value. For example, fanning a selection of twelve fixtures with a buddying value of three would result in fixtures 1 to 3 having the same parameter value, fixtures 4 to 6 having the same value, and so on:

    screenshot fragment of Fixtures Fanned with a Buddying of Three

You can combine segmenting and buddying to create complex patterns very simply. Segments and buddying are selected from the Segments Toolbar;: press Segments... on the Main Toolbar. The toolbar will remain open to allow you to combine Segments and Buddying; press Enter or click on the toolbar's Close button when you have made your selection.

Figure 6.15. The Segments Toolbar

The Segments Toolbar

The sgments toolbar displays the current segment and buddying sizenand has buttons to increase and decrease the segment size and the buddying. There are also shortcuts for common segment sizes and options for nexting by segment and buddying parts.

Note that segments and buddying are only used during fanning; segment and buddying information is not recorded into cues and palettes, but the resulting parameter values are recorded.

[Tip]Tip

By default the segment and buddying options are retained even after pressing the Clear key. To reset the segment and buddying options when Clear is pressed, enable the option in SetupPreferencesProgramming.
