Utility functions common to fixture definitions.
generic-dimmmer
(generic-dimmmer)
A fixture definition where a single channel controls the power level of a socket to which an incandescent light source can be connected. If you are using a product such as the Chauvet DMX-4, its channels can be patched as four of these, or four generic-switch, or some combination.
generic-switch
(generic-switch)
A fixture definition where a single channel turns on or off the power at a socket to which an incandescent light source or other non-DMX-enabled equipment can be connected. If you are using a product such as the Chauvet DMX-4, its channels can be patched as four of these, or four generic-dimmer, or some combination.
index-color-wheel-hues
(index-color-wheel-hues fixture)
Associates color wheel hue maps with the fixture and all its heads, for easy lookup when assigning color at the end of a color effect chain.
index-functions
(index-functions fixture)
Associates function maps with the fixture and all its heads, for easy lookup by function-oriented effects.
printable
(printable fixture-or-fixture-list)
Strips a mapped fixture (or fixture list) of keys which make it a pain to print, such as the back links from the heads to the entire fixture, and the function maps.
visualizer-relevant
(visualizer-relevant fixtures-or-heads)
Returns all the fixtures or heads which might appear in the visualizer. If the fixture or head has an explicit :visualizer-visible boolean, that is honored, otherwise it is assumed that fixtures without heads are themselves relevant, while for fixtures with heads, only the heads are relevant.
