Mixing technique

Basics

Color mixing of lights are a bit different from normal color mixing. Since we can't add black as a color, black is just no light on. Some colors are hard to represent, this is in part dependent on what type of LED is used but also some other factors. Most of our lamps only have RGB, and can not produce "yellow" or "white" light very well.

Color fades

The dim function can be used to fade fixtures with RGB values between colors. Note that the colors will mix between colors during the fade resulting in a timeline like the picture below.

fade_normal

It is also possible to change color and lower the intensity at the same time. In this case the red color is only set to 20% of the blue colors intensity. It is also possible to accomplish this using the multi-layer technic below.

Multi-layer scripting

Layers can be used to create effects stacked on top of each other. The most common use is to run a script on the master layer and multiply that with a dimmer layer. One of the already existing scripts can run normally on the master layer and the dimmer layer can add in some randomness by flickering lights off and on. Great use for a spooky theme.

fade_on_off

The dimmer layer can also be used to "turn off" some lights in a specified area. An example that have been used is to turn of the roof pixels above the dance floor when the DJ lightning is running. And then on top of that have a third layer added to the data so that the DJ area can run roof patters even tho the rest is running another script.

Alpha-data layer scripting

If you have a base script loop, but want to a temporary jingle or similar, then placing the jingle on a seperate layer (jingle in the example) allows for the jingle to return the base script afterwards.

Example: take control of the washes, lamps, the microwaves, and box lights. After 30 seconds release the control.

local ownedFixtures = {washes, lamps, micro1, box};

-- Set the "starting state" of the fixtures
jingle:add(0, set(box, 255, 0, 255))
-- ETC. for the rest of the fixtures

jingle:add(100, take_control_of_fixture(ownedFixtures, 1000))

-- BUNCH OF CODE

jingle:add(30000, release_control_of_fixture(ownedFixtures, 1000))

take_control_of_fixture and release_control_of_fixture do not have to be in the same script. For instance, to make the DJ floor situation described in Multi-layer scripting, having a dj layer, taking control of the fixtures is done in a start script and releasing control in an end script.

Example: Multi-script layer control:

-- DJ_Start
dj:add(0, take_control_of_fixture(djFixtures, 1000))

-- DJ_Stop
dj:add(0, release_control_of_fixture(djFixtures, 1000))
