Auf dem Holodeck gibt es über das Netzwerk steuerbares LED-Licht. Diese Seite soll grob die Funktionen dokumentieren. Für eine aktuelle Dokumentation siehe in der README.

LIGHT SETUP

The LED-light is divided into four sections. Two on each side. The front section is two thirds of the length, the back section is obviously one third.

Looking to the screen-side of the room:

• Section one is on the back on the left
• The folling sections are named clockwise

Some useful defaults

• warm white
• cold white
• nearly off
• really off
• hot!

USEAGE

The software exports a rudimentary web-based interface. The interface is divided into two sections:

• Section to set colors or presets
• Section to list and add/alter presets

Setting a color

A color is set using the following call:

http://holodeck.stratum0.net/holodeck/<section>/<colorCode>

Where:

<section> is all or a section number [1 .. 4]
<color> is a color-code

Color Codes are made up of a list of float values in the range of [0.0 .. 1.0]. Depending on the number of elements the color codes are iterpreted to be in different color spaces:

<float>: Is interpreted as brightness and creates a RGBW-mixed broad-spectrum white in the given brightness
<float>,<float>,<float>: Is interpreted as RGB-value. The value is transformed into the RGBW color space before outputting it. Thus even a 1.0,0.0,0.0 (red) will contain some white.
<float>,<float>,<float>,<float>: Is interpreted as RGBW-value. This value is directly outputted to the LEDs.
<float>,<float>,<float>,<float><float>,<float>,<float>,<float><float>,<float>,<float>,<float><float>,<float>,<float>,<float> (16 floats): This special form can be used on the section code all. It is interpreted as four RGBW-color codes for the four sections. Thus with this color code a new color for all sections can be set

Preset-types:

There are two types of presets:

• System-presets: These presets contain all RGB-colors defined with names in CSS. These presets can not be altered. But user-presets have a highter priority.
• User-presets: These presets can be set by the user. The list has a limited length.

Listing presets:

Presets can be listed using the following call:

http://holodeck.stratum0.net/preset 

Setting presets:

A preset can be created or altered using the following call:

http://holodeck.stratum0.net/preset/<name>/<color>

Using a preset:

A preset is set with the folowing call:

http://holodeck.stratum0.net/holodeck/<section>/<presetName>

If a preset with colors for all four sections is applied on a section other than all only the first RGBW-value will be used on the section.
