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.
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
Open one of these Links from inside the space to apply the new color.
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:
<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
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.
Presets can be listed using the following call:
A preset can be created or altered using the following call:
Using a preset:
A preset is set with the folowing call:
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.
