Lesson 9 Tut3

DMXControl 3 lessons

Overview

The previous lession introduced into simple cues. In this lesson we explain some more sophisticated features of scenes, e.g. the fanning feature. With fanning you can create impressive effects with groups of lamps, e.g. rainbow effects or waves.

Lecture 9: Fanning, chasers and other effects

DMXControl 3 extends the scope of scenes in that way that dynamic effects can be included and that you can apply certain algorithms for the attributes (DMX values) of included devices resp. groups. This allows you to create highly complex scene with few mouse clicks. Don't believe it? Let's demonstrate how it works!

Fanning

The first mechanism is fanning.

Fanning means from technical point of view to split a value oder domain to a group of devices. We distinguish between linear and alternate fanning, see following tables explaining the syntax element.

linear fanning

Syntax	Example	Description
>	50 > 100	linear interpolation
<>	50 <> 100	linear interpolation: marginal devices: 100, central devices 50
><	50 >< 100	contrary: marginal devices: 50, central devices 100

alternate fanning

Syntax	Example	Description
#	50 # 100	alternate values 100/50/100/50 ...
# #	100 # 50 # 0	alternate values 100/50/0/100/50/0 ...

How does it work?

Lets assume we want to have a cue where the 8 RGB Pars have to be faded from red in the middle to blue at the ends.

How many actions are needed for programming? 8? 16? 32? The answer is: three. We will apply linear fanning by "><" where we separate the marginal devices from central devices. The actions:

• select the group "RGB pars"
• Go to property grid panel and type in for red color "0<>255"
• type for blue color "255<>0"

Here is the result in property grid:

Let's make another excercise with alternate fanning. The task is switching on each second lamp (i.e. setting dimmer to 100%).

There is a simple solution: Insert "0#100" into the dimmer value text field.

Effects and attachables

With fanning you can create static cues. The attachables panels provides some effects that can be used for dynamic changes within a cue.

Remember: Attachables will be summed to the values that are manually adjusted. (If the device has a dimmer of 30% adjusted und you add a sinus with amplitude of 20%, the brightness minimum value will be 30%, the maximum value 50%) 

Let's have an example: You want to have a blinking effects with all frontlight lamps with lowest brightness for the central devices.

Here we will use the "attachable" pannel showing some effects such as "Sinus", Trapezoid", "Sawtooth" etc. Per drag&drop we can load the Sinus effect to the dimmer attribute within property grid.

Following settings are nessecary (the amplitude will varybetween 30 and 100 %):

Try it!

Hint: Press the Del key to remove the effect from the attribute.

Attribut	Example	Description
Amplitude	50 > 100	value interval for selected attribute; can be set to negative value too
Offset	[0..100]	offset between group elements
Phase	[0..1]	?
Frequency	[0..1]	cycle speed

Tipp: By fanning the offset you get interesting chasers.

In order to illustrate the power of this concept we have listed following use cases for you:

Use case	Visual effect description	Amplitude	Offset	Phase	Frequency
Jump Effect: Dimmer should slowly fade to 0 and will jump to full value	set dimmer to 100, drag sawtooth effect to dimmer attribute	-100

to be added (by beta testers)

• add some additional use cases

Excercise

• Try to apply fanning to moving lights. That rocks! ;)
