Modules for intelligent DMXequipment

For working with intelligent lighting equipment it is useful to have some special modules.

  • driver-nodes for DMXinterfaces
naming proposal: DMX (Devices manufacturer)
example: DMX (Devices DMX4all)


  • DMXfixtures

These Modules combine all Parameters of a MovingLight to a spread which can be sent directly to DMXinterfaces or to DMXsimulations.

naming proposal: manufacturermodell (DMXfixture)__
MartinMAC600 (DMXfixture)__
  • DMXsimulation

These modules should simulate a MovingLight in a 3D-rendering environment.
These Modules should have a spreadable transform input for placing them in the 3Denvironment
These Modules should have a spread input which can be fed directly from the corresponding DMXfixture-module.

naming proposal: manufacturermodell (DMXsimulation)__
example: MartinMAC600 (DMXsimulation)__


  • DMXspreads

These modules should generate useful spreads e.g. for chasing etc.

naming proposal: modulename (DMXspreads)__
Audiochaser (DMXspreads)__
  • PanTilt

These modules should generate special which are especially useful for controling the head-(or mirror) movement of several MovingLights

naming proposal: modulename (PanTilt)__
example: SpiralCircles (PanTilt)__


  • GenericDMX

Everything else for generic DMX usage

naming proposal: nodename (DMX)__
16bit (DMXValue Join) 16bit (DMXValue Split)

The advantage is that all "DMX"-Modules appear near by near in the 'categorized nodelist'.

You have several Categories (DMXfixture, DMXsimulation and DMX for generic Helpers) to choose from.


DMXfixtures Modules

should combine all functions of a DMX Fixture to a spread that can be directly sent to a DMXinterface.

Let's have a look at a typical module for a moving light:
the Pocketscan from GLP is a very cheap movinglight (less than 300 Euro !) controlled via DMX.
It uses 7 DMXchannels and has as a special gimmick a laser pointer inside.

With that Resample/Swapdim/count of devices thing inside the pocketscan module seen above you may control parameters for all units simultaneous by simply changing a value or you may benefit from vvvv's technology called Spreads.
Put a Spread with a whatever slicecount onto any of the Inputpins of that pocketscan module - that Resample (Spreads) node in Repeat Mode prevents any collapsing.

A simple Cons (Spreads) combines that spreads together and feeds one of vvvv's various DMXnodes.

Note that there are other movinglights with a little more features. The Vari-Lite VL3000 Spot e.g. uses 28 DMXchannels and costs a little less than 10.000 Euros.
See that module below?
29 Inlets and 140 nodes inside...

DMXsimulation Modules

DMX Fixture Simulation Modules should have a DMXspread Input and a Layer Output

Pan/Tilt Movement Modules

DMX General Purpose Modules

16bit split
16bit join
AsValue (DMX)
AsDMX (Value)
StartAdress (DMX Boolean)

joreg: @schlonzo re "SDSL support" did you see the Shader wizard? or do you mean something different?
