blender dmx visualization

[Petr Vanek]

FYI, while looking for artnet python library (if i wanted to simplify and not to use the full ola), i found this interesting topic:

I’ve always wondered about doing that, but with my very very limited
knowledge of blender, I’ve never bothered.

Recently, if you’re just desperate for a decent free visualizer,
Capture released a free Student edition! It’s limited to 2 universe of
input (from Art-Net, etc.) and has a limited fixture library. However,
it’s perfect for when you’re playing around with OLA or other lighting
software and need an easy way to see what you’re doing.

What's required to update the OLA python client libraries to Python3?
There is a Python3 version of protobuf here:

https://github.com/openx/python3-protobuf

It looks like the changes are going into the main release.

Also olad supports OSC now, so you could setup olad to receive ArtNet
and send OSC messages directly to blender without having to use
Python.

Thanks you for pointing me to the new OLA release and the OSC plugin. Thats exactly what I need.
Tried it yesterday evening with blender. It works.

I connected the QLightcontroller, OLA with the OLA OSC Plugin and Blender to run a simple Lighting Visulation Test.
It works quite well so far. Thinking about to write a separate Blender addon for that.

Here's a screencast:

This is dmx --> blender..


How about blender --> Dmx.


If we could define a bunch of "things" in blender and then animate through them, could it be possible to build a cool kind of media engine for mapping to LEDS?

Very cool. I always like seeing what other people do with the software.

blender --> DMX is a nice idea-
whats your idea behind?
i mean how do you want to generate the dmx values?
what is the source?
in blender you can animate (nearly) all things - do you think of some result video to dmx matrix mapping?
or more something like - if a 'cube' is rotated in direction x map this rotation to dmx channel y ?
with the last idea you could do something like:
-> some Input to modifie objects in blender
-> blender generates some video output
-> and you can use interactions to get them back to the real world...
hm nice ideas...

Yes.. sort of,i'm thinking that you could build an animation of your real work object, and then map from there.
