Vertices in jit.gl.sketch to ILDA (.ild) format, how to get started?

Hi all,

I have a little question (which will most likely remain unanswered, but fingers crossed) about lasers and the ILDA format.
I have a laser which is currently connected to lasersoftware which allows me to draw images which are then sent to the laser using the ILDA standard.

No, I was wondering how I could get started on using jitter to generate points/lines and send that info to the laser in the correct format.
I’m sure there will not be a straight connection, but if anyone has a idea on how to get started, I’m very curious!

The computer is connected to the laser via USB, with a Minilumax light interface (www.lumax.de).

There are some documents on the ILDA standard

Hi Brecht,

Sorry to say this but i have no idea about this however these guys managed to have a lidar in max and even built an external for it.

It is unclear to me what format their laser used but it’s worth the try. I presume there’s a source to download too. (might make it easier to decypher)

Hope it helps and good luck,
FRid

Hey FRid. This is something different though, lidar and ilda are different things. The sick scanner used in this uses a laser to scan the area and returns the distance to objects (which could now be done with e.g. the kinect). I know the guy who made this and my brother, who works at V2, uses it in his installation Probe. It’s a cool device though, this installation also makes use of it (and the max external): Run Motherfucker Run.

The thing I want to do is send data to a laser in order to draw points and lines on the fly instead of having to work with pre-made figures which are triggered through midi or DMX.
There’s a .DLL, drivers and and API on the lumax site (unfortunately not for os x), so I’m guessing the way to go will be to program something in C, using OSC to send data from Max…

My C skills are way below par, so it’s going to be a long adventure…

“The thing I want to do is send data to a laser in order to draw points and lines on the fly”

Aha, i get it, it’s the other way around. I guess that’s really pioneering. Cool idea though. Maybe send an email to lumax explaining you need the source :) otherwise you’re in for an adventure.

Did find this though maybe it’ll help

Yeah, that’s a great video, stumbled upon it recently as well. His software is open source, so maybe it’s something to take a look at.
His trick is to use audio equipment to control the galvo’s, but that would mean I need to build a laser myself or hack the one I have available.
I’m guessing I’ll need to look for some collaborators to do that, since electronics is really something I know nothing about.

Hello Brecht, did you achieve this project. We are currently on a project who involved drawings with laser too. Could you share informations about that ? Thx. F./
