I can't figure out how to say that if one video is on, the others on that same layer should be off. 

 In your patch, you are testing the incoming value by limiting the range that passes through with a Pass value Actor. This is a good approach if you are getting different ranges from each sensor.
Next, you have a Trigger Value actor which sends a number. You could use this value to test which stream is active (rather than setting the Movie Number).
You might do this with Comparator actors, or send the value to a Selector actor as suggested above... there are many options.
What you might want to control is the Visible input of the Movie Player (if you would like the video to stop and restart each time), or the Intensity of the Projectors (if you would like them to play continually). Using a Selector as suggested is another option where the movies could continue to play and you would simply switch which movie is routed to a single projector (remove the others).

*** Isadora will layer/stack the videos added to a scene in order (left to right, top to bottom) when they have the same layer number. The layer numbers will allow you to break out of this layering if needed. The layering also uses the blend mode selected in the projector, so you can create some complex composites using nothing more than this technique.

@aaresty

Isadora will run natively on M1 machines.
Specific Add-Ons (eg: OpenNi Tracker) will only work under Rosetta 2.
Please take a look at the System requirements to get a complete understanding of which versions are supported on which operating systems.

@juriaan Amazing!:)

Once upon a time.....when QuickTime was still the bomb, you could embed text, midi, multichannel audio and timecode to a single QuickTime movie. From QuickTime 5 this was ditched and up until now there has never been a file format that was that close to all-in-one format that could be made with a broad range of editors. You could edit audio and video and midi in Protools or another DAW, and export the whole thing to one QT file. In the QT player you could add different audio outputs and midi out to a external midi I/O or patch internal. Did many show like that always rock solid. I discussed the last 15 years with Mark several time this approach, but due to constant change in Quicktime it was not possible this way anymore.

Zap, many years later I had to do a large showontrol setup for a show in Rotterdam, but was not able to use timecode, since all tracks that were played there were coming from a DJ setup and give him the freedom to mix it like they always do, so also change in pitch. So in that time we used DVJ's and I added in the bottom of the video several stripes with optical markers for pyro, laser, lights and commands for boats. So the markers were setup up as a binary coded stripe and you could add numbers for playlists and everything. The video was played out by the DVJ's, and we got rid of the info stripe at the bottom before we ended out to all projectors. The software in that time (I'm talking about 13 years ago) was also Isadora and I used it to decode the optical markers. I did not use colors but used "placement" tabs,  black for zero's and white for ones and sended out the corresponding midi triggers to all equipment. Was a hell of a job back then and can't remember what actors I used to measure the optical triggers, there was a reason why I used black and white instead of colours. Any how, the whole setup of the show including the setup of all triggers was done in Final Cut Pro. 

So when you use timecode, this works great with a non-pitched video, but when using a bunch of starts and stops, variable pitch, optical markers are a great tool. in Isadora you could make a tool that generates a optical marker with a certain midi pitch in to make the setup proces quicker instead of hanging 6 A4 on your wall to doublecheck if that one optical marker is the right one hahaha

Is there any ZoomOSC demo config for testing?

The file itself is already configured to work with ZoomOSC (there's also a comment in the setup section with instructions on how to setup ZoomOSC's settings to talk to Isadora). You'd need a license though in order to get the /zoom/list to return a list to you over OSC on the address /zoomosc/user/list.

@dusx said:

It would be easiest with actual data coming in. 

 You'd need to hop into a call with tons of users (or bots) to get usable data to come in.

@kerrodb

You may benefit from the Troikatronix Guru session on this topic.

@woland Thank you !

(Make sure your students know that the forum is always open for any questions they may have) Yes of course !!

Best,

Hi there Emre!

Welcome to the Isadora community forum, glad to have you here.

Isadora doesn't offer any native functions that are specifically intended to streamline the process of projecting onto a sphere. We do however have the tool called "IzzyMap" and the Stage Setup (Edge blend tool) that will allow you to get quite far with what you are trying to accomplish.

If you don't have access to programs like Vectorworks or CAD to pre-visualize the throws of the projectors (based on the make, model, and lenses) onto the sphere you will however have a lot of trial and error to do to figure out where the projectors need to be hung / etc.

It seems that you are just starting with Isadora. So I would suggest the following;

Isadora is paid software, but we offer a demo mode that allows you use to use all the features of the program. The only limitation that we have is that you can't save without a license, you can however rent a license for as little as $10/week.Watch the Guru session that Mark (Creator of Isadora / Media artist) did on the subject of Projection mapping Ask the community! If you ever become stuck or need a hand post a topic on our forum and members of the community will give you a hand.You can also send us a Technical support ticket ;)

Have fun!

Just for the people that find this thread through search / Google.

We just published the M1 version of Firmata to our Add-ons section

@oscar

No, it's not currently possible.

But I made this feature request some time ago:

https://community.troikatronix...

Perhaps time to bump it up :-)

In the meantime, I have found that setting the movie player to view timecode, and using the timecode comparator actor (IME set to ge (equal than or greater to)) works well.

Yes, it's a long way 'round.

HTH

Mark (not that one)

Thanks @Woland for explaining the differences illustrated in your attached video

I should have been more specific with my question. If input a constant stream of changing numeric values into a Smoother and a Multi Blocker with the Smoother's smooth setting set to 0, the output of both will be the same as i increase/decrease their corresponding frequency/time inputs - right?

@dcarmich said:

how can I have a trigger automatically sent on startup to connect to the dLive system when the patch is opened?

The Enter Scene Trigger actor can be used to trigger things upon entering a Scene, so put one in the first Scene connected to whatever it is you want to trigger immediately when the file is opened.

@dusx when I got the results above I literally just had a video in actor hooked up to a projector and the RTMP actor, and the whole thing choked itself down to about 12fps.

I don't remember what the project resolution was, so I'll do some optimisation experiments over the weekend.

Thanks for your help

@the_navigator

Hi.

Sound very similar to a project I was part of a while ago in Helsinki called Reveal in 2012/13 [https://vjskulpture.wordpress....]

The touching part is also possible! Drop me a DM!

Dear all,
Oh my, you are the best:) Thank you so much! I will try this out:)
All the best
Eva

@woland

first of all, thank you very much. 

I applied the 3rd example and it worked. I had to tweak a few values but it works perfectly.

The project, which is part of my practice-based PhD, is an art installation.

I walked from England to Italy last summer, and I want the visitor to the installation to experience part of my walk.

When they enter the space, they are presented with a walking machine (along with other things). 

When they start walking the video, recorded with a 360 camera, of my walk is activated and when they stop the video carries on without showing, and you can just hear the sound. 

It is a way for me to create a sort of reward, where if they walk they can see what is happening.

I was really stressing out, and you guys here are so knowledgeable and really helped. 

And if you are ok, I will mention all of you in this topic and the troikatronix community, in the acknowledgement of my final thesis.

Really thank you!!!!!!!!!!!!!!

@kellyruokay

We haven't seen a ticket from you. Did this get sorted out?

Best wishes,

Woland

@woland Thank you, I though MA wasn't taking Midi show control, I'll try that way!

@kathmandale I hear what you are saying but for now the only thing that I'm trying to solve for right now is the live streaming element of the project. So if the most reliable way to sync the audio over multiple camera feeds is to run our sound through one of the those cams mic inputs... that's what I'm going to do. In reality at the venues we're going to using we probably aren't even going to need to amplify the cast in the theatre space itself.

This thread is really only about trying to that syncing problem sorted, and primarily its about getting the right hardware for the job. I'm going to do some experiments with a PCI video capture card with 4 inputs next week, which should at least remove USB bandwidth issues from the equation and I'll come back with the results of my testing so there's a resource  on the latency of various devices available for anyone who needs it.

@antcaramelo

Hi,

I can chime in to this as I use a USB microscope with Isadora. I have had no problem with the camera being recognised by the Live Capture Settings...

Best Wishes
