What you did is probably how I would do it.

Could you please send in a ticket using the link in my signature with a screen recording where you show Stage Setup and more clearly narrate and show the roadblock you're hitting within the keystoning? I get the general idea, but I want to understand more precisely so that I can accurately log this as a feature request.

Hello I'm trying to find a way to project my canvas and particle based code from p5.js via Isadora.
From what I read in the forum it's not possible to project with Isadora's javascript actor. Does anybody happen to know another way to showcase/project the code? Thanks in advance for any further help :)

Thanks so much for your suggestion — I’ll definitely give it a try. At the moment, I need to keep the system as simple as possible. It’s an interactive installation using Arduino with heartbeat sensor detection. I use GLSL to overlay waveforms onto a large selection of movie files, which are then re-captured and reloaded into the installation. The system must auto-load and configure itself each morning. The audio has its own separate routine: by counting the number of re-captured videos, I’m able to trigger a beat sound file once a saved waveform overlay clip has been recalled.

I truly appreciate your help — I’d definitely like to explore using Pythoner in a future version of the patch!

By default Projector actors are not connected to each other at all. If you want to have the same mapping in all of them but be able to adjust different inputs on them, you should wrap a Projector actor in a User Actor and add User Inputs connected to the inputs on the Projector actor that you want to be individual to specific Scenes.

See this video tutorial about Isadora User Actors for more details.

I eventually want to stream 4k, but this is more to do with the bandwidth of the various platforms rather than any Izzy issues.

You should chat with the folks at Office Hours Global. They're always pushing the limits of what's possible when it comes to broadcast and streaming. I've been hanging out there for years and they're all super knowledgable and friendly.

Hi everyone,

I’m looking for a reliable „mobile“ internet solution to stream live video and audio via IzzyCast (using Isadora) for a hybrid dance performance between Cologne (DE) and Oulu (FI).

The Cologne location has no fixed internet, so I need something mobile (5G/LTE), with low latency and solid stability.

What do you use for mobile streaming with Isadora?

Thanks!

@dusx

I can confirm that the method suggested by @dusx works for the ‘3D model particles’ actor. The technique is used in the two demonstration patches offered in this thread to assign red, yellow and blue textures. The ‘texture’ input accepts video and using alpha channel transparency you can apply numerous animations to simulate a ‘morphing’ appearance of an alphabet on a simple unchanging 3d geometry 3ds file.

Best wishes

Also I have a free 1-hour Isadora Lab in this Zoom Call every Thursday from 7pm to 8pm CET.

Everyone is always welcome, regardless of level of Isadora experience, and what I cover is determined by who shows up and what they want me to dive into.

If you drop by with your patch or questions some Thursday I'd be happy to help you out.

Thank you DusX,

You are correct. I now have the 'shapes' actor working properly. 

However, I am using a GLSL Shader to create the video I want to use as a transparent image. And I think you've also helped me there as well, as the shader does not have a transparent background. I will consult ChatGPT to see if it can help me add one.

@reload2024 Yup, managing EDID is fun. The high-end media servers (disguise, Pixera, GreenHippo) all manage these with additional hardware and software (one company uses a mini Raspberry Pi hidden away in their cases just to manage EDID). 

It sounds like you need/should keep the Mosaic on then. I would use the tools within Isadora to achieve what you need. Might be worth making a template to map out the outputs - if that makes sense? All you are doing really is managing the pixels and where they go. Keep us posted, happy to help if/when I can. 

That works perfectly!

I guess I was clicking on the quad instead of its checkbox, trying to add an OSC control.

Thanks, @jandraka

It's not in the Control Panel, but Isadora also has a Cue Sheet function:

A collection of resources for learning about Control Panels in Isadora:

Our Isadora 101 Control Panel Youtube Tutorial is the best place to start.Here's a much longer, in-depth recorded Control Panel-focused livestream by Mark Coniglio, the creator of Isadora.The Isadora 4 Manual (current version at the time of writing this is from October 2024) covers the Control Panel in various places:Basic explanation of Control Panels on pages 184-198 (this needs to be updated but is still good information).Set Control Focus Actor is covered on page 718.Show-Hide Control actor is covered on pages 725-726Here's a Show-Hide Control actor example file.You can also dissect the complex logic that makes the IzzyCast Basic Template Files' Control Panel act like a full-on application with different views, settings panels, previews, etc.Controls Reference Section on pages 829-887YouTube Mini TutorialsSearching for Actors and Controls Control IDsShow Value of Linked PropertiesShowing and Hiding the Control PanelCopying Controls between Control PanelsScene Select ControlList Selector Control and the accompanying example fileFiles to look at:The general Isadora Examples files has different Scenes with various Control Panels.My simple show file exampleMy global projection mapping fileMy Scene-based cue text example fileMy Scaling Isadora Example FileMy Color Tracking Isadora Example FilesMy Simple Q Control ExampleMy MIDI Show Control Scene-Navigation & Cueing SystemMy CONTROLS Scene and Set/Get Global Values (HSL Adjust) ExampleMany of my example files on the TroikaTronix Add-Ons Page have Control Panels.Many of the official TroikaTronix example files on the TroikaTronix Add-Ons Page have Control Panels.Lastly, if you want some live help, I personally hold a free 1-hour Isadora Lab via the professional AV community Office Hours Global. The lab is open to anyone (not just AV professionals) and is held via Zoom every Thursday from 7pm-8pm CET (since I'm in Berlin, Germany). Sometimes I help people with projects, sometimes I teach people more about Isadora, and sometimes I teach people about Isadora from scratch. What I do during any given lab is determined by who shows up and what they'd like and I enjoy teaching Isadora to people and helping them with projects regardless of their level of experience with Isadora.

Here's an article on how to use the Set and Get Global Values actors: https://support.troikatronix.com/support/solutions/articles/13000014936-using-the-global-value-actors

Additionally, if you take a look at the Isadora 4 Manual, you'll find:

The Get Global Values actor on pages 501-502The Set Global Values actor on pages 719-720

As you're new to Isadora, I'd also recommend checking out our Isadora Mini-Tutorials playlist on the TroikaTronix YouTube Channel. There you can learn some helpful basic tips, but also tricks and best practices that that might take you a while to figure out otherwise.

<p>@undergroult said:</p> <blockquote>i don't understand which kind of channel input he had use</blockquote> <p> I am pretty sure, what he would have done is used a Sound Frequency Bands or Sound Frequency Watcher actor/s. In live capture settings (input/live capture settings) in Isadora you need to select a Sound Input device, ensure 'Sound Frequency Analysis' is checked, and Start Live Capture. That will provide the audio source to the Sound Frequency Bands or Sound Frequency Watcher actor/s in your scene. These actors allow you to convert audio frequency values into numeric outputs in Isadora. These numeric outputs can then be fed to your GLSL shader actor to control inputs, making the GLSL audio reactive.</p>

 Something like that probably.... I think I managed to publish an input in the code. This was 5 years ago... can't fully remember.
