Hi Donald,

If I got you right, I guess that what you're looking for is the "mapping" IZZYMAP.

To do what you want double click on the projector and Izzymap will open. You'll have the input and the output, you can switch between input/output and split view, by clicking on the words "input/output or split" that are centred on top of the window.

So once you're in the output, you'll see a rectangle delimiting your projection. Midway on the lower is a circle with 4 arrows, click on it and move it towards the centre of the rectangle. This will keep the same ratio, but make the output smaller. But that's what the zoom parameter of the projector actor would do.

If you want to keep the size of the projection the same, but zoom in the image. Then do exactluy the same, but do it on the input window instead of the output window.

Not sure if you were looking for this, but I hope it helps.

Hello. I was in the middle of a workshop today and I wanted to increase the size of my media bin thumbnails to assist in deleting multiples, but Izzy wasn't happy.

Changing the thumbnail res in the Settings menu opens two instances of the dialogue about regenerating, and one of these refuses to go away, so I can't close the Settings menu.

I needed to quit Izzy to get rid of the dialogue.

I'm on Intel Mac with the latest Izzy. Anybody else having this issue?

Hi G - I use Value Delay Line with a Comparator.

@woland thanx!

Hi everyone,

I recently replaced a Christie lamp projector with a laser projector and kept the same Medialon integration. Previously, I used the TCP command HIS+LMP6 to retrieve and display lamp hours on the user interface. This worked perfectly with the lamp-based unit.

However, with the new laser projector, this command no longer functions and returns an error. I suspect that the laser model uses a different parameter for tracking usage hours, but I haven't found the correct command yet.

Has anyone dealt with this issue before or know the correct TCP command to retrieve laser hours or operating hours from Christie laser projectors?

Any help would be greatly appreciated.

If you post the original file I can take a look, but without that or more information there's not much I can do

Popopoooo, thank you JF and DusX !

It was super helpfull :) I have now the feddback that I needed, lessssgo to perform now !

Dear All,

thank you for your answers !

Sadly, I have no skills for any of these solutions, and most of all, it's for live performance so it's already a mess to hold computer, wifi webcam and play in front of so we decided to skip this scene.

Btw thank you anyway !

@woland Wow it seems to work fantastic! Thanks for your help I'll need to upgrade to Izzy 4

Cheers, David

@dbini You could also play with the parameters bleow smoothing about area surface and same area max distance. Bit it depends how what you are tracking moves

@woland

What happens is when I quit Isadora, the file closes, all windows disappear, but Isadora remains open, lurking in the background. Attempts to quit from the Isadora dropdown do nothing and I need to Force Quit. I suspect it may have something to do with either the OpenNI Tracker or Screen Capture actors. Recently I've been working on a new patch that doesn't include either of these actors and Isadora is quitting perfectly.

@dusx

I've tried deleting the media on prompt when closing the file, or using the Delete Captured Media button in the Output dropdown.

So sorry for the late reply - other projects were prioritized, now I finally have the time to look back into this. My IT department has essentially abandoned me, so I'm on my own.

I'm still a bit confused, apologies that I'm not following. You're saying I *don't* need to convert the video to HAP? Isadora does that automatically?

Just to try your suggestion, I did convert it to the HAP codec manually in media encoder to try it out, but when testing in Isadora there's no difference between the original video and the new HAP video.

It seems that the spikes are better, I think because my computer finally transitioned to using the NVIDIA graphics card after I forced the setting. Once I start "show stages" the little NVIDIA manager pops up to tell me it switched over, which didn't happen previously. 

I'm no longer spiking at 180-200% load, but I am at a consistent 80% load. It spikes up to to the higher end of 80 when videos restart on the loop. It spikes over 100% when I use any watchers or generators. The same file on my personal computer doesn't go above 40%. It's not sputtering and lagging like it did before, but the spike is still concerning to me, especially because I'm doing relatively simple stuff. No depth cameras, external accessories, or generative content yet. This is all with the projector connected.

If it's not the HAP codec, and it's not the GPU, and it's not the security permissions, what else could it be? Agh!

Thank you so much!!

 Known about it for a while - it's used in some very big and beautiful installations. Seems a nice product. I don't have any other information on it really. Let me know if you use it. FYI - it does have a demo/trail.

@woland

thanks for this generous advice. I have just started using ChatGPT a little for making Shaders, so I will expand those experiments a bit further for this project.

We are very happy to announce that Isadora will be powering the Venice Architecture Biennale from May 10th until November.

Isadora Latin Network in partnership with mexican visual artist Héctor Cruz, is responsible for the design of the immersive video projection device that accompanies the installation.

The piece "SIESTARIO" (by Argentine architects Marco Zampieron and Juan Manuel Pachue) is the winning project for the Argentine Pavilion at the Venice Biennale. 

We're already working on the Biennial pavilion. More news coming soon.

If you're in Venice, don't miss the Biennale... !

Big hug,

Maxi Wille-RIL

The input on the Broadcaster is mutable, meaning it will change to match the data type and range (if any) of the first output to which it is connected. Sounds to me like you've connected the Broadcaster actor to an actor that has caused it to adopt the range of the other actor like this:

Figure 1: Range of Wave Generator 'value' output property is min:0, max:100

Figure 2: Range for fresh Broadcaster actor's 'value' input is min:MIN, max:MAX

Figure 3: Once connected to the Wave Generator, the range of the Broadcaster actor's 'value' input mutates to match the range of the Wave Generator; min:0, max:100

Thanks for your advice on this. I have looked into what kind of investment would be required to go with a single  computer solution or Datapath FX4’s but the reality is the MacMini M4 is a much better value proposition at this time. With 3 x MacMini I am provided a total of 9 potential discrete video outputs and greater long term flexibility, while remaining well under the current price point of Datapath FX4. At this point It appears to me worth the extra fiddling around with Isadora programming. I do take the point about reducing the over all number of Movie Players, that is a great approach!

Best wishes

@nic Hi - I have been having great success with Nintendo Switch Joycon controllers. They're pretty stable. There is no way to do Wiimotes anymore as all the software to make it work is now defunkt. I think switch joycons are a great alternative - they last a good while, have pretty accurate sensing and have a load of buttons. They also have lots of attachments to turn their form into other shapes, like guns. I've got a project at the minute with my students where we're using ninteno switch joycons in gun style cases to create a big screen shooter experience.

I've tried the VR path, Disguise does VR controllers really well, but it's not worth the effort in isadora, I havent found a way to connect them so far, and I'm a VR loon.

In terms of connecting Joycons to isadora, there are a few ways, there are lots of homebrew apps on git hub like joyOSCmapper which is great, but difficult to customise the parameters. I had much better success with Chataigne the other day. It's a timelining app for OSC messages (VERY useful) but also has native joycon support and you can map joycons to OSC values this way. It's very stable and actually applies some useful smoothing to the data so you get very smooth motion.

Hope that helps :)

(I bought a couple of joycons a few weeks ago at CEX (UK) and they cost about £32 each. Quite dear. you need a method to charge them too, so I had to buy a cheap dock as they only charge when attached to the switch itself..
