Non of the listed software tools are capable of doing a perfect mapping of this curvy front easily. Only very expensive media server, like disguise or Pixera can do the 3D calculations on the fly and add accurate edge blend.

considering your very short time frame, I would go the simplest route.

Just do separate layers. There are several ways to generate several layers in Isadora. For the most flexible way, use multiple projectors per scene. Every projector offers his own layer value and izzi map function. With the right blend mode set, you can send these projectors to the same stage.

Projector/ Layer 1: The background with pre cut video or a masking in izzi map.
Projector/ Layer 2: The pillars and general front.
You could even go with a projector actor for each object you'd like to map separately.

For the masking use an extra layer which goes to a virtual stage. With this you can do a very flexible (alpha-) masking within izzy map.

Do this for every layer you feel to need a separate mapping. If you need to warp each layer separately, pipe them through a virtual stage as well, before finally adding them to the masking layer with the keying (a separate one, then)

An edge blend is very complex here (as is the whole thing because of the curves and levels).
But you can do a simple manual edge blend with a similar technique, using a virtual stage and do the edge blend actor on it.

Regarding the calculations for the hardware projectors, you should use the foremost front as the projection screen. everything behind it, will be overlapping anyway.

PS: I used a chroma key for the masks, as in my experience the luma doesn't work as well.

The simplest way would be to use the Capture Stage to Picture actor to get a still image "thumbnail" of what each Scene looks like, then put a Picture Player actor in each Scene showing the picture taken of the next scene, and link the output of the Picture Player actor to a Monitor Control.

The solution here:

BING copilot translated the JSON to HEX and pasted it in the TCP send actor. Worked straight away!

Here are a couple of example patches I made in the past covering this topic. They're probably similar to what @bonemap already posted, but maybe they'll be helpful too.

It's not exactly what you're asking for, but here's some resources that might help you learn more about this concept in Isadora:

Example file I created that covers the basics of motion-tracking: https://troikatronix.com/add-ons/tutorial-basic-motion-tracking/

In-depth live-stream Guru Session by Mark Coniglio, the creator of Isadora, focused entirely on motion tracking with the Eyes++ actor: https://www.youtube.com/watch?v=RKSwV4vjq7o

Example project file I made for someone on the forum that used motion tracking to trigger things: https://community.troikatronix.com/topic/6213/dining-experience-using-isadora-advice-please/6?_=1711366182217

Will do!

@woland

Thank you so much for this detailed answer to my questions!!!

This is very helpful!

Hi!

My Audio card is Realtek(R) Audio.

Thanks for your help!

@nitnatnoe

I recommand the NDI way with a good gygabite (minimum) ethernet link and a properly configured network.

The HDMI way its also CPU hungry, you are limited with the distance between machines, you must buy a card and the settings are not so trivials.

With a proper network, you can also send other informations from TD to Izzy and vice versa.

There's also a written tutorial here: https://support.troikatronix.com/support/solutions/articles/13000046020-how-to-run-multiple-scenes-simultaneously-using-the-activate-scene-actor

@dillthekraut lots of places have fibre, especially for very long runs. Reels of rugged cat7 are multi use so they are pretty popular. This is especially true when you only need a single converter when the projector has built in hdbaseT

Should we be concerned that you are needing motivation? 

Nah, I just ran across this while looking for something else and found this (though I appreciate the concern). Past me didn't have easy access to a printer but present me does. I like to keep little mementos around my desk that make me happy and I thought this would be a nice addition. <3

Oh whoops I put a screenshot from Isadora 2 from an old post because it looks really similar to what I was actually trying to show which is this:

I edited my post above to remove the incorrect information.

It can be done in a myriad of ways, using multiple hardware and software combinations. Neither will be easy or hard. It all depends on skill and - in the end - time and money.

Hello,

For best results when working with particles you can adjust 'frame rate' and 'service task' properties in the Isadora settings (menu: Isadora/Settings).

Set preferences that will be best for the capacity of your computer. For example: Target Frame Rate - 30 FPS and General Service Tasks - 5x Per Frame.

Once you have made your setting enter the same values into the 'Calculate optimised Pulse triggers and Particle Count' User actor.  That is included in the demonstration patch available here.

This will calculate the available frequency range for your particle parameters based on Isadora Preference settings.

 So...

1/ The pararmeter for the Frames Per Second is first set in the Isadora Preferences.

2/ The parameter for General Service Tasks is first set in the Isadora Preferences.

Calculate the efficient number of particles based on the Pulse trigger frequency and total life span of the particle.

3/ set Fade-in time 

4/ set Hold time

5/ set Fade-out time

RESET the user actor. 

Keep an eye on the LOAD rating and if it goes too high reduce the settings in the Isadora Preferences and reenter the new settings accordingly.

You will still achieve an acceptable particle effect at Target Frame Rate 24 FPS and General Service Tasks - 12x Per Frame. If your computer is struggling try Target Frame Rate 15 FPS and General Service Tasks 15x Per Frame.… be kind to your computer!

@jfg, @bonemap @CitizenJoeGreat,
Thanks that worked:) really nice!

The times are delayed so all three videos stop at the same time and fade to black. Is that possible?

Triggering Things in a Sequence in the Same Scene

Enter Scene Trigger actor > Timed Trigger Actor > Sequential Trigger actorAlternatively: Enter Scene Trigger actor > Timer actor > Comparator actors looking for each time when there's supposed to be a trigger.Set the 'mode' of the Comparators to greater than or equal to ("ge")Initialize the first value input of each Comparator at '0'.Connect the output of the Timer actor to the first value input on each Comparator actor.Note that the Timer actor outputs milliseconds, so if you want a trigger at 3 seconds, put "3000" into the second value input of the Comparator actorFade in and fade out within the same Scene can be handled by Envelope Generator actors hooked up to either a Video Fader actor, a Video Mixer actor, or the 'intensity' input of a Projector actor.

Triggering Things Across Multiple Scenes/With Scene Transitions

Enter Scene Trigger actor > Trigger Delay actor > Jump actor if you want a scene to automatically jump to the next oneFade in and out while transitioning between Scenes can be handled by the Jump or Jump++ actors' fade inputs.Fade in and out of background Scenes can be handled by the Activate Scene Amount actor in combination with Envelope Generator actors.

@woland Thanks L much appreciated!
