Thanks for your help, I use the actor smoother and so far moving my sphere is smoother. Thanks again and see you soon. Thierry.

I'd like to know if there is a way to capture a still from the Vimeo stream using the same actor used in this tutorial to mix the still and moving image in the effects mixer to create a mask.

 Can you use the Capture Stage to Picture actor to grab a still image of the stage? The picture then becomes available to the Picture Player actor allowing you to use that still as a background?

@mark great session, although using MIDI in Isadora for quite a while, you can always learn. Was working last year on a project with a brainsensor connected to piano and drone synthesizers in Reason. Although a EEG brainsensor as such is a simple controller, it needs a lot of handling which is controlled in Isadora. Also the sound triggering and musical evolution, related to brainwave intensity and brain state are managed by Isadora. The baseline is that no other physical intervention is taking place and that the resulting sound is unique for its moment in time. Fun :-)

@woland thanks for posting this - i have so much to catch up with in isadora 3 !

I thought It was because of my projector definition

 What is your projector definition? The higher the resolution the better (obviously) but also understand that the larger the image you're trying to project on a surface, the more visible the individual pixels will be.

Hello everybody.

First of all thank you very much Mark for your excellent work. Your pedagogical qualities are also freat.

I have a question, in relation the guru 13 session:

at one point you use on the actor an .oni file in the first example, i.e. the video film dealing with the cathedral. How did you convert the movie into an .oni file? Why doing so?

Thanks in advance, Jean-Marc Matos

[STAFF NOTE: @kdmatos I moved your question and @Juriaan 's response to this thread so that all the discussion could be kept in one place.]

This was a very interesting session, as usual !

I never made soft edge with 2 or more projectors, but I remember that the position and the distance between the 2 projectors has to be the more precise possible, even if Isadora let user to make changes through Izzymap and Stage Setup.
I found in my notes this drawing which explains how to calculate the best set up, if it's useful for someone.

Best wishes.
Clement

@astrid

Remove the space between ISADORA_FLOAT_PARAM and (

So the second one ;) The first one is your example

// ISADORA_FLOAT_PARAM (noise_level, noil, 0.0, 1.0, 0.5, "This is the text that helps"); // ISADORA_FLOAT_PARAM(noise_level, noil, 0.0, 1.0, 0.5, "This is the text that helps");

Out of curiosity, has there been any development on the OSC web socket that I believe was mentioned in the session

As of now, no. I am focused back on the main Isadora app at the moment. If we can roll that into the fall release, we will. You can read more about our plans in this forum thread.

Best Wishes,
Mark

@juriaan

ah, thanks Juriaan, I missed that. I use OSCrouter a lot, which is a great tool, but still often need other bits and pieces to set up with Isadora when OSCing out of ETC world.

Thanks for the answer.

Have a nice day

Dear Community,

Please find this new "guru session" directory with viewing and download links for all of the guru sessions. We will be updating this list as we add guru sessions in the future.

Thanks to Jan van Hapert for the new "guru" backdrop!

@mark

Belated thanks for this session, and thanks so much for answering my questions. Really appreciated. Look forward to seeing you again when the Guru sessions resume!

My 3D ropes actor assignement.
Not sure if replying here is the way to post an assignement, but here it is. I tried to mimik watching algae move whilst floating above them with a snorkel. Summer feelings came up.

I've got a bit of trouble in properly "repelling" the algae with the mousewatcher (possibly I got lost somewhere in rotating spaces). Anyway it kind of works.

Older machines may struggle a bit, mine almost hits the 50% load.

Cheers to all of you,  (justy noticed that "all of you" sounds pretty similar to "I love you" ...    )

@mark Thank you for a brilliant session! I didn’t have time to join it then. But after seeing it through yesterday, one question emerged into my mind.

Back in the times of Isadora v1.x, I remember reading that using excessively User Actors / Macros with heavy load video processing within them would have slowed down the processing (compared to that that they would be all in the base level – no macros or user actors). 

Hopefully I remember totally wrong, but I would like to ask if – with Isadora v3.x – it makes any difference to compose complicated heavy duty patches using “heavy” actors inside “multi-layered” User Actors or Macros?

Thanks in advance!

roughness, reflection or transparency

 There is no bump map in Isadora, there is no reflections either. You can texture with alpha channel transparency.

Here is a demo patch I created that forces an alpha transparency onto a movie file. The movie files works for MacOS 10.15.

Kind Regards

Russell

Hi @nandada 

The data array is going to be very helpful for what you want to do. I would suggest you determine where your data is coming from and what form it is in. One thing about ocean tides is that there are a number of variables, for example location, time and height. So you would need to consider how to represent the data in a way that is appealing for you and your audience (you may already have that worked out). What are all the variables you want to use? There are parameters you could add such as water temperature, wave height ... so the diversity of data can be interesting to increase/decrease to recreate sonically or visually.

You can access data on the internet through data providers such as those listed as free API sources in this GitHub: https://github.com/public-apis/public-api

Storm Glass has a free plan for up to 50 data requests per day, after that it gets expensive: https://stormglass.io/

It is then about your patch configuration to make sense of how to work with the data collection over time - and this is where the Data Array can be implemented.

If you are interested I have made a demonstration patch that has used free open data from online sources. You are welcome to download it here: https://community. https://github.com/public-apis/public-apis.com/topic/6591/sharing-a-demo-patch-getting-and-parsing-data-from-api-url-s

It requires the JSON Parser plugin provided by @mark here: https://community.troikatronix.com/topic/6503/json-parser-actor-for-macos-and-windows-public-beta

Kind Regards

Russell

@mark you did it great !!! Thank you for all you've done.

Best,
