Its true, most video artist working on the windows platform have been jealous of the Mac only video sharing technology called Syphon for a few years. We all heard rumors, saw threads, sites, and github pages that had the beginnings of what was aptly named Wyphon. Just a few days ago, quietly under the radar, a new project was made public, Spout. Spout is OpenGL video sharing for Windows.

Web API's in Isadora: part 1

Posted by on 13 March 2014 | Comments

What is a web API?
Web API's are sets of communication channels that are defined by a web application/service for the input and output of data. API strictly means: application programming interface.
Using web API's we can interact with data from a web service. View the latest Twitter post, or check how many people like your Facebook page. Really the possibilities are huge, and I am not here to try to suggest cool ways to use web data with Isadora, but rather to introduce the Isadora actors required to communicate with an API.

Using only native Isadora shape elements, freeframe fxs and logic (more on this later HERE)..
This video uses real-time collision detection to control a number of display attributes.
You can see both the Orb change in color and size when the collision between it and the floating Rect is true, as well as; the Rect it self changes.

White Room Event

Using a custom midi controlled Isadora show, I triggered and mixed a series of pre-developed real-time video composites. The show was designed with one common element between all scenes, a additive red bar that would pan horizontally to the rhythm of the music.
I used this red saturation as a trigger for 2 DMX par cans with red gel filters, that would activate anytime the color the corresponding side was within range.. giving the effect of extended projection reach.. or at least a larger stage space.

User Actor On/Off

 I spend a lot of my time creating User Actors in Isadora. User Actors are possibly the most powerful internal building block that Isadora offers. They allow you to create a library or code/patch objects, that you can save externally, but the most powerful feature is probably that fact that multiple instances of a User Actor can be updated by simply updating one in your patch and allowing Isadora to update the rest for you when you close the User Actor.
My favorite way to optimize a large patch it to use a User Actor specific actor, 'User Actor On/Off', this actor works like bypass on most every other actor, in that it will allow you to shut off the processing of a User Actor, but unlike bypass in that inputs do not make it thru to the outputs. This means when you turn off a User Actor with the 'User Actor On/Off' actor that it is dead, and a dead end to all inputs.
This is an amazing way to save CPU cycles when you are switching between features (used HEAVILY in Syst3m to allow video FX and ALL other features).

spectacle for Ayria

As a follow up to last weeks post about the beginnings of a new DMX control matrix, I put together a quick screen-capture. In the video you will hear song by Ayria named Bad List, while working on this project I am using the full (as recorded to CD) versions of the tracks, so that I can set time triggers based on vocal or musical elements. These completed tracks will be replaced for the live show with simplified beat tracks so that the live performers are playing synced to the lighting controls. I will not be on tour with the band, therefore; the project needs to made simple and portable, for this reason I did not want to introduce any additional IO like midi or Open Sound Control.
