DX – Advanced Envelope Scrubber

The Advanced Envelope Scrubber actor provides a powerful ‘timeline’ tool that handles the display of numerous child scenes over time.

It is a sort of framework for working with sequences of scenes. The child scenes are run from a Parents’ position (as %), making it is very easy to link the controls to either Video or Audio playback. Originally designed to allow child scenes to be sequenced to a Parent scene playing a long audio file.

The attached ZIP file contains both the User Actor and an example file that plays through two groups of scenes. Each Parent scene has a timer that provides a value ranging 0-100 much like the position output of a Movie Player.
(My Timecode tools provide User Actors which make it easy to integrate with the use of Timecode in the Movie Player)

Features:

  • Attack, Sustain and Release values
  • Visual graphing of the envelope for easier editing
  • Curves can be assigned for each segment of the envelope
  • Child scenes can use the Parents scene intensity for crossfades
  • Works well with Layering Mode ‘Ungrouped’ for advanced video compositing

Requirements:

  • Part of the graphing feature uses the Grapher addon, but the basic graph and visualization of the envelope work without it.

 

 

DX – JS – Grid Positions – example

Create an list of X Y position coordinates that create a grid using Javascript.

In this example patch I use some Javascript to split the Isadora stage into a centered grid. I have used this in a number of my own projects, so I thought I would share this now.

The project requires the JSON parser plugin: https://troikatronix.com/add-ons/json-parser-json-bundler/

It isn’t used heavily, and you could remove it from the project pretty easily. For now I have it included.

 

I have created 3 sample scenes all using the same grid factors 1x2x3 = 6, so we have these possible layouts: 2×3 , 3×2 , 1×6 and 6×1.

You could adjust these samples scenes to use: 1x2x2x3 = 12 producing six layouts or what ever other combination you like. More factors and possibilities mean more X,Y connections.

The sample scenes are:

  • Hexagons are drawn to the stage in alternating pattern grids each with some random settings and animation.
  • Text Blocks (listing the XY values for each) much like the Hexagons but using an optimized reader approach for text animation
  • Line Grid creating a colored grid of animated vertical and horizontal lines which draw the grid divisions

The included images show a few layouts of each sample scene.

ZoomOSC User Actors & Template File

User Actors and a template file for working with Liminal Entertainment Technologies’ software ZoomOSC. These User Actors and this Isadora template file aim to make it as easy as possible to get up and running with ZoomOSC. If you’ve already set up OSC communication between Isadora and ZoomOSC by changing the required settings in ZoomOSC, then this file is plug-and-play (meaning it should work immediately without any adjustments or setup on the Isadora side).

Changelog v10 (2021-12-14):

  1. Added a Scene called “Example Functions” that outlines some basic functions that can be performed with the User Actors.
  2. Added a Scene called “Chat Commands” that outlines how to create chat commands.
  3. There are two new User Actors in the User Actors folder: “Chat Command” and “Chat Command Settings”.
  4. Moved the “Liminal 48 Zoom Selector” to its own Isadora file.

Changelog v8 (2021-12-1):

  1. Note: If you already have the User Actors in your Global User Actors Folder, trash your current version of the “Chat Parser” and “Chatbot Response” User Actors and get the new ones from this download.
  2. Simplified the setup by combining the four necessary setup User Actors into a new User Actor “ZoomOSC Setup”. (If you want to use this User Actor in other files, you’ll need to put it into your Global User Actor Folder.)
  3. Updated the instructions slightly in the “Show Template” Scene.
  4. Added a new example Scene “Marco Polo Chatbot”.
  5. Fixed a parsing bug in the Chat Parser User Actor.
  6. Fixed a parsing bug in the Chatbot Response User Actor.
  7. Added a description of the 3-Value Comparator inside the User Actor and the “Javascript (User Actors)” Scene.
  8. Added explanations on how to do custom settings for OSC Channels, UDP Addresses, and Ports in the “Setup (User Actors)” Scene (scroll down).

Changelog v7 (2021-11-15):

  1. Added a “ZoomOSC Setup” Scene + Screenshot of ZoomOSC Settings
  2. Added an example chat-parsing Scene
  3. Added all User Actors in a folder

Minimum System Requirements: macOS Mojave or Windows 10

The RTMP Streamer Actor is compatible with macOS Mojave and later or Windows 10. It will not run appear in Isadora if you are running macOS High Sierra or earlier. The macOS version of this plugin has been compiled to run natively on both Intel-based and Apple silicon (ARM/M1) based computers.

Minimum Isadora version: 3.1

This plugin works in Isadora 3.1 or later. It will not show up in earlier versions of Isadora.

Leap Motion Watcher

Leap Motion Watcher for Isadora 3.1 or Later

(Please read below regarding about installing the Leap Motion drivers, and how to run this plugin on an Apple Silicon based Mac.)

The Leap Motion Watcher measures the movement of your hands above a Leap Motion controller. This actor reports the position of your hands in three dimensions (x/y/z), the the rotation of the hands (roll, pitch, and yaw), and, when two hands are visible to the controller, the angle and distance between the hands. In addition, on macOS only, certain gestures (swipe, circle) can also be recognized.

Prior to Isadora 3.1, the Leap Motion Watcher plugin was included with the Isadora application. Since the makers of the Leap Motion controller have no plans to offer an Apple silicon (ARM/M1) version of the Leap Motion SDK, we moved this actor out of the main Isadora application and are offering it here as a separate add-on.

Install the Leap Motion Drivers First!

You need to install the Leap Motion drivers for macOS or Windows before using this plugin. At the time of this writing these drivers were located on this page of the Ultraleap website. If that link doesn’t work, try searching for: download leap motion hand tracking to find the page with these drivers.

Using This Add-On on Apple Silicon Based Macs

If want to run this plugin on an Apple Silicon (ARM/M1) based Mac, you’ll have to enable Intel emulation (Rosetta) mode on the Isadora application after installing the Leap Motion drivers.

Using This Add-on on Intel Macs and Windows Computers

If you are using this plugin on an Intel based Mac or on a Windows computer, just install the drivers and start using the actor.
