This article is about the modelling of flocking behavior. From the perspective of the mathematical modeller, "flocking" is the collective motion of a large number of self-propelled entities and is a collective animal behavior exhibited by many living beings such as birds, fish, bacteria, and insects. It is considered an emergent behavior arising from simple rules that are followed by individuals and does not involve any central coordination. Flocking behavior was first simulated on a computer in by Craig Reynolds with his simulation program, Boids. This program simulates simple agents that are allowed to move according to a set of basic rules.
The result is akin to a flock of birds, a school of fish, or a swarm of insects. Well, I'm going to tell you something, because of Miss Trista here, I think we're going to have women flocking to the doctor's office to get Essure, when women find out about this, they want this procedure. They have been for a very long period of time this kind of staple of the middle class, that doesn't really seem to be the case anymore. If people are not flocking to those brands, you need to be able to look for other audiences and other distribution points.
Charles Krauthammer :. Everyone was flocking around the gate, anxious to get on the flight, there were literally only 50 people in front of her, i have never felt more harassed, disrespected and humiliated in my life. Word in Definition. Webster Dictionary 0. The project's development roadmap is documented in the wiki. Plans include:. Unplanned features, bug fixes, and contributions are welcome and appreciated, of course.
The Flocking project adheres to the Contributor Covenant guidelines , and is an open and welcoming community. The latest stable release of Flocking can be downloaded from the Flocking releases page. Concatenated and minified Flocking builds, suitable for development and production respectively, are included in the dist directory.
Flocking can also be built manually using Grunt. For more information on using Flocking in a browser, read the Getting Started tutorial. Flocking consists of a handful of primary components that are configured using JSON specifications. Unit generators, or ugens for short, are the basic building blocks of synthesis; they do the work of generating or processing audio signals in Flocking. UGens have multiple inputs and a single output. Some unit generators support multiple input or output multiple channels. A unit generator can be wired to other unit generators, supporting sophisticated signal processing graphs.
Unit generators implement one primary method, gen numSamps , which is responsible for processing a block of audio samples. Typically, however, you never need to interact with unit generator instances directly. Instead, you create declarative "unit generator definitions" ugenDefs objects, letting Flocking take care of creating the actual unit generator instances.

UGenDefs are composed into trees called synthDefs. Here's an example of a ugenDef:. A Synth is a self-contained collection of unit generators that represents a synthesizer, instrument, or signal processor of some kind. Multiple synths can run at the same time, and they can be connected together using shared interconnect buses. For example, a mixing board Synth could be created to mix and process signals from several tone-generating Synths and effect Synths.
To create a synth, you specify a synthDef option, which is a declarative tree of unit generator definitions.
Here's a simple example of a sine oscillator named carrier whose amplitude is modulate by another sine oscillator, mod :. Synths can be updated in realtime by using the get and set methods. Any unit generator with an id property in its ugenDef will automatically be exposed as a named input to the synth. To update a unit generator, a key path is used to specify the desired input. Key paths are dot-delimited, path-like strings that allow you to address any part of the unit generator tree.
Here's an example of a key path:. An input can be retrieved from a synth by invoking the get method with a key path. If the target of the path is a value unit generator , its value will be returned directly. If it is any other kind of input, its ugen instance will be returned instead.
Flock And Flocking - Understanding the Flocking process
Synth inputs can be set by calling the aptly-named set method. Flocking's signal processing pipeline is dynamic, so unit generators can be added or replaced at any time. Behind the scenes, everything is a unit generator, even static values. To ensure reasonable performance on resource-constrained devices such as phones and low-power computers e.
Chromebooks, Raspberry Pi , Flocking uses a block-based architecture. By default, ugens and synths will produce 64 samples per block. This value is configurable by specifying the blockSize option when initializing Flocking. There are three primary types of signal rates in Flocking: audio , control , and constant.
Audio rate produces a full block of samples, control rate produces one sample per block, and constant rate will alway produce the same value. Synths also support two other rates, demand and scheduled. A demand rate synth will only produce a value when its gen method is invoked. Scheduled synths are under the control of a scheduler instead of the sample output clock.
An Environment represents a whole "audio system" or "context" in Flocking. It is responsible for evaluating all Synths instances and outputting their samples to the current audio output strategy. An environment manages a list of Synth instances and evaluates them in order. You should instantiate only one flock.
Before you'll hear any sound, the environment needs to be started. You only need to start the environment once. This is done using the start method:.

By default, synths are automatically added to the end or tail of the environment's list of synths. This means that synths will start playing immediately when you create them. Other exposure in the flocking industry can include acrylic adhesives , ammonium ether of potato starch , heat transfer oil , tannic acid , and zeolite.
