<title>Clutter</title>

<p>Clutter is a library for doing animations and using a 2.5-D canvas.
You create graphical objects out of images, and you can manipulate
them later to move them, rotate them, or give them quasi-3D
effects.</p>

<p>Clutter использует промышленные стандартные программные интерфейсы <link href="http://www.khronos.org/opengl/">OpenGL</link> и <link href="http://www.khronos.org/opengles/">OpenGL|ES</link> для доступа к ускоряющим аппаратным средствам рабочих станций и мобильных сред не внося при этом сложности в конвейерное программирование GPU.</p>

<p>Clutter does not specify any visual style, and does not provide any
pre-defined complex user interface control; it lets the developer define what
is needed, using a flexible scene graph API, with free-form placement of the
scene elements (or <em>actors</em>) on the main viewport (or <em>stage</em>).</p>

  <p>Clutter comes with pre-defined actors for displaying solid colors, image
  data, text and custom high-precision 2D drawing using the
  <link xref="tech-cairo">Cairo</link> API. Clutter also provides generic
  classes for structuring a user interface using both a box-packing model like
  <link xref="tech-gtk">GTK+</link>, and a series of free-form
  <em>constraints</em>.</p>

<p>Clutter provides an extensible animation framework and graphical
effects. An animation is associated with a timeline and changes one or
more properties of one or more actors over time, for example their
rotation in a particular dimension, scale, size, opacity, etc.</p>

<p>Существует несколько сторонних библиотек для стыковки с другими технологиями: Clutter-GTK, для встраивания сцены Clutter внутрь приложения GTK+; Clutter-GStreamer, для встраивания видео и аудио конвейеров GStreamer; Clutter-Box2D и Clutter-Bullet, для добавление физического взаимодействия в 2D и 3D окружения.</p>
