Cast3D is 3D animation framework library for Adobe Flash in ActionScript3. The foundation is a multi key-framed geometrical animation. Cast3D supports geometry and texture morphing, skin animation, 3D sound, animated movie and video. A number of animation interpolation splines is implemented to provide smooth and natural motion, like Bezier, TCB, Hemite(cubic), Cosine and Linear.

This is a skeletal animation library designed to load and play skeletal animations. It supports models that are composed of several swappable meshes bound to a single skeleton that can be driven by multiple animations. Animadead was written in C++ and has no dependencies. However, example implementations are provided that use OpenGL and SDL.

PulpCore is a free, open source (BSD license) 2D rendering and animation framework for the Java plug-in. It allows Java developers to create modern-looking 2D web games with a strong focus on animation and positive user experiences. Also, PulpCore is designed for ease of development with an intuitive API and a smooth, uninterrupted workflow.

Animata is an open source real-time animation software, designed to create animations, interactive background projections for concerts, theatre and dance performances.

VisIt is a free interactive parallel visualization and graphical analysis tool for viewing scientific data on Unix and PC platforms. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes. VisIt was designed to handle very large data set sizes in the terascale range and yet can also handle small data sets in the kilobyte range.

A technique and philosophy for controlling computer animation is discussed. Using the Actor/Scriptor Animation System (ASAS) a sequence is described by the animator as a formal written SCRIPT, which is in fact a program in an animation/graphic language. Getting the desired animation is then equivalent to "debugging" the script. Typical images manipulated with ASAS are synthetic, 3D perspective, color, shaded images. However, the animation control techniques are independent of the underlying software and hardware of the display system, so apply to other types (still, B&W, 2D, line drawing ...)

We present a visual language for the creation of simple 2D animations within a sketch-based interface. Motions are represented by motion paths, which are drawn as arrows. Events are used to synchronize disparate motions, marking where along motion paths multiple entities should be at the same time. Reuse of animations is supported with the notion of animation functions, which allow previously specified motions to be played back.
