Gaffer is a general purpose node-based application designed for use in the visual effects industry. It provides basic tools for procedural scene generation, shader authoring, rendering, and image compositing.

Powerful
Based on a multithreaded deferred scene evaluation engine, Gaffer allows you to handle large scenes and develop flexible procedural work-flows.

Renderer Agnostic
Gaffer utilises a renderer abstraction layer allowing it to export to your favourite renderer (assuming for now that your favourite renderer is either Arnold or 3Delight).

Customisable
Gaffer is built to be customisable throughout. Be it a simple scripted configuration tweak, complex expression, custom node or user interface, even a full blown application, Gaffer’s open APIs enable you to do what you need.

Extensible
Feel free to add new renderers, new nodes, or integrate with your renderfarm. With Gaffer derived apps you could have new types of data flowing through the node graph, such as asset dependencies or simulation operations.

Open Source
Distributed under the BSD license, Gaffer builds upon a wealth of open-source VFX libraries including OpenEXR, OpenImageIO, OpenColorIO, Cortex and of course the Gaffer frameworks themselves.

Unfinished
Although Gaffer is becoming more capable by the day, it still lacks in features and useability. Itching to fix a bug or contribute a cool new enhancement? Want to add support for OpenVDB, Bullet or another renderer backend? Fork it on GitHub…

Compiled binary releases are available for download from the releases page.

Dynamica is a plug-in for Maya that provides an interface to the Bullet rigid body engine. Bullet was originally created to simulate many rigid bodies quickly in a game context, but this plug-in helps extend its usefulness to film production. The Walt Disney Animation Studios used this plug-in to model the thousands of packing peanuts seen in BOLT.

Features of the Dynamica Maya plugin

  • Dynamica is cross-platform and works on Windows, Linux and Mac OSX
  • Dynamica runs on all versions of Maya.
  • Active, passive, and kinematic rigid bodies
  • Sphere, Box, Hull(convex), and Mesh(concave) collision shapes
  • Force breakable Nail, Hinge, Slider, and Six-degrees-of-freedom constraints
  • Frame based choreography control and simulation baking
  • The plugin exports to COLLADA Physics format and the native .bullet binary physics file format

It was used by Disney Animation and several other studios.

OpenSequencePlayer, aka Duke, is a basic opensource high resolution image sequence player dedicated to visual effects and post-production companies.

Duke relies on a plug-in system for input formats (some are provided by OpenImageIO, others are dedicated plug-ins like JPEG or DPX), so it covers most of the image sequences needed by everyday VFX checking on Linux®, Windows® and Mac OSX® platforms.
Other components are based on generic libraries and proven technologies like OpenGL, Cg and Protocol Buffer.

Duke’s built-in lookahead file cache ensures stable playback for either direct from disk or RAM sources.
Duke’s modular engine enables color corrections and playlist management facilities as well as a timeline, or forthcoming features like 3D stereo, split screen, …

OpenBatchIO, aka Tuttle

TuttleOFX is an open source image sequences processing frameworkmade up of :

  • a set of plugins to read and write professional VFX image formats and to perform various image processings (color corrections, filters, video compression, …)
  • a set of command line tools called Sam to browse, copy, move, delete and batch process the aforementioned plugins.

OpenFX Architecture

  • The aim of TuttleOFX is to help post-production facilities to deal with large-scale everyday image processing tasks. Compared with other programming libraries and image processing tools, TuttleOFX is based on some extended OpenFX plugins architecture, combined with optimised selection bit-depth processing.

Support For Numerous Processes

  • In addition of standard process features, TuttleOFX also addresses requested VFX processes like lens-distort corrections or movie compression and even some more specific color treatments like Color Transform Language and OpenColorIO nodes.

Support For 3rd Party Applications

  • Thanks to their OpenFX nature, TuttleOFX plugins can be used either in the Sam command line tool or by other applications such as Nuke® (The Foundry), Scratch® (Assimilate), Baselight® (FilmLight), Mistika® (SGO). Similarly, commercial OpenFX plugins (Sapphire, Furnace, Keylight, …) can be used within Sam command line.
