5 Projects Released to Global Community via http://opensource.imageworks.com

CULVER CITY, Calif., July 30 /PRNewswire/ -- Sony Pictures Imageworks, the
award-winning visual effects and digital character animation unit of Sony
Pictures Digital Productions, is launching an open source development program,
it was announced today by Imageworks' chief technology officer, Rob Bredow.
Five technologies will be released initially:

    --  OSL, a programmable shading language for rendering
    --  Field3d, a voxel data storage library
    --  Maya Reticule, a Maya Plug-in for camera masking
    --  Scala Migration, a database migration tool

    --  Pystring, python-like string handling in C++



Imageworks' production environment, which is known for its photo-real visual
effects, digital character performances, and innovative technologies to
facilitate their creation, has incorporated open source solutions, most
notably the Linux operating system, for many years.  Now the company is
contributing back to the open source community by making these technologies
available.  The software can be used freely around the world by both large and
small studios. Each project has a team of passionate individuals supporting it
who are interested in seeing the code widely used.  The intention of the open
source release is to build larger communities to adopt and further refine the
code.

"Some of the smartest and most dedicated engineers in computer graphics have
put their experience and passion into the development of these tools," stated
Rob Bredow, "and we are very excited to be able to share them with a much
wider audience."

To launch these open source technologies, Imageworks engineers will be at
SIGGRAPH, the international conference of computer graphics held this year in
New Orleans, August 3-8.  There will be a "Birds of a Feather" meeting around
the topic of voxel data storage, on Thursday, August 6 at 9:30 AM in room 287
at the Ernest N. Morial Convention Center.  Imageworks is also launching a
website to keep the developer community updated on its open source projects at
http://opensource.imageworks.com.

While proprietary technologies have long characterized the visual effects and
animation industry, recent years have seen increasing adoption of commercial
technologies with proprietary solutions serving more specialized needs.  With
more productions shared between multiple companies and more mobile artists,
standards and common technologies enable greater interaction.  The industry's
first significant effort in this regard was in 2003 when ILM released OpenEXR,
a 16-bit, floating-point file format system.

Highlights of the release include the following:

Field3D
Field3D is an open source library for storing voxel data. It provides C++
classes that handle storage in memory, as well as a file format based on HDF5
that allows the C++ objects to easily be written to and read from disk.

The library was initially developed at Sony Pictures Imageworks as a
replacement for the three different in-house file formats already used to
store voxel data. It is the foundation for Imageworks' in-house simulation
framework and volume rendering software. It is actively used in production.

Scala Migrations
Scala Migrations is a library to manage upgrades and rollbacks to database
schemas.  Migrations allow a source control system to manage together the
database schema and the code using the schema.  It is designed to allow
multiple developers working on a project with a database backend to design
schema modifications independently, apply the migrations to their local
database for debugging and when complete, check them into a source control
system to manage as one manages normal source code.

The package is based off Ruby on Rails Migrations and in fact shares the exact
same schema migration table to manage the list of installed migrations.  The
Scala Migrations library utilizes the clean Scala language to write easy to
understand migrations.  Scala Migrations provides a database abstraction layer
that allows migrations to target any supported database vendor.

OSL (Open Shading Language)
Open Shading Language (OSL) is a small but rich language for programmable
shading in advanced renderers and other applications.  OSL is similar to C, as
well as other shading languages; however, it is specifically designed for
advanced rendering algorithms with features such as radiance closures, BRDFs,
and deferred ray tracing as first-class concepts.

The OSL project includes a complete language specification, a compiler from
OSL to an intermediate assembly-like byte code, an interpreter that executes
OSL shaders on collections of points in a SIMD manner, and extensive standard
shader function library.  These all exist as libraries with straightforward
C++ APIs, and so may be easily integrated into existing renderers, compositing
packages, image processing tools, or other applications.  Additionally, the
source code can be easily customized to allow for renderer-specific extensions
or alterations, or custom back-ends to translate to GPUs or other special
hardware.

Pystring 
Pystring is a collection of C++ functions which match the interface and
behavior of python's string class methods using std::string.  Implemented in
C++, it does not require or make use of a python interpreter.  Rather, it
provides convenience and familiarity for common string operations not included
in the standard C++ library.  It's also useful in environments where both C++
and python are used.

Maya Reticle
Originally developed at Sony Pictures Imageworks, spReticleLoc is a Maya C++
plug-in plus MEL code that creates a reticule for a camera.  It allows for
various camera reference masks to be displayed when looking through the
camera, such as filmback, projection gate, and pan and scan attributes

The value of predefined parameters can be displayed in selectable areas, such
as the camera focal length and name, current aspect ratio, frame number, name
of the show and shot, Maya scene file name, current user name, etc.  Arbitrary
textural information can be displayed as well.

ABOUT SONY PICTURES IMAGEWORKS
Sony Pictures Imageworks Inc. is the Academy Award(R) winning,
state-of-the-art visual effects and animation unit of Sony Pictures Digital
Productions. The Imageworks production environment supports live-action visual
effects and character animation, all-CG animation, Imageworks 3D stereoscopic,
and  Imageworks Interactive, a full service creative group that produces
websites and supports digital marketing for the studio and outside clients.

Imageworks' achievements have been recognized by the Academy of Motion Picture
Arts and Sciences with Oscars(R) for its work on SPIDER-MAN(TM) 2 and the CG
animated short film THE CHUBBCHUBBS!. In 2008, SURF'S UP was nominated for the
Academy Award for Best Animated Feature. In 2007, two of Imageworks' projects,
SUPERMAN RETURNS and the all-CG animated feature MONSTER HOUSE, were nominated
for Academy Awards in the Outstanding Achievement in Visual Effects and Best
Animated Feature respectively. With those two nominations, Imageworks became
