OpenEXR is a high dynamic-range (HDR) image file format developed by
Industrial Light & Magic for use in computer imaging applications.
OpenEXR is used by ILM on all motion pictures currently in production.
The first movies to employ OpenEXR were Harry Potter and the Sorcerers Stone,
Men in Black II, Gangs of New York, and Signs. Since then, OpenEXR has become
ILM's main image file format.
OpenEXR's features include:
* Higher dynamic range and color precision than existing 8- and 10-bit
image file formats.
* Support for 16-bit floating-point, 32-bit floating-point, and 32-bit
integer pixels. The 16-bit floating-point format, called "half", is compatible
with the half data type in NVIDIA's Cg graphics language and is supported
natively on their new GeForce FX and Quadro FX 3D graphics solutions.
* Multiple lossless image compression algorithms. Some of the included codecs
can achieve 2:1 lossless compression ratios on images with film grain.
* Extensibility. New compression codecs and image types can easily be added
by extending the C++ classes included in the OpenEXR software distribution.
New image attributes (strings, vectors, integers, etc.) can be added to
OpenEXR image headers without affecting backward compatibility with existing
OpenEXR applications.

ABOUT THE ILMBASE LIBRARIES
----------------------------
Half is a class that encapsulates our 16-bit floating-point format.
IlmThread is a thread abstraction library for use with OpenEXR
and other software packages. It currently supports pthreads and
Windows threads.
Imath implements 2D and 3D vectors, 3x3 and 4x4 matrices, quaternions
and other useful 2D and 3D math functions.
Iex is an exception-handling library.

The Jave project is a Java based ASCII-Art-graphic editor. It allows drawing
new images as well as converting JPG-Images to ASCII-Art.
Patch is a spline based 3D modeling tool. It allows to create 3D models which
can be rendered with POV-Ray or RenderMan compatible renderers (e.g. Aqsis).
