The Graphics Transformation Languages is a set of libraries for using and
integrating transformation algorithms (such as filter or color conversion) in
graphics applications.
The goal is to provide the tools, languages and libraries to create generic
transformation for graphics. Those transformations could then be used by
different programs (Krita, The Gimp, CinePaint, gegl...).
Currently the focus is on developing two languages, designed for two different
implementations.
- OpenCTL which is a GPL compatible of the Color Transformation Language, this
language is dedicated at transforming the value of a single pixel (for
instance brightness adjustement or desaturate). CTL is designed to be part of
the Color Management process.
- OpenShiva is inspired by Adobe's Hydra language from the AIF Toolkit, Shiva
is a language that apply a kernel-like transformations on an image, that means
it works using more than one pixel.
OpenImageIO is a library for reading and writing images, and a bunch of
related classes, utilities, and applications.
There is a particular emphasis on formats and functionality used
in professional, large-scale animation and visual effects work for film.
OpenImageIO is used extensively in animation and VFX studios all over the
world, and is also incorporated into several commercial products.
The OpenJPEG library is an open-source JPEG 2000 library developed in order to
promote the use of JPEG 2000.
The main part of the project consists in a JPEG 2000 codec compliant with the
Part 1 of the standard (Class-1 Profile-1 compliance).
Besides this main codec, OpenJPEG integrates several other modules:
- JP2 (JPEG 2000 standard Part 2 - Handling of JP2 boxes and extended multiple
component transforms for multispectral and hyperspectral imagery)
- MJ2 (JPEG 2000 standard Part 3)
- JPWL (JPEG 2000 standard Part 11)
- JPIP (JPEG 2000 standard Part 9)
- OPJViewer, a GUI viewer for J2K, JP2, JPWL and MJ2 files

OpenJUMP is an open source GIS software written in Java. It is based on
JUMP GIS by Vivid Solutions. It's features include:
* It is a Vector GIS that can read rasters as well.
* OpenJUMP is known to work on Windows, Linux and Mac platforms, but
should work on any operating system that runs Java 1.5 or later.
* It is not just another free demo viewer, but you can edit, save,
analyze etc. with JUMP / OpenJUMP.
* It works, even with medium size datasets, and with professional
touch.
* It provides a GIS API with a flexible plugin structure, so that
new features are relatively easy to develope around the sound
mapping platform.
* It utilises standards like GML, WMS and WFS.
* It is already translated in English, Finnish, French, German,
Italian, Portugese and Spanish. The translation in other languages
is in progress.

The openNURBS Initiative provides CAD, CAM, CAE, and computer graphics software
developers the tools to accurately transfer 3-D geometry between applications.
openNURBS is an open source toolkit for reading and writing models in the 3DM
format
OpenRM Scene Graph is set of tools and utilities that implement a
high performance, flexible and extendible scene graph API. Underneath
OpenRM, OpenGL(tm) is used as the graphics platform for rendering,
so OpenRM is highly portable and can deliver blazing rendering speeds.
OpenRM can be used on any platform that has OpenGL, and has been
built and tested on:
x86 Linux (s/w via Mesa, h/w using vendor drivers, e.g., nVidia)
Irix
Solaris
FreeBSD
Win32 (95/98/NT/2K/ME).
OpenRM is a derivative work of RM Scene Graph (tm), a commercial
scene graph product from R3vis Corporation. Late in 1999, R3vis announced
the release of OpenRM into the Open Source community, with the
OpenRM debut occuring on 1 March 2000. R3vis continues to maintain
and develop RM Scene Graph, which contains additional features not
present in OpenRM.
Deegree iGeoPortal is the web-based portal framework of deegree. It
offers visualization of geodata through a standard web browser like
Mozilla, Firefox or MSIE.
OptiPNG is a PNG optimizer that recompresses image files to a smaller
size, without losing any information. This program also converts
external formats (BMP, GIF, PNM; TIFF support is coming up) to optimized
PNG, and performs PNG integrity checks and corrections.
The idea has been inspired from pngcrush, and is explained in detail in
the PNG-Tech article "A guide to PNG optimization". The implementation
is carried forward in OptiPNG, which offers a faster execution per
trial, and a wider search space.
The Open Scene Graph is a cross-platform C++ OpenGL library for the
real-time, photo-realistic rendering of large 3D models. Uses range from
visual simulation, to scientific modelling, to games, to whatever you can
think of!
