Graphite is a package that can be used to create "smart fonts" capable of displaying writing systems with various complex behaviors, such as: * contextual shaping * ligatures * reordering * split glyphs * bidirectionality * stacking diacritics * complex positioning

Converseen is an open source project written in C++ with the powerful Qt4 libraries. Thanks to the Magick++ image libraries it supports more than 100 image formats. You can convert and resize an unlimited number of images to any of the most popular formats: DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF.

GRX is a 2D graphics C library originaly written by Csaba Biegl for DJ Delorie's DOS port of the GCC compiler. Now it support a big range of platforms.

gSculpt is an open source, procedural subdivision modeller. It has a comprehensive set of polygon modelling tools, including most of those found in Wings 3D, and more. Workflow and speed of use are important design goals in the development of gSculpt. Pre-selection highlighting throughout the program, and keyboard short cuts ensure that the workflow is fast and efficient, while providing access to a powerful procedural system which allows mistakes to be rectified easily. Its procedural modelling system makes it an excellent choice for making modelling tutorials, as the steps required to build the model from the beginning are displayed to the user in a list. This list can be navigated easily, allowing a user to view the process one step at a time, at their own pace, while being able too look at the model from all angles as they go. gSculpt can import and export Wavefront Object (.obj) model files.

This port provides OpenGL video elements for Gstreamer.

GTS stands for the GNU Triangulated Surface Library. It is an Open Source Free Software Library intended to provide a set of useful functions to deal with 3D surfaces meshed with interconnected triangles. A brief summary of its main features: - Simple object-oriented structure giving easy access to topological properties. - 2D dynamic Delaunay and constrained Delaunay triangulations. - Robust geometric predicates (orientation, in circle) using fast adaptive floating point arithmetic. - Robust set operations on surfaces (union, intersection, difference). - Surface refinement and coarsening (multiresolution models). - Dynamic view-independent continuous level-of-detail. - Preliminary support for view-dependent level-of-detail. - Bounding-boxes trees and Kd-trees for efficient point location and collision/intersection detection. - Graph operations: traversal, graph partitioning. - Metric operations (area, volume, curvature ...). - Triangle strips generation for fast rendering.

The port of GLExcess, an impressive OpenGL graphics demo.

GLFW is a free, Open Source, multi-platform library for OpenGL application development that provides a powerful API for handling operating system specific tasks such as opening an OpenGL window, reading keyboard, mouse, joystick and time input, creating threads, and more.

光影魔幻工业特效，卢卡斯数字有限公司的一个部分。LLC，在2000年夏 天实现了它自己的扩展动态光照渲染文件格式。那时现有的8位文件格式 无法准确地再现图像黑暗和明亮区域间的极端对比和图像的非常微妙的色 彩层次。 ILM的扩展动态光照渲染文件格式已经被成功地使用在电影《哈利·波特》、 《黑衣人II》和《灵异象限》。ILM的一些表演就是使用的这个新格式。 意识到其他一些人对扩展动态光照渲染文件格式也有兴趣，ILM决定把 他的新的文件格式精炼一些并发布。于是OpenEXR出现了。
