SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

Complete solution for HDR photography
Luminance HDR is a complete suite for HDR imaging workflow. It provides a wide range of functionalities, during both the fusion stage and the tonemapping stage. Its graphical user interface, based on Qt5, runs on a variety of platforms, such as Microsoft Windows, Mac OS X 10.9 and later and several Unix flavors (Linux, FreeBSD and others). Input images can be supplied in multiple formats, from JPEG to RAW files. In the same way, output can be saved in many different formats as well, from JPEG to TIFF (both 8 bit and 16 bit per channel), enabling all the power of your post processing tools.
A full featured cross-platform image library

A project that has moved to GitHub
GLFW is an Open Source, multi-platform library for creating windows with OpenGL contexts and receiving input and events. It is easy to integrate into existing applications and does not lay claim to the main loop. GLFW has moved to GitHub: https://github.com/glfw
LibVNCServer/LibVNCClient are cross-platform C libraries that allow you to easily implement VNC server or client functionality in your program.
Graphic Live Mixer
GLMixer performs real time graphical blending of several movie clips and of computer generated graphics. Drop video files in the mixing workspace and place them in a circular area to change their opacity ; if you selects two videos, moving them together performs a fading transition. This principle generalizes to a large number of videos. Direct interaction with the video allows to be fast and reactive, and to move and deform them on screen. The output of your operations is shown in the output window, typically displayed in full-screen on an external monitor or a projector. But the output can also be saved as a video file. Control GLMixer through network using OpenSoundControl, and generate graphics with ShaderToy GLSL code.

Unofficial Windows builds of FontForge
The aim of this project is to compile up-to-date Windows builds of FontForge. For 'stable' builds, see https://github.com/fontforge/fontforge/releases The build system used was based off that offered by Matthew Petroff (http://www.mpetroff.net/software/fontforge-windows/), but has since been practically rewritten. New in 31/07/2017: * Synced with 20170731 release * Compiled run_fontforge with Visual Studio to avoid antivirus false positives (r2) New in 07/04/2016: * Fixed crash in kern pairs dialogue * Fixed preferences window being too large New in 05/04/2016: * Synced with 20160404 release New in 27/08/2015: * Fix bug in saving fonts/files. New in 25/08/2015: * Synced with 20150824 release New in 14/06/2015: * Fixed bug in the display of window titles KNOWN ISSUES: * No collab support. Unlikely to be added. * CTRL-C from console no longer interrupts/stops FontForge
Volocian believes first and foremost that financial status shouldn’t be a barrier to entry in multimedia content creation. Whether you want to design a product or website, record a band, remix a song, or produce a feature length movie with professional post production graphics and effects, Volocian™ wants to help, even if you’re using borrowed hardware with no previous experience. We provide affordable products and services for any budget, including cost-free solutions for education and demo purposes, while everything we do is designed with ease of use and flexibility in mind, to suit everyone from novice hobbyists to expert professionals. Wherever possible, Volocian™ relies on free, open source, and cross-platform software to prevent vendor lock-in, planned obsolescence, and software as a service licensing. While we remain pragmatic about the use of proprietary software, as we’re aware of the feature limitations of some open source solutions, free solutions are preferred.

C/C++ library to add light and intuitive GUI to OpenGL and DX programs
AntTweakBar is a small and easy to use C/C++ library that allows programmers to quickly add a light and intuitive GUI into OpenGL or DirectX based programs to interactively tweak parameters on-screen. AntTweakBar works with Linux, Windows and OSX, and can be easily integrated with custom windowing system or with existing toolkits. Examples of integration with GLFW, SDL, GLUT, SFML and DirectX are provided. The AntTweakBar library mainly targets graphical applications that need a quick way to tune parameters (even in fullscreen mode) and see the result in real-time like 3D demos, games, prototypes, inline editors, debug facilities of weightier graphical applications, etc. The project is not maintained anymore but feel free to download and modify the source code to fit your needs or fix issues.

Updated emulator of Forgotten Realms: Unlimited Adventures
Dungeon Craft is an adventure creator that emulates the Advanced Dungeons & Dragons Gold Box RPG's released by SSI. Initially designed to be a "more unlimited" version of the Forgotten Realms: Unlimited Adventures (FRUA) game editor and engine, it has far surpassed the capabilities of the old FRUA system. The editor is used to configure art, items, monsters, spells, special abilities, classes and races.. Each adventure is self-contained and doesn't require the editor to be played. The editor is extremely versatile and the databases are completely designer created allowing easy additions and modifications to spells, monsters, items, classes, races and special abilities, and are exportable to be easily shared with others or used in other designs.
