libglvnd is a vendor-neutral dispatch layer for arbitrating OpenGL API calls between multiple vendors. It allows multiple drivers from different vendors to coexist on the same file system, and determines which vendor to dispatch each API call to at runtime.

Both GLX and EGL are supported, in any combination with OpenGL and OpenGL ES.

GLU, or OpenGL Utility Library provides some higher-level functionality not provided by just OpenGL itself. Some of GLU's Features include: Scaling of 2D images and creation of mipmap pyramids, Transformation of object coordinates into device coordinates and vice versa, Support for NURBS surfaces, Support for tessellation of concave or bow tie polygonal primitives, Specialty transformation matrices for creating perspective and orthographic projections, positioning a camera, and selection/picking, Rendering of disk, cylinder, and sphere primitives, Interpreting OpenGL error values as ASCII text.

S2TC is a patent-free implementation of S3 Texture Compression (S3TC, also known as DXTn or DXTC) for Mesa.

Mesa is a free implementation of the OpenGL and Vulkan specifications - systems for rendering interactive 3D graphics. A variety of device drivers allows Mesa to be used in many different environments ranging from software emulation to complete hardware acceleration for modern GPUs.

NanoVG is an antialiased vector graphics rendering library for OpenGL. It is aimed for building scalable user interfaces and visualizations.

GLFW is a library for OpenGL, OpenGL ES and Vulkan development for desktop computers. It provides a simple API for creating windows, contexts and surfaces, receiving input and events.

Freeglut is a completely Free/OpenSourced alternative to the OpenGL Utility Toolkit (GLUT) library. GLUT was originally written by Mark Kilgard to support the sample programs in the second edition OpenGL RedBook. Since then, GLUT has been used in a wide variety of practical applications because it is simple, widely available and highly portable.

GLUT (and hence freeglut) allows the user to create and manage windows containing OpenGL contexts on a wide range of platforms and also read the mouse, keyboard and joystick functions. Freeglut is released under the X-Consortium license.

Guile-OpenGL is a library for Guile that provides bindings to the OpenGL graphics API.

Waffle is a library that allows one to defer selection of an OpenGL API and a window system until runtime.

D-Bus is a message bus system, a simple way for applications to talk to one another. In addition to interprocess communication, D-Bus helps coordinate process lifecycle; it makes it simple and reliable to code a "single instance" application or daemon, and to launch applications and daemons on demand when their services are needed.

D-Bus supplies both a system daemon (for events such as "new hardware device added" or "printer queue changed") and a per-user-login-session daemon (for general IPC needs among user applications). Also, the message bus is built on top of a general one-to-one message passing framework, which can be used by any two apps to communicate directly (without going through the message bus daemon). Currently the communicating applications are on one computer, or through unencrypted TCP/IP suitable for use behind a firewall with shared NFS home directories.

Glibmm provides a C++ programming interface to the part of GLib that are useful for C++.

This variant D-Bus package is built with verbose mode, which eases debugging of D-Bus services by printing various debug information when the DBUS_VERBOSE environment variable is set to 1. For more information, refer to the dbus-daemon(1) man page.

Net::DBus provides a Perl XS API to the DBus inter-application messaging system. The Perl API covers the core base level of the DBus APIs, not concerning itself yet with the GLib or QT wrappers.

Dbus-cxx is a C++ wrapper for dbus.

It exposes the C API to allow direct manipulation and relies on sigc++ to provide an Oriented Object interface.

This package provide 2 utils:

1. dbus-cxx-xml2cpp to generate proxy and adapter

2. dbus-cxx-introspect to introspect a dbus interface

Some codes examples can be find at: https://dbus-cxx.github.io/examples.html

This module provides perl access to GLib and GLib's GObject libraries. GLib is a portability and utility library; GObject provides a generic type system with inheritance and a powerful signal system. Together these libraries are used as the foundation for many of the libraries that make up the Gnome environment, and are used in many unrelated projects.

Libsigc++ implements a type-safe callback system for standard C++. It allows you to define signals and to connect those signals to any callback function, either global or a member function, regardless of whether it is static or virtual. It also contains adaptor classes for connection of dissimilar callbacks and has an ease of use unmatched by other C++ callback libraries.

Template-GLib is a library to help you generate text based on a template and user defined state. Template-GLib does not use a language runtime, so it is safe to use from any GObject-Introspectable language.

Template-GLib allows you to access properties on GObjects as well as call simple methods via GObject-Introspection.

GObject introspection is a middleware layer between C libraries (using GObject) and language bindings. The C library can be scanned at compile time and generate metadata files, in addition to the actual native C library. Then language bindings can read this metadata and automatically provide bindings to call into the C library.

It allows you to define signals and to connect those signals to any callback function, either global or a member function, regardless of whether it is static or virtual.

GLib bindings for D-Bus. The package is obsolete and superseded by GDBus included in Glib.

This library provides objects and helper methods to help reading and writing AppStream metadata.

cppgir processes .gir files derived from GObject introspection annotations into a set of C++ files defining suitable namespaces, classes and other types that together form a C++ binding.
