The mesa-utils package contains several utility tools for Mesa: eglinfo, glxdemo, glxgears, glxheads, and glxinfo.

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.

glmark2 is an OpenGL 2.0 and OpenGL ES 2.0 benchmark based on the original glmark benchmark by Ben Smith.

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.

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

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.

libopenglrecorder is a library allowing optional async readback OpenGL frame buffer with optional audio recording. It will do video and audio encoding together.

This is the last version of the mojoshader library with the glProgramViewportFlip before it was replaced with glProgramViewportInfo.

Glad uses the official Khronos XML specifications to generate a GL/GLES/EGL/GLX/WGL loader tailored for specific requirements.

Piglit is a collection of automated tests for OpenGL and OpenCL implementations.

MojoShader is a library to work with Direct3D shaders on alternate 3D APIs and non-Windows platforms. The primary motivation is moving shaders to OpenGL languages on the fly. The developer deals with "profiles" that represent various target languages, such as GLSL or ARB_*_program.

This allows a developer to manage one set of shaders, presumably written in Direct3D HLSL, and use them across multiple rendering backends. This also means that the developer only has to worry about one (offline) compiler to manage program complexity, while MojoShader itself deals with the reduced complexity of the bytecode at runtime.

MojoShader provides both a simple API to convert bytecode to various profiles, and (optionally) basic glue to rendering APIs to abstract the management of the shaders at runtime.

A small little utility to run a couple of executables under a new DBus session for testing.

sdbus-c++ is a high-level C++ D-Bus library designed to provide easy-to-use yet powerful API in modern C++. It adds another layer of abstraction on top of sd-bus, the C D-Bus implementation by systemd.

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.

Telepathy is a flexible, modular communications framework that enables real-time communication over D-Bus via pluggable protocol backends. Telepathy is a communications service that can be accessed by many applications simultaneously.

This package provides the library for GLib applications.

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.

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

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

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

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.

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.

Python bindings for GLib, GObject, and GIO.
