Libmypaint, also called "brushlib", is a library for making brushstrokes which is used by MyPaint and GIMP.

GIMP is an application for image manipulation tasks such as photo retouching, composition and authoring. It supports all common image formats as well as specialized ones. It features a highly customizable interface that is extensible via a plugin system.

Babl is a dynamic, any-to-any pixel format translation library. It allows converting between different methods of storing pixels, known as pixel formats, that have different bit depths and other data representations, color models, and component permutations.

A vocabulary to formulate new pixel formats from existing primitives is provided, as well as a framework to add new color models and data types.

This package provides resynthesizer plugins for GIMP, which encompasses tools for healing selections (content-aware fill), enlarging the canvas and healing the border, increasing the resolution while adding detail, and transferring the style of an image.

This package provides a simple plug-in to apply the fourier transform on an image, allowing you to work with the transformed image inside GIMP. You can draw or apply filters in fourier space and get the modified image with an inverse fourier transform.

GEGL (Generic Graphics Library) provides infrastructure to do demand based cached non destructive image editing on larger than RAM buffers.

Poly2Tri-C is a library for generating, refining and rendering 2-Dimensional Constrained Delaunay Triangulations.

GKrellM is a single process stack of system monitors which supports applying themes to match its appearance to your window manager, Gtk, or any other theme.

GL2PS is a C library providing high quality vector output for any OpenGL application. GL2PS uses sorting algorithms capable of handling intersecting and stretched polygons, as well as non-manifold objects. GL2PS provides many features including advanced smooth shading and text rendering, culling of invisible primitives and mixed vector/bitmap output.

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.

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

SOIL is a tiny C library used primarily for uploading textures into OpenGL.

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

A library for handling OpenGL function pointer management.

VirtualGL redirects the 3D rendering commands from OpenGL applications to 3D accelerator hardware in a dedicated server and displays the rendered output interactively to a thin client located elsewhere on the network.

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.

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.
