Embree is a collection of high-performance ray tracing kernels. Embree is meant to increase performance of photo-realistic rendering applications.

The Color Transformation Language, or CTL, is a small programming language that was designed to serve as a building block for digital color management systems. CTL allows users to describe color transforms in a concise and unambiguous way by expressing them as programs. In order to apply a given transform to an image, the color management system instructs a CTL interpreter to load and run the CTL program that describes the transform. The original and the transformed image constitute the CTL program's input and output.

This package provides a very basic collection of point, size and rect classes for C++.

OpenCSG is a library for rendering Constructive Solid Geometry (CSG) using OpenGL. CSG is an approach for modeling complex 3D-shapes using simpler ones. For example, two shapes can be combined by uniting them, by intersecting them, or by subtracting one shape from the other.

NanoSVG is a simple single-header SVG parser. The output of the parser is a list of cubic bezier shapes. The library suits well for anything from rendering scalable icons in an editor application to prototyping a game.

OpenEXR provides the specification and reference implementation of the EXR file format. The purpose of EXR format is to accurately and efficiently represent high-dynamic-range scene-linear image data and associated metadata, with strong support for multi-part, multi-channel use cases.

FOX (Free Objects for X) is a C++ based Toolkit for developing Graphical User Interfaces easily and effectively. It offers a wide, and growing, collection of Controls, and provides state of the art facilities such as drag and drop, selection, as well as OpenGL widgets for 3D graphical manipulation. FOX also implements icons, images, and user-convenience features such as status line help, and tooltips. Tooltips may even be used for 3D objects!

ASLI (A Simple Lattice Infiller) is a command-line tool that allows users to fill any 3D geometry with a functionally graded lattice. The lattice infill is constructed out of unit cells, described by implicit functions, whose type, size and feature can be varied locally to obtain the desired local properties.

This package provides a common standard tangent space library used in baking tools to produce normal maps.

POV-Ray is short for the Persistence of Vision Raytracer, a tool for producing high-quality computer graphics. POV-Ray creates three-dimensional, photo-realistic images using a rendering technique called ray-tracing. It reads in a text file containing information describing the objects and lighting in a scene and generates an image of that scene from the view point of a camera also described in the text file. Ray-tracing is not a fast process by any means, but it produces very high quality images with realistic reflections, shading, perspective and other effects.

Discregrid is a C++ library for the parallel discretization of (preferably smooth) functions on regular grids. It generates a (cubic) polynomial discretization given a box-shaped domain, a grid resolution, and a 3D scalar field. The library can also serialize and deserialize the generated discrete grid, and compute and discretize the signed distance field corresponding to a triangle mesh. The following programs are included with Discregrid:

• GenerateSDF: Computes a discrete (cubic) signed distance field from a triangle mesh in OBJ format.

• DiscreteFieldToBitmap: Generates an image in bitmap format of a two-dimensional slice of a previously computed discretization.

• GenerateDensityMap: Generates a density map from a previously generated discrete signed distance field using the cubic spline kernel.

AzPainter is a lightweight full color painting application for editing illustrations and images.

Features include:

• Layers

• Many artistic filters

• Good range of selection tools

• Pen pressure support with automatic brush size adjustment

• Support for 16-bit color images with transparency (RGBA)

• Support for image formats like PSD, PNG, JPEG, TIFF, WebP

SuperFamiconv is a converter for tiled graphics, supporting the graphics formats of the SNES, Game Boy Color and PC Engine game consoles. Automated palette selection is supported.

MMM is a shared memory protocol for virtualising access to framebuffer graphics, audio output and input event.

OpenEXR provides the specification and reference implementation of the EXR file format. The purpose of EXR format is to accurately and efficiently represent high-dynamic-range scene-linear image data and associated metadata, with strong support for multi-part, multi-channel use cases.

AutoTrace is a utility for converting bitmap into vector graphics. It can trace outlines and midlines, effect color reduction or despeckling and has support for many input and output formats. It can be used with the autotrace utility or as a C library, libautotrace.

This is a headers-only library that allows approximate convex decomposition of a 3D surface.

Friction is a versatile motion graphics application that allows you to create vector and raster animations for web and video.

Motion graphics has a wide variety of uses, including:

• Television and film: Title sequences, commercials, and visual effects

• Web design: Animated logos, banners, and interactive elements

• Social media: Animated posts and stories

• Presentations: Animated infographics and slideshows

OpenImageIO is a library for reading and writing images, and a bunch of related classes, utilities, and applications. There is a particular emphasis on formats and functionality used in professional, large-scale animation and visual effects work for film.

MangoHud is a Vulkan and OpenGL overlay for monitoring frames per second (FPS), temperatures, CPU/GPU load and more.

BRDF Explorer is an application that allows the development and analysis of BRDF. It can load and plot analytic BRDF functions (coded as functions in OpenGL's GLSL shader language), measured material data from the MERL database, and anisotropic measured material data from MIT CSAIL. Graphs and visualizations update in real time as parameters are changed, making it a useful tool for evaluating and understanding different BRDFs (and other component functions).

GR is a universal framework for cross-platform visualization applications. It offers developers a compact, portable and consistent graphics library for their programs. Applications range from publication quality 2D graphs to the representation of complex 3D scenes. GR is essentially based on an implementation of a GKS. As a self-contained system it can quickly and easily be integrated into existing applications (i.e. using the ctypes mechanism in Python or ccall in Julia).

PyGraphviz is a Python interface to the Graphviz graph layout and visualization package. With PyGraphviz you can create, edit, read, write, and draw graphs using Python to access the Graphviz graph data structure and layout algorithms.

This package contains tools for building documentation with Sphinx, Graphviz and LaTeX.
