facedetect is a face detector for batch processing. It answers the question: "Is there a face in this image?" and gives back either an exit code or the coordinates of each detect face in the standard output. facedetect is used in software such as fgallery to improve the thumbnail cutting region, so that faces are always centered.

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!

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).

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.

F3D (pronounced /fɛd/) is a VTK-based 3D viewer with simple interaction mechanisms and which is fully controllable using arguments on the command line. It supports a range of file formats (including animated glTF, STL, STEP, PLY, OBJ, FBX), and provides numerous rendering and texturing options.

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.

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.

OpenSubdiv is a set of libraries that implement high performance subdivision surface (subdiv) evaluation on massively parallel CPU and GPU architectures.

When a GPU renders triangle meshes, various stages of the GPU pipeline have to process vertex and index data. The efficiency of these stages depends on the data you feed them; this library provides algorithms to help optimize meshes for these stages, as well as algorithms to reduce the mesh complexity and storage overhead.

2geom is a C++ library of mathematics for paths, curves, and other geometric calculations. Designed for vector graphics, it tackles Bézier curves, conic sections, paths, intersections, transformations, and basic geometries.

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).

This package contains the Tachyon raytracer. It supports the typical ray tracer features, most of the common geometric primitives, shading and texturing modes, etc. It also supports less common features such as HDR image output, ambient occlusion lighting, and support for various triangle mesh and volumetric texture formats beneficial for molecular visualization.
