GodSVG is a structured WYSIWYG SVG editor allowing image editing and source editing simultaneously.

Coin is a 3D graphics library with an Application Programming Interface based on the Open Inventor 2.1 API. For those who are not familiar with Open Inventor, it is a scene-graph based retain-mode rendering and model interaction library, written in C++, which has become the de facto standard graphics library for 3D visualization and visual simulation software in the scientific and engineering community.

Open Shading Language (OSL) is a language for programmable shading in advanced renderers and other applications, ideal for describing materials, lights, displacement, and pattern generation.

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).

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!

IlmBase provides several utility libraries for C++. Half is a class that encapsulates ILM's 16-bit floating-point format. IlmThread is a thread abstraction. Imath implements 2D and 3D vectors, 3x3 and 4x4 matrices, quaternions and other useful 2D and 3D math functions. Iex is an exception-handling library.

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.
