...Some parts of the 3D engine, like the animated bump mapping, are still waiting to be ported to my newer 3D project, GLOBE_3D !... DOS and Linux versions available. Remarks for the DOS version: It is also a funny example of a game system almost fully in Ada, including sound driver, graphics driver, keyboard driver. The only things not in Ada there are the file system (MS-DOS), the 32-bit DOS extender (CWSDPMI) and the mouse driver. For running, I recommend DOSBox. For building from sources, you'll need the DJGPP compiler, which contains a version of GNAT - seems to be still updated as in June 2016 ! ...

The Hungarian algorithm can be described as optimally solving a workers versus jobs assignment problem that minimizes total cost. This implementation assumes a square cost matrix, i.e. the number of jobs equals the number of workers to do them.

AdaGate is a 3D OpenGL strategy game with escape rooms in a Stargate fantasy setting. It is an elaborate example of modern OpenGL programming using the Ada language; and a tribute to Narbacular Drop, and Amelia Earhart. Each room has a barrier that must be circumvented using portals. The barriers include water with piranha, molten magma, and walls. Runs on Windows, OSX, and GNU/Linux. The linux binary now runs on many linux distros!

This example uses a recursive procedure to capture directory information into an Ada 2012 multiway tree then displays the path and name of each directory item. The directory information is contained in a directory node object. The project was developed using GNAT Studio (GPS) in Windows 10.

Ada Fonts is a minimalistic example of using freetype fonts in OpenGL Ada applications using Felix Krause's FreeTypeAda package It is intended to be the modern version of the "glut font" demos from a previous era. It also uses Stephen Sangwine's PNG-IO package, and thin bindings to OpenGL, SDL2. More importantly, it shows how to encapsulate the scripts and runtime libraries necessary to easily compile and run on any computer running Windows, OS-X, or GNU/Linux. ...

...GNAT Util GPL 2013 contains components from the GNAT GPL 2013 compiler. At least for ASIS, the components used to build it must match the components in the compiler, so if building ASIS for use with (for example) FSF GCC 4.8.0 a version of GNAT Util is needed which contains components from FSF GCC 4.8.0. This project provides such a library. The code is released under GPL V3.0 without any Runtime Exception, because the compiler components are themselves pure GPL. NOTE: This library was written to support building Ada tools for Darwin (Mac OS X), and contains Darwin-specific choices.

The VSR is a repository of tools and challenges in verification (see for example epubs.cclrc.ac.uk/work-details?w=33971). It is part of the international grand challenge on software verification (eg http://vstte.ethz.ch/pdfs/vstte-hoare-misra.pdf)
