    Matplot++

    Matplot++

    Matplot++: A C++ Graphics Library for Data Visualization

    Data visualization can help programmers and scientists identify trends in their data and efficiently communicate these results with their peers. Modern C++ is being used for a variety of scientific applications, and this environment can benefit considerably from graphics libraries that attend the typical design goals toward scientific data visualization. Besides the option of exporting results to other environments, the customary alternatives in C++ are either non-dedicated libraries that depend on existing user interfaces or bindings to other languages. Matplot++ is a graphics library for data visualization that provides interactive plotting, means for exporting plots in high-quality formats for scientific publications, a compact syntax consistent with similar libraries, dozens of plot categories with specialized algorithms, multiple coding styles, and supports generic backends.

    SimpleXlsxWriter

    C++ library for creating XLSX files for MS Excel 2007 and above.

    This library represents XLSX files writer for Microsoft Excel 2007 and above. The main feature of this library is that it uses C++ standard file streams. On the one hand it results in almost unnoticeable memory and CPU resources consumption while processing (that may be very useful at saving a large data arrays), but on the other hand it makes unfeasible to edit data that were written. Hence, if using this library the structure of the future report should be known enough. The library is written in C++ with using STL functionality and based on the ZIP library (included), which has a free license: http://www.codeproject.com/Articles/7530/Zip-Utils-clean-elegant-simple-C-Win32 This library is distributed under the terms of the zlib license: http://www.zlib.net/zlib_license.html

    New CTruck3D Rally

    Free-roaming 3D racing game featuring advanced terrain rendering

    It's a free-roaming 3D racing game featuring advanced terrain rendering. For small file-size, a 4k x 4k terrain is available, sampled meter-by-meter so it's very smooth. Lightweight program. This is the form in which I wished to do the first release of the terrain rendering Algorithm I have developed throughout almost 2 years. Written in C++, featuring multithreading (2 threads): a total remake of the first 3D game I did years ago, CTruck3D_Simplex and sequels. This works better, thought the basic idea is the seme. Similar to the old games Terep2 and "1nsane". I am an algorithmist, not a game developer: so it was hard for me to put this togather. But I did this tribute to videogames. Have lots of fun!
