    CrystalCMP

    CrystalCMP

    Easy-to-use tool for fast comparison of molecular packing

    CrystalCMP is a code for comparing crystal structures. It is using two basic approaches for this purpose - the fingerprint and the RMSD approach. Result of the comparison is a similarity matrix and dendrogram. Read more here: J. Appl. Cryst. (2016). 49, 2172-2183 (https://doi.org/10.1107/S1600576716016058) and also here: J. Appl. Cryst.

    D-List

    D-List

    An extensive list subsystem, written in C

    D-List is an extensive, production quality, and robust list management subsystem written in C that can be used as a shared library or compiled directly into your project. D-List provides access to 3 classes of lists, and allows extensive manipulation and customization of these lists. D-List lists can also be easily incorporated as primitives into larger treed, or nested data management systems. D-List implements a comprehensive set of linked list primitives that provides multiple forms of both sequential and random element access, bi-directional movement within a list, and an extensive set of list and element manipulation and reordering features. It also provides for an expansive set of user functions that can be added to lists and called automatically, to efficiently implement a broad range of services using the list primitives as underlying technology. It was written primarily for accuracy and speed, and provides extensive debugging support for easy code development.

    PMCGPU

    PMCGPU

    Parallel simulators for Membrane Computing on the GPU

    Membrane Computing is a new research area (within Natural Computing) that aims to provide computing devices abstracted from the functioning and structure of living cells. These devices are called P systems. The objective of this project (PMCGPU) is to bring together all the researchers working on the development of parallel simulators for P systems, specially those using the GPU (e.g. CUDA, OpenCL, etc). Other parallel platforms are also welcome (multicore and manycore, FPGAs, etc). This project has been initiated by the Research Group on Natural Computing (Department of Computer Science and Artificial Intelligence, University of Seville). PMCGPU was born inside the P-Lingua project, of the same research group. PMCGPU is a GNU project, so all the applications developed within it are released under the GPLv3 license. Just contact us if you want to participate. Please, visit the Wiki of the project for further information.

    Quadtree Demo

    Demonstrates a quadtree for spatial indexing of triangles

    This C++ demo allows users to interactively explore a quadtree's behavior. For this purpose the demo uses a quadtree data structure based on axis-aligned bounding boxes to speed up the search for triangles in a mesh. Depending on a search point all triangles of a quadtree's region are retrieved and relevant information about the search is shown. Quadtree creation can be parametrized by three parameters: - Maximum tree depth. - Maximum number of triangles per region. - Percentage of total number of triangles per region. The OpenGL graphics library is used to render the results, regions as well as the underlying triangle mesh. Navigation (e.g. zooming, moving) is available by keyboard and mouse. Example meshes are provided in wavefront *.obj format and can be opened from inside the program.

    Dynamic Arrays and Hashes (Delphi, C++)

    Very fast classes for working with Dynamic Arrays in Delphi and C++

    (New version 1.04 is released) Dynamic Arrays is a set of useful very fast classes for data manipulating in memory. Flexible memory control, functionality that standard containers do not have, fast operations (assembler implementation for x86 and x64 platforms). Available for Delphi all latest versions and for C++. Powerful Hash and Double Hash classes to work with pairs of values (key and value) and with values that have two keys (key1, key2, value). Give it a try and let me know how it works.

    PdfPageCounter

    C++ code to count the number pages in a given PDF file.

    This C++ library contains the 'PdfPageCount' class that performs the single task of finding the number of pages in a given PDF document. While the PdfPageCount class is very simple to use, the contained code is complex because the page count can be hidden in any number of places, quite often within compressed data.
