Even though there are many wrappers/porting of the VTK source !> code (C++ code), there is not a Fortran one. This library is not a porting or a wrapper of the VTK code, !> but it only an exporter/importer of the VTK data format written in pure Fortran language (standard Fortran 2003) !> that can be used by Fortran coders (yes, there are still a lot of these brave coders...) without mixing Fortran with !> C++ language. Fortran is still the best language for high performance computing for scientific purpose, like CFD !> computing. It is necessary a tool to deal with VTK standard directly by Fortran code. The library was made to fill !> this empty: it is a simple Fortran module able to export native Fortran data into VTK data format and to import VTK !> data into a Fortran code, both in ascii and binary file format. !> !> The library provides an automatic way to deal with VTK data format: all the formatting processes is nested into the !> library and users communicate with it by a simple API passing only native Fortran data (native Fortran scalar, vector !> and matrix). !> !> The library is still in developing and testing, this is first usable release, but there are not all the features of !> the stable release (the importer is totally absent and the exporter is not complete). Surely there are a lot of bugs !> and the programming style is not the best, but the exporters are far-complete. !> !> The supported VTK features are: !> - Exporters: !> - Legacy standard: !> - Structured Points; !> - Structured Grid; !> - Unstructured Grid; !> - Polydata (\b missing); !> - Rectilinear Grid; !> - Field (\b missing); !> - XML standard: !> - serial dataset: !> - Image Data (\b missing); !> - Polydata (\b missing); !> - Rectilinear Grid; !> - Structured Grid; !> - Unstructured Grid; !> - parallel (partitioned) dataset: !> - Image Data (\b missing); !> - Polydata (\b missing); !> - Rectilinear Grid; !> - Structured Grid; !> - Unstructured Grid; !> - composite dataset: !> - vtkMultiBlockDataSet; !> - Importers are \b missing. !> !> @libvtk can handle multiple concurrent files and it is \b thread/processor-safe (meaning that can be safely used into !> parallel frameworks as OpenMP or MPI). !> !> The library is an open source project, it is distributed under the GPL v3. Anyone is interest to use, to develop or !> to contribute to @libvtk is welcome. !> !> It can be found at: https://github.com/szaghi/Lib_VTK_IO !> !> @par VTK_Standard !> VTK, Visualization Toolkit, is an open source software that provides a powerful framework for the computer graphic, for !> the images processing and for 3D rendering. It is widely used in the world and so it has a very large community of users, !> besides the Kitware (The Kitware homepage can be found here: http://public.kitware.com) company provides professional !> support. The toolkit is written in C++ and a lot of porting/wrappers for Tcl/Tk, Java and Python are provided, unlucky !> there aren't wrappers for Fortran. !> !> Because of its good features the VTK toolkit has been used to develop a large set of open source programs. For my work !> the most important family of programs is the scientific visualization programs. A lot of high-quality scientific !> visualization tool are available on the web but for me the best is ParaView: I think that it is one of the best !> scientific visualization program in the world and it is open source! Paraview is based on VTK. !> @par Paraview !> ParaView (The ParaView homepage can be found here: http://www.paraview.org) is an open source software voted to scientific !> visualization and able to use the power of parallel architectures. It has an architecture client-server in order to make !> easy the remote visualization of very large set of data. Because it is based on VTK it inherits all VTK features. ParaView !> is very useful for Computational Fluid Dynamics visualizations because it provides powerful post-processing tools, it !> provides a very large set of importers for the most used format like Plot3D and HDF (the list is very large). It is easy to !> extend ParaView because it supports all the scripting language supported by VTK. !> @note All the @libvtk functions are I4P integer functions: the returned integer output is 0 if the function calling has !> been completed right while it is >0 if some errors occur (the error handling is only at its embryonic phase). Therefore the !> functions calling must be done in the following way: \n !> @code !> ... !> integer(I4P):: E_IO !> ... !> E_IO = VTK_INI(.... !> ... @endcode !> @libvtk programming style is based on two main principles: portable kind-precision of reals and integers !> variables and dynamic dispatching. Using dynamic dispatching @libvtk has a simple API. The user calls !> a generic procedure (VTK_INI, VTK_GEO,...) and the library, depending on the type and number of the inputs passed, calls the !> correct internal function (i.e. VTK_GEO for R8P real type if the input passed is R8P real type). By this interface only few !> functions are used without the necessity of calling a different function for every different inputs type. !> Dynamic dispatching is based on the internal kind-precision selecting convention: Fortran 90/95 standard has introduced some !> useful functions to achieve the portability of reals and integers precision and @libvtk uses these functions to define portable !> kind-precision; to this aim @libvtk uses IR_Precision module. !> @author Stefano Zaghi !> @version 1.1 !> @date 2013-04-26 !> @par News !> - Correct bug affecting binary output; !> - implement concurrent multiple files IO capability; !> - implement FieldData tag for XML files, useful for tagging dataset with global auxiliary data, e.g. time, time step, ecc; !> - implement Parallel (Partitioned) XML files support (.pvtu,.pvts,.pvtr); !> - implement Driver testing program for providing practical examples of @libvtk usage; !> - added support for parallel framework, namely OpenMP (thread-safe) and MPI (process-safe). !> @copyright GNU Public License version 3. !> @note The supported compilers are GNU gfortran 4.7.x (or higher) and Intel Fortran 12.x (or higher). @libvtk needs a modern !> compiler providing support for some Fortran standard 2003 features. !> @todo \b CompleteExporter: Complete the exporters !> @todo \b CompleteImporter: Complete the importers !> @todo \b DocExamples: Complete the documentation of examples !> @todo \b g95_test: Test g95 compiler !> @bug Array-Reshape: \n Fortran allows automatic reshape of arrays, e.g. 2D array can be automatically (in the !> function calling) transformed to a 1D array with the same number of element of 2D array. The use of !> dynamic dispatching for @libvtk functions by means of generic interfaces had disable this feature: !> dynamic dispatching use the array-shape information to detect, at compile-time, !> the correct function to be called inside the generic interface functions. Thus automatic reshaping !> of arrays at calling function phase is not allowed. \n !> Instead an explicit reshape can be used by means of the Fortran built-in function \em reshape. !> As an example considering a call to the generic function \em VTK_VAR_XML an explicit array reshape !> could be: \n \n !> E_IO = VTK_VAR_XML(NC_NN=nn,varname='u',var=\b reshape(u(ni1:ni2,nj1:nj2,nk1:nk2),(/nn/))) \n \n !> where built in function \em reshape has explicitly being used in the calling to VTK_VAR_XML. !> @bug XML-Efficiency: \n This is not properly a bug. There is an inefficiency when saving XML binary file. To write XML !> binary @libvtk uses a temporary scratch file to save binary data while saving all formatting data to !> the final XML file. Only when all XML formatting data have been written the scratch file is rewind !> and the binary data is saved in the final tag of XML file as \b raw data.
