## Download Latest Install

Download and install the latest [ANSYS](namespace_a_n_s_y_s.html "GLTFWriter API Documentation.") suite (21.1 or greater). EnSight (or CEI) products are installed by default.

Most files needed are located within :\[InstallDir\]/vXXX/CEI/ensightXXX/src/readers/dvs (XXX refers to the version number, i.e. 211, 212 etc.)

**Note:** This document will refer to directories and scripts with numbers in them, these values change with versions. In 21.1 the directories/scripts will use 211. For newer versions such as 21.2 replace 211 with 212 etc.

## What is Available

The dvs directory includes all of the code needed to build a C/C++ library to use within another code base as well as some pre-built binaries for C/Python for use on Windows and Linux. Files of Interest:

- [test\_dvs\_client.c](test__dvs__client_8c.html "Test client to exercise the C API of the Dynamic Visualization Store API."): An example of how to use the C API. It's used as our test client.
- [test\_dvs\_client\_cxx.cpp](test__dvs__client__cxx_8cpp.html "Test client to exercise the C++ API of the Dynamic Visualization Store API."): An example of how to use the C++ API. Used in testing.
- [test\_dvs\_client\_simple.py](test__dvs__client__simple_8py.html): An example of how to use the Python API
- [dynamic\_visualization\_store\_api.h](dynamic__visualization__store__api_8h.html "C API for using Dynamic Visualization Store."): This is our exposed C-API
- [dynamic\_visualization\_store\_enums.h](dynamic__visualization__store__enums_8h.html "Contains enums used in C/C++ API."): Enums used in the API
- [dynamic\_visualization\_store\_error\_codes.h](dynamic__visualization__store__error__codes_8h.html "Contains errors used in the DVS C/C++ API."): Error codes returned from API calls
- [dvs\_client\_interface.h](dvs__client__interface_8h.html "C++ Client API for using the Dynamic Visualization Store."): This is our exposed C++ Client API
- [dvs\_server\_interface.h](dvs__server__interface_8h.html "C++ Server API for using Dynamic Visualization Store Server."): This is our exposed C++ Server API

Pre-built Code: If you wish to take advantage of the pre-built C API or C++ API, the built libraries (libdvsapi) are included in the dvs/linux\_2.6\_63 or dvs/win64 directories depending on the platform. For C and C++ you should be able to link against the libdvsapi library and use it directly.

For more information on building the code if you need to please reach out to the Postprocessing team.
