Description:Visualization Interface for Virtual Observatory
Abstract:VisIVO Server (pre-alpha version) is a spin-off of VisIVO. VisIVO Server can create a 3D view of data tables. It will run on each Linux based system. The main characteristic is that VisIVO Server gives support for huge data. No limits (in principle) are fixed to visualize your data. Some limits exist up to now, but the next version will solve these problems. The FITS and HDF5 data format will be included among supported formats. Output data from Gadget code will be soon supported. The project will be completed in December 2008 <br>
VisIVO Server runs in a grid environment (VisIVO GRID). The grid we use is the Cometa Consortium grid (PI2S2 project).This procedure allows the user to create 3D views of data produced during a run in the grid environment or stored in the grid catalogue. The submission of a jdl file command containing the script to start VisIVO Server will allow us to automatically create 3D png images of data, that can be downloaded in the Output Sandbox or saved in the Grid catalogue.
Demo scripting shell and executables for the Cometa PI2S2 worker node can be downloaded in the VisIVO home page. Demo Data are also available in the Cometa Grid catalogue.
VisIVO Server will be installed in the WNs of the Cometa grid, but can also be sent in the Input Sandbox.

It convert the following data format without limits on data dimension:
<br>ASCII tables are expected to be in tabular format. The table can contain N variables organized in columns.
<br>CSV is a delimited data format that has fields/columns separated by the comma character and records/rows separated by newlines. The CSV file format does not require a specific character encoding, byte order, or line terminator format.
<br>You must give two files.
<br>A header file called filename.bin.head that contains basic metadata, and the binary file calle
