Data formats

Below are most of data formats that I have dealt with for scientific visualization.

• VTK [Wikipedia]
  The Visualization Toolkit(VTK) is an open-source software system for 3D computer graphics and visualization.
  
  
• OpenDX [Wikipedia]
  It is an open-source visualization software package based on IBM's visualization data explorer.
  
  
• NetCDF (Network Common Data Form) [Wikipedia]
  According the Wikipedia NetCDF page, it is a set of software libraries and self-describing, machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data.
• Reading NetCDF files in MATLAB and Analyzing the Precipitation Data
  
  
• Silo [Wikipedia]
  Silo is a computer data format and library for storing rectilinear, curvilinear, unstructured, or point meshes in 2D and 3D. It is on top of other low-level storage libraries such as PDB, NetCDF, HDF5. Silo example codes are available at http://www.e-science.le.ac.uk/format/silocode.shtml.
