BUILDING FROM SOURCE

1) The pyVolution Visualizer has several dependencies. 

   OpenSceneGraph, OpenThreads, and Producer
            - http://openscenegraph.sourceforge.net
            - available as a bundle, OSG_OP_OT-0.9.7-3
            - this itself has 3rd party dependencies available 
              as a downloadable bundle
            - ensure you can run the examples that come with OSG
              prior to building the viewer

   NetCDF   - a self-describing binary file format I/O library
            - http://my.unidata.ucar.edu/content/software/netcdf/index.html
            - require the header file netcdf.h and the library proper to
              link against

   cppUnit  - a unit testing framework for C++
            - http://cppunit.sourceforge.net
            - this is optional


2) Set environment variables:

   OSG_ROOT :  root of your OpenSceneGraph installation
               conforming to following layout

               OSG_ROOT
                 /OpenThreads
                    /lib
                       /win32 (for VisualStudio builds)
                    /include
                 /Producer
                    /lib
                    /include
                 /OpenSceneGraph
                    /lib
                    /include

   NETCDF_DIR :  root of NetCDF binary package with needed subdirs 
                 /lib and /include

   CPPUNIT :  root of c++ unit testing framework with needed subdirs 
              /lib and /include 


3) For Visual Studio .NET, 

    (i) Open the solution in visualstudio subdir.
   (ii) Open Menu Tools|Options|Projects|VC++Directories and add a
        path to $(NETCDF_DIR)/bin and $(OSG_ROOT)/bin.
  (iii) Build the solution


4) For Mac OSX

    Run make in swwreader and swollen directories.


5) For Linux

    Makefiles not yet written
