A vtk reader for the FITS data format. A very simple class that relies on the CFITSIO library to do most of the work.

Source code:
vtkFitsReader.h
vtkFitsReader.cxx

Examples:
example Tcl script - to use this you will need to build the vtk Tcl/Tk interpreter with the vtkFitsReader source in the contrib/ directory.
example C++ program and Makefile - need to compile cfitsio library and vtk library first.
OMC.fits - sample data file.
