VolPack - introduction to VolPack, a library for volume rendering

       Source  code  and  documentation  for  VolPack  are  available  free  via the World Wide Web (http://www-
       graphics.stanford.edu/software/volpack) or by anonymous ftp (ftp://graphics.stanford.edu/pub/volpack).

       The following data types are declared in the VolPack header file (volpack.h):

       vpContext
              An  opaque  handle for a rendering context.  A context contains all of the information required to
              render a volume, including classification and  shading  parameters,  the  view  transformation,  a
              description  of  the  format of the volume data, and private data structures used by the rendering
              routines.

       vpResult
              A result code.  Most of the library routines return the code VP_OK upon successful completion,  or
              an error code if the library call fails.

       vpVector3
              A three-element linear array of double-precision elements (double[3]).

       vpVector4
              A four-element linear array of double-precisions elements (double[4]).

       vpMatrix3
              A three-by-three array of double-precision elements (double[3][3]).

       vpMatrix4
              A four-by-four array of double-precision elements (double[4][4]).

       VolPack  is a portable software library for volume rendering.  It is based on a new family of fast volume
       rendering algorithms (see Philippe Lacroute and Marc Levoy, Fast  Volume  Rendering  Using  a  Shear-Warp
       Factorization  of the Viewing Transformation, Proc. SIGGRAPH '94, in ComputerGraphics, Annual Conference
       Series, 1994, pp. 451-458).  For a tutorial introduction to the library see the VolPackUser'sGuide.
