PolyView
========
(1) What does it do?
NCSA PolyView displays an HDF Vset of polygons or points at a two
or three dimensional, interactive image with optional annotation,
which may be written to a RIS8 HDF format file. The program
also allows you to:
-- change display projection
-- render display as points, lines, or polygons
-- choose constant or gouraud shaded polygons
-- load and manipulate the colormap
-- animate a series of vdata sets
-- view a fly-by of the data using a script file
(2) New Features of NCSA PolyView 2.0
--keyboard-command interface
--automated creation of scripts
--dialog windows
--multiple windows and datasets in one session
--object hierarchies
--picking and querying of objects, polygonal faces, and vertices
--support for NCSA's Data Transfer Mechanism (DTM)
(2) How is it used?
The program reads HDF Vset files. The HDF Vset 2.0 library
is required. The necessary code for this application is included
in this release.
(3) Where does it run?
PolyView is only supported on the Silicon Graphics Personal
IRIS 4D/20G (24-bit color, 24-bit Z-buffer). It makes extensive
use of Z-buffering. Although it has not been tested on higher-end
IRISes, it should run on most models. It is compiled using
shared graphics and mathematics libraries.
(4) How can I get it?
(a) Obtaining PolyView using anonymous ftp
Login to zaphod.ncsa.uiuc.edu (141.142.20.50), with a login
name of "anonymous". Give your real name as password. Move
to the directory "polyview" by issuing the command
"cd UNIX/PolyView/PolyView2.0".

(b) By remote login
If you have an account on the NCSA Suns, you may download HDF
Vset in this way. Login to zaphod.ncsa.uiuc.edu, cd to the
directory /sdg/ftp/polyview and copy all files in that
directory.
(5) Documentation
ASCII and Microsoft Word documentation are available.
A bound, laser-printed copy of the document complete with
illustrations may be obtained by contacting the following address.

(6) Files
In order to create the example HDF Vset file, "demo.hdf", you
should download the following files:
makefile md.c df.h dfi.h vg.h libdf.a libvg.a
The makefile will compile "md" which, in turn, is used to create
"demo.hdf". "md.c" provides example code for creating an HDF
Vset file from scratch, and may be used as a starting point for
a data filter.
Creating PolyView itself requires all of the files in the
v2/src directory. Typing "make" without any parameters is
all that is necessary to create the program.
(7) Related Items
For further development of Vset files it is recommended that you
obtain the HDF Vset 2.1 code. It is available via anonymous ftp,
by remote login, or direct from NCSA on tape.
