PVLIB 1.0 Library Description                     6/22/92
-----------------------------


Purpose
-------
PVLIB  was created to provide a standard set of C  library  func-
tions to simplify coding of programs which create scene files for 
DKB Trace and/or POV Trace.  


Description
-----------
The PVLIB library was written in Microsoft C.  However the source 
should  be straight ANSI C, and you should be able to create  the 
library for other compilers with the source provided.


Usage
-----
Refer  to  the file PVLIB.REF for data  structures  and  function 
descriptions.   No  data is passed directly to  PVLIB  functions, 
data  structures  are used to provide variables utilized  by  the 
main  program and the PVLIB functions.  A sample program  is  in-
cluded  which (hopefully) illustrates the use of pointers to  the 
PVLIB  data  structures.   Also,  the  PVGEN  program  (look  for 
PVGEN10.ZIP on this BBS) utilizes the PVLIB library, and examina-
tion of the code might be helpful.


Copyright
---------
PVLIB  is copyrighted, however permission to freely use  the  li-
brary  is given.  Please include a copyright notice in  any  pro-

If  you  find  the PVLIB library to be of  use,  please  consider

wife,  maybe  she'll be more lenient with  allowing  me  computer 
time!
