vpCreateContext(3)	   Library Functions Manual	    vpCreateContext(3)

NAME
       vpCreateContext,	vpDestroyContext - create/destroy a rendering context

SYNOPSIS
       #include	<volpack.h>

       vpContext *
       vpCreateContext()

       void
       vpDestroyContext(vpc)
	   vpContext *vpc;

ARGUMENTS
       vpc    VolPack context from vpCreateContext.

DESCRIPTION
       vpCreateContext	returns	a handle for a new rendering context.  It con-
       tains default values for	most of	the rendering parameters.

       vpDestroyContext	destroys a rendering context and frees the  associated
       memory.	 Only  data structures allocated by the	library	are freed; ap-
       plication-defined data structures that are referenced in	the  rendering
       context through a pointer are not freed (e.g. arrays of volume data and
       shading	lookup	tables).   The	application is responsible for keeping
       track of	such data structures and freeing them when appropriate.
