NAME

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 contains 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; application-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.
