# Context(3)

create/destroy a rendering context

## 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 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.
