Encapsulates a VRML <a class="el" href="classopenvrml_1_1browser.html" title="Encapsulates a VRML browser.">browser</a>.
<p>
<code><a class="el" href="classopenvrml_1_1browser.html" title="Encapsulates a VRML browser.">browser</a></code> is the foundation of the OpenVRML runtime. <code><a class="el" href="classopenvrml_1_1browser.html" title="Encapsulates a VRML browser.">browser</a></code> is instantiated with an implementation of <code><a class="el" href="classopenvrml_1_1resource__fetcher.html" title="An abstract factory for resource_istreams.">resource_fetcher</a></code>, which is provided by application code. The <code><a class="el" href="classopenvrml_1_1resource__fetcher.html" title="An abstract factory for resource_istreams.">resource_fetcher</a></code> instance must have a longer lifetime than the <code><a class="el" href="classopenvrml_1_1browser.html" title="Encapsulates a VRML browser.">browser</a></code> instance, since the <code><a class="el" href="classopenvrml_1_1resource__fetcher.html" title="An abstract factory for resource_istreams.">resource_fetcher</a></code> instance could be used during destruction of the <code><a class="el" href="classopenvrml_1_1browser.html" title="Encapsulates a VRML browser.">browser</a></code>. Note, however, that <code><a class="el" href="classopenvrml_1_1browser.html" title="Encapsulates a VRML browser.">browser</a></code>'s destructor will block until all threads that may use the <code><a class="el" href="classopenvrml_1_1resource__fetcher.html" title="An abstract factory for resource_istreams.">resource_fetcher</a></code> have completed. So it is sufficient to have the <code><a class="el" href="classopenvrml_1_1browser.html" title="Encapsulates a VRML browser.">browser</a></code> and the <code><a class="el" href="classopenvrml_1_1resource__fetcher.html" title="An abstract factory for resource_istreams.">resource_fetcher</a></code> destroyed sequentially in the same thread.<p>

The invariant is that if a <code><a class="el" href="classopenvrml_1_1node.html" title="A node in the scene graph.">node</a></code>'s bounding volume is out of date, then the bounding volumes of all that <code><a class="el" href="classopenvrml_1_1node.html" title="A node in the scene graph.">node</a></code>'s ancestors must be out of date.
