<DD>Removes all Locales and their associates branch graphs from
 this universe.  All branch graphs within each Locale are
 detached, regardless of whether their ALLOW_DETACH capability
 bits are set.  Each Locale is then marked as being dead: no
 branch graphs may subsequently be attached.  This method
 should be called by applications and applets to allow
 Java 3D to cleanup its resources.

<A NAME="getProperties()"><!-- --></A><H3>
getProperties</H3>
<PRE>
public static final java.util.Map <B>getProperties</B>()</PRE>
<DL>
<DD>Returns a read-only Map object containing key-value pairs that
 define various global properties for Java 3D.  All of the keys
 are String objects.  The values are key-specific, but most will
 be String objects.

 <p>
 The set of global Java 3D properties always includes values for
 the following keys:

 <p>
 <ul>
 <table BORDER=1 CELLSPACING=1 CELLPADDING=1>
 <tr>
 <td><b>Key (String)</b></td>
 <td><b>Value Type</b></td>
 </tr>
 <tr>
 <td><code>j3d.version</code></td>
 <td>String</td>
 </tr>
 <tr>
 <td><code>j3d.vendor</code></td>
 <td>String</td>
 </tr>
 <tr>
 <td><code>j3d.specification.version</code></td>
 <td>String</td>
 </tr>
 <tr>
 <td><code>j3d.specification.vendor</code></td>
 <td>String</td>
 </tr>
 <tr>
 <td><code>j3d.renderer</code></td>
 <td>String</td>
 </tr>
 </table>
 </ul>

 <p>
 The descriptions of the values returned for each key are as follows:

 <p>
 <ul>

 <li>
 <code>j3d.version</code>
 <ul>
 A String that defines the Java 3D implementation version.
 The portion of the implementation version string before the first
 space must adhere to one of the the following three formats
 (anything after the first space is an optional free-form addendum
 to the version):
 <ul>
 <i>x</i>.<i>y</i>.<i>z</i><br>
 <i>x</i>.<i>y</i>.<i>z</i>_<i>p</i><br>
 <i>x</i>.<i>y</i>.<i>z</i>-<i>ssss</i><br>
 </ul>
 where:
 <ul>
 <i>x</i> is the major version number<br>
 <i>y</i> is the minor version number<br>
 <i>z</i> is the sub-minor version number<br>
 <i>p</i> is the patch revision number <br>
 <i>ssss</i> is a string, identifying a non-release build
 (e.g., beta1, build47, rc1, etc.).  It may only
 contain letters, numbers, periods, dashes, or
 underscores.
 </ul>
 </ul>
 </li>
 <p>

 <li>
 <code>j3d.vendor</code>
 <ul>
 String that specifies the Java 3D implementation vendor.
 </ul>
 </li>
 <p>

 <li>
 <code>j3d.specification.version</code>
 <ul>
 A String that defines the Java 3D specification version.
 This string must be of the following form:
 <ul>
 <i>x</i>.<i>y</i>
 </ul>
 where:
 <ul>
 <i>x</i> is the major version number<br>
 <i>y</i> is the minor version number<br>
 </ul>
 No other characters are allowed in the specification version string.
 </ul>
 </li>
 <p>

 <li>
 <code>j3d.specification.vendor</code>
 <ul>
 String that specifies the Java 3D specification vendor.
 </ul>
 </li>
 <p>

 <li>
 <code>j3d.renderer</code>
 <ul>
 String that specifies the Java 3D rendering library.  This could
 be one of: "OpenGL" or "DirectX".
 </ul>
 </li>
