<h2>1.2 Features</h2>
<p>This section covers version 3.7 changes and new features that apply to POV-Ray for Unix. See the section <a href="t2_1.html#t2_1_4_1">Changes and New Features Summary</a> for information about <em>non-platform</em> specific changes.</p>
</div>
<a name="u1_2_1"></a>
<div class="content-level-h3" contains="New Features" id="u1_2_1">
<h3>1.2.1 New Features</h3>
<ol>
<li>Reworked the built-in <code>--benchmark</code></li>
<ul>
<li>The built-in benchmark now accepts the <code>+L<path></code> command-line option</li>
<li>and now <em>ONLY</em> reads the built-in INI file.</li>
<li>It also accepts <code>+wt</code> to set the number of work threads</li>
<li>and now also accepts the <code>--version</code> parameter</li>
</ul>
<li> Added preliminary Linux support for these two features:
<ul>
<li> CPU timer; might return incorrect results depending on the platform.</li>
<li> signal catching when aborting a render by hitting Ctrl+C</li>
</ul>
<li> Added support for the <code>+P</code> option to allow <em>pause when done</em>.</li>
<li> Unix default file gamma changed from from 1.0 to 2.2.</li>
</ol>
</div>
<a name="u1_2_2"></a>
<div class="content-level-h3" contains="Display Options" id="u1_2_2">
<h3>1.2.2 Display Options</h3>
<p>The Unix version now has a single binary which supports display using the X Window System, or using the SVGA library with the console on <em>GNU/Linux systems only</em>, or via text graphics otherwise. If the command-line options or INI files turn on display, the following heuristic is used to determine what kind of display should be used. If the DISPLAY environment variable is set, the X Window display is used. Otherwise, if the user is on the console, and has permission to do so, SVGAlib is used. Otherwise, text graphics are used.</p>
<p>Text graphics display a crude 75x24 ASCII version of the image which can be useful none the less to monitor the render progress on a text terminal. Using text graphics and the Verbose <code>+v</code> option simultaneously will not work very well.</p>
<p class="Note"><strong>Note:</strong> See the section <a href="u1_7.html#u1_7_1">Known Bugs</a> for more information about a problem with the X11 windows system.</p>
</div>
<a name="u1_2_3"></a>
<div class="content-level-h3" contains="Benchmark Mode" id="u1_2_3">
<h3>1.2.3 Benchmark Mode</h3>
<p>POV-Ray 3.7 for Unix provides a new mode to render a built-in version of the standard POV-Ray benchmark scene. See the <a href="u1_6.html#u1_6_2">Benchmark Rendering Mode documentation</a> for details.</p>
</div>
<a name="u1_2_4"></a>
<div class="content-level-h3" contains="Sample scene render scripts" id="u1_2_4">
<h3>1.2.4 Sample scene render scripts</h3>
<p>POV-Ray 3.7 includes a set of shell scripts to automatically render all the samples coming with POV-Ray and that generate HTML files to easily browse the sample scenes. See <a href="u1_3.html#u1_3_6">Rendering the Sample Scenes</a> for more information.</p>
</div>
<a name="u1_2_5"></a>
<div class="content-level-h3" contains="KDE Integration" id="u1_2_5">
<h3>1.2.5 KDE Integration</h3>
<p>The binary package for x86-Linux (<code>povlinux.tgz</code>) comes with an install script that generates some useful entries in the <a href="http://www.kde.org/">KDE</a> panel for convenient access to the POV-Ray documentation and configuration files.</p>
<p>The generic Unix source distribution also comes with the <code>kde_install.sh</code> script to perform the same task.</p>
