<h2>How to use JBullet</h2>
<p>To use Jbullet easily in the new processing 1.0, you can just follow these steps:</p>
<ol>
<li>install <a href="https://java3d.dev.java.net/">Java3D</a> to have access to some standard matrix operations in Processing &amp; Java. What you really need is only the vecmath class. If Processing (depending on the version &amp; settings) still does not see it, put the vecmath.jar inside processing&#8217;s libraries&#92;vecmath&#92;library.</li>
<li>download <a href="http://jbullet.advel.cz/" target="_blank">Jbullet</a> and be sure that you put jbullet.jar inside processing&#8217;s libraries&#92;jbullet&#92;library.</li>
<li>restart Processing if it was running.</li>
</ol>
<p>Download the <img src="/wp-giulio/wp-content/uploads/processing1.jpg" alt="Processing 1.0 pde file" title="Processing 1.0 pde file" width="16" height="16" class="alignnone size-full wp-image-820" /> <a href="/static/books.pde" target="_blank">books.pde</a> source code. And please, if you find this useful, post a link to your sketch or video that you did with this, I&#8217;m curious!</p>
<p>Addendum: if you want to use <a href="http://hipstersinc.com/p5sunflow/" title="P5Sunflow: Easy Ray Tracing from Processing.org">P5sunflow</a>, then use processing v135: the version 1.0 seems not to be working with it. The code of the sketch is compatible, but you have to install the libraries in the processing folder itself.</p>
