Mostreremo un possibile codice per disegnare e ruotare un Prisma triangolare intorno al suo asse Y in una ''DrawingArea''.&lt;br /&gt;
&lt;br /&gt;
Nell'esempio che segue sarà possibile aumentare o diminuire la dimensione del disegno del Prisma, cliccando rispettivamente sui tasti &amp;quot;+&amp;quot; e &amp;quot;-&amp;quot; della tastiera.&lt;br /&gt;
