You don&amp;#x27;t get a physical object at the end but you do have a lot more flexibility in the structure and appearance, and, of course, the magical power of the undo button. And maybe you &lt;i&gt;could&lt;/i&gt; get a physical object out with the help of a 3D printer...&lt;p&gt;&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;tiltbrush.com&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;tiltbrush.com&lt;/a&gt;&lt;p&gt;I believe 3D sketching and CAD will be the first popular non-game application of virtual reality. 3D CAD with 2D I&amp;#x2F;O (mouse and flat monitor) has always been a little too difficult for the masses. Virtual reality with natively 3D input and output makes 3D CAD an order of magnitude easier and more fun. It could give a real boost to the 3D printing market too, as once the masses start doing CAD they&amp;#x27;re definitely going to want to print their creations.</text><parent_chain></parent_chain></comment><story><title>Protopiper: Physically Sketching Room-Sized Objects at Actual Scale</title><url>http://hpi.de/baudisch/projects/protopiper.html</url></story>
