With the advent and proliferation of tablets, using a pen to annotate or even sketch is becoming more and more useful, if not necessary. Enter the Space Pen. Now, you can sketch or annotate 3D models on the web. Developed at the University of Washington’s Design Machine Group, this tool provides an ideal interface with another of the group’s projects, Spot, the daylight measuring tool for architects.
Is Space Pen really as simple as it sounds? Can you really just draw and edit any 3D model? Yes. But it is not just that you can draw on any surface, it also recognizes certain basic shapes to aid in the drawing process. It also automatically renders a 3D floor plan from one’s model in real time. Another boon is the addition of a “light pen” allows users to add directional light to the drawing. It’s also free.
