I can’t believe I just typed that sentence. The video is up, and here it is:
Musk showed a wireframe of the rocket part, and he was able to rotate the 3D object on a screen with one hand, and with a second hand, he zoomed in and out, moved it around the screen, and spun the object around and “caught it”--all in the air.
He moved on to manipulating an actual 3D CAD model and interacting with the software; you can see that he used a Leap Motion controller. He performed pretty much all the same motions as above, but it appears as though he was able to “click” certain areas, too.
Next, he shows off a 3D projection, a freestanding glass projection (Ironman style), and interacts with the model using the Oculus Rift. Finally, he prints the part in titanium with a 3D metal printer.
The input methods he demos are powerful, although he’s just using existing technology to do it. This isn’t really a future-leaning endeavor per se. Finally, note that we don’t actually see him design anything; the models he works with are already made. Still, it’s exciting to see new ways of doing things come to life on screen.
