Drawing in 3D will soon be as
"intuitive as sketching with paper"

Dezeen and MINI Frontiers: architects will soon be able to walk around inside 3D sketches of their projects and edit their designs as they go, according to the team behind the revolutionary Gravity Sketch 3D drawing pad.

"You've done the CAD drawing and you want to make some amendments in the virtual reality that you've just created," said Oluwaseyi Sosanya, one of a team of four Royal College of Art and Imperial College London students who developed the device.

"You can you can just plug in with [virtual reality headset] Oculus Rift and walk around this environment and make amendments."

Sosanya demonstrated Gravity Sketch to Dezeen in Milan earlier this month, explaining that it made drawing in 3D as "intuitive as sketching with paper".

"Gravity Sketch is a tool for creatives to quickly sketch out ideas in 3D space," he said. "It's a bridge between paper and computer. We wanted to make it just as natural and intuitive as sketching with paper."

The device consists of a clear acrylic tablet with a joystick and a sliding control on one side. The user sketches on the tablet – called a "landing pad" – in 2D with a stylus held in one hand while manipulating the controls with the other, to create the third dimension of the drawing.

"You sketch in this 2D plane," says Sosanya, while demonstrating the device by drawing the outline of a car on the pad. "With the controls on the pad you can adjust the Z [axis] and move the plane in which you're sketching."

Sosanya then adjusts the Z axis using the controls and draws a second car outline, parallel to the first. He then completes the 3D sketch by rotating the two outlines and drawing perpendicular lines to join them together, creating a 3D sketch of a car. "It's kind of like drawing construction lines of what your volume or your 3d object is going to be in the end," he says.

The drawing is displayed via a virtual reality headset like Oculus Rift or an augmented reality device like Google Glass.

Drawings can be rotated and approached from any angle and other people can view and edit them via their own headset.

Devices like Gravity Sketch also mean that architects will one day be able to walk through 3D models to make changes as they go, says Sosanya. "I think this is good for an architect or interior designer," he says. "You can make adjustments to the elements you want to change in the model." The technology could be also applied to fields such as animation or medical science, he adds.

Despite predictions about computer-based drawing replacing hand drawing, Sosanya believes sketching has a long future, helped by new technologies like augmented and virtual reality. "I don't think we'll ever lose the ability to sketch with a pen," he says. "We are still quite attached to the physicality and the tactility [of hand drawing]."

The Gravity Sketch team are currently in their final year of the joint Innovation Design Engineering MA at the Royal College of Art and Imperial College London. Sosanya's colleagues are Guillaume Couche, Daniela Paredes Fuentes and Pierre Paslier. The team are currently in talks with a number of investors from the augmented reality community and hope to launch a series of developer kits by the end of summer 2014.

    I’m all for finding easier ways for architects to transition from paper to digital, but I honestly could never imagine designing with this thing.

    How is it easier to sketch something in 3D when you have to manually switch planes with your other non-drawing hand? When I draw in 3D on paper all you have to do is actually draw the next 3D plane, which is one less step. Seems like this is trying to replace the thought process in drawing, which doesn’t appear to need innovation.

  • Spagett

    That looks extremely natural.

    • hauntore

      Because they use a pen? It doesn’t.

  • Brandon

    This has to be worked a lot. First off, most architects are accustomed with spectacles. So that might be needed to be taken into consideration. And secondly, I am still not sure how convenient would it be for designers or architects to draw with such a big headset in the name of technological advancement. That would be highly exhausting and therefore contribute to more lesser productivity. Thirdly, I have a feeling of how accurate it can get. I mean sketching is never accurate. It might look spectacular but at the end, CAD drawings are what we really need in reality. With all the different commands embedded in different software packages, it might be just hard for people to engage the commands at the same time trying to draw at ease. As far as this idea goes, this is very sketchy and would recommend for nominal idea sketch works.

    This will be terribly inaccurate and limited, no way you could use this in real architecture or design. It could at most make easy annotations in pre-made drawings (which could be useful) but please don’t try to fool inexperienced minds with fancy drawings.

    They used rhinoceros?
