Future of 3D #3: Design, Print and Fly!

Co-founder and director of Intion Stuart Cupit, also keen photographer and kite-flyer, decided to set himself a challenge to build a rig capable of taking panoramic aeriel photos from his parafoil kite...

The Spec
The rig needed moving parts, had to be light-weight but strong enough to hold servos and a digital camera and withstand the odd crash landing. Stuart designed the rig using 3D Studio Max and included 5 independent moveable stages, a complete gear system, fittings for 4 servos, a microcontroller, batteries and, most importantly, a digital camera.

The 3D Print
The final design was printed out in one go (yes, no assembly!) using our Invision-XT 3D printer. The various joints and gears were designed in place with the 0.1mm clearance between any two parts required to  allow them to move independently. The VisiJet SR200 build material used is strong enough to be for functional finished products.

Servo Control and Support
The gears, axels and sleeves freely revolve and the fleixble nature of the material, when printed in thin sections, allowed the servos to be held in place by sprung hinged latches. The servos follow a pre-recorded set of moves using a Milinst Wizard board.

A Picavet suspension allowed the camera rig to self-level and prevents twisting. A geared mechanism reduced the speed of one of the servos by 20 to 1 to allow the rig to be rotated. The gears were printed in place and once support material is removed just work with no assembly!

The Flight
The whole rig was attached to a Sutton Flowform 16 kite using a pair wire hangups on 200m of cord. The kite needed a 25mph wind to get the 1kg rig into the air. Flown from Hamstead Heath, the rig took 50 blurry photos the first time! The second flight got some great shots looking south across London, and some bemused looks from on-lookers!

The kit we used: 3D Systems Invision XT (in-house), 3D Studio Max, Sony digital camera, Milinst Wizard Servo controller board, Sutton Flowform 16 kite

About our 'Future of 3D' series

The 'Future of 3D' series is about exploring the boundaries of future 3D technology through non-commercial creative projects. Supporting this type of work is core to Inition's core values of developing new uses of 3D technology, supporting creativity and nurturing the passion of it's staff and collaborators. If you have an idea for a 'Future of 3D' project, we'd love to hear from you.

Future of 3D: #2 - Sketch, Scult, Print

As part of Inition’s “Future of 3D” series, our 3D printing team worked with BA design student Kristin Katzer from the London College of Communication to realise a packaging design for fruits.

Concept
The concept for Kristin's organic design was based on structures of nature, in particular her research into “tafoni structures” produced during the calcification of porous sandstone.

Freeform Design
Designing these organic structures using a typical 3D CAD package would have proved very difficult, however with Inition's guidance Kristin realised the design through the intuitive interface of the Sensable Phantom Omni in conjunction with the Claytools software. Claytools is a design package specially tailored towards haptic modelling, allowing the user to directly sculpt, manipulate and feel the surface of a model through a pen-line interface attached to a motorised force-feedback arm.

3D Print
After adding colour to the CAD model, the complex design was prepared for print Paul Armand, one of Inition's 3D printing specialists. Our full colour 3D ZPrinter 450 printed out the model over-night including two end caps with extruded lettering. The final design forms part of Kristin’s degree and was shown at the BA Design Show at the London College of Communication in June 2011.

Future of 3D
Inition’s “Future of 3D” series encourages work on non-commercial projects which help to push the boundaries of current 3D creative and technology. This was the first time we had seen a project go from sketched concept, through haptic modelling to a physical 3D printed model. Organic designs are not usually immediately associated with computers but with Claytools strength in creating organic shapes and our 3D printer's ability to print them, we see a great future for this combination of technologies in product design.

The kit we used:  ZPrinter 450, Phantom Omni with Claytools software

Thanks to Kristin for creating a great piece; the first thing we've 3D printed that has been created on a haptic device. Check out our Future of 3D blog at fo3d.posterous.com for our latest experiments.

After collaborating with Inition on several test shoots, world famous fashion photographer Rankin chose Inition to supply the stereoscopic crew, expertise and equipment for a new pop music promo from Kelis called ‘Scream’. 

3D on a 2D Schedule

It was essential that the 3D aspect did not add time to the one day/2D schedule. Inition used an Element Technica Quasar rig and SI-2K 3D camera system. Element Technica's motorised alignment, excellent rigidity and precise alignment, meant less correction was required on set and in post production, ideal when time was of the essence as it was with the Kelis 'Scream' production schedule.

Brett Turnbull, DP on the shoot said: "We shot 'Scream' in 2D and 3D simultaneously using the same camera system. The whole set-up was very flexible and mobile, allowing us to experiment and see instant 3D playback on set. With an ambitious storyboard and limited shooting time, it was a real bonus that shooting in 3D actually had very little impact on the day's schedule.” 

On the day of shooting, Inition supplemented the regular crew with a stereographer, rig technician and camera assistant, and supervised the post production which was completed at OnSight, ensuring that Rankin’s trademark photographic style was not comprised and actually enhanced by the stereography.

YouTube Hit

‘Scream’ 3D by Kelis was launched as an anaglyph 3D video exclusively on video sharing website YouTube, generating over half a million hits and counting. It features an exciting combination of negative and postive parallax shots, perfectly suited for the genre of a music video.

Inition's crew and equipment ensured the production schedule was adhered too and the director was able to fully concentrate on the creative process.

Six Nations Live to 40 Cinemas

40 cinemas across the country screened England’s home RBS Six Nations games live in 3-D. Archibald Ingall Stretton commissioned 3D specialists Inition to produce the matches which became the largest ever UK sports event to be broadcast live in 3D. Forty Odeon and Cineworld cinemas screened the matches, beginning with England’s official centenary game, against Wales on February 6, as part of a deal with O2, the England sponsor. The match against Ireland on February 27 was also screened live in 3-D.

3D Technology

Using the latest 3D camera technology, the matches were captured from seven camera positions providing a comprehensive view of the game which included replays, match statistics and on-screen graphics. Inition worked with outside broadcast experts SIS Live and used 3D 'Quasar' rigs from Element Technica for the shoot. Broadcast graphics specialists Wurmsers creating bespoke stereoscopic graphics for the game.

Production Team

The BBC is the UK TV rights holder for the 6 Nations – played between England, Scotland, Wales, Ireland, France and Italy – and assisted Inition in the broadcast. Inition has worked on a number of 3D productions from football and ice hockey to track and music events. Inition were also the 3D experts behind the 3D transmissions of England’s clash with Scotland at Murrayfield, in 2008, as part of a 3D test for the BBC.
