LONDON.- The Science Museum Group
has today published a high-resolution 3D model of Stephensons Rocket, enabling audiences across the globe to examine this iconic locomotive in unprecedented detail for the very first time. Rocket measures over four meters in length and weighs three tonnes, making it the most complex and largest item from the Science Museum Group Collection ever to be 3D scanned.
The intricate model was published as Rocket went on public display at the Science and Industry Museum in Manchester, returning to the Liverpool Road station it served almost two centuries ago.
Rocket secured its place in history after winning the 1829 Rainhill trials, reaching a top speed of 30mph. Manufactured earlier that year by Robert Stephenson and Company in Newcastle, Rocket brought together several efficiency and performance innovations highlighted on the 3D model and its ground-breaking design became the basis for subsequent steam locomotives.
Thanks to the 3D model, Rocket can now be studied in detail from anywhere in the world. Audiences can move this three-tonne locomotive around with ease on screen, peer underneath and explore the innovations which made Rocket the fastest locomotive of its time. Created using 22 high resolution LIDAR scans and over 2,500 detailed photographs, the 3D model has been published on the Science Museum Group Collection website and on Sketchfab, the worlds largest 3D content platform.
Working with Science Museum Group colleagues, a team from ScanLAB spent 11 hours recording every angle of Rocket to create the 3D model using over 200kg of camera, lighting and scanning equipment. Scanning and photography was particularly challenging due to Rockets colour, glossy texture and complex shape.
After six weeks of processing the LIDAR data and 220 gigabytes of photography, a highly detailed point cloud was produced, containing spatial coordinates, colour and intensity values for a staggering 750 million points. A further two weeks of processing was needed to produce several 3D models of Rocket, one of which featuring 84,000 vertices has been published today. Work is ongoing to explore additional uses for the point cloud data and 3D scans, including through augmented reality.
The 3D model of Rocket was created by the Science Museum Group Digital Lab supported by founding sponsor Samsung.
