3D Scanning Wallace And Gromit maquette
The task for the Europac3D team was to produce an extremely high-resolution 3D scan of the model, in order that all the original thumb prints and handmade artist impressions could be translated into the larger than life bronze statue. The Artec Space Spider was chosen for the job because of its high data collection rate of 1,000,000 points per second. This incredible resolution means that even the smallest of details can be captured by the 3D scanner and translated into the final sculpture.
The whole 3d scanning process took about 45 minutes to capture and then the huge data point cloud was converted into a triangulated CAD surface model or STL file using Artec Studio software. In addition, our in-house artists were tasked to add details such as the text on the newspaper which was prepared By Aardman animations.
The candidate model was then rendered using Keyshot software to help visualise how the statue might look when manufactured in bronze. This enabled, all parties such as Preston Town Council, Aardman animations and even Nick Park himself to inspect the digital model before actual production had begun. In addition to these rendered still images, the digital model was uploaded to Sketchfab, a 3d model visualisation platform, and given to Ian Banks of Atoll UK. Ian had been commissioned as the Public Art Consultant for the project by Preston Town Council and he was able to use the digital model for augmented reality visualisation in the proposed site for the installation. Using the camera of a smartphone or tablet the digital model of Wallace and Gromit could be placed virtually in position and walked around from all angles. This is a great tool to get a real sense of how the final sculpture might look like long before manufacturing begins.
