3D Cuneiform Interactive Viewer v3.0

This latest version 3.0 of our joining interaction interface includes a new control button for lighting direction and a new option button to switch collision detection on and off (the default is off).

About this interaction: This interaction builds on an original version presented at the interactions gallery at the 2017 BCS HCI conference. The interactive 3D model viewer is implemented using WebGL with the THREE.js JavaScript library. The 3D models were created using structure-from-motion photogrammetric reconstruction. Sets of 36 photographs taken using a synchronised turntable were combined with virtual calibration photographs using VisualSFM to estimate the camera parameters. A customised bundle adjustment algorithm refined the estimates using a-priori knowledge about the exact known properties of the virtual photographs. Finally, MVE was used to generate dense point clouds which were aligned and merged before the mesh was formed using MeshLab and photographic texturing added.
