“…Use of gestures for 3D modelling is shown in Figure 5, using boxes numbered 1-5. 3D modelling includes: 3D architectural urban planning (Buchmann et al, 2004, Yuan, 2005, Cable harness design (Robinson et al, 2007), CAD Design (Dani and Gadh, 1997, Kim et al, 2005, Qin et al, 2006, Holz and Wilson, 2011, Kang et al, 2013, Vinayak et al, 2013, Arroyave-Tobón et al, 2015(Huang et al, 2018), CAD Manipulation (Chu et al, 1997, Kela et al, 2006, Qin et al, 2006, Bourdot et al, 2010, Kang et al, 2013, Vinayak et al, 2013, Song et al, 2014, Beattie et al, 2015, Noor and Aras, 2015(Xiao and Peng, 2017), and Virtual Pottery (Dave et al, 2013, Han and Han, 2014, Vinayak and Ramani, 2015. All of these applications were used to create, modify and manipulate 3D models, and were characterised by the dependence on 3D visualisation and the perception of 3D space.…”
