Hi,
We are a small, UK based team of Visualisation Dudes and we have just completed our first Unity project.
We have used Unity to illustrate the visual changes to the Pedestrian and Cyclist Tunnels, under the River Tyne, North East England.
We also converted our existing VR model of the new Vehicular Tyne Tunnel, and integrated it within the visualisation. Although this is lacking in polish somewhat!
We come from design based backgrounds so the programming was a serious learning curve for us (the hud implementation is still far from perfect), so many thanks to everyone on the forum who relpied to my queries!
Any feedback would be much appreciated but as its our first attempt try and go easy on us
