I'm looking for some visualisation software so I can do a 'walkthrough' of an unbuilt Victorian docks. It's just a hobby project, so ideally the software should be free though I'd be prepared to spend up to about £50 (I may go on to use it for other stuff) Basically, what I want to do is: Import a LIDAR surface (which I will have edited) as a basis for the project. Insert buildings and other structures such as dock gates and bridges. Also boats. Ideally allow animation (e.g. dock gates opening) Model water with boats floating on it. Ideally with rising/falling levels. Allow you to walk through and explore the area e.g. with WASD key control. VR support a big bonus. Any suggestions?
