Version 3 of my city model is now available to download.
To create the model I used SketchUp, the 3D modelling software
used to model towns and cities for Google Earth. It's quite fun to
play around with and best of all it's completely free.
Download and install the most recent version of SketchUp for
Windows or Mac, depending on your system:
Download the 3D model of the city:
Then open the model up with SketchUp.
You can navigate around the city by selecting the white hand icon,
holding down the left mouse button and moving the mouse. Holding
down the middle mouse button lets you rotate. And the mouse wheel
lets you zoom in and out. Or if you don't have a mouse wheel, you
can use the blue arrow and the magnifying glass either side of the white
Also, the model was starting to cause some slow down issues, so I've
hidden several elements in layers. Click on 'window' on the top
menu, select 'layers', and then use the tick boxes to make these
elements visible or invisible. If your computer's struggling, try
unticking 'rest of the city.' If it's more powerful, tick them
Version 1 was rather abstract, with streets coloured by use (e.g.
yellow for houses) and no distinction between buildings.
Version 2 was constructed in much the same way, but the streets were
texture mapped so that they looked more like actual streets.
Version 3 is composed of around 50 individual
buildings, copied and pasted 1000s of times.
Every time I wanted to add more detail in the past, I would first
level the city, and then rebuild it after splitting the city into
smaller elements that repeated more often, to lessen the workload.
But now when I want to add more detail in the future, I only have to
work on 50 or so buildings.
So if anyone out there is crazy enough to try modelling their own
city design, I would strongly recommend ignoring the low polygon/texture
map advice for Google Earth modellers and going straight to the
individual building stage. Also, components and the default
(white) colour are your friends.
