Tools and Materials
To make your terrain three-dimensional modeling capability does not require any special or materials and tools that are particularly expensive, but needed materials and specific tools without which good results will be much more difficult.Colla First you have to procure a few brushes, glue and possibly food. not brushes are needed particularly special quality or vinyl glues, I'll you can get in any shop or store items at low cost. There will also be very useful a small ruler and a soft pencil.
If you have a chance try to collect various types of very fine dust and sand that can be very useful during the construction. A necessity is a very specific and also saw hot for polystyrene. The hot saw only costs a few dollars but it is only available in hobby shops or on the Internet. Do not think you can get the same results with a sharp cutter or a knife heated over a fire, the results are not even comparable. In hobby shops you can also buy artificial grass, but not the filament, but the one on the grains, if not already I suggest you buy assorted shades of two different and mix. In the end you have to buy the particular synthetic grass called Flock, Flock is the erbino of a spongy texture that will be used to simulate the largest vegetation.
A very useful material that you will always find in hobby shops is Plasticard. The Plasticard is sold in sheets of A4 paper of various thickness and is basically a sheet of plastic that can be engraved, cut and pasted very easily. The advantage of plasticard is that unlike the cardboard will not bend because of the humidity and will remain rigid and perfectly flat.
And we finally reached the main material for our achievements, Polystyrene, be careful I did not say Polystyrene. Polystyrene is a particular type of foam and refined much more compact and resistant, in contrast to the polystyrene breaks with difficulty and does not crumble into small balls. You can buy it from retailers of building materials and is sold in approximately 120 X 60 panels to be used as thermal insulation, then a panel will have enough to build all the infrastructure you want. The panels are available in various thicknesses, typically green or pink, you will need the thinner, often 2 cm. The saw to the foam with a battery powered from 4.5 volts should develop enough heat to cut even the polystyrene, although a little 'more slowly. If you have an old power for small appliances that develops a voltage between 6 and 9 volts would be a good idea to use it to feed your hacksaw, the tension is not likely to damage the filament of the jigsaw and will allow you to develop that little extra heat also easy to cut polystyrene. I think it's all in the various articles dedicated to the achievements from time to time you will find the directions of how to use the materials or where to find specific ones addressed to the realization.
