About 3D Modelling
Today I have been learning about design roller coasters on the computer using 3D modelling. We use 3D modelling for roller coasters so we know how high and low we need to make the loops. If there is to much force then the person could become sick or even pass out, by using computers we can tell when this happens. If something is wrong with the roller coaster we can change it quickly and efficiently on the computer rather than having to take it completely apart and build it again which wastes a lot of time and money. 3D modelling is not only used for roller coasters it can be used for kitchen designing making sure everything fits, designing a car to see if it works or not and designing animated characters for films and TV programmes.
