Rollercoasters and 3D effects

Why 3D programming is important

3D Design

3D design is important for many things, like making cars or kitchens , or even roller coasters. They use it fr roller coasters to make sure the weight wont make the ride brake, or with a simulator use it for knowing if it is physically stable. Without it it would cost thousands more to build and if its wrong then you would have to take it down to rebuild.
