When an engineer is trying to work out the aerodynamics of a plane or car, and they want to run tests in a digital wind tunnel. This means that it is far better suited for models where a high degree of accuracy is needed.Ī good example where this is important is in engineering. NURBS (which is shorthand for Non-Uniform Rational B-splines) uses complex mathematics to calculate the surface of a model. NURBS calculates the mesh as splines between points, which can make curves out of a single section of geometry. The main difference between polygonal and NURBS modeling is the way the mesh is calculated by the computer.įor polygon modeling it calculates polygons, which are flat planes that comprise a 3D shape (the way that a cube is made out of 6 squares for example).
