It is important to note here that NURBS can be easily converted to Meshes at any time, in the same way that you can easily take a digital image of a person’s face with a camera. Thus they behave more like a real person’s face rather than a pixelized image of that same face. There is no pixelization or granularity as with a mesh. They are capable of representing complex free form surfaces that are inherently smooth, and they keep their smooth shape when editing. NURBS surfaces are mathematical representations of curves and surfaces. Yet, if we zoom in enough, we can still see the “pixelization” or granularity and that the object is not locally smooth and continuous.
If the facets or pixels are small enough, the image appears “smooth”.
Although both can represent a 3D object as a computer model, they do it in completely different ways.Ī mesh represents 3D surfaces as a series of discreet facets, much as pixels represent an image with a series of colored points. To understand what MeshToNurb does, one must also understand the fundamental differences between a Mesh model and a NURBS surface model.
