Comparing NURBS surfaces and mesh surfaces

“

This this video, we'll define and review the visual terminology relating to NURB surfaces. Which includes the confusing term Mesh. Which can then be used to describe two totally different, but related things. We'll also define an isocurve and what it is trying to communicate to us. So I've used the NURB surface from earlier and built this lovely boat. The two lines on the surface are called isocurves, and are intended to give you a visual feedback of the surface smoothness and complexity. Remember, a NURB surface is always infinitely smooth, and it's based upon the math that was used to create it. You also have an opportunity to change the density of these isocurves if it's just your personal preference. Let's show where that is adjusted here under Properties tab. And I'm going to crank this up to about 30. So these are just feedback display curves, they do not change the complexity of the surface at all. If I put it back to the original one, and then I'm going to turn on the control…
