Creating arcs and NURBS curves

“

- [Instructor] In the last video, we used a set of points to construct straight curve types, more or less lines that connect points together. Now let's use those same points to create curves that will have some actual curviness to them. We'll start by drawing arks which have their own section of the geometry curves part of the node library. We see that there are lots of different methods to draw arks, each taking a different combination of inputs. We're going to try two of these methods out beginning with the ark by three points node. As its name suggests, this node takes three points for inputs. Let's feed it some of the points in the left side of our graph. Say the first, second and third points. You'll notice in our geometry preview that an ark is drawn through each of these three points. Maybe let's replace the third point input with a different point on our work space to see how the geometry updates. You can see it in our background preview, our ark is enlarged quite a bit to run…
