This example shows how to use the spmak, spcrv, cscvn and rscvn Using fnplt directly with this particular spline curve gives the red curve in the figure below. Therefore, all the B-splines of order 4 for this knot sequence are 0 at the hold on t = 3:.4:6.2; cv = fnval(curve, t); cdv = fnval(fnder(curve), t); quiver(cv(1,:),cv(2,:),
Find SPLINE creates curves called nonuniform rational B-splines (NURBS), referred to as By default, fit points coincide with the spline, while control vertices define a control frame. The prompts differ, depending on whether you choose Fit or CV (control vertices) as the An example is the green curve in the illustration.
The curve is an open B-spline curve. In this case, we should be careful about one additional restriction. On a previous page we showed an example of basis
curves is geometrical in nature, but in Section 1.6 we show that spline curves .. Some examples of cubic interpolants are shown in Figure 1.6, and the same
This tutorial covers the basic issues of dealing with the RenderMan's curve primitive. In particular, notice the green bezier curve is the only one to begin and end at the first and last cv. The RIB statements used to render the bezier curve are,

B-spline function is a combination of flexible bands that passes through the number of points that are called control points and creates
