curve2, curve3
Purpose
curve2, curve3
Constructor function for curve objects.
Syntax
Description
c3 = curve3(x,y,z)
c3 = curve3(x,y,z,w)
c3 = curve3(vtx,vtxpre,edg,edgpre,fac,mfdpre,mfd)
[c3,...] = curve3(g3,...)
c3 = curve3(g2)
c2 = curve2(x,y)
c2 = curve2(x,y,w)
c2 = curve2(vtx,edg,mfd)
[c2,...] = curve2(g2,...)
c3 = curve3(x,y,z) creates a 3D curve object. The degree is determined from
the number of control points given in the vectors, x, y and z. Length 2 generates a
straight line. Lengths 3 and 4 generates rational Bézier curves of degrees 2 and 3
respectively. Unit weights are used.
c3 = curve3(x,y,z,w) works similarly to the above, but also applies the positive
weights w to the control points of the curve.
c3 = curve3(vtx,vtxpre,edg,edgpre,fac,mfdpre,mfd) creates 3D curve
geometry object c3 from the arguments vtx, vtxpre, edg, edgpre, fac, mfdpre,
mfd. The arguments must define a valid 3D curve object. See geom3 for a
description of the arguments.
[c3,...] = curve3(g3,...) coerces the 3D geometry object g3 to a 3D curve
object c3.
c3 = curve3(g2) coerces the 2D geometry object g2 to a 3D curve object c3, by
embedding it in the plane z = 0.
c2 = curve2(x,y) creates a 2D curve object in the form of a Bézier curve, with
the control points given by the vectors x and y of the same lengths. Length 2
generates a straight line. Lengths 3 and 4 generates rational Bézier curves of degrees
2 and 3, respectively. Unit weights are used.
c2 = curve2(x,y,w) works similarly to the above, but also applies the positive
weights w to the control points of the curve.
c2 = curve2(vtx,edg,mfd) creates a 2D curve object from the properties vtx,
edg, and mfd. The arguments must define a valid 2D curve object. See geom2 for a
description of the arguments.
[c2,...] = curve2(g2,...) coerces the 2D geometry object g2 to a 2D curve
object.
