loft

FV = loft(C1, C2; n_steps::Int=0, closed=true, type=:quad)::GMTfv

Loft (linearly) a surface mesh between two input 3D curves.

Args

• C1, C2: Two Mx3 matrices of points defining the 3D curves to loft. Each row is a point in 3D space.

Kwargs

• n_steps: The number of steps used to build the lofted surface. If 0 (the default) the number of steps is computed from the curve point spacing.

• closed: If true (the default), close the lofted surface at the top and bottom with planes created with C1 and C2.

• type: The type of faces used to build the lofted surface (:quad (default), :tri).

Returns

A GMTfv FacesVertices object.

Example

using GMT
	
ns=75; t=linspace(0,2*pi,ns); r=5; x=r*cos.(t); y=r*sin.(t); z=zeros(size(x));
C1=[x[:] y[:] z[:]];

f(t) = r + 2.0.* sin(6.0*t)
C2 = [(f(t)*cos(t),f(t)*sin(t),3) for t in range(0, 2pi, ns)];
C2 = stack(C2)'

FV = loft(C1, C2);
viz(FV, pen=0)
