extrude

FV = extrude(shape::Matrix{<:AbstractFloat}, h; base=0.0, closed=true)::GMTfv

Create an extruded 2D/3D shape.

Args

• shape: The shape to extrude. It can be a 2D polygon or a 3D polygon defined by a Mx2 or Mx3 matrix or a GMTdataset

• h: The height of the extrusion. Same units as in shape.

Kwargs

• base: The base height of the 2D shape to extrude. Default is 0. Ignored if the shape is a 3D polygon.

• closed: If true (the default), close the shape at top and bottom.

Returns

A GMTfv FacesVertices object.

Example

Extrude the Swisserland.

using GMT

Dsw = coast(dump=true, DCW=(country=:CH, file=:ODS));	# Get the Swiss border
FV = extrude(Dsw, 0.2)
viz(FV, zsize=1)

And a much nicer example combining extrusion and painting top surface with flatfv.

using GMT

# Low resolution country polygons
Dit = coast(M=true, DCW=(country=:IT, file=:ODS));

# Extrude and paint the quadrangulated mesh
FV = flatfv("@earth_day_01m", shape=Dit, thickness=0.5);

viz(FV, zsize=0.5, frame=:none, view=(200, 45))
