For each line of the geodataframe, a loop returns the coordinates of the gallery points. A spline is created for each group of points. This spline is then transformed into a tube.

galeries = []

for idx, row in gdg.iterrows():
    vertices = np.array(row['geometry'].coords)
    line = pv.Spline(vertices)
    galeries.append(line.tube(radius = row['radius']))

b = pv.MultiBlock(galeries)

b.plot()
#b.save('./tmp_files/galeries.vtm',binary=False)
