Function Documentation

frame_table()

frame_table	(	Basecurve	curve,
			t = None )

Arrays r, T, n, b (m,3) and tau, kappa_g, kappa_n (m,) at the parameters t.

tape_corners()

tape_corners	(	Basecurve	curve,
		float	width,
		float	thickness,
			t = None,
			theta_T = 0.0 )

Corner points (m, 4, 3) of the tape cross section along the curve.

Local cross-section coordinates: x0 along b (width), y0 along -n (thickness),
consistent with `Basecurve.transform`.  Corner order: (-w/2,-d/2), (w/2,-d/2),
(w/2, d/2), (-w/2, d/2).

write_stl_tape()

write_stl_tape	(	Basecurve	curve,
		float	width,
		float	thickness,
		str	path,
			t = None,
			theta_T = 0.0 )

Binary STL of the tape as a swept box (four side faces plus two end caps).

write_vtk_polyline()

write_vtk_polyline	(	Basecurve	curve,
		str	path,
			t = None )

Legacy ASCII VTK polydata: the curve as a polyline with T, n, b and curvatures as point data.
