D3tube::D3tube	(	double	r_,
		double	r2_,
		double	l_,
		double	x,
		double	y,
		double	z,
		double	phi_,
		double	theta_,
		double	psi_,

		PD3element	parent = NULL
	)		[inline]

Creates a tube with outer radius r_, inner radius r2_ and length l_.

r2_ should be smaller than r_ for the correct norm.

The bottom of the tube is centered at (x,y,z).

The angles phi_, theta_ and psi_ can be declared in degrees and represent Euler-angles.

The Center (x,y,z) specifies the center of the Euler-rotations

The Euler-rotations occur in the following order:

phi_:..........Rotation around z-axis...................................x -> x'......y -> y'.......z -> z
theta_:......Rotation around the rotated x-axis (x'):.........x'-> x'......y' -> y''......z -> z'
psi_:..........Rotation around z'-axis:.................................x'-> x''......y''-> y'''.....z'-> z'

For phi_ = theta_ = psi_ = 0, the bottom of the tube lies in the x,y-plane and the z-extension correspond to the length l_.

The parameter sectors_ provides an option for refinement. It is set to 12 by initialization but can also be set manually.
A value of sectors_ = 8 creates a cylinder with 8 edges on the bottom for example. sectors_ is not limited to powers of two or even numbers!! 5 or 11 works as well.
