Detailed Description

Bounds for a conical surface, the opening angle is stored in $\tan(\alpha)$ and always positively defined. The cone can open to both sides, steered by $ z_min $ and $ z_max $ .

Acts::ConeBounds::ConeBounds ( )

delete

Acts::ConeBounds::ConeBounds	(	double	alpha,
		bool	symm,
		double	halfphi = `M_PI`,
		double	avphi = `0.`
	)

noexcept

Constructor - open cone with alpha, by default a full cone but optionally can make a conical section

Parameters

alpha	is the opening angle of the cone
symm	is the boolean indicating if the cone is symmetric in +/- z
halfphi	is the half opening angle (default is pi)
avphi	is the phi value around which the bounds are opened (default=0)
