◆ integrate()

int CurvedSpaceIntegrator::integrate	(	double	time,
		const pt &	O,
		const pt &	d,
		double	dist = `-1`,
		int	maxsteps = `5000`
	)

Call the integrate() function to compute line segments along a geodesic path.

Parameters

O	Ray origin
d	Ray direction
dist	Maximally allowed distance in coordinate space (not used currently)
maxsteps	The maximal number of step sizes, avoids infinite loops if finite.

virtual int CurvedSpaceIntegrator::segment_intersect	(	const pt &	where,
		const pt &	dir,
		double	segment_length
	)

pure virtual

Core function, which is called for each geodesic segment.

If it returns non-zero, integration is terminated and the return value is forward to the integrate() function.

void CurvedSpaceIntegrator::setCenter ( const pt & Center ) const

Set the coordinate location of the black hole's center.

virtual int CurvedSpaceIntegrator::straight_ray	(	const pt &	O,
		const pt &	d
	)

pure virtual

Virtual callback function if ray is straight, i.e.

in the flat space region far from the black hole and pointing to infinity.
