Detailed Description

Class representing a manifold with different coordinate systems and metrics.

This class represents a manifold with multiple coordinate systems, conversions between them and a metric, which can be expressed in either of the systems.

Member Function Documentation

Point Manifold::convertPointTo	(	Point	p,
		int	system
	)

Convert a point to another coordinate system.

Parameters

p	The point to be converted
system	The target coordinate system

Returns

Converted point

vector4 Manifold::convertVectorTo	(	vector4	v,
		Point	p,
		int	system
	)

Convert a vector to another coordinate system.

Parameters

v	The vector to be converted
p	The point at which the vector is defined
system	The target coordinate system

Returns

Converted vector

CoordinateConversion * Manifold::getConversion	(	int	i,
		int	j
	)

Get a coordinate conversion.

Parameters

i	Number of the source coordinate system
j	Number of the target coordinate system

Returns

Pointer to the conversion object

Metric * Manifold::getMetric

(

int

i

)

Get a metric.

Parameters

i	Number of the coordinate system

Returns

Pointer to the metric expressed in the chosen system

int Manifold::recommendCoordSystem ( Point  p )

virtual

Get the best coordinate system to use at a point.

Parameters

p

The point

Returns

The recommended coordinate system to be used

Reimplemented in KerrManifold, and SchwManifold.
