public interface Interpolation

Represents an arbitrary function in ℝ → ℝ³

Method Summary

Modifier and Type	Method and Description
double	arcLength(double positionA, double positionB) Gets the result of ∫ab|f'(t)| dt. That means it calculates the arc length (in meters) between positionA and positionB.
Vector	get1stDerivative(double position) Gets the result of f'(position).
Vector	getPosition(double position) Gets the result of f(position)
int	getSegment(double position) Get the segment position.
void	setNodes(List<Node> nodes) Sets nodes to be used by subsequent calls to getPosition(double) and the other methods.

Method Detail

setNodes

void setNodes(List<Node> nodes)

Sets nodes to be used by subsequent calls to getPosition(double) and the other methods.

Parameters:

nodes - the nodes

getPosition

Vector getPosition(double position)

Gets the result of f(position)

Parameters:

position - the position to interpolate

Returns:

the result

get1stDerivative

Vector get1stDerivative(double position)

Gets the result of f'(position).

Parameters:

position - the position to interpolate

the result

arcLength

double arcLength(double positionA,
                 double positionB)

Gets the result of ∫_a^b|f'(t)| dt.
