Method Summary

Modifier and Type	Method and Description
Vector3D[]	closestPointTo(Line line) Computes the points of the shape and the line realizing the shortest distance.
double	distanceTo(Line line) Computes the distance to a line.
Vector3D[]	getIntersectionPoints(Line line) Compute the intersection points with a line.
boolean	intersects(Line line) Tests the intersection with a line.

Method Detail

intersects

boolean intersects(Line line)

Tests the intersection with a line.

Parameters:

line - the line

Returns:

true if the line intersects the shape

getIntersectionPoints

Vector3D[] getIntersectionPoints(Line line)

Compute the intersection points with a line.

Parameters:

line - the line

Returns:

the intersection points if they exist. If no intersection is found, the dimension is zero

distanceTo

double distanceTo(Line line)

Computes the distance to a line.

Parameters:

line - the line

Returns:

the shortest distance between the the line and the shape

closestPointTo

Vector3D[] closestPointTo(Line line)

Computes the points of the shape and the line realizing the shortest distance. If the line intersects the shape, the returned points are identical : this point is the one with the lowest abscissa on the line.

Parameters:

line - the line

Returns:

the two points : first the one from the line, and the one from the shape.
