Method Summary

double	distance(Vertex2D start, Vertex2D end) Returns the distance between two points.
double	distance2(Vertex2D start, Vertex2D end, Metric2D m2) Returns square distance between two points.
double[]	getBounds2D(Vertex2D vm) Returns bounds of unit ellipse centered at a point.
double	length(VirtualHalfEdge2D ot) Returns the length of an edge.

Method Detail

length

double length(VirtualHalfEdge2D ot)

Returns the length of an edge.

Parameters:

ot - edge being measured

distance

double distance(Vertex2D start,
                Vertex2D end)

Returns the distance between two points. Metrics on both points is used to interpolate this length.

Parameters:

start - the start node

end - the end node

Returns:

the distance between these two points.

distance2

double distance2(Vertex2D start,
                 Vertex2D end,
                 Metric2D m2)

Returns square distance between two points. This distance is evaluated by using metrics at a given point.

Parameters:

start - start node

end - end node

m2 - Riemannian metrics

Returns:

square distance between these two points.

getBounds2D

double[] getBounds2D(Vertex2D vm)

Returns bounds of unit ellipse centered at a point. This routine returns a double array which represents enclosing bounding box of unit ellipse. This method is used by KdTree.getNearestVertex(org.jcae.mesh.amibe.ds.Mesh, org.jcae.mesh.amibe.ds.Vertex); if an octant does not intersect this bounding box, it does also not intersect unit ellipse.

Parameters:

vm - the vertex on which metrics is evaluated

Returns:

bounding box of unit ellipse
