Constructor Detail

Triangulation

Triangulation(int numPoints)

WRITEME: Document this constructor brpocock@star-hope.org

Parameters:

Method Detail

addEdge

public int addEdge(int s,
                   int t)

WRITEME: Document this method brpocock@star-hope.org

Parameters:

s - WRITEME

t - WRITEME

Returns:

WRITEME

addEdge

public int addEdge(int s,

t - WRITEME

l - WRITEME

r - WRITEME

Returns:

WRITEME

addTriangle

WRITEME: Document this method brpocock@star-hope.org

Parameters:

s - WRITEME

t - WRITEME

u - WRITEME

copyPoints

public void copyPoints(Triangulation t)

Copies a set of points.

Parameters:

t - WRITEME

findEdge

                    int t)

WRITEME: Document this method brpocock@star-hope.org

Parameters:

s - WRITEME

t - WRITEME

Returns:

WRITEME

print

public void print(PrintStream p)

WRITEME: Document this method brpocock@star-hope.org

Parameters:

p - WRITEME
