Constructor Detail

Wall

public Wall(Point3d v1,
            Point3d v2,
            Point3d v3)

Constructs a new Wall. The vertices cannot be altered after construction

Parameters:

v1 - The first vertex

v2 - The second vertex

v3 - The third vertex

Wall

public Wall(java.io.DataInputStream dis)
     throws java.io.IOException

Constructs a new wall from the stream

Parameters:

dis - The stream to read from

Throws:

java.io.IOException

Method Detail

encode

public void encode(java.io.DataOutputStream dos)
            throws java.io.IOException

Encodes the vertices to the stream

Parameters:

dos - The stream to write to

Throws:

java.io.IOException

blocksTransmission

public boolean blocksTransmission(Point3d p1,
                                  Point3d p2,
                                  MessageShell shell)

Determines if this wall blocks a transmission

Parameters:

p1 - The origin of the transmission

p2 - The target of the transmission

shell - The shell used in this transmission

Returns:

true if the wall blocks the transmission, false otherwise

getBoundingBox

public Point3d[] getBoundingBox()

Gets an axis aligned bounding box for this wall

Returns:

A two-element Point3d array. The first element is the vertex of the bounding box closest to (-∞, -∞, -∞ ), the second is the vertex closest to ( ∞, ∞, ∞ )

v1

public Point3d v1()

Get the first vertex

Returns:

the first vertex

v2

public Point3d v2()

Get the second vertex

Returns:

the second vertex

v3

public Point3d v3()

Get the third vertex

Returns:

the third vertex
