Returns the size of this object and it's children on disk for the current StreamVersion parameter.

Specified by:

GetDiskUsed in interface StreamInterface

Overrides:

GetDiskUsed in class Geometry

Parameters:

rkVersion - the current version of the Stream file being created.

Returns:

                  int[] riV)

Get the triangle at given index.

Parameters:

i - index.

riV - int[3] array to contain 3 triangle indices.

GetTriangleQuantity

public abstract int GetTriangleQuantity()

Get the number of triangles.

Returns:

Link

public void Link(Stream rkStream,
        Stream.Link pkLink)

Copies this objects children objects from the input Stream's HashTable, based on the LinkID of the child stored in the pkLink parameter.

Specified by:

Link in interface StreamInterface

Overrides:

Link in class Geometry

Parameters:

rkStream - the Stream where the child objects are stored.

pkLink - the Link class from which the child object IDs are read.

Load

public void Load(Stream rkStream,
