Method Detail

read

public static PolygonalMesh read(java.lang.String fileName,
                                 Vector3d scale)
                          throws java.io.IOException

Creates a PolygonalMesh based on MDL data contained in a specified file. The node coordinate data can be scaled non-uniformly using an optional parameter giving scale values about the x, y, and z axes.

Parameters:

fileName - path name of the MDL file

scale - if non-null, gives scaling about the x, y, and z axes

Returns:

created polygonal mesh

Throws:

java.io.IOException - if this is a problem reading the file

read

public static PolygonalMesh read(java.io.Reader reader,
                                 Vector3d scale)
                          throws java.io.IOException

Creates a PolygonalMesh based on MDL data read from a Reader. The node coordinate data can be scaled non-uniformly using an optional parameter giving scale values about the x, y, and z axes.

Parameters:

reader - the Reader which references MDL data to be read

scale - if non-null, gives scaling about the x, y, and z axes

Returns:

created polygonal mesh

Throws:

java.io.IOException - if this is a problem reading the file

write

public static void write(PolygonalMesh mesh,
                         java.lang.String filename,
                         java.io.PrintWriter pw,
                         NumberFormat fmt)

Writes the specified mesh to a PrintWriter, using the MDL file format. Vertices are printed first by x, y, and z coordinates. Normals are printed next by x, y, and z coordinates. Faces are printed next by a list of integers which gives the indices of that face's vertices in counter-clockwise order followed by the indices of the vertex normals.

The format used to print vertex coordinates is specified by a C printf style format string contained in the parameter fmtStr. For a description of the format string syntax, see NumberFormat.

Parameters:

mesh - polygonal mesh to write to file

pw - PrintWriter to write this mesh to

fmt - format for writing the vertex coordinates

writePoints

public static void writePoints(Point3d[] pnts,
                               java.lang.String filename,
                               java.io.PrintWriter pw,
                               NumberFormat fmt)
