Constructor Detail

PgFeLoader

public PgFeLoader()

Method Detail

read

public PgJvxSrc read(java.lang.String fileName)

Read geometry file in Ken Brakke's Surface Evolver FE file format.

read

public PgJvxSrc read(java.io.BufferedReader in)

Read geometry file in Ken Brakke's Surface Evolver FE file format.

parse

protected boolean parse(java.io.BufferedReader bufReader,
                        PgJvxSrc geom)

Parse a Surface Evolver's .fe file and fill instance variables of this class. This is a helper routine of read.

write

public static java.lang.String write(PgJvxSrc geom)

Write a geometry into a string in FE file format.

writeVertices

protected static java.lang.String writeVertices(int num,
                                                PdVector[] vertex)

Write list of vertices into string. Numbers with absolute value less than EPS are shown as zero. This avoids the anoying fact that double precision numbers fill the whole text area hiding the exponent, which hides their small value.

writeElements

protected static java.lang.String writeElements(int num,
                                                PiVector[] element)

Write list of elements and element normals into string. Numbers with absolute value less than EPS are shown as zero. This avoids the anoying fact that double precision numbers fill the whole text area hiding the exponent, which hides their small value.
