Method Detail

read

public static PgJvxSrc read(java.lang.String fileName)

Read geometry file in Geometry Center's OFF file format.

read

public static PgJvxSrc read(java.io.BufferedReader in)

Read geometry file in Geometry Center's OFF file format.

parse

protected static PgJvxSrc parse(java.io.BufferedReader bufReader)

write

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

Write a geometry into a string in OFF file format. 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.

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,
                                                PdVector[] elementNormal)

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.
