Constructor Detail

public PgDxfLoader()

Method Detail

read

public PgJvxSrc[] read(java.lang.String fileName)

Read geometry file in Autodesk DXF file format.

read

public PgJvxSrc[] read(java.io.BufferedReader in)

Read geometry file in Autodesk DXF file format.

parse

protected PgJvxSrc[] parse(java.io.BufferedReader bufReader)

write

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

writePdVectors

protected static java.lang.String writePdVectors(java.lang.String type,
                                                 java.lang.String id,
                                                 int num,
                                                 PdVector[] vector)

Write list of double vectors into string. Numbers with absolute value less than EPS are shown as zero. This avoids the annoying 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.

writePolygons

protected static java.lang.String writePolygons(int num,
                                                PiVector[] polygon)

Write list of polygons and polygon 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.
