Method Detail

read

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

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

The returned array of geometry may contain keyframes of an animation. This is checked with the method isAnimation().

Alternatively, one may call load(BuffereredReader) followed by getGeometries() resp. getAnimations() to have a finer control about which information one wants to use from a source. For example, optional display information must be retrieve by a subsequent call getDisplayOption() if available.

Specified by:

read in interface PgLoaderIf

Overrides:

read in class PgAbstractLoader

Parameters:

in - BufferedReader to read textual data from.

Returns:

Array of JVX geometries.

write(Writer, PgJvxSrc [])

Author:

Konrad Polthier

Version:

18.11.01, 1.20 revised (kp) Parsing of polygons improved.
10.06.01, 1.10 revised (kp) Return an array instead a single geometry.
20.02.01, 1.00 created (kp) Method body from former version read(String fileName).

write

public boolean write(java.io.Writer writer,
                     PgJvxSrc[] geomArr)
              throws java.io.IOException

Write an array of geometries into an output stream writer.

Numbers with absolute value less than jv.vecmath.PuMath#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.

Specified by:

write in interface PgLoaderIf

Overrides:

write in class PgAbstractLoader

Parameters:

writer - Write all data to this stream

geomArr - Array with geometries to save

Returns:

true on success.

Throws:

java.io.IOException

See Also:

read(BufferedReader)

Version:

10.06.01, 1.10 revised (kp) Save array of geometries instead of single geometry.
