Class PgObjLoader

java.lang.Object

jv.loader.PgAbstractLoader

jv.loader.PgObjLoader

All Implemented Interfaces:

PgLoaderIf

public final class PgObjLoader
extends PgAbstractLoader

Loader for geometry files given in Wavefront's OBJ file format. This reader supports a subset of the commands, similar to the subset supported by Java3d. For details see the web page on supported file formats.

Method Detail

read

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

Read geometry file in Wavefront's OBJ file format.

Author:

Konrad Polthier

Version:

20.02.01, 2.00 revised (kp) Method body moved to read(BufferedReader).
04.03.00, 1.50 revised (kp) Argument geometry removed, just fill private arrays.
00.00.98, 1.00 created (kp)

read

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

Read geometry file in Wavefront's OBJ file format.

Specified by:

read in interface PgLoaderIf

Overrides:

read in class PgAbstractLoader

Parameters:

in - BufferedReader to read textual data from.

Returns:

Array of JVX geometries.

See Also:

PgAbstractLoader.write(Writer, PgJvxSrc [])

Author:

Konrad Polthier

Version:

20.02.01, 1.00 revised (kp)
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

read(BufferedReader)

Version:

09.09.02, 2.00 revised (kp) Exchange vn and vt, remove vd vector fields to comply with OBJ format.
10.05.02, 1.30 revised (ep) Save first vector field if existent and vertex based as 'vd'.
10.06.01, 1.20 revised (kp) Save array of geometries instead of single geometry.
22.08.99, 1.10 revised (kp) Number with abs value less than PuMath.EPS are shown as zero.
22.08.99, 1.00 created (kp)
