  +--jv.loader.PgObjLoader

All Implemented Interfaces:

PgLoaderIf

public class PgObjLoader

extends java.lang.Object

implements PgLoaderIf

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 webpage on supported file formats.

Constructor Detail

PgObjLoader

public PgObjLoader()

Method Detail

getDisplayOption

public PvDisplayOption getDisplayOption()

Get display options which some parsers and geometry file formats supply. This geometry file format does not support loading/saving of display options.

Specified by:

getDisplayOption in interface PgLoaderIf

setDisplayOption

public void setDisplayOption(PvDisplayOption option)

Set the display options to be saved within the geometry file. This method must be called before writing the geometry. This geometry file format does not support loading/saving of display options.

Specified by:

setDisplayOption in interface PgLoaderIf

isAnimation

public boolean isAnimation()

Determine if currently loaded data is an animation.

Specified by:

isAnimation in interface PgLoaderIf

setAnimation

public void setAnimation(boolean flag)

Set flag whether current geometry data is an animation.

Specified by:

setAnimation in interface PgLoaderIf

read

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

Read geometry file in Wavefront's OBJ file format.

read

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

Read geometry file in Wavefront's OBJ file format.

Specified by:

read in interface PgLoaderIf

Following copied from interface: jv.loader.PgLoaderIf

Parameters:

in - BufferedReader to read textual data from.

Returns:

Array of JVX geometries.

#write(Writer)

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 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.

Specified by:

write in interface PgLoaderIf

Parameters:

writer - Write all data to this stream

geomArr - Array with geometries to save

Returns:

true on success.
