Constructor Details

AbstractObjPolygonReader

protected AbstractObjPolygonReader(Reader reader)

Construct a new instance that reads OBJ content from the given reader.

Parameters:

reader - reader to read characters from

Method Details

isFailOnNonPolygonKeywords

public boolean isFailOnNonPolygonKeywords()

Get the flag indicating whether or not an IllegalStateException will be thrown if the OBJ content contains any keywords defining non-polygon geometric content (ex: curv). If false, non-polygon data is ignored.

Returns:

flag indicating whether or not an IllegalStateException will be thrown if non-polygon content is encountered

setFailOnNonPolygonKeywords

public void setFailOnNonPolygonKeywords(boolean fail)

Set the flag indicating whether or not an IllegalStateException will be thrown if the OBJ content contains any keywords defining non-polygon geometric content (ex: curv). If set to false, non-polygon data is ignored.

Parameters:

fail - flag indicating whether or not an IllegalStateException will be thrown if non-polygon content is encountered

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

readFace

protected PolygonObjParser.Face readFace()

Return the next face from the OBJ content or null if no face is found.

Returns:

the next face from the OBJ content or null if no face is found

Throws:

IllegalStateException - if a parsing error occurs

UncheckedIOException - if an I/O error occurs

handleVertex

protected abstract void handleVertex(Vector3D vertex)

Method called when a vertex is found in the OBJ content.

Parameters:

vertex - vertex value

handleNormal

protected abstract void handleNormal(Vector3D normal)

Method called when a normal is found in the OBJ content.

Parameters:

normal - normal value
