Class PgAbcLoader

java.lang.Object

jv.loader.PgAbstractLoader

vgp.tutor.loader.PgAbcLoader

All Implemented Interfaces:

PgLoaderIf

public class PgAbcLoader
extends PgAbstractLoader

Loader for geometry files given in a user defined file format.

In JavaView the file name convention is that Abc is replaced with a user defined file name extension of three characters.

Method Detail

write

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

Write an array of geometries into an output stream writer.

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:

07.03.03, 1.10 revised (kp) Index of first vertex is used.
09.11.01, 1.00 created (kp)

read

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

Read an ABC geometry file and return an array of new geometries.

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.

See Also:

write(Writer, PgJvxSrc [])

Author:

Version:

10.06.01, 1.10 revised (kp) Return an array instead a single geometry.

getFirstVertexIndex

public int getFirstVertexIndex()

Vertices are assigned an index starting at the given value. Default index counting starts at 0. For example, OBJ, OFF and JVX use index counting [0, numOfVertices-1] while BUY use indices in the range [1, numOfVertices].

The faces of a mesh are defined by referencing the vertices of a face by their index.

Returns:

index of first vertex

Since:

JavaView 2.81.000

Version:

setFirstVertexIndex

public void setFirstVertexIndex(int index)

Vertices are assigned an index starting at the given value. Default index counting starts at 0. For example, OBJ, OFF and JVX use index counting [0, numOfVertices-1] while BUY use indices in the range [1, numOfVertices].

The faces of a mesh are defined by referencing the vertices of a face by their index.

Parameters:

index - index of first vertex
