public class SimpleMovieIO

extends MovieIO

This class provides a very simple file format for NVisF movies in which each ObjectGroup wraps a PointArray. Basically, it pulls the coordinates and colors from the PointArray and writes them to file, then stuffs them back into a new PointArray on reading. The Appearance is written to a separate file. This is not a proper way to handle movies, but this is intended as a stopgap procedure until the Compressed Geometry methods can be properly debugged.

Constructor Summary

SimpleMovieIO()

Method Summary

ObjectGroup[]	readMovie(java.lang.String inputFileName) Reads a set of ObjectGroups from file.
boolean	writeMovie(ObjectGroup[] frames, java.lang.String outputFileName) Writes the Geometry component of the movie onto a file called 'outputFileName.smv', and the Appearance to a file called 'outputFIleName.apr'.

Method Detail

writeMovie

public boolean writeMovie(ObjectGroup[] frames,
                          java.lang.String outputFileName)
                   throws java.io.IOException

Writes the Geometry component of the movie onto a file called 'outputFileName.smv', and the Appearance to a file called 'outputFIleName.apr'.

Overrides:

writeMovie in class MovieIO

Following copied from class: edu.washington.NVisF.animator.MovieIO

Parameters:

frames - the array of ObjectGroups to write

outputFileName - a String identifying the file to write to

Returns:

boolean true if the write succeeded, false otherwise

Throws:

java.io.IOException - if a write error occurs

java.lang.IllegalArgumentException - if something is wrong with the supplied ObjectGroups

readMovie

public ObjectGroup[] readMovie(java.lang.String inputFileName)
                        throws java.io.IOException

Description copied from class: MovieIO

Reads a set of ObjectGroups from file. The supplied file name is used as a pattern to construct the actual file name, according to the standards of the implmenting class. Most classes will append an extension identifying the file format.

Overrides:

readMovie in class MovieIO

Following copied from class: edu.washington.NVisF.animator.MovieIO

Parameters:

inputFileName - a String identifying the file to read from

Returns:

ObjectGroup[] the frames read from file, or null if something went wrong

Throws:

java.io.IOException - if a read error occurs

java.lang.IllegalArgumentException - if the data is somehow corrupted
