Can somebody explain what is the difference between this two functions. Don't they represents the same thing for multiple textures.
In the MultiTextureTest, I replaced the

geom.setTexCoordData( 1, geom.getTexCoordsData( 0 ) ); to
geom.setTextureCoordinates( 1, 0, gc.getTextureCoordinates2f() );

and the both look the same.

Code:

    {
        final int features = Geometry.COORDINATES | Geometry.TEXTURE_COORDINATES ;

        GeometryConstruct gc = Cube.createGeometryConstructTA( 0.3f, features, false, 2 );
        TriangleArray geom = new TriangleArray( gc.numVertices() );
       
        geom.setCoordinates( 0, gc.getCoordinates() );
       
        geom.setTextureCoordinates( 0, 0, gc.getTextureCoordinates2f() );
       
       //geom.setTexCoordData( 1, geom.getTexCoordsData( 0 ) );       
        geom.setTextureCoordinates( 1, 0, gc.getTextureCoordinates2f() );
       
        return ( new Shape3D( geom, app ) );
    }

The difference is memory consumption and the ability to modify the tex-coords of TU 0 and TU 1 without affecting each others.

geom.setTexCoordData( 1, geom.getTexCoordsData( 0 ) ); to

This assigns the float buffer of TU 0 to TU 1 (no copy).

geom.setTextureCoordinates( 1, 0, gc.getTextureCoordinates2f() );

This copies the data from the passed buffer to TU 1.
