/* 

	Example showing how to retrieve the newly created operator

	when ApplyOp is called on a single object

*/

// Create primitive

oCube = activesceneroot.addgeometry( "Cube", "MeshSurface" );

// Call command to apply a Taper deformer and 

// retrieve the newly created operator

oColl = ApplyOp( "Taper", oCube, 3, 0, null, 0 ) ;

// Because there is only 1 input object (oCube)

// we know there is only one operator created

var oOp = oColl(0);

// Modify the Amplitude Parameter

oOp.ampl = 0.25 ;

// Create empty collection to store objects that

// we want to apply the operator to

oInputCollection = XSIFactory.CreateObject( "XSI.Collection" );

// Create primitive

oInputCollection.add( activesceneroot.addgeometry( "Cube", "MeshSurface" ) );

oInputCollection.add( activesceneroot.addgeometry( "Sphere", "MeshSurface" ) );

// Call command to apply a Taper deformer and populate collection with its return value

oOps = ApplyOp( "Taper", oInputCollection, 3, 0, null, 0 ) ;

// Validate result

for( var i=0; i < oOps.count; i++ )

{

// Get operator

oOp = oOps(i);

logmessage( oOp.fullname );

}

//Expected results:

//INFO : cube.polymsh.taperop

//INFO : sphere.polymsh.taperop
