[vtkusers] Problem with animating through Add-Remove Actor

[richard.jurkovic at vi-motion.de]

 Hi all,

I'm making some animation tools, which read data for different position from
acsii file (coordinates file), exactly I'm reding only first position and
then
I compute others position (others coordinates). I simulate something like a
gear-wheel.
I declared
vtkActor *m_pActorB2DOutside[NUM_STEPS];
for ( i = 0; i < NUM_STEPS; i++ )
    m_pActorB2DOutside[i] = vtkActor::New();
where NUM_STEPS is for example 360 and actor is global variable
then localy I did inside loop
{
vtkPoints *l_pPointsB = vtkPoints::New();

vtkCellArray *l_pLinesB = vtkCellArray::New();

vtkPolyData *l_pPolyDataB = vtkPolyData::New();

vtkPolyDataMapper *l_pMapperB = vtkPolyDataMapper::New();

l_pPointsB->InsertPoint( j, l_coord.x, l_coord.y, l_coord.z );

l_pPolyDataB->SetPoints( l_pPointsB );

l_pPointsB->Delete();

then for cells (contour for wheel)

l_pLinesB->InsertNextCell( 2 );

l_pLinesB->InsertCellPoint( l_pIdxB[j] );

l_pLinesB->InsertCellPoint( l_pIdxB[j+1] );



l_pPolyDataB->SetLines( l_pLinesB );

l_pMapperB->SetInput( l_pPolyDataB );

l_pMapperB->ScalarVisibilityOff();

m_pActorB2DInside[i]->SetMapper( l_pMapperB );

l_pLinesB->Delete();

l_pMapperB->Delete();

l_pPolyDataB->Delete();

}

in rotating thread I only simply Remove actor last actor and AddActor last
actor +1

m_pRenderer->RemoveActor( m_pActorB2DInside[i] );

m_pRenderer->AddActor( m_pActorB3DInside[m_nLastStep] );

it works good, only my big problem is that the aplication is using still
more memory, then it start to swap ....

I don't understand this process and can't find nothing about how to solve
it.

Can anybody help me?

May be I'm using wrong way for animating, don't know.

Thanks

Richard
