[Insight-users] VectorContainer, removing element

[Laurent Mundeleer]

in fact I think I didn't gave you enough information, here's some code :
...

    typedef itk::FastMarchingImageFilter<Image2DType, Image2DType> 
fastMarchingType;
    typedef fastMarchingType::NodeContainer NodeContainer;
    typedef fastMarchingType::NodeType NodeType;

...
    NodeContainer::Pointer seeds[128];
...
void levelSetITK::addSeed(float *pos, float ratio)
{   
    typedef NodeType::IndexType IndexType;
    IndexType point;

    float ratio0 = ratio*0.969;
    float ratio1 = ratio*0.98;

    point[0] = static_cast<IndexType::IndexValueType>( pos[0]*ratio0 );
    point[1] = static_cast<IndexType::IndexValueType>( pos[1]*ratio1 );
   
    NodeType node;

    node.SetValue( -25.0 );
    node.SetIndex( point );

    int p = (int) pos[2];
    seeds[p]->InsertElement( nbreSeed[p], node );
    nbreSeed[p]++;
}

and I'd like to remove some element from seeds.

Thanks

Laurent
