various problems with vtk

[antonio.giurini at lycosmail.com]

Hi,

1) I'm using vtk 2.0 and I've some problems whith memory allocation and memory leaks.
Do you know if there are problems with vtk's reference counting?


2) I'worked with vtkTubeFilter an I think I've discovered a little bug (vtk 2.0) in void vtkTubeFilter::Execute():

      if ( inScalars ) // varying by scalar values
        {
	/* VTK 2.0 version: "inScalars->GetScalar(****j*****)"
	it works only if inLines describes 1! polyline
        sFactor = 1.0 + ((this->RadiusFactor - 1.0) * 
                  (inScalars->GetScalar(j) - range[0]) / (range[1]-range[0]));
	*/
	// New :
       sFactor = 1.0 + ((this->RadiusFactor - 1.0) * 
                  (inScalars->GetScalar(pts[j]) - range[0]) / (range[1]-range[0]));
	
	if ((range[1] - range[0]) == 0.0)
	  {
	  vtkErrorMacro(<< "Dividing by zero");
	  }
        }

Thanks, Antonio
