Hello,
this mail only about my customs use vtkSmartPointer
I think many people declare vtkSmartPointer<vtkXXX> like this
vtkSmartPointer<vtkPoints> m_points;
vtkSmartPointer<vtkFloatArray> m_volcolors;
vtkSmartPointer<vtkUnsignedCharArray> m_colors;
vtkSmartPointer<vtkPolyData> m_polydata;
vtkSmartPointer<vtkOrientationMarkerWidget> m_AxesWidget;
...
and
"new" vtkobject like this
m_points = vtkSmartPointer<vtkPoints>::New();
m_volcolors = vtkSmartPointer<vtkFloatArray>::New();
m_colors = vtkSmartPointer<vtkUnsignedCharArray>::New();
m_polydata = vtkSmartPointer<vtkPolyData>::New();
m_AxesWidget = vtkSmartPointer<vtkOrientationMarkerWidget>::New();
....
but I often use template function like this
to "new" vtkobject
template <class T>
void vtkSmartNew(vtkSmartPointer<T>& Ptr)
{
Ptr = vtkSmartPointer<T>::New();
assert(Ptr.GetPointer() != 0);
}
vtkSmartPointer<vtkPoints> m_points;
vtkSmartNew(m_points);
because I think vtkSmartPointer<vtkOrientationMarkerWidget>
is so long, I use ctrl+c ctrl+v so many times to copy type
I think maybe vtk can provide some function like this on "vtkSmartPointer.h"
