1) Problem description:
I need to redraw the vtkRenderer when users click the someplace of window.
Firstly, the all props were deleted:
m_Renderer-&gt;RemoveAllViewProps();

Then, these codes were used to redraw the vtkRenderer

vtkPoints&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; * pts&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = vtkPoints::New();
vtkUnstructuredGrid * aTriangleGrid&nbsp;&nbsp; = vtkUnstructuredGrid::New();
vtkDataSetMapper&nbsp;&nbsp;&nbsp; * aTriangleMapper = vtkDataSetMapper::New();
vtkActor&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; * Actor&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = vtkActor::New();

// some codes to create the Props

m_Renderer-&gt;AddViewProp( Actor );

pts-&gt;Delete();
aTriangleGrid-&gt;Delete();
aTriangleMapper-&gt;Delete();
Actor-&gt;Delete();

Finally, The memory usage was growing with redrawing the vtkRenderer

2) My environment
Windows XP SP2
mingw32-gcc-3.4.5
wxWidgets 2.8.9 linked as dll
VTK 5.0 linked as dll
wxVTKRenderWindowInteractor cvs version (up to now)

I know this problem can be avoided by using linker's /delayload flag of MFC,
but how to fix this problem for mingw?

Thanks a lot!

I would think setting some renderer instance to NULL might help.
(-&gt;SetRenderer(NULL)).
