[vtkusers] Re: update window display

Hi All,

Would anybody please shed some light on this?

I am working on a simple win32 application to cycle through axial images.
The input is a series of DICOM file read by ITK reader, and exported to VTK.
VtkExtractVOI is used to get the 2D data. vtkWin32OpenGLRenderWindow is
used. In my mouse callback, I change the VOI data, and call
renderwindow->Render() to update the display.

Problem: I can never see more than 10 slices. After 9, I got empty screen. I
change to use vtkReslice, and had the same problem. Can only see like 5

Question: what I am supposed to use to update image? Is the Render( ) method
working in a separate thread, and I have to copy image data to the window

Thanks in advance,
