[vtkusers] why I can't see the 3D model?

[zhuo Chen]

My program is to realize the conversion from 2D
medical images(JPEG images) to 3D model.I used
vtkMarchingCubes class.The source JPEG images' size is
512*512 and the total number of the images is 195.But
the result of my executalbe program is only an
interact interface.No model can be seen.The accessory
is a part of my program source codes.Who can help me
search the errors?Thank you!
