Summary:                    The stereo image for vtkOpenGLGPURayCastMapper can't
render correctly.
Description: 
Dear All:

  The image 1 is the DICOM test image.

  When i use vtkFixedPointVolumeRayCastMapper to render, the stereo image has 
  the terrific effect.The result shows in image 2.

  However, when using vtkOpenGLGPURayCastMapper, the depth effect disappeared 
  and the stereo effect looks bad.

  To examine the image 3, i found that the image 3 and image 2 are not the same.
  In image 2, the related position of the blue and red block in the front is 
  opposite to the back.
  In image 3, the related position in the front is the same with the back.

  Otherwise, there is a curious phenomenon at the left-top corner.
  The stright line is turned to other direction.   


  Theoretically, the image 2 must the same with image 3.
  i guest the problem is result from GPU render mapper.
  What can i do to solve this problem???

Thanks...
