hi all,
in my application, i use vtkVolumeRayCastMapper to implement
ray-casting. i have succeeded in implementing raycasting using volume
data,  but when i use dicom file as input source,  one error occurs
ERROR: In .\vtkVolumeRayCastMapper.cxx, line 326
vtkOpenGLVolumeRayCastMapper (01C0CCF0): Cannot volume render data of
type short, only unsigned char or unsigned short.

how can i do? should i convert dicom file to another format first?
