Rendering the skin using VTK

I am developing an application in开发者_StackOverflow社区 windows forms that reads a sequence of 2d dicom images and transform them into a 3d object. I can do it pretty well for bones using the VTK framework, but when trying to do the same for the skin, I am getting a blank screen. Does anyone have the same issue? Thanks in advance.

Have you tried changing the rendering image's Window Width and Level in accordance with the calibrated Hounsfield Units?

Are you using vtkPievewiseFunction in the vtk rendering pipeline? Add points to it where (x,y)

• x = hounsfield unit for the organ, y = 1.0f
• x = -10,000, y = 0.0f
• x = +10,000, y = 0.0f

You'll have to refine the algorithm, but that should get you started.
