Hi Albert;
You have implemented a SSD(shaded surface display) method. With this 
method you are creating polygonal data, you must create a volume for 
using vtkColorTransferFunction. For seeing vessels and soft tissues, you 
must read about hounsfield unit(to understand the meaning of scalar 
values), VRT(volume rendering technique)(to understand how to create a 
volume from medical image data), vtkVolumeTextureMapper3D(to understand 
how to map a texturizedvolume), vtkImplicitFunction (to understand how 
to set the opacities of scalar values) and vtkColorTransferFunction(to 
understand how to set the colors of scalar values)...I suggest you to 
check the demo version of IQ-VIEW 
for understanding the basics of these medical methods...
