3D Visualization

After segmentation, the choice of which rendering technique to use must be made. The more traditional surface-based methods first create an intermediate surface representation of the object to be shown. It may then be rendered with any standard computer graphics method. More recently, volume-based methods have been developed which create a 3D view directly from the volume data. These methods use the full gray-level information to render surfaces, cuts, or transparent and semi-transparent volumes. As a third way, transform-based rendering methods may be used.
