5-2-1-8 3D Rendering
The 3D (volume) rendering is a calculation process to visualize certain 3D-structures of a scanned 
volume by means of a 2D-image. The gray value for each pixel of the 2D-image is calculated from the 
voxels along the corresponding projection path (analyzing beam) through the volume. The render 
(calculation) algorithm, surface or transparent mode, determines how 3D-structures are visualized.
