5. Algorithms   

The following is covered:

       Development.  
       The colour shaded image.  
       Object Representation.  
       Speeding Things Up  
       Data structures for 3-D objects.  
       Visual Realism.  
       Other Hidden Line/Surface algorithms.  
       Shading.  
       Z-Buffers.  
       Scanline Algorithm  

These 3-D concepts are very important in areas of visualisation.
