• Z-buffering is an image space algorithm.

• Algorithm:

  for each polygon P
  
  {for each pixel (x, y) in P 
  
  {compute z_depth at x, y
  
  if z_depth < z_buffer (x, y) then
  
  set_pixel (x, y,color) 
  
  z_buffer (x, y) <= z_depth}}
  

• The algorithm is usually applied to scenes containing polygon surface, because depth …
