What is missing ?

• Technique
• Processing power 3 Teraflops for 1,024x1,024
  image video rate(PS3 218 Gigaflops -gt x15)
• Material (dynamic)

Future

• Better resolution (HDTV)
• Color (multiple holograms, angular multiplexing)
• Larger (1ftx1ft and beyong)
• Faster (100Hz pulsed laser)
• Reflection geometry (white light illumination)
• Full parallax (square factor)
