Talk:Introvision
 | This article is rated Start-class on Wikipedia's content assessment scale. |
This article would benefit from an explanation of the difference between the optical compositing system pioneered for the earlier 2001: A Space Odyssey and Introvision, which the latter seems to resemble.
This article does not in any way attempt to explain how Introvision works
[edit]This article only explains standard front projection. Not in any way how the z-occlusion works, which is really what is interesting and novel about the system. There is no good description that I can find anywhere. Only a scant, confused mention of what seems to be dual focus projection of the image first reflected from the beam splitter and then on to another reflecting mirror. Still doesn’t explain how you get z-occlusion without a precisely cut scotch light screen Frisenette (talk) 01:30, 3 April 2022 (UTC)
