What is the relationship between slitscan -- a filmmaking technique used for the Stargate sequence in Stanley Kubrick's 2001, the going to hyperspace effect in SW, the dopplered star effect in Trek -- and Morse Theory? https://en.wikipedia.org/wiki/Morse_theory https://www.youtube.com/watch?v=qKOAOzVHvFQ&t=1157s /VFX History: Slit Scan/ by ShiveringCactus: VFX from the video description: How did 2001: A Space Odyssey, Star Wars, Doctor Who and Star Trek: The Next Generation create mind-bending visuals decades before CGI? The secret is Slitscan, a terrifyingly complex technique that literally turns time into space. In this deep dive into VFX history, I explore the origins of the Slitscan technique. From its humble beginnings in 19th-century "strip photography" used for horse racing and mapping, to the genius of John Whitney and Douglas Trumbull, we look at how a mechanical slit, a long-exposure camera, and patience created the most iconic "trippy" visuals in cinema.
