How did this work on actual DVD players? Was it programmed to never hit a corner or was that a side effect of how it was implemented?

- maxbond 4y agoCan confirm it would hit the corner if you waited long enough. I saw it happen twice, and a third time where it was like two or three pixels off from hitting right in the corner. I'm fairly sure (based on observation/recollection) the logo was placed randomly with a random vector, and when it contacted the wall it's vector was reflected across the normal at that point (eg https://commons.wikimedia.org/wiki/File:Reflection_angles.svg https://commons.wikimedia.org/wiki/File:Reflection_angles.sv...). I'm not sure that every configuration would reach the corner, but many would.
- vikingerik 4y agoIt hits the corner, it's just really rare. If there are 500 possible pixel positions when it hits the edge, then it's only going to hit the corner exactly on 0.2% of bounces.
