A longstanding trick in computer graphics is to add fog to a scene. Not only does fog help create a sense of atmosphere, but it also helps to avoid needing to render huge scenes, since everything further than a certain distance away becomes invisible.<\/p>\n
The math behind fog isn’t all that complicated, which is why I was surprised yesterday to realize that a scene I was rendering had the fog exactly wrong: Everything near the camera was obscured by misty white fog, whereas objects far away remained perfectly visible.<\/p>\n
It wasn’t right, but it certainly looked very cool. I could see entire vistas, mountains, streams and villages, with crystal clarity, going far off into the distance, even as nearby objects remained shrouded in mist.<\/p>\n
I pored over my code, trying to understand where I had gone wrong, but couldn’t seem to find the bug. I didn’t actually understand what was going on until later that night, when I woke up in bed, and realized that the entire episode had been a dream.<\/p>\n
So it seems that I program when I dream. I wonder whether that is a good thing. For all I know, I’m a better programmer when asleep.<\/p>\n
But if last night was any indication, I am lousy at debugging in my dreams.<\/p>\n","protected":false},"excerpt":{"rendered":"
