My last two posts covered some of the challenges posed by the roundness and size of the world, and the amount of data required to represent the world. I've had a few ideas on that last point, compact representation of the world, that I'll develop further in a future post. There are several published approaches as well, and some of my ideas parallel or draw from them. I hope to have a reading list tomorrow and maybe a decent description of my ideas.
For now, I need to call it a night. It was a long night doing Christmastime stuff, and I'd like to get up at a reasonable hour tomorrow to do yardwork and maybe get the house into a bit better shape.
