What I've learned is that caffeine metabolism goes down with age and sleep gets lighter with age. Even if you can fall asleep easily, the residual caffeine in the middle of the night is enough to wake you out of light sleep. I made a tool to convince myself to cut back: http://jitterdone.com

A height map can represent voxel data if the columns are integer heights, in the same way an integer can "represent" an infinite number of countable things. It's like saying the number 7 is "related" to a group of 7 ducks. The relationship is kind of meaningless.

But more importantly height maps can use also floating point heights in which case there's no reasonable mapping between the two. So your statement isn't generally true.

> Such maps limit the terrain to “one height per position on the map” - Complex geometries such as buildings or trees are not possible to represent.

FWIW I'm working on a voxel sandcastle game. People usually seem particularly surprised by this style because they're so used to such games being rendered by height maps which don't allow tunnels or arches or overhangs.

You don't have to correct it dozens of times a day!? Really?

In high school because people thought I was a snob or something because of my social awkwardness. I love talking to people but absolutely hate initiating conversations. I love looking people in the eye when they're talking and hate looking at people as a I pass, so I usually don't even know who is walking near me. It's kind of crippling (and this is after it's gotten much better over time).
