I saw Leetify's map control proof of concept ages ago and thought it was so cool. (https://reddit.com/r/GlobalOffensive/comments/1k6v51e/map\_control\_visualized\_3x\_speed\_calculated\_based/) I was super inspired by their post so I took a crack at my own version of it, except one that actually runs on any demo in real time instead of being a render!
The round shown is the full round 16 of Liquid vs Vitality! It is rendering real time at 1x speed.
The shading is the territory each side controls, worked out from player positions, what they can see (based on map geometry and ray casting), and the map geometry. Solid means someone's holding it with their position or staring at it with a gun out. Hatched is space behind an entry they're watching, so nobody's getting in without going through them. It only fills in once they've held that watch for a couple of seconds, and it starts to clear out the moment they stop watching.
