comment Spawning units in a world made by Perlin noise?
Your revision doesn't help. Two points on a convex curve will never have a legal straight line between them, period. More divisions won't help.

comment Spawning units in a world made by Perlin noise?
This doesn't work. Look at the bottom right, specifically the blob in the red area. It's entirely convex so there's no change to cause another color to be used but clearly no straight line exists from the bottom of the red on the right edge to the rightmost part of the red on the bottom edge.

comment How'd they do it: Millions of tiles in Terraria
@MindWorX: Doing all the updates when it reloads wouldn't always work--suppose you have a whole bunch of barren area and then grass. You go away for ages and then walk towards the grass. When the block with the grass loads it catches up and it spreads in that block but it won't spread into the closer blocks that are already loaded. Such things progress MUCH slower than the game, though--check only a small subset of the tiles in any one update cycle and you can make distant terrain live without loading down the system.

comment How to calculate falling and accelerating velocity?
@Beska: Your rocket engine isn't limited in acceleration, it's limited in thrust. The ratio of thrust/acceleration will change as the tanks get used. A rocket with full tanks is a lot less responsive than one that's nearly empty.

comment How to calculate falling and accelerating velocity?
@Patrick Hughes: Shuttle gross weight: 240,000lb. Total liftoff weight: 4,500,000lb. Admittedly, that includes 58,500 pounds of tank & 400,000lb of SRB. Still, though, you'll get more than 10x the acceleration from the last pound of fuel than from the first.

comment How to calculate falling and accelerating velocity?
@Patrick Hughes: The amount of fuel carried by any true rocket lander (I'm not counting the Mars aerobrake/rocket hybrid cases) is a substantial portion of it's total weight. Assuming the fuel:acceleration ratio to be fixed will produce a very wrong answer.

comment How to calculate falling and accelerating velocity?
@daemonfire300: You misunderstand--I'm not talking about the effect of running out of fuel, but the effect of burning fuel. A constant throttle setting on your engine produces a continuously climbing acceleration figure, a constant acceleration produces a continuously declining fuel burn rate. This means the simple calculations that FxIII gives will produce incorrect fuel use numbers.
