It would be nice to have a Heatmap for the entire map. The heatmap would indicate how hot/cold any tile on the map would be. This would mean that snowforts would need heating etc. What do you think?

[nogoodnames]

It would take up a ridiculous amount of processing power for dynamic heating. I think Toady mentioned something like this on the meetup livestream, where magma would heat up the surrounding tiles. I think his idea for solving the processing issue was to have the heat level for each tile achieve stability in a static environment and only do calculations when something is changing. So yeah, heating might be added but there probably won`t be any simulated weather systems any time soon due to the difficulties with processing so much information.

But really it would lnly be about 150x150x150x10 calculations per step.

'only?' (I assume)

Remember you also need to calculate for every tile everywhere, even the underground hidden ones, more like (width of map) x (length of map) x (height of map)

While the height is variable and I do not know the precise width and length of embarks. Even if it was a small 100x100x100 embark you reach 1,000,000 calculations per tick keep in mind that it takes an average dwarf 10 ticks to move one step. That's 10,000,000 calculations per step. Considering that 100x100x100 is a very small embark at best, the glacier won't be the only thing frozen.

if he posted on that thread, somebody would accuse him of "necroing" it.

The people on this message board need to reach some kind of concensus...

Either way, he added nothing new to the discussion.

Consensus -
Bringing back an old topic to say OMG this is cool! = Necro
Bringing back an old topic while adding something = Not - Necro
Suggested before = Didn't read forum guidelines

[tHe_silent_H]

pretty sure necroing is considered fine, if you have something meaningful to add to it.

besides we'll be able to be necromances next release, we need all the practice we can get!

We could make a giant 3d bitmap to represent the heatmap, where you only check the temperature of the squares with objects on them, or where something is happening. The problem is still that it would be mighty slow to calculate convection, conduction and radiation of heat from a heat source, especially things like boiling water.

Another way to do it is to have zones, like sets, and within those you have sub-zones, like subsets.
