A new terrain mapping tool

Quote from: cameni
Underwater terrain comes with 1km resolution, whereas the land data have 90m or better. When processing oceans, the tool doesn't have to go so deep (in quad-tree hierarchy) as with the land, which results in the quicker processing.

So, when you process the terrain data, are you generating and storing all the qtree levels from 90m resolution down to 1m resolution (or whatever its the lower resolution) ?

No, it goes the other way. When processing the terrain data, we are mapping and storing all the quad tree levels from 90m (or 1km in oceans) resolution up to coarser resolutions, ending with 40km one, I think. Detail finer than the stored one is generated in run time using fractals.

(As you may remember, I havent been around for a while) I love these technical blogs, even and especially when they are over my head, gives me reason to read up on new material :-)

Keep it up!
