Evaluation of 30m elevation data in Outerra

<< < (7/8) > >>

HiFlyer:
A question I would ask is how much does the increased resolution affect framerate, if at all?

cameni:
I haven't measured it precisely (needs to be a dynamic perf measurement), but it doesn't seem to be affecting anything. It's just that one terrain level is now loaded instead of being generated, but there isn't a big difference, performance-wise.

John514:
Just a thought... if FSX, a sim made in 2006 can use 10m DEM the size of North America (FTX PNW) , why can't  Outerra?

cameni:
PNW isn' t the size of North America, and it's not a 10m mesh. It's LOD10, meaning a 38m mesh.

I see even ORBX is advertising it as 10m, even though the mesh author himself wondered where that misinformation came from.

Now that is interesting! Anyway, whatever orbx uses, it look very good. If it is 38m then things are even better. I think a big part of how orbx scenery looks is due to textures. Is there a way to base the textures in Outerra to satellite photos? I'm not saying to overlay the photos on the terrain but color it based on them instead.
