Handling land below sea level
« on: January 28, 2014, 02:00:32 pm »

Hi all,

I'm curious, will the engine be able to handle land that's below sea level, but is not flooded (polders and such)? I live in the Netherlands, a significant part of which lies below sea level, but is protected by dikes and other measures.
In Outerra (Anteworld) that part of the Netherlands is currently just flooded, because only elevation data is used.

Will there be a solution for this type of situation in the future?

 I think, that comes with rivers and seas - had to be as an exceptional area from global water level ... may take some while.

Right, will come with the lakes - polygons that specify a custom water level, can push it up or down.

I am also interested in this implementation; I am from another part of your Europe, which is below-sea-level
(in the 0,-10 feet range); and it looks like it was water-flooded by the engine.

In the attached screenshots, you can see a big river delta (top-right feature), affected by flooding,
and the other affected area (we are just 100 km south of Venice here); also, what is the white-ish stuff?
beach/sandstone procedurally generated?

As a side note, also in the screenshot: the engine behaves quite well under wine!

Interesting, it didn't work last time I tried! ggraz, what driver are you running? I'll try it again on my Intel HD 4000 as soon as i can.

I have wine-1.7.13 with a 32-bit prefix and a nvidia gts450 with blob driver 304.119 ; the output from the engine is

The last DEBUG message I also get in a dialog box before the window opens, yet it seems to be no problem.

Mmh, so that's a different beast to what I have... I have only gl 3.3 core profile here, and 3.1 compatibility. Cameni, is that enough theoretically?

3.3 core should be enough, but I guess a lot will depend also on the quality of the drivers. Hm, but I think we are setting the compatibility profile now ... there was some problem with core on some drivers, even though we are using core for development.

Well, Mesa has an environment variable to override the advertised supported gl version, so i can make outerra think it can create a 3.3 compatibility profile i guess, and as long as it doesn't actually use any compatibility thing it should work™.
