are you worked it out?

If you modify the third parameter of FFTOceanSurface which is called numTiles
you will be able to increase the number of tiles that make up the ocean surface
and thus the range. Increasing the number of tiles will have a direct effect on
performance. You may wish to try the new vbo technique in
can you explain more in details this please ?

LOD - Level Of Detail. Obviously when you build a terrain database, you
build it in few different level of details. What is close is more detailed
what is further is less detailed. All of the terrain generation tools are
aware of this and they build the final scene graph using LODs. They often
Hi nick and thanks for your support ;)
i can investigate for your suggestion about lod node , shape files integration
... etc
but for now i have a simple question :
can i simply increase the ocean grid size surface ? if yes how ?
my terrain is built like i said with vpb using srtm elevation
yes. look in the setup code for the oceansurface (I think. Dont have the
code with me at the moment, but as far I can recall you can do that).

I think the endless option will not produce real endless ocean you can see
it from any range. I think it is rather following your eyepoint and render
enough so you can see it all the time. Just my thoughts, might be good to
check it actually

yes from i have read the endless option adapt only the point of view to
simulate endless effect
that's said : how to get endless effect with osgocean especially in high
altitude
thanks and good day

I guess you would need to put some LOD on the ocean culture.

ok another question
how to integrate osgocean into a pagedlod terrain database built with vpb ?
i tried lot of things without success

nice screens !
can you show me your graph structure
i tried every combination : ocean as a child, as a parent of the terrain
parent, in the same level
Hello,
I havent tried with a database built with vpb, but I did it with database
built with TerraVista. The key was to cut out
with osgocean there is an example coming which shows you how to add your own
terrain. in the sample, the file loaded is called island.ive. Mimic the code
and put there your database. That is what I did
