[osg-users] render function using event handler
if (ea.getKey() == '+')
{
_oceanScene-setOceanSurfaceHeight(_oceanScene-getOceanSurfaceHeight() +
1.0);
osg::notify(osg::NOTICE) Ocean surface is now at z =
_oceanScene-getOceanSurfaceHeight() std::endl;
return true;
}
if (ea.getKey() == '-')
{
_oceanScene-setOceanSurfaceHeight(_oceanScene-getOceanSurfaceHeight() -
1.0);
osg::notify(osg::NOTICE) Ocean surface is now at z =
_oceanScene-getOceanSurfaceHeight() std::endl;
return true;
}
}
If I press + water level is increased and for - water level is
decreased
the above code I had written is just setting ocean surface height. now I
need to know which function is called after setting height
using
_oceanScene-setOceanSurfaceHeight(_oceanScene-getOceanSurfaceHeight() +
1.0);
what the osgOCean does to render the ocean with increased or decreased
water level
i tried gdb but cant trace what is happening..
I think some event is triggered after setting OceanSurfaceHeight but dont
know where or how
I hope the developers of osgOcean are viewing this mail and they will
answer my question.
Any pointers are greatly appreciated.
Thanks in advance

Re: [osg-users] render function using event handler
Hi Rashad,
All setOceanSurfaceHeight does is set the matrix of the transform that
parents the ocean surface so that it translates the surface up or down.
Take a look here:
http://code.google.com/p/osgocean/source/browse/trunk/include/osgOcean/OceanScene#224
It also dirties the scene asking for a rebuild on the next update traversal.
Regards,
Kim.

Re: [osg-users] render function using event handler
thanks Kim.
OK. after translate will it update window automatically
what I want is partly done with osgOcean
after increasing height I need to find the area that is under water. Is it
possible is a big question but I have only one question
Is it possile? and how

Re: [osg-users] render function using event handler
It depends how accurate you want your calculation to be.
An approximation would be to simply take the volume of the cuboid that
forms between the seabed and the ocean surface.
If you want a more accurate volume calculation then you'd have to take into
account the shape of the waves and the seabed.
I *think* one of the properties of the FFT ocean surface is that the
average height will always be zero so you can treat it like a flat plane in
your volume calculation. You might want to check that though it's been a
while since I've looked at it in detail. If that's the case you only need
to take into account the shape of the sea bed in your calculation. It is
possible, but you'll have to work out the maths for that.

Kim.
