Hi Sebastien,
I am sorry to bother you but did you work or are you still plannning to work on
the aspect we talked in this thread ?
Actually I did implement part of it in my project, and recently merged
the changes back into osgOcean SVN trunk. The change is that the ocean
surface is now under a MatrixTransform called _oceanTransform which is
under the OceanScene, instead of being a straight child.
The problem is that I didn't expose any setter/getter for the
MatrixTransform's Z height in OceanScene. I was getting to it, but
didn't need it quite yet in my own projects, so it was lower on my
priority list. If you want to add it, it should be pretty easy. Here's
what you'll need to do:
1. void setOceanSurfaceHeight(double height)
1a. will set the _oceanTransform to a translation matrix with height
in Z.
1b. will set _isDirty = true;
2. OceanScene::init() will need to set the clip planes for reflection
and refraction to Z = _oceanTransform.getTrans().z() +
_oceanSurface->getSurfaceHeight()
3. Also add a getter double getOceanSurfaceHeight() const that returns
_oceanTransform.getTrans().z()
Once you've done that, you should be able to call
setOceanSurfaceHeight(someValue) and it should work well. Also you could
add keys to the OceanScene event handler to be able to change the
height interactively (perhaps '+' to raise it, '-' to lower would be nice).
Let me know how that works for you, and if you get something that works
well, send me the changes and I'll merge them in.
J-S
