Dear all, This is a slightly delayed response, I have to admit I am longer actively following this mailing list.
A few years I posted my work on river rendering as a submission for the osgOcean project. Unfortunately I do not have the time to maintain this project but maybe I can at least respond to some issues.

Since then new versions of osg, opengl and drivers have been released and either of these might cause issues. Perhaps reverting to a previous environment might shed some light on the exact problems.

It does appears that the original download location is no longer working, thanks for making your copy available. kcbale wrote: > > I can answer your first question. osgRiver was never integrated into the > trunk because I felt that the way it had been combined in its current state > needed some work and sadly I simply haven't had time to work on it.

Much of the water shader code is shared between osgOcean and osgRiver but the water surface is represented and animated in an entirely different way. This creates compatability issues, especially on transition areas between ocean and river. Perhaps some blending scheme could be investigated but this is not a trivial problem to solve and unfortunately I do not have the time to do this. Because osgRiver hasn't been maintained for over three years I don't think it should be considered as a ready to use library in its current form. However, anyone interested in river rendering in osg could definitely use it as a starting point. Anyone interested in a high level overview on the techniques used in osgRiver could glance over the poster: graphics . tudelft . nl / ~ruben / PosterI3D2010 . pdf Kind regards, Quintijn Hendrickx ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=56780#56780 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
