Hello Bart,
Is there a way to setup osgOcean such that each time viewer.frame() is called,
it only progresses a fixed time step?
See here:
http://code.google.com/p/osgocean/source/browse/trunk/include/osgOcean/FFTOceanTechnique#351
By default, osgOcean updates its ocean technique using real elapsed
time, but you can use OceanAnimationCallback to give it whatever
simulation time you want. You just override the operator() and in it,
call update(..., mySimTime), like this:
class MyOceanAnimationCallback : public
osgOcean::FFTOceanSurface::OceanAnimationCallback
{
public:
MyOceanAnimationCallback () {}
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
double simulationTime = ...; // get simulation time
update(node, nv, simulationTime);
}
};
And set it on your ocean surface like this:
oceanSurface->setOceanAnimationCallback(new MyOceanAnimationCallback);
I implemented this feature because we do networked simulations on
multiple machines, and this allows us to synchronize the animation of
the ocean on all machines given a synched simulation time value that is
propagated on the network.
Hope this helps,
J-S
