As you have seen, it was not designed to do that. It's designed to
recalculate the shadow map each frame. I guess you could add a boolean
to it to say that it has been calculated, and then not redo it again...
Maybe just something like:
class myShadowMap : public osgShadow::ShadowMap
{
public:
myShadowMap() : _done(false) {}
virtual void update(osg::NodeVisitor& nv)
{
if (!_done)
osgShadow::ShadowMap::update(nv);
}
virtual void cull(osgUtil::CullVisitor& cv)
{
if (!_done)
{
osgShadow::ShadowMap::cull(cv);
_done = true;
}
}
private:
bool _done;
};
Note that I didn't try this, but it might give you something to start
with? Let us know how it goes.
Hope this helps,
J-S
