Hi,
I'm currently experimenting with a 2D Canvas and rendering everything to
a texture. For this I use FGODGauge to render to texture and
FGODGauge::set_texture to replace a texture in the cockpit with the
texture from the fbo. This works very well unless I enable any effect
which causes the texture to be replaced by the original one.
I have just extended the ReplaceStaticTextureVisitor::apply(osg::Geode&
node) method to also replace texture inside effects:
virtual void apply(osg::Geode& node)
{
simgear::EffectGeode* eg =
dynamic_cast<simgear::EffectGeode*>(&node);
if( eg )
{
osg::StateSet* ss = eg->getEffect()->getDefaultStateSet();
if( ss )
changeStateSetTexture(ss);
}
else
if( node.getStateSet() )
changeStateSetTexture(node.getStateSet());
int numDrawables = node.getNumDrawables();
for (int i = 0; i < numDrawables; i++) {
osg::Drawable* drawable = node.getDrawable(i);
osg::StateSet* ss = drawable->getStateSet();
if (ss)
changeStateSetTexture(ss);
}
traverse(node);
}
Does anyone know how I can correctly replace a texture, such that it
also stays there if effects are enabled (eg. generic effect).
Thanks,
Tom
