SilverLining::Atmosphere *  atmosphere 
) const
protectedvirtual

Copy the depth buffer from the currently bound frame buffer to a texture that the clouds can use for smoothing clouds near other objects. Returns true if the depth texture was actually updated and bound.

virtual bool makVrv::DtCloudDrawable::anyLayerNeedsDepthTexture ( void  ) const
protectedvirtual

Whether any cloud layer needs the depth texture (e.g. stratocumulus always needs it)

virtual void makVrv::DtCloudDrawable::unbindDepthTexture ( osg::RenderInfo &  renderInfo) const
protectedvirtual

After the drawable is done with the depth texture we need to unbind it so SLI is fast.
