Member Function Documentation

makVrv::DtChannelSpecificGroup::META_Node	(	vrvOsg	,
		DtChannelSpecificGroup
	)

virtual void makVrv::DtChannelSpecificGroup::addChannel ( DtChannel *  channel )

virtual

Add channels that should draw the things under this group node.

virtual void makVrv::DtChannelSpecificGroup::removeChannel ( DtChannel *  channel )

virtual

Remove a channel causing things under this group node to be culled from this channel.

virtual int makVrv::DtChannelSpecificGroup::numChannels ( ) const

virtual

Returns the number of channels that are accepted by the node.

virtual void makVrv::DtChannelSpecificGroup::traverse ( osg::NodeVisitor &  nv )

virtual

traverses the group, checking in the case of a culler, if the channel is allowed to render these objects

virtual void makVrv::DtChannelSpecificGroup::addView ( osg::View *  viewToAdd )

virtual

Although the interface implies that these groups cull by channel, what they REALLY do is cull based on the osg::View associated with the camera associated with a channel.

This method lets you add an osg::View directly to allow traversal that's not necessarily related to a channel render pass

virtual void makVrv::DtChannelSpecificGroup::removeView ( osg::View *  viewToRemove )

virtual

Remove a previously added view.
