Classes
class	Buffer
	Contains all the regional nodes for a single memory block so each can be redraw independantly. More...
struct	BufferInfo
class	DtRegionalGeodeInfo
	Regional nodes are a simple way to spatially index the geometries into separate osg nodes so they can be effectively culled. More...

Detailed Description

This model draws lines in the scene using data pulled from the kynapse shared buffer.

Note that this object will draw whatever is in the kynapse shared buffer on the local machine, i.e. there is no synchronization across machines.

Member Function Documentation

virtual void makVrf::DtKynapseLinesModel::init ( std::string &  str, bool  useLocalCoord = false  )

virtual

Initialize.

Parameters

str	The name of the shared queue
useLocalCoord	If set to true, the system shall assume the network data is set to local. Otherwise a netToLocal conversion is done before drawing.

virtual void makVrf::DtKynapseLinesModel::update ( )

virtual

Update the lines according to the current state of the shared memory buffer.

Only update buffers which are present in internal buffer map.

Reimplemented in DtBhaveLinesModel.

virtual void makVrf::DtKynapseLinesModel::updateAll ( )

virtual

Update the lines according to the current state of the shared memory buffer.

Update all buffers, adding them all the internal buffer map

virtual BufferVector makVrf::DtKynapseLinesModel::bufferNames ( )

virtual

Information about current buffers.

virtual void makVrf::DtKynapseLinesModel::drawBufferWithName ( std::string  tag, bool  draw  )

virtual

Set whether a given buffer is drawn.

virtual void makVrf::DtKynapseLinesModel::transformToLocal ( DtVector &  )

virtual

Transform vector in local coordinates according to useLocalCoord init parameter.

virtual osg::Group* makVrf::DtKynapseLinesModel::parentNode ( )

virtual

Group node representing the parent of the entire lines model geometry.

virtual double makVrf::DtKynapseLinesModel::distanceThresholdSquared ( )

virtual

Regional node lookup distance threshold squared.

DtDebugDrawerSharedMemoryManager& makVrf::DtKynapseLinesModel::memory

(

)
