makVrv::DtWeatherLayerGroup Class Reference

A group node which serves as a root for weather layers.

This group node is the top level node in the scenegraph for weather layers. The node also serves as the main interface to create and modify weather layers. There is 1 geode under this node for drawing weather layer effects.

This class hooks into the simulation update which updates all active weather layer effects. Weather layer effects queue update jobs which are updated in parallel using a job splitter. There is also a post update for each weather layer for items that cannot use multithreading (currently intersection tests).

During scenegraph culling, this class calls cull methods on individual weather layers. If a weather layer effect is not culled, it submits a sort job to a job splitter and finally the queued sorting jobs are ran in parallel.

virtual void makVrv::DtWeatherLayerGroup::registerLayer ( DtWeatherLayer *  layer, bool  global = false  )

virtual

Registers the layer for use with this group. unregisterLayer should be called by the layer owner when it no longer in use. This group does not own the layer obect. Set global to true if the layer does not belong to a local area.

Parameters

layer	The layer to register.
global	True if the layer is a used as a global effect.

virtual void makVrv::DtWeatherLayerGroup::unregisterLayer ( DtWeatherLayer *  layer )

virtual

Unregisters a previously registered layer from this group. This group does not own the layer obect.

Parameters

layer

The layer to unregister.

virtual void makVrv::DtWeatherLayerGroup::setGlobalWind ( float  windDirectionRad, float  windSpeedMps  )

virtual

Sets the current global wind to use for weather layers.

Parameters

windDirectionRad	The wind direction in radians.
windSpeedMps	The wind speed in meters per second.

virtual void makVrv::DtWeatherLayerGroup::drawWeatherEffects ( DtWeatherEffect::DrawData &  drawData )

virtual

Draw all weather effects.

virtual float makVrv::DtWeatherLayerGroup::timeStep ( ) const

virtual

Returns the last simulation timestep.

virtual void makVrv::DtWeatherLayerGroup::registerWeatherEffectsObject ( DtOsgWeatherEffectsObject *  weatherEffectsObject )

virtual

called by the DtOsgWeatherEffectsObject constructor to register itself when it is created.

void makVrv::DtWeatherLayerGroup::connectSignals ( )

protectedvirtual

Signal to handle when the ground snow accumulation changes.

virtual void makVrv::DtWeatherLayerGroup::slot_simulationUpdate ( )

protectedvirtual

Signal handler to run a simulation update.
