makVrv::DtShaderEffectManager Class Reference

DtShaderEffectManager injects custom shaders into the scenes, uses DtShaderEffect objects to add rendering effects to the ground. Currently has effects for rain and snow but more could be added for ice, sand, etc...

Member Function Documentation

DtShaderEffectManager& makVrv::DtShaderEffectManager::operator= ( const DtShaderEffectManager &  )

delete

Assignment Operator not implemented – Copy not allowed.

virtual void makVrv::DtShaderEffectManager::initializeEffects ( )

virtual

initializes or reinitializes the effects. Called by DtOsgRenderer at startup and whenever reload shaders is triggered reloads the shader changes if triggered from reload shaders but the texture is not reloaded off disk due to osgFileCache

virtual void makVrv::DtShaderEffectManager::updateTextureUniforms ( )

virtual

called by the arena per frame, per context to check if the texture has been assigned an address.

virtual void makVrv::DtShaderEffectManager::update ( )

virtual

called by DtOsgRenderer::update(), updates the per frame uniforms for the shader effects and sets up IMGui

virtual void makVrv::DtShaderEffectManager::updateChannel ( DtOsgChannel *  channel, osg::Vec3d  pos  )

virtual

called by DtOsgChannel::update(), updates the per channel uniforms

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

virtual

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

virtual void makVrv::DtShaderEffectManager::slot_reloadShader ( )

virtual

called when the signal_reloadShader is triggered. Marks the effect dirty so it can be recreated

virtual void makVrv::DtShaderEffectManager::slot_windSpeedChanged ( float  metersPerSecond )

virtual

handle a wind speed changed signal

virtual void makVrv::DtShaderEffectManager::slot_windDirectionChanged ( float  radians )

virtual

handle a wind direction changed signal

virtual DtOsgWeatherEffectsObject* makVrv::DtShaderEffectManager::findWeatherEffectsObject ( )

virtual

Use to get the local settings for the weather effects. Currently only has snow parameters in it.

virtual const DtOsgWeatherEffectsObject* makVrv::DtShaderEffectManager::findWeatherEffectsObject ( ) const

virtual

Use to get the local settings for the weather effects. Currently only has snow parameters in it.

virtual void makVrv::DtShaderEffectManager::releaseGLObjects ( osg::State *  state )

virtual

release the gl objects for this class

virtual bool makVrv::DtShaderEffectManager::anyEffectDirty ( osg::Camera *  camera )

virtual

are there any dirty effects for pass camera

virtual void makVrv::DtShaderEffectManager::installEffectsToCamera ( osg::Camera *  camera )

virtual

This is called to install shader effects to the given camera. Each shader effect will be initialized if enabled. Shader effects will generally modify the camera state set by adding virtual programs and required shader uniforms. This method is called explicitly by DtOsgChannel for the RTT camera.

static DtShaderEffectManager& makVrv::DtShaderEffectManager::instance ( DtDe &  de )

static

Get/create instance of sky object manager.

static const std::string& makVrv::DtShaderEffectManager::theClassName ( )

static

Get the name this class is registered by.

virtual void makVrv::DtShaderEffectManager::updateImGui ( )

protectedvirtual

update the imgui widgets and readback any changes from them

virtual void makVrv::DtShaderEffectManager::updateUniforms ( )

protectedvirtual

update the uniforms that may need to be changed based on the imgui or regular gui inputs.

virtual DtShaderEffectPerChannelData& makVrv::DtShaderEffectManager::getOrCreatePerChannelData ( osg::Camera *  camera, bool  createShaderEffects  )

protectedvirtual

gets or creates the data associated with a channel camera

Parameters

camera	The camera to create the data for
createShaderEffects	Shaders effects are created for the camera if true

virtual void makVrv::DtShaderEffectManager::flushInvalidChannels ( )

protectedvirtual

check if the channel still is valid. If not then destroy the corrisponding shader effects

virtual void makVrv::DtShaderEffectManager::initializeChannelEffects ( )

protectedvirtual

Check if any of the effects are enabled and if they are dirty, then applies the effects to all known channel camera statesets.

virtual DtTextureAddressOp* makVrv::DtShaderEffectManager::createTextureAddressOp ( )

protectedvirtual
