makVrv::DtShaderEffectRain Class Reference

DtShaderEffectRain injects custom shaders into the scene, Handles rain on the ground causing the ground to look damp. Also adds an effect to puddled areas which show rain drops in the puddles.

virtual void makVrv::DtShaderEffectRain::initializeEffect ( const std::vector< osg::StateSet * > &  stateSets )

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

Reimplemented from makVrv::DtShaderEffect.

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

virtual

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

Implements makVrv::DtShaderEffect.

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

overridevirtual

handle destruction of graphics objects when the context is destroyed

Reimplemented from makVrv::DtShaderEffect.

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

Implements makVrv::DtShaderEffect.

virtual void makVrv::DtShaderEffectRain::setCameraLocation ( const DtVector &  location )

virtual

sets the location for localized effects.

Reimplemented from makVrv::DtShaderEffect.

virtual const DtVector& makVrv::DtShaderEffectRain::cameraLocation ( ) const

virtual

virtual int makVrv::DtShaderEffectRain::rainEffectTextureSize ( void  ) const
