virtual void makVrv::DtShaderEffect::initializeEffect ( const std::vector< osg::StateSet * > &  statesets, DtIndirectTextureProcessor *  textureProcessor, DtOsgRenderer &  osgRenderer  )

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 in makVrv::DtShaderEffectSnow, and makVrv::DtShaderEffectRain.

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

pure virtual

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

Implemented in makVrv::DtShaderEffectSnow, and makVrv::DtShaderEffectRain.

virtual void makVrv::DtShaderEffect::updateTextureUniforms ( unsigned int  contextId )

virtual

update the texture uniforms for this shader effect

virtual void makVrv::DtShaderEffect::setEffectDirty ( bool  dirty )

virtual

set this effect dirty so that it will be reinitialized before the next time it is run

virtual bool makVrv::DtShaderEffect::effectDirty ( )

virtual

get if this effect is dirty

virtual void makVrv::DtShaderEffect::updateImGui ( )

pure virtual

update the imgui widgets and readback any changes from them

Implemented in makVrv::DtShaderEffectSnow, and makVrv::DtShaderEffectRain.

virtual void makVrv::DtShaderEffect::updateUniforms ( )

pure virtual

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

pure virtual

release the gl objects for this class

Implemented in makVrv::DtShaderEffectSnow, and makVrv::DtShaderEffectRain.

virtual int makVrv::DtShaderEffect::loadShaderEffectTexture ( const std::string &  filename, const std::string &  uniformName  )

protectedvirtual
