makVrv::DtHbaoDrawable Class Reference

class used to render HBAO during the post processor camera draw. Uses the NVIDIA GFSDK HBAO library to generate a texture which we then apply to the scene using a post processor rendering pass.

virtual

destructor

makVrv::DtHbaoDrawable::DtHbaoDrawable ( )

delete

not allowed - default constructor

makVrv::DtHbaoDrawable::DtHbaoDrawable ( const DtHbaoDrawable &  )

delete

not allowed - copy constructor

makVrv::DtHbaoDrawable::DtHbaoDrawable ( DtDe &  de )

protected

constructor. private. only creator can create

Member Function Documentation

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

delete

not allowed - equals operator

virtual void makVrv::DtHbaoDrawable::drawImplementation ( osg::RenderInfo &  renderInfo ) const

overridevirtual

Override the draw implementation to run the hbao texture generation and post processor.

virtual void makVrv::DtHbaoDrawable::reloadShaders ( )

virtual

Reload the HBAO shader program.

virtual void makVrv::DtHbaoDrawable::setDepthTexture ( osg::Texture *  texture )

virtual

overridden currently unneeded because the postprocessor drawable is always deleted/recreated because of channel creation/destruction virtual void releaseGLObjects(osg::State* state = 0) const;

set the depth texture

virtual void makVrv::DtHbaoDrawable::setBaseTexture ( osg::Texture *  texture )

virtual

set the base texture which is used as input to the HBAO effect generation

virtual void makVrv::DtHbaoDrawable::setOcclusionTexture ( osg::Texture *  inputTex )

virtual

set the occlusion texture from the osgChannel

virtual void makVrv::DtHbaoDrawable::setViewSize ( int  width, int  height  )

virtual

set the viewport size

virtual void makVrv::DtHbaoDrawable::createProgramIfNecessary ( void  ) const

protectedvirtual

create the program if needed

virtual void makVrv::DtHbaoDrawable::cleanupGpuMemory ( void  )

protectedvirtual

cleanup the memory allocated on the GPU

virtual void makVrv::DtHbaoDrawable::releaseHbaoRenderTexture ( )

protectedvirtual

releases the HBAO render to textue and associated fbo

void makVrv::DtHbaoDrawable::updateHbaoSettings ( ) const

protected

not virtual since it is called by the constructor. Used to syncronize the hbao settings with the shared state. Don't think of this as really const since it modifies a mutable paratemers. All required due to osg requirement that draw implementation is const.

void makVrv::DtHbaoDrawable::createTextureViewsIfNecessary ( osg::State *  state ) const

protected

brief create new texture views into the multiview arrays if nessacary
