Assignment Operator Not implemented – Assignment Not Allowed.

virtual void makVrv::DtVariableRateShadingImageUpdater::drawImplementation ( osg::RenderInfo &  info ) const

virtual

draw the vrs image update pass

virtual void makVrv::DtVariableRateShadingImageUpdater::releaseGLObjects ( osg::State *  state ) const

virtual

frees resources on context release

virtual void makVrv::DtVariableRateShadingImageUpdater::shouldUpdate ( bool  shouldUpdate )

virtual

flags if the vrs image should be updated

virtual void makVrv::DtVariableRateShadingImageUpdater::restoreLastFboTarget ( GLenum  fboTarget )

virtual

/brief set the fb rebind target type for resetting the last applied fbo (0 to not rebind)

virtual void makVrv::DtVariableRateShadingImageUpdater::update ( osg::State *  state ) const

protectedvirtual

pre draw callback so concrete implementations can update uniforms etc at this point the shader will be bound

Reimplemented in makVrv::DtVrsGazeMapUpdater.

virtual void makVrv::DtVariableRateShadingImageUpdater::initProgram ( osg::State *  state ) const

protectedvirtual

called by draw if program is null so concrete implementation can create program

Reimplemented in makVrv::DtVrsGazeMapUpdater.
