Example #1

File: ContourMap.cpp Project: 2php/osgearth

void
ContourMap::onUninstall(TerrainEngineNode* engine)
{
    if ( engine )
    {
        osg::StateSet* stateset = engine->getStateSet();
        if ( stateset )
        {

            stateset->removeUniform( _xferSampler.get() );
            stateset->removeUniform( _opacityUniform.get() );

            stateset->removeTextureAttribute( _unit, osg::StateAttribute::TEXTURE );

            VirtualProgram* vp = VirtualProgram::get(stateset);
            if ( vp )
            {
                Shaders pkg;
                pkg.unload(vp, pkg.ContourMap_Vertex);
                pkg.unload(vp, pkg.ContourMap_Fragment);
            }
        }

        if ( _unit >= 0 )
        {
            engine->getResources()->releaseTextureImageUnit( _unit );
            _unit = -1;
        }
    }
}

Example #2

File: Fog.cpp Project: 2php/osgearth

void FogEffect::detach( osg::StateSet* stateSet )
{
    VirtualProgram* vp = VirtualProgram::get(stateSet);
    if ( vp )
    {
        Shaders pkg;
        pkg.unload( vp, pkg.Fog_Vertex );
        pkg.unload( vp, pkg.Fog_Fragment );
    }
}

Example #3

void
GeodeticGraticule::removeEffect()
{
    if (_mapNode.valid() == false)
        return;

    osg::StateSet* stateset = _mapNode->getTerrainEngine()->getSurfaceStateSet();

        if ( vp )
        {
            Shaders package;
            package.unload( vp, package.Graticule_Vertex );
            package.unload( vp, package.Graticule_Fragment );

            stateset->removeUniform( COLOR_UNIFORM );
            stateset->removeUniform( WIDTH_UNIFORM );
        }
    }
}

Example #4

            Shaders pkg;
            pkg.unload( vp, pkg.AlphaEffectFragment );
        }
