C++ (Cpp) RenderSymbol Examples

Example #1

File: osgearth_featureeditor.cpp Project: DavidLeehome/osgearth

Style buildStyle( const osg::Vec4 &color, float width )
{
    // Define a style for the feature data. Since we are going to render the
    // vectors as lines, configure the line symbolizer:
    Style style;

    LineSymbol* ls = style.getOrCreateSymbol<LineSymbol>();
    ls->stroke()->color() = color;
    ls->stroke()->width() = width;    
    ls->tessellation() = 10;

    AltitudeSymbol* as = style.getOrCreate<AltitudeSymbol>();
    as->clamping() = AltitudeSymbol::CLAMP_TO_TERRAIN;
    as->technique() = AltitudeSymbol::TECHNIQUE_SCENE;

    RenderSymbol* rs = style.getOrCreateSymbol<RenderSymbol>();
    rs->depthOffset()->enabled() = true;
    rs->depthOffset()->minBias() = 1000;

    return style;    
}
