Surface3D - glossy vs matte

  • Qt Data Visualization Surface3D seems to have a default "glossy" look to it. Is there some way to vary that, e.g. to give it a duller "matte" look? I don't see a property to do that...


  • I'm displaying a terrain based on actual topographic data, and the qt datavisualization surface actually looks like smooth shiny plastic. The Theme3D has ambientLightStrength and lightStrength (specular light source) properties. I experimented with those. Turning down lightStrength diminishes highlights but also fades the shadows - so below a certain level the highlights are nearly gone but topography is nearly invisible. Is there no way to turn down those specular highlights while preserving shadows?
