Visualisation

Run  http://www.paraview.org ParaView software. Open downloaded *.wrl and *.vtk files. Click the Apply button (in the tab Properties). Loaded models.

In the tab Properties set Styling: Opacity to 0.1 for scene_grey.wrl model. For every scene_SSp_bfd*.wrl model set Styling: Opacity to 0.3, then change Coloring from VRMLColor to Solid Color. Click Coloring: Edit and select color to:

• Red = 250, Green: 245, Blue: 255 for scene_SSp_bfd1.wrl,
• Red = 153, Green: 163, Blue: 255 for scene_SSp_bfd2Slash3.wrl,
• Red = 74, Green: 77, Blue: 128 for scene_SSp_bfd4.wrl,
• Red = 171, Green: 177, Blue: 255 for scene_SSp_bfd5.wrl,
• Red = 145, Green: 149, Blue: 213 for scene_SSp_bfd6a.wrl,
• Red = 177, Green: 170, Blue: 255 for scene_SSp_bfd6b.wrl.
