Visualization Process

• Data Geometry

• The most important step

• The most difficult, creative, and artistic step

• Some data suggest natural translations:

  • Data which is geometry (e.g. terrain)
  • Scalar data (e.g. atmospheric pressure)
  • Vector data in 2D (e.g. 2D fluid flow)

• Some methods of converting data to geometry

  • Slices (2D cross sections)
  • Isosurface (3D contours)
  • Volume rendering (direct viewing)
  • Streamlines (vector flow)
