  1. “Contrast Displays: An Interactive Haptic and Visual Interface for Mesh Quality Analysis” Lisa Durbeck, M.S. C.S.Thesis

  2. Reproduced with permission from http://www.scs.leeds.ac.uk/cpde/knock.html

  3. 3D unstructured tetrahedral mesh

  4. Approach: • reduce mesh to a handful of elements • interaction model is compare/contrast • compare geometry, compare error level • visual comparison info: color, shape • haptic comparison info: texture • provide analytic information in a Closeup view • what matters: size, shape, orientation of tet. and its neighbors

  5. colors 0.02 - 0.03 0.01 - 0.019 0.0 - 1e-6

  6. geometrical considerations: shape, size, location, face orientation

  7. force feedback 0.16 force -0.16 Distance: 0 to 6 cycles/mm

  8. comparative information

  9. Software System Development
