Angio-VR vs. Angio-IsoSurface

Iso surface is the set of points ot the data set that have the same iso value.
The point set forms a closed surface, which can be extracted and represented by a triangle mesh.

Advantages:

  • Occlusion of hidden surfaces.
  • Triangle mesh can be shaded.

Disadvantages:

  • Not the entire data visible, only parts with a respective iso value.
  • Mesh extraction is not interactive.
