Visualize Octree.

[Haider-BA]

How to visualize Octree in Tecplot or Paraview or VisIt? If want to couple with some CFD code, is it possible?

Are you wanting to do something like the above, where each 'cube' in the octree is drawn separately?

[Haider-BA]

Yes, something like the video, and want to implement this method: Grid refinement in lattice Boltzmann methods based on volumetric formulation both in 2D(Quadtree) and 3D (Octree). Is it possible to specialize it for quadtree also?
