Hello all,

I'am doing CFD on an adaptive Octree grid and i would like to visualise my results using Paraview. However, the structure of the octree grid is not inherited when i load my data from a .csv format (list of x,y,z, fieldvalue). Now i do the folowing:
i load my data as points (table to points) and next create a Delauny triangularization.

With that i can see my results nicely, but for adaptive grids the triangulation is quite costly every timestep, and i can imagine that if paraview knows the data is in an octree structure it might be more effective. Furthermore, the documentation notes that octrees are a recognized data structure. But i cannot find how to use this feature.

Can somebody give me some pointers on how to get 3d octreedata in paraview?
Do i need to export my data in an octree-specific way?
