Dream3d data into python

[Charles Xu]

Hi, I'm trying to import and view dream3d data in python in order to transform some of the data so it can be applied elsewhere but I'm not quite sure how to get it to work. I'm using h5py to try and import and access the data but I'm not sure how to access the deeper layers within the dream3d data.

Thanks,

Charles

This might help with reading the euler angles, neighbor list, number of neighbors and grain information for the RVE
hex2p=h5py.File('filename.dream3d','r')

neighborlist=np.array(hex2p['DataContainers']['SyntheticVolumeDataContainer']['Grain Data']['NeighborList'])
featureid=np.array(hex2p['DataContainers']['SyntheticVolumeDataContainer']['CellData']['FeatureIds']).squeeze()
eulerangles=np.array(hex2p['DataContainers']['SyntheticVolumeDataContainer']['CellData']['EulerAngles'])
numneighbors=np.array(hex2p['DataContainers']['SyntheticVolumeDataContainer']['Grain Data']['NumNeighbors'])
