Data Structures and Workflows for ICME

major components of the interface labeled. In this rendering, the pipeline issues and output are

capabilities. When exporting a SIMPL data file, the user may elect to write a
companion XDMF file, which is essentially an XML document that explains how
the data are organized in the HDF5 file [59]. ParaView has facilities to import this
XDMF file, allowing for efficient volumetric visualization of the data processed by
SIMPL.
5.4 DREAM.3D: An ICME Workflow Tool
DREAM.3D is essentially a set of SIMPL plugins customized to process materials
data. As such, it inherits all the benefits of the SIMPL data structure described above.
DREAM.3D contains a number of capabilities, including:
• Import and export of a variety of file formats, including many image formats,
FEM file formats, generic ASCII and binary files, HDF5 files, and the SIMPL
file format
• Feature identification approaches, such as expectation maximization, connected
components segmentation including metrics such as misorientation, and clustering approaches
• Texture analysis, including pole figure plotting, orientation distribution function
sampling, disorientation and average orientation computations, and fundamental
zone reductions
• Reconstruction of 3D data from 2D slices, for both images and crystallographic
EBSD measurements
