NXisocontour¶
Status:
base class, extends NXobject
Description:
Computational geometry description of isocontouring/phase-fields in Euclidean space.
Iso-contouring algorithms such as MarchingCubes and others are frequently used to segment d-dimensional regions into regions where intensities are lower or higher than a threshold value, the so-called isovalue.
Frequently in computational materials science phase-field methods are used which generate data on discretized grids. Isocontour algorithms are often used in such context to pinpoint the locations of microstructural features from this implicit phase-field-variable-based description.
One of the key intentions of this base class is to provide a starting point for scientists from the phase-field community (condensed matter physicists, and materials engineers) to incentivize that also phase-field simulation data could be described with NeXus, provided base classes such as the this one get further extend according to the liking of the phase-field community.
Symbols:
The symbols used in the schema to specify e.g. dimensions of arrays.
d: The dimensionality of the description.
