The weighting model specifies how mark data are mapped to a weight per point/ion. For atom probe microscopy (APM) mark data are e.g. which iontype an ion has. As an example, different models are used which account differently for the multiplicity of a point/ion during delocalization:

  • unity, all points/ions get the same weight 1.

Weighting factor, in atom probe, often termed multiplicity. The weighting factor is the multiplier with which the integrated intensity contribution from the point/ion gets multiplied. The delocalization computes the integrated intensity for each grid cell.

For atom probe weights are positive and integer specifically the multiplicity of the ion, in accordance with the respective rulesets as defined by weighting_model.

In the case of elements this hashing rule has the advantage that for elements the proton number is their hash value because N is zero.

Users are encouraged to reduce the vertices to unique set of positions and vertices as this supports a more efficient storage of the geometry data. It is also possible though to store the vertex positions naively in which case vertices_are_unique is likely False. Naively here means that one for example stores each vertex of a triangle mesh even though many vertices are shared between triangles and thus the positions of these vertices do not have to be duplicated.

Therefore, summating over the number_of_vertices, allows to extract the vertex identifiers for the i-th face on the following index interval of the faces array: [$sum_i = 0}^{i = n-1}$, $sum_{i=0}^{i = n}$].

Iso-surfaces of arbitrary scalar three-dimensional fields ...

Iso-surfaces of arbitrary scalar three-dimensional fields can show a complicated topology. Paraprobe-nanochem can run a DBScan-like clustering algorithm which performs a connectivity analysis on the triangle soup. This yields a set of connected features with their surfaces discretized by triangles. Currently, the tool distinguishes at most three types of features:

  1. So-called objects, i.e. necessarily watertight features represented polyhedra.

  2. So-called proxies, i.e. features that were replaced by a proxy mesh and made watertight.

  3. Remaining triangle surface meshes of arbitrary shape and cardinality.

These features can be interpreted as microstructural features. Some of them may be precipitates, some of them may be poles, some of them may be segments of dislocation lines or other crystal defects which are decorated (or not) with solutes.
