grain reconstruction from 3d EBSD data on a voxel grid

Description

Voxels are 6-connected. A boundary face separates two neighbouring voxels the criterion tells apart; together with the outer hull the faces close every grain, so volumes follow from the divergence theorem. notIndexed voxels form notIndexed grains.

Syntax

[grains, ebsd] = calcGrains(ebsd,'angle',10*degree,'minPixel',5)
lagb = 2*degree;
hagb = 10*degree;
grains = calcGrains(ebsd,'angle',[hagb lagb])

Reconstruction low and high angle grain boundaries.

grains = calcGrains(ebsd,'grainId')

Grains from a grainId stored with the data, e.g. imported from a file.

grains = calcGrains(ebsd,'angle',{angle_1 angle_2 angle_3})

Specify phase dependent thresholds. Thresholds follow the same order as ebsd.CSList and should have the same length.

Input

ebsd EBSD3square

Options

angle misorientation angle that indicates a grain boundary
minPixel minimum number of voxels that form a grain. No indexed grain smaller than this is returned; the voxels of one that would be are marked notIndexed
soft [angle delta] soft threshold instead of a hard one
fmc fast multiscale clustering method
mcl Markovian clustering algorithm

Flags

grainId connect voxels with the same ebsd.grainId instead of a criterion on the orientations

Output

grains grain3d, the boundary consists of triangles, two per voxel face
ebsd EBSD3square with additional property grainId
