the grains of a volume as closed polyhedra, given by the incidence I_GF of grains and the faces of a grain3Boundary: what calcGrains returns for a volume, the counterpart of grain2d

Syntax

grains = calcGrains(ebsd3)
grain3d.fromFaces(V, F, I_GF, ori, CSList, phaseId)
grain3d.load('grains.dream3d')

Input

`id`	persistent grain ids
`phaseId`	phase-list index of every grain
`CSList`	phaseList or list of crystal frames
`numPixel`	voxel count of every grain
`meanRotation`	rotation representing each grain mean
`GOS`	grain orientation spread in radians
`I_GF`	sparse signed grain-by-face incidence matrix
`boundary`	grain3Boundary mesh shared by the grains
`frame`	specimen reference frame
`prop`	optional dictionary of per-grain properties
`phaseMap`	optional mapping from phase-list entries to original file phase numbers

Properties

`id`	grain ids, which need not equal positions in a selected list
`phaseId`	phase-list index of each grain
`numPixel`	number of voxels assigned to each grain
`meanOrientation`	mean orientations for grains of one phase
`GOS`	grain orientation spread in radians
`boundary`	grain3Boundary mesh separating the grains
`I_GF`	sparse signed incidence matrix, grain rows by boundary-face columns
`volume`	enclosed volume of each grain in cubed spatial units
`surfaceArea`	surface area of each grain in squared spatial units
`frame`	specimenFrame of the geometry

Signature

grain3d(id, phaseId, CSList, numPixel, meanRotation, GOS, I_GF, boundary, frame, prop=None, phaseMap=None)
