3D EBSD Features

[ralfHielscher]

Implement full 3d support for MTEX

Important

• compute normal directions when importing dream3d grains
• remove dependency from matgeom
• revisit grain3d/slice

current use of MatGeom

• grain3d.isIntersected replace isBelowPlane by plane3d/dist
• grain3d/triangulate -> two possible implementations / take smallest angle first
• grain3Boundary/surface should take the code from grain2d/area

rewrite `grain3d/slice'

• consider only intersected grains
• compute edges -> tripleJunctions, incidence matrix
• compute all intersections between edges and the plane -> vertices
• compute pairs of neighboring edges
• connect to polygons
• associate the right grain id
• consider the case of not connected grains

the following functions needs to be ported

pseudo3d EBSD

• calcTraces
• cat should return EBSD3 if pixels are not within a single plane
• ebsdSquare and EBSDHex should return gradientZ
• curvature should make use of gradientZ
• fill
• fillByGrainId
• findByLocation
• gridify should work also for maps in the xz and yz plane
• inpolygon
• interp
• reduce
• selectInteractive
• smooth
• spatialProfile
• calcUnitCell
• weightedBurgersVector

pseudo3d in grain2d

• checkInside
• inpolygon

EBSD3

• calcGrains
• calcTraces
• fill
• fillByGrainId
• findByLocation
• gridify
• interp
• KAM
• plot
• plotUnitCells
• reduce
• smooth
• slice
• weightedBurgersVec

*EBSDcube

grain3d

• grain3Boundary/misorientation, grain3Boundary/ebsdId
• docu
• grain3dboundary plot (allow rgb, scalar value )
• sample data set that can be loaded with mtexdata
• boundary normal distribution
• grain3d/slice - plane through 3 points
• neper returns grain3d
• select grain by mouse in 3d
• fitEllipse
• indexing should be possible with "phaseName"
• grain3d/surface
• grain3Boundary/curvature
• grain3/hasHole
• grain3/isConvex
• grain3/convHull
• rotate grain3, grain3boundary
• intersection should not change the id
• grain3/intersect
• grain3/checkInside
• grain3/neighbours, numNeighbours
• simulateGrains should set correct symmetry
