3D EBSD Features

[ralfHielscher]

Implement full 3d support for MTEX

Important

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

current use of MatGeom

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

rewrite `grain3d/slice'

• [x] consider only intersected grains
• [x] compute edges -> tripleJunctions, incidence matrix
• [x] compute all intersections between edges and the plane -> vertices
• [x] compute pairs of neighboring edges
• [x] connect to polygons
• [x] associate the right grain id
• [x] 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

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