Roadmap
Assigned to Next Minor Release
Kernel Density Estimation
Improve automatic optimal kernel detection from EBSD data
Planned for Next Minor Release
Grain Boundary Analysis (Florian Bachmann)
- Compute grain boundary planes.
- Analyze and visualize the distribution of grain boundary planes.
- Classify twist / tild grain boundaries.
Plotting: support datacursor for spherical projections, (pole figures, inverse pole figure, odf plots) to get coordinate (and function value)
Assigned to Next Major Release
Robust Mean Computation
Find and implement an algorithm that finds under certain conditions the true mean orientation for a given set of orientations!
Bingham Distribution
compute Fouriercoefficients of Bingham ODFs.
Future
EBSD Statistics
Implement results of K. G. v.d. Boogaart dissertation. i.e. allow MTEX to answer the following questions:
- is a EBSD data set a random sample of a certain ODF
- are two EBSD data sets random sample of the same ODF
Misorientation Analysis
Allow to compute an misorientation ODF from EBSD data. Therefore, a new class MODF is needed which differs from an ordinary ODF by the fact that the specimen symmetry is replaced by the crystal symmetry of the second phase.
This requires a better find functionality in SO3Grid
- allow volume computation for miss axes
- allow annotations in misaxes plot
ODF Analysis
Provide a function that is able to approximate an ODF by a small number of simple components, i.e. unimodal components and fibres.
Joined Counts
Incorporate the results of M�ller.
Grain Simulation
Allow to simulate grains under certain assumptions. To be used for joined counts statistics and ODF -> MODF analysis.
Voronoi Decomposition of the Orientation Space
Use the Rodriguez representation to compute an Voronoi neighborhood graph of a set of orientations. This can be used for faster searching in SO3Grids and for the decomposition of ODFs into components.
New Class Fibre
Implement a new class fibre, which can be used for any computations involving fibres.
Minor Improvements
- EBSD colorcoding
- fix crystal coordinate system for symmetry 2/m
- improve template files
- say explicetly in generic wizard which columns has to be specified
- implement grain/rotate, grain/flipud, grain/fliplr
- better ODF import / export
- add kernel names by Matthies
Supported/Implemented since MTEX 3.3
Single Grain Analysis
- Detect polar, oblate and spherical grains.
- Profiles thourgh grains
Topological Grain Data Structure (Florian Bachmann)
The function segment2d should provide a grain class that allows to answer questions like:
- give me all phase one to phase two grain boundaries
- give me all grain boundaries between grains with a certain missorientation
Therefore not only the neigbouring grains has to be stored in the grain object but also the line segment representing the grain boundary.
Supported/Implemented since MTEX 3.1
Computation of Material Properties
Compute various macroscopic material properties for EBSD data and ODFs.
Supported/Implemented since MTEX 3.*
Bingham Distribution
Implement Bingham parameter estimation from EBSD data
