sigma sections for ODF and orientation plotting
The MTEX default for plotting an ODF. Sigma sections are the pole figure of the c* axis, split up by sigma = phi1 - phi2. Unlike Euler angle sections they distort orientation space only mildly, so a component keeps its shape across the sections.
Syntax
oS = sigmaSections(cs1,cs2)
oS = sigmaSections(cs1,cs2,'sections',5)
oS = sigmaSections(cs1,cs2,'sigma',(0:15:90)*degree)Input
| cs1, cs2 | crystalSymmetry, specimenSymmetry |
Options
| sections | number of sections |
| sigma | explicit section values |
Class Properties
| omega | the sigma value of each section |
| h1, h2 | the Miller the sections are built from |
| sR | sphericalRegion each section is plotted on |
| referenceField | S2VectorField sigma is measured against |
Example
mtexdata dubna
odf = calcODF(pf,'silent');
plotSection(odf,sigmaSections(odf.CS,odf.SS))pf = PoleFigure (y↓→x)
