Martin Diehl a4bbdd5ecb further commenting, removing not used variables and code (marc2vtk) 2016-03-04 19:06:36 +01:00
Martin Diehl bbb00b30e8 using numpy random 2015-12-17 21:26:59 +00:00
Philip Eisenlohr 30a481f152 fixed forgotten symmetry property for average orientation. 2015-11-14 04:36:46 +00:00
Philip Eisenlohr 6211a9faad symQuats-related functions can take optional argument to downselect return values. 
“getAverageOrientations” —> “average” and takes optional multiplicities of orientations in list.

Martin Diehl b700721905 comment on literature 2015-11-08 11:44:46 +00:00
Aritra Chakraborty 9ea0898cd9 corrected the convention added yesterday; “proper” and ‘improper” was the wrong way around. “proper = True ” considers the bigger (2 adjacent) SST. In general, an improper rotation is implicitly assumed when projecting a pole into the (single) SST, hence this is termed “improper” now. 2015-10-23 20:16:01 +00:00
Philip Eisenlohr 15963391aa inSST and inversePole now can consider the secondary SST related to improper rotations. Secondary SST is immediately neighboring (positively rotated around Z). 2015-10-22 21:15:15 +00:00
Philip Eisenlohr 7df8d95cd0 slightly cleaner way of dealing with disorientation calculation when axis not required to fall into SST. 2015-10-09 13:03:10 +00:00
Martin Diehl 4c46d155ec line continuation not needed 2015-10-09 10:24:17 +00:00
Harsha Phukan 24bd3a6eee added “non-strict” version to find disorientation, neglecting the search for axis falling into SST (has linear instead of quadratic effort). 2015-09-16 17:07:02 +00:00
Philip Eisenlohr 31bb27268c removed dangerous property overload (.asQuaternion() —> .quaternion) 2015-09-09 22:37:18 +00:00
Tias Maiti eb5ad7528f fixed bug in asEulers() output in degrees 2015-08-29 23:22:32 +00:00
Philip Eisenlohr 636eb8a087 multiple fixes and improvements. 
1) asAngleAxis got “degrees” switch, fixed buggy output for negative angles, now angles are always non-negative.
2) removed rotateBys.
3) asEulers corrected for cases w==z or x==y.
4) added method symmetryQuats.
5) calculation of disorientation (finally) fixed, returns tuple (disorientation quaternion, index symA, index symB, boolean whether A—>B or B—>A).
