Martin Diehl 37de73535d following PEP style guide 2019-05-30 20:08:39 +02:00
Philip Eisenlohr 4c7af713f1 added explicit method Rotation.fromBasis, which can treat real and reciprocal basis sets 2019-05-14 12:59:21 -04:00

Martin Diehl b97f10b6ff forgotten changes in last commit + fromRandom 2019-04-19 08:17:02 +02:00
Martin Diehl feca9fe0a0 Again changes to the return values. 
A python function with no return value returns 'None'
 2019-04-19 08:04:04 +02:00
Martin Diehl 9a43c2e4c5 fixed return values 
- homomorph, standardize, etc. are silent in-place operations (return
None)
- homomorphed, standardized, etc. are out-of place operations that
report
 2019-04-19 01:05:48 +02:00
Philip Eisenlohr 4183eeaeca [skip ci] disorientation may return full-fledged orientation obj and aux info, added rotation.standardize(d) 2019-04-18 18:06:00 -04:00
Martin Diehl c4f56703a4 proper definition of homomorph 2019-04-18 17:11:51 +02:00
Martin Diehl 7570b187e7 do explicit homomorphing 
only in cases when the underlying math cannot guarantee that the
resulting quaternion follows the convention
 2019-04-18 16:26:05 +02:00
Martin Diehl e8464814ae explicit is better than implicit 
- if the quaternion does not follow the convention, use
"fromQuaternion(acceptHomomorph=True)"
 2019-04-18 14:46:12 +02:00
Martin Diehl 71b0036323 return rotation as misorientation 2019-04-18 14:26:53 +02:00
Martin Diehl 481aac7952 misorientation calculation did not always follow convention 
- return homomorphed quaternion to ensure that real component is > 0
(equivalent to have axis angle limited to [0, pi]

Martin Diehl 48b0307fab using new rotation class 
cannot rotate matrices (3,3) and (3,3,3,3) at the moment
 2019-02-12 00:27:13 +01:00
Martin Diehl 7ee933b79d Rotation class 
uses (and hides) Quaternion2. Should replace Quaternion class.
Orientation class should inherit from Rotation and adds symmetry.

Martin Diehl e931b716fd conversion routines from Marc de Graefs 3D rotation repository 
Python version available on https://github.com/MarDiehl/3Drotations
 2019-02-11 23:15:19 +01:00
Martin Diehl 40740b831e reverted code removal 
was not "just commented out" but served as documentation. now easier to
see

Martin Diehl 878331e5e9 this code was never used and is quite old 2019-02-01 19:29:19 +01:00
Philip Eisenlohr e6fe312f85 Corrected documented value for P (= -1!). Instead of repeating the assignment P=-1 in multiple internal functions, it might be advisable to define a class-wide parameter? 2019-02-01 14:04:55 +01:00
