Philip Eisenlohr 87767f0cc2 Merge branch 'no-python-quaternion' into 'development' 
No python quaternion

See merge request damask/DAMASK!122
 2020-01-15 22:52:55 +01:00
Martin Diehl 8a674d0279 2 bugfixes: 
- mixed up other and me when removing quaternion class
- 1000 random orientations are enough for testing
 2020-01-14 22:30:08 +01:00
Martin Diehl 9d1c1fdb92 enforce Re(q) > 0 2020-01-14 11:33:18 +01:00
Martin Diehl 3afc011a58 fix for untested functionality 
thanks to prospector
 2020-01-14 10:34:13 +01:00
Martin Diehl 06fc374359 avoid overhead 
length of random quaternion is one, no need to go via fromQuaternion but
direct initialization and standardization suffices
 2020-01-14 10:22:51 +01:00
Martin Diehl 8e5aa60f34 fixed (and polished) printing 2020-01-14 09:37:59 +01:00
Martin Diehl 26c242b997 not needed anymore 
conceptually, having the quaternion class is nice but performance-wise
it is a nightmare and prevents vectorization

Philip Eisenlohr 300f1b7015 added options to return "natural" versions of asQ, asRodrig, and asAxisAngle 2020-01-11 11:36:22 -05:00
Martin Diehl 6a8783bab8 these functions are static 
class methods change are allowed to change the attributes of the class.
This is not what we do here

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)"

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]
