loop and increasing memory usage.
Modifiers should never call mesh_get_derived_final or similar, only
use ob->derivedFinal if it exists, if the dependencies are set correct
and there are no cycles, it will be there.
- pep8 script was giving an error on non utf8 scons source files.
- use PyList_SET_ITEM macro when list type is ensured.
- all mathutils types use subtypes to create new types when available.
- use defines MAT3_UNITY, MAT4_UNITY to initialize unit matrices.
- no rotation resulted in NAN location.
- subtraction of pivot done in wrong order made the constraint give odd results when rotating on more then 1 axis.
- use sizeof() in more places.
- fixed some off by 1 bugs copying strings. setting curve font family for instance was 1 char too short.
- replace strncpy and strcpy with BLI_strncpy
mat4_to_eul & mat3_to_eul are already working this way.
Without this we get problems with constraints, eg:
rotation on the Y axis over 90d can be represented by setting the X and Z to -PI, Y would decrease to 0 (infact 180d).
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.
- some remove() functions took an int argument rather then the item to remove.
- disallow None argument.
- raise an error if the item isnt in the collection.
1) Fixed some weird formatting introduced during math-lib cleanups, and some other inconsistencies
2) Optimised the Maintain Volume constraint by taking the value calculations out
Copy All Constraints Operators:
* Added one for bones too
* These are now included in the menus
* Removed some weird/extra code copying/changing/bleh the actcol/totcol stuff...
This constraint allows an object or bone to have their rotations applied as if their origin/pivot-point was located elsewhere. The most obvious uses include foot-roll, see-saws, but could also include more complicated rolling-box examples.
== Usage Examples ==
=== Foot Roll ===
1. Add 'Pivot' Constraint to the bone without any target.
2. Set the 'Y' value of the offset to the length of the bone. Usually this should be negative (if you rig with feet facing 'forwards' along -Y axis). This gives you a pivot point relative to the bone's (preconstraint) location, which should be at the tip of the bone here. Disabling the 'Use Relative Offset' would make this offset be relative to 0,0,0 instead of to the owner/bone-head.
3. Ensure that the 'Pivot When' setting is set to '-X Rot', (default) which means that the pivot will only used when the rotation on the X-Axis is negative to get tip-toe 'roll'.
=== See Saw ===
1. Add a 'Pivot' constraint too see-saw plank object, this time with a target that you wish to have as the pivot-point. It's possible to do this without too (as before), but is less intuitive.
2. Optionally, if you want the plank slightly raised, set the z-offset value, which should make the pivot-point used to be relative to the target with the z-offset applied.
3. Ensure that 'Pivot When' is set to 'Always', which means that the pivot will always be used, irrespective of the rotation.
== Notes ==
* The 'Pivot When' setting has been integrated in the constraint, since this is something that will often be required for these setups. Having to set up additional drivers to drive the constraint to do this kindof beats the purpose of providing this.
* The 'Offset' functionality is probably not presented as clearly as it could be. We may need to go over this again.
* For foot-roll - if any scaling of the foot is required, simply set up a driver on the y-offset to make this dynamically respond to the "scale" RNA property of the bones (don't use the "Transform Channel" vartype since that won't work correct here). However, this shouldn't be common enough to warrant special treatment.
* Removed some un-needed armature code stubs
* Manually copying over the values of constraints in the constraint copy() callbacks should NOT be needed. Removed this from the Spline IK constraint. The manual process is only a hacky aspect of the modifier stack only!
This commit removes the Old Track method (used to be found under Object -> Animation -> Track), with all existing instances of this being converted to Track To Constraints. In fact, while performing this removal, I found that this was supposed to have happened in version 2.27 already, but for some reason the options were left in, and this function managed to survive for a further decade.
I've left the tracking axes around still, since it seems some curve tools still use that. However, that usage should probably get faded out in future too?
Misc notes:
* Fixed compiling error with constaints from harkyman's Maintain Volume patch.
* Subversion of 2.52 now bumped up to .2
Bugfix #21255: Clear track operator did not remove TrackTo constraints too. This could still be made to do Locked Track and other tracking constraints later too, but for now this will do.
