- 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.
Added a system for running a callback on all the ID-blocks referenced by constraints (like for modifiers). Also, added an API function which calls these on the constraints present in the given list.
These could be used for:
- the proxies + action/pyconstraint fix that campbell committed
- simplification of file loading code
Made the 'Offset Factor' setting use a separate variable from the 'Offset' setting in the DNA stuff. While we could get away with this sort of thing in the past, it turns out that with the Datablocks viewer these days, settings sharing an internal var but with different ranges/behaviour doesn't work well anymore, since later instances override earlier ones.
I've removed editmesh altogether (other then scanfill, which is
seperate code that happens to reuse the editmesh structures).
The compatibility layer I had written for old editmesh tools
was more trouble then it was worth, though it did help in the
early stages of this project.
There's a fair amount of breakage, and there's bunches of tools
(mostly minor ones) I need to port over still. Biggest ones are
join triangles and loop to region, and spin/screw.
This probably isn't really testable, I'll hopefully have more
work done on this soon, but might not be before next week.
Rotations are now stored internally as radians, while exposing degrees in the UI -
in the graph editor and UI controls. This is done in two areas:
1) Using the unit system to convert RNA data to display as degrees in the UI controls
2) FCurves now use degrees for rotation, so you can edit in the graph editor what
you see in the UI.
All rotation data is consistently accessible in DNA and RNA as radians, degrees are only
used for the UI controls and graph editor.
This commit includes conversions will convert old files (stored data and also fcurve data)
to the new units, hopefully everything should go smoothly!
Part of this also changes a few properties that were hard-coded as degrees before (such
as IK pole angle and brush texture rotation) to also use the same consistent system of
radians (dna/rna) and degrees (ui).
Thanks to Joshua for hints and review here too.
Most likely will not compile for others, I'd appreciate any build errors
and missing files reports (I can never seem to get everything committed
and all the build systems working without help).
Porting over the sculpt/multires tools was a breeze,
thanks goes to brecht for a design that didn't exclude
ngons and was easy to port.
Note that I've not tested externally-backed multires
file support yet. Also, I still need to write version
patch code for some cases.
Some notes:
* Like trunk, topological changes don't update multires right,
so e.g. subdivide will duplicate multires data on the new faces,
instead of subdividing it.
* If you set the debug value (ctrl-alt-d) to 1 it'll turn on
my experiments in speeding up sculpting on higher-res multires
meshes (but note it makes partial redraw not completely accurate).
* There's a bug where you have to go through editmode to get out
of sculpt mode, not sure if I inherited or created this myself.
- Offset parameter of the path constraint has no effect on the animation
- Path animation was being repeated multiple times even though it was not supposed to
