* The emitter object's inverse matrix wasn't in global coordinates during rendering, so the surface normals of the hair emission locations were transformed with the wrong matrix.

This fixes bug #26764 and several others like it, where modifier
properties (and others, but most visibly modifiers) would not do
anything when animated or driven, as modifier properties require the
RNA update calls to tag the modifiers to get recalculated.
While just adding a call to RNA_property_update() could have gotten
this working (as per the Campbell's patch attached in the report, and
also my own attempt #25881). However, on production rigs, the
performance cost of this is untenatable (on my own tests, without
these updates, I was getting ~5fps on such a rig, but only 0.9fps or
possibly even worse with the updates added).
Hence, this commit adds a property-update caching system to the RNA
level, which aims to reduce to the number of times that the update
functions end up needing to get called.
While this is much faster than without the caching, I also added an
optimisation for pose bones (which are numerous in production rigs) so
that their property updates are skipped, since they are useless to the
animsys (they only tag the depsgraph for updating). This gets things
moving at a more acceptable framerate.

* Grid distribution isn't really suited for hair, so this is now disabled.
* Setting a jittered distribution with particles/face = 1 now creates particles on the center of faces.
* Quite a bit of cleanup of the whole particle distribution code.

problem and crash
- It turns out we still need the "copyob" still, if for nothing other
than making sure that the unkeyed transforms can get restored. This
was removed originally as I thought that just reevaluating the
animation would work.
- Removed a buggy line of logic that was causing crashes when there
was no animation data. It's better to just assume that if animation
data exists, that something exists there.
- Make Duplicates Real was not clearing data such as the new animation
data or constraints.
|
|
So, it turns out that dupliframes weren't that bad to restore... the
old version didn't do truly accurate transform freezing as it didn't
update ancestors too. However, as a modelling tool, this will probably
suffice.

python functions.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.

* Particle duplis are now always created with render percentage if G.rendering is set.
* This is not yet a perfect solution (hair for example won't yet work correctly), but
it's good to have even partial functionality here until a proper way to handle this
is implemented.
|
|
rendering them was a real mess.
* After countless different bugs particles should now render correctly inside dupligroups.
* Only particles with metaball visualization are still problematic, this is mostly due to the ancient metaball code.
* I'll also add a test file for some of the situations, so that hopefully these cases stay fixed :)

also removed unnecessary NULL checks (where the pointer was used later without checking).

MAKE_ID, FILE_MAXDIR, moved the generic defines to BLI_utildefines.h.
no functional changes.

Surprising this wasnt noticed in a much more obvious case:
- Key Location, Move, Rotate, Undo-Rotate >> Resets to keyed location as well.
This was happening because DAG_on_load_update() was called on read_undosave(), flagging 'ob->adt->recalc |= ADT_RECALC_ANIM;'
Fix by adding an option to DAG_on_load_update(), not to recalculate time flags.

where normalized quat was incorrectly assumed.
This would have made bug #25003 very simple to find.
- Objects had their quats normalized when calculating their matrix, this is inconstant with pose bones and isn't useful for animation.
Also it wasn't normalizing the delta rotation so these would give bad rotations.
- Converting between rotation modes BKE_rotMode_change_values() assumed normal length quat. changing quat to euler rotation for eg could change the bone.
- Clear rotation and transform were not normalizing the quat when 4d loc was disabled on quat rotation, corrected and also made it so the quat scale is restored after conversion so animations curves dont jump.
There is 1 case in mat3_to_quat_is_ok() where quat_to_mat3 on an unnormalized quat is needed, for this I had to add an ugly static function quat_to_mat3_no_assert(), but overall its worthwhile IMHO to be able to find incorrect use of rotation conversion.

- 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.

Quaternion interpolation was skipped which gave ugly stepping with the curve modifier (broke with my curve twist fix)
|
|
|
|
* The hair strands that were cut based on the texture weren't properly checked for in the duplication code.

Fix #21498: Edit curve Shape key /252_r 27318
Added full support of shape keys for curves and nurbs surfaces including
topology changing in edit mode, undo stuff, updating relative keys when
working under basis and so on.

- if a group has one or more objects in it, it gets a refcount of 1 on load (unchanged from before)
- dupli-groups, and materials no longer add/remove a reference.
- now groups are only freed when they contain no objects or when manually unlinked.

calculation process
This works by tricking the depsgraph into giving us a smaller list of objects to evaluate, with all the necessary objects + their dependencies at the start of the list.
On any complicated setup where non-object parameters need to be referred to (i.e. by drivers) to affect an object's transform, these optimisations will fail and the old (slower) method is still the best way (modify the ifdef and comment out the optimise depsgraph call to do so). However, we'll assume that these aren't too common in real productions, so things should be fine with these fixes. If there really is a need for both, then global options to control these things could follow.
