Made the system around splines order a bit smarter, so
crating a segment between two splines wouldn't switch
direction if splines are selected in a way that they're
"co-linear".
It is possible to make things even smarter using active
point and so, but that i'd consider a TODO.
There were several issues with how bounding box and texture space
are calculated:
- This was done at the same time as applying modifiers, meaning if
several objects are sharing the same curve datablock, bounding
box and texture space will be calculated multiple times.
Further, allocating bounding box wasn't safe for threading.
- Bounding box and texture space were evaluated after pre-tessellation
modifiers are applied. This means Curve-level data is actually
depends on object data, and it's really bad because different
objects could have different modifiers and this leads to
conflicts (curve's data depends on object evaluation order)
and doesn't behave in a predictable way.
This commit moves bounding box and texture space evaluation from
modifier stack to own utility functions, just like it's was done
for meshes.
This makes curve objects update thread-safe, but gives some
limitations as well. Namely, with such approach it's not so
clear how to preserve the same behavior of texture space:
before this change texture space and bounding box would match
beveled curve as accurate as possible.
Old behavior was nice for quick texturing -- in most cases you
didn't need to modify texture space at all. But texture space
was depending on render/preview settings which could easily lead
to situations, when final result would be far different from
preview one.
Now we're using CV points coordinates and their radius to approximate
the bounding box. This doesn't give the same exact texture space,
but it helps a lot keeping texture space in a nice predictable way.
We could make approximation smarter in the future, but fir now
added operator to match texture space to fully tessellated curve
called "Match Texture Space".

* deselect all no longer leaves an active point
* the most recently added spline becomes the active one
* on successful duplicate/delete the active point and active spline are reset
Added surface support to recent curve split operator, completing quick hack todo
Updated nurbs separate operator to make use of new split logic, completing tools todo
Added 'Delete segment' option to surfaces and improved surface duplication, used for split/separate
- rename curve delete operator vertices enum to match mesh delete operator.
- add missing NULL checks to view3d_lock_poll() to prevent crashes when called outside a view3d.
- remove delete-all option (users can just select all and delete as with all other modes).
- remove CALLOC_STRUCT_N macro.
- CURVE_OT_delete define a dynamic enum rather then a custom invoke menu function.
- add support for using the active point's orientation.
- add support for creating new custom orientations from curves.
- fix error where only the last selected curve handle was taken into account for manipulator orientations.
Issue goes back to 2.4x days at least (but very much likely the
issue is even older). It's caused by subdivision code was starting
to iterate points from previous one, which shifted all the points
by one.
Reshuffled code so now iteration starts from first spline point.
Thanks to Campbell for review and tests! :)
Used slightly different approach from what was discussed with Campbell,
and the reason of this is slightly better support of curve point animation
re-mapping.
There're actually some limitations which better be discussed bewfore 'b':
- If there're no point animation, spline separation goes just fine.
- If there're animated points in the curve, blender will preserve
animation for currently editing curve. But, since new curve created
by Separate operator shares the same AnimData, it'll be animatied
in a weird way.
So not sure whether it's better to preserve animation for current spline
but require switching animationdata for new spline or resetting animation
for current curve's animation data.
generator with a local one. It's not thread safe and will not give repeatable
results, so in most cases it should not be used.
Also fixes#34992 where the noise texture of a displacement modifier was not
properly random in opengl animation render, because the seed got reset to a
fixed value by an unrelated function while for final render it changed each
frame.
This simply adds a third "translation type" (in addition to iface and tip), "new data", with relevant user settings flag and helper funcs/macros (and py api).
Currently implemented name translation when adding new objects, as well as modifiers and constraints, will add the others (cd layers, scenes, perhaps nodes [though I think they do not need this], etc.) later.
Without this, bezier curves at 12 resolution are very high detail for many tasks when converted from freehand strokes.
so add the option to convert 1:1 grease pencil points to curve polygons.
also add use_handles option to curve conversion which is used when converting beziers to poly lines.
besides performance in some cases.
* DAG_scene_sort is now removed and replaced by DAG_relations_tag_update in
most cases. This will clear the dependency graph, and only rebuild it right
before it's needed again when the scene is re-evaluated.
This is done because DAG_scene_sort is slow when called many times from
python operators. Further the scene argument is not needed because most
operations can potentially affect more than the current scene.
* DAG_scene_relations_update will now rebuild the dependency graph if it's not
there yet, and DAG_scene_relations_rebuild will force a rebuild for the rare
cases that need it.
* Remove various places where ob->recalc was set manually. This should go
through DAG_id_tag_update() in nearly all cases instead since this is now
a fast operation. Also removed DAG_ids_flush_update that goes along with
such manual tagging of ob->recalc.
Old fixes, since 2009 and before! Related to Curve object editmode:
- normals are not being drawn for hidden curves anymore
- even worse: Blender also didn't hide the extrusions or bevels for hidden curves
- outside edit mode, it shows all (as for all other modes)
- (de)select-all now works when 1st (or any) handle was hidden.
