Added function called WM_set_locked_interface which does
two things:
- Prevents event queue from being handled, so no operators
(see below) or values are even possible to run or change.
This prevents any kind of "destructive" action performed
from user while rendering.
- Locks interface refresh for regions which does have lock
set to truth in their template. Currently it's just a 3D
viewport, but in the future more regions could be considered
unsafe, or we could want to lock different parts of
interface when doing different jobs.
This is needed because 3D viewport could be using or changing
the same data as renderer currently uses, leading to threading
conflict.
Notifiers are still allowed to handle, so render progress is
seen on the screen, but would need to doublecheck on this, in
terms some notifiers could be changing the data.
For now interface locking happens for render job only in case
"Lock Interface" checkbox is enabled.
Other tools like backing would also benefit of this option.
It is possible to mark operator as safe to be used in locked
interface mode by adding OPTYPE_ALLOW_LOCKED bit to operator
template flags.
This bit is completely handled by wm_evem_system, not
with operator run routines, so it's still possible to
run operators from drivers and handlers.
Currently allowed image editor navigation and zooming.

* EXR layers with names like 'Z' without any pass name were not loaded at all
and would break the Combined pass as well.
* EXR pass names longer than 16 characters where writing past the end of the
array and getting invalid names.
|
|
For example for vector displacement, you may have an EXR texture that has
negative colors values. Blender clamps these by default, now the Colors panel
for textures has a Clamp option to disable this clamping.
This option affects all texture types and is enabled by default, you need
to disable it if you want negative values to have an influence.
Patch by Fredrik Hansson with modifications by me.

This was storing the original object matrix, which builds on the
assumption that obmat is modified during dupli construction, which is a
bad hack.
Now the obmats are still modified, but this only happens outside of the
dupli system itself and the original ("omat") is stored as local
variables in the same place where the obmat manipulation takes place.
This is easier to follow and avoids hidden hacks as much as possible.

This is a regression since threaded dependency graph landed to master.
Root of the issue goes to the loads of graph preparation being done
even if there's nothing to be updated.
The idea of this change is to use ID type recalc bits to determine
whether there're objects to be updated. Generally speaking, we now
check object and object data datablocks with DAG_id_type_tagged()
and if there's no such IDs tagged we skip the whole task pool creation
and so,
The only difficult aspect was that in some circumstances it was possible
that there are tagged objects but nothing in ID recalc bit fields.
There were several different circumstances when it was possible:
* When one assigns object->recalc flag directly DAG flush didn't
set corresponding bits to ID recalc bits. Partially it is fixed
by making it so flush will set bitfield, but also for object
types there's no reason to assign recalc flag directly. Using
generic DAG_id_type_tag works almost the same fast as direct
assignment, ensures all the bitflags are set properly and for the
long run it seems it's what we would actually want to.
* DAG_on_visible_update() didn't set recalc bits at all.
* Some areas were checking for object->recalc != 0, however it is was
possible that object recalc flag contains PSYS_RECALC_CHILD which
was never cleaned from there.
No idea why would we need to assign such a flag when enabling
scene simplification, this is to be investigated separately.
* It is possible that scene_update_post and frame_update_post handlers
will modify objects. The issue is that DAG_ids_clear_recalc is called
just after callbacks, which leaves objects with recalc flags but no
corresponding bit in ID recalc bitfield. This leads to some kind of
regression when using ID type tag fields to check whether there objects
to be updated internally comparing threaded DAG with legacy one.
For now let's have a workaround which will preserve tag for ID_OB
if there're objects with OB_RECALC_ALL bits. This keeps behavior
unchanged comparing with 2.69 release.

Due to float precision issues it was basically random which of the two was used,
now it's slightly biased towards 128, which is the convention for flat colors.
The small difference between 127 and 128 could give problems with sharp glossy
shaders where it would be visible as seams.

didn't need a camera because they use only compositing nodes.

Summary:
Issue was caused by the same tile being written twice to
the EXR file. This was happening because of partial update
of work-in-progress tiles was merging result to the final
render result in order to make color management pipeline
happy.
We need to avoid such a merges and keep memory usage as
low as possible when Save Buffers is enabled.
Now render pipeline will allocate special display buffer
in render layer which will contain combined pass in the
display space. This keeps memory usage as low as we can
do at this moment.
There's one weak thing which is changing color management
settings during rendering would lead to lossy conversion.
This is because render result's display buffer uses color
space from the time when rendering was invoked.
This is actually what was happening in previous release
already actually so not a big issue.

Summary:
Original issue was caused by wring detection of whether
SS modifier is being applied for render/viewport. After
recent dependency graph commit this was no longer an
issue.
But it still might have happen conflict between viewport
draw and scene_update_for_newframe() invoked from render
thread when using external engines like Cycles.
Solved by adding viewport lock while scene is being
updated and objects being exported to the render engine.
Same lock was already used for Blender Internal.

Summary:
Made objects update happening from multiple threads. It is a task-based
scheduling system which uses current dependency graph for spawning new
tasks. This means threading happens on object level, but the system is
flexible enough for higher granularity.
Technical details:
- Uses task scheduler which was recently committed to trunk
(that one which Brecht ported from Cycles).
- Added two utility functions to dependency graph:
* DAG_threaded_update_begin, which is called to initialize threaded
objects update. It will also schedule root DAG node to the queue,
hence starting evaluation process.
Initialization will calculate how much parents are to be evaluation
before current DAG node can be scheduled. This value is used by task
threads for faster detecting which nodes might be scheduled.
* DAG_threaded_update_handle_node_updated which is called from task
thread function when node was fully handled.
This function decreases num_pending_parents of node children and
schedules children with zero valency.
As it might have become clear, task thread receives DAG nodes and
decides which callback to call for it.
Currently only BKE_object_handle_update is called for object nodes.
In the future it'll call node->callback() from Ali's new DAG.
- This required adding some workarounds to the render pipeline.
Mainly to stop using get_object_dm() from modifiers' apply callback.
Such a call was only a workaround for dependency graph glitch when
rendering scene with, say, boolean modifiers before displaying
this scene.
Such change moves workaround from one place to another, so overall
hackentropy remains the same.
- Added paradigm of EvaluaitonContext. Currently it's more like just a
more reliable replacement for G.is_rendering which fails in some
circumstances.
Future idea of this context is to also store all the local data needed
for objects evaluation such as local time, Copy-on-Write data and so.
There're two types of EvaluationContext:
* Context used for viewport updated and owned by Main. In the future
this context might be easily moved to Window or Screen to allo
per-window/per-screen local time.
* Context used by render engines to evaluate objects for render purposes.
Render engine is an owner of this context.
This context is passed to all object update routines.

Summary:
Mainly addressed to solve old TODO with color managed fallback
to CPU mode when displaying render result during rendering.
That fallback was caused by the fact that partial image update
was always acquiring image buffer for composite output and was
only modifying display buffer directly.
This was a big issue for Cycles rendering which renders layers
one by one and wanted to display progress of each individual
layer. This lead to situations when display buffer was based on
what Cycles passes via RenderResult and didn't take layer/pass
from image editor header into account.
Now made it so image buffer which partial update is operating
with always corresponds to what is set in image editor header.
To make Cycles displaying progress of all the layers one by one
made it so image_rect_update switches image editor user to
newly rendering render layer. It happens only once when render
engine starts rendering next render layer, so should not be
annoying for navigation during rendering.
Additional change to render engines was done to make it so
they're able to merge composite output to final result
without marking tile as done. This is done via do_merge_result
argument to end_result() callback. This argument is optional
so should not break script compatibility.
Additional changes:
- Partial display update for Blender Internal now happens from
the same thread as tile rendering. This makes it so display
conversion (which could be pretty heavy actually) is done in
separate threads. Also gives better UI feedback when rendering
easy scene with small tiles.
- Avoid freeing/allocating byte buffer for render result
if it's owned by the image buffer. Only mark it as invalid
for color management.
Saves loads of buffer re-allocations in cases when having
several image editors opened with render result. This change
in conjunction with the rest of the patch gave around
50%-100% speedup of render time when displaying non-combined
pass during rendering on my laptop.
- Partial display buffer update was wrong for buffers with number
of channels different from 4.
- Remove unused window from RenderJob.
- Made image_buffer_rect_update static since it's only used
in single file.

Summary:
Behaves very much the same as cache for Movie Clip datablock:
- Image now have `MovieCache *cache` field which replaced
legacy `ListBase ibufs`.
This allows image datablock to easily keep of image
buffers which are owned by itself. This field isn't
saved to the file and getting restored on undo steps.
However, cache limit is global for movies, sequences
and image datablocks now. So overall cached image buffers
size will not go above cache limit size in user
preferences.
- Image buffers which are marked as BITMAPDIRTY will never
be freed from the cache.
- Added utility function to iterate over image buffers
saved in movie cache.
- Movie cache cleanup check callback now have ImBuf argument
which can be used in a condition of cleanup.
- Added some utility functions which replaces legacy ibufs
iterations with image cache iteration which happens from
inside a lock.
- Fixed `image_mem_size()` which was only counting one of
the buffers if both float and byte buffer present.
Additional notes:
- `BKE_image_get_first_ibuf()` is rather stupid, but direct
access to ibufs->first was also the same stupid idea.
Would consider avoid this function is another project.
- There are some places which doesn't look threadsafe, but
they already were not so much threadsafe anyway before.
So think not a big deal with solving this later.
Finally solves infinite memory usage by image sequences! :)

This patch changes most of the reamining degrees usage in internal code into radians.
I let a few which I know off asside, for reasons explained below - and I'm not sure to have found out all of them.
WARNING: this introduces forward incompatibility, which means files saved from this version won't open 100% correctly
in previous versions (a few angle properties would use radians values as degrees...).
Details:
- Data:
-- Lamp.spotsize: Game engine exposed this setting in degrees, to not break the API here I kept it as such
(using getter/setter functions), still using radians internally.
-- Mesh.smoothresh: Didn't touch to this one, as we will hopefully replace it completely by loop normals currently in dev.
- Modifiers:
-- EdgeSplitModifierData.split_angle, BevelModifierData.bevel_angle: Done.
- Postprocessing:
-- WipeVars.angle (sequencer's effect), NodeBokehImage.angle, NodeBoxMask.rotation, NodeEllipseMask.rotation: Done.
- BGE:
-- bConstraintActuator: Orientation type done (the minloc[0] & maxloc[0] cases). Did not touch to 'limit location' type,
it can also limit rotation, but it exposes through RNA the same limit_min/limit_max, which hence
can be either distance or angle values, depending on the mode. Will leave this to BGE team.
-- bSoundActuator.cone_outer_angle_3d, bSoundActuator.cone_inner_angle_3d: Done (note I kept degrees in BGE itself,
as it seems this is the expected value here...).
-- bRadarSensor.angle: Done.

Summary:
Curve ORCO was not calculating properly for cyclic 2D curves.
- Needed to split vertices for blender internal renderer.
Otherwise it's not possible to map last face to a proper
texture location.
- Needed to tweak curve->mesh conversion to respect cyclic
flag along U direction.
- Removed check for orcodm in curve.c:add_orco_dm since
this code is only called if there're enabled constructive
modifiers on the curve.

information such as light vector from specified Lamp.
For now this provides the following outputs:
- Color
- Light Vector
- Distance
- Shadow
- Visibility Factor
Note: Color output is multiplied by the lamp energy. Multiplication of
color*max(dot(light_vector,normal_vector),0)*shadow*visibility_factor
produces the exact same result as the Lambert shader.
Many thanks to Brecht for code review and discussion!

Skip byte->float conversion if output file format
supports high bit depths but configured to only
output 8 bits per channel.
Gives around 30% speedup when re-exporting movie file
to PNG image sequence here on laptop.
Possible further optimization:
- Skip color space conversion in imbuf_for_write
function if we've got already have buffer in
that space.
This doesn't seem to happen often after tweak
to render result to imbuf.
- Skip black alpha-under if original image is
opaque,
This is a bit tricky to detect.

so that it becomes (1.0, 1.0, 1.0) when AO is disabled.
For materials using AO pass, this makes the material preview and the GLSL

because we usually enable AO when using the AO pass in node tree.
