This way we reduce amount of time wasted in spin-lock later on when all threads
are starting to sample texture.
|
|
|
|
Using image pool will reduce number of thread locks when acquiring image.
Useful when it's needed to sample texture fewzillion times a second.

BKE_id_copy_ensure_local function.
|
|
Turns out most BKE_foo_make_local datablock-specific functions are actually doing
exactly the same thing, only two currently need special additional operations
(object and brush ones). So added a BKE_id_make_local_generic instead
of copying same code over and over.
Also, changed a bit how make_local works in case we are localizing a whole library.
We need to do the 'remap' step (from old linked ID to new local one) in the second loop,
otherwise we miss some dependencies. This fixes main part of T48907.

datablocks.
BKE_previewimg_copy() would simply copy PreviewImage's icon_id, without bothering about
ID one.
When we duplicate an ID, we want to reset its icon_id to zero (and regenerate it on-demand),
not keep same icon_id as original, so added new BKE_previewimg_id_copy helper to handle that.

used locally.
Will be used by link/append code.
|
|
Idea looked good, but we have too much custom situations here (some half-fake-sub-ID
being copied with their 'owner', animdata, etc.), let's let datablock copy functions
handle that themselves.
Also allows to safely call BKE_id_expand_local from all copy functions now (only when
copying linked data).

This one is already called by matching copy functions, no need to call it twice!

preview image.
Also cleaned-up/synchronized code across al ID types that support preview.
|
|
Now using modern features from libquery/libremap areas.
Provides same kind of fixes/improvements as for BKE_object_make_local() (see rBd1a4ae3f395a6).

Also allows us to get rid of a few _copy_ex() versions...

Idea is to replace hard-to-track (id->lib != NULL) 'is linked datablock' check everywhere in Blender
by a macro doing the same thing. This will allow to easily spot those checks in future, and more importantly,
to easily change it (see work done in asset-engine branch).
Note: did not touch to readfile.c, since there most of the time 'id->lib' check actually concerns the pointer,
and not a check whether ID is linked or not. Will have a closer look at it later.

handling).
This commit changes a lot of how IDs are handled internally, especially the unlinking/freeing
processes. So far, this was very fuzy, to summarize cleanly deleting or replacing a datablock
was pretty much impossible, except for a few special cases.
Also, unlinking was handled by each datatype, in a rather messy and prone-to-errors way (quite
a few ID usages were missed or wrongly handled that way).
One of the main goal of id-remap branch was to cleanup this, and fatorize ID links handling
by using library_query utils to allow generic handling of those, which is now the case
(now, generic ID links handling is only "knwon" from readfile.c and library_query.c).
This commit also adds backends to allow live replacement and deletion of datablocks in Blender
(so-called 'remapping' process, where we replace all usages of a given ID pointer by a new one,
or NULL one in case of unlinking).
This will allow nice new features, like ability to easily reload or relocate libraries, real immediate
deletion of datablocks in blender, replacement of one datablock by another, etc.
Some of those are for next commits.
A word of warning: this commit is highly risky, because it affects potentially a lot in Blender core.
Though it was tested rather deeply, being totally impossible to check all possible ID usage cases,
it's likely there are some remaining issues and bugs in new code... Please report them! ;)

We have callbacks for that, they also do some checks and help ensure things are done
correctly. Only place where this is assumed not true is blenloader (since here we
may affect refcount of library IDs as well...).
|
|
Idea is, instead of ignoring completely missing linked datablocks, to
create void placeholders for them.
That way, you can work on your file, save it, and find again your missing data once
lib becomes available again. Or you can edit missing lib's path (in Outliner),
save and reload the file, and you are done.
Also, Outliner now shows broken libraries (and placeholders) with a 'broken lib' icon.
Future plans are also to be able to relocate missing libs and reload them at runtime.
Code notes:
- Placeholder ID is just a regular datablock of same type as expected linked one,
with 'default' data, and a LIB_MISSING bitflag set.
- To allow creation of such datablocks, creation of datablocks in BKE was split in two step:
+ Allocation of memory itself.
+ Setting of all internal data to default values.
See also the design task (T43351).

This commit implements point density texture for Cycles shading nodes.
It's done via creating voxel texture at shader compilation time, Not
totally memory efficient, but avoids adding sampling code to kernel
(which keeps render time as low as possible), In the future this will
be compensated by using OpenVDB for more efficient storage of sparse
volume data.
Sampling of the voxel texture is happening at blender side and the
same code is used as for Blender Internal's renderer.
This texture is controlled by only object, particle system and radius.
Linear falloff is used and there's no turbulence. This is because
falloff is expected to happen using Curve Mapping node. Turbulence
will be done as a distortion on the input coordinate. It's already
possible to fake it using nose textures and in the future we can add
more proper turbulence distortion node, which then could also be used
for 2D texture mapping.
Particle color support is done by Lukas, thanks!

I propose to change the environment map render default resolution (600) to 512 (Thanks brecht for the correction... I don't know why I said dpi) (to make it compatible with this script: http://en.wikibooks.org/wiki/GLSL_Pr...cting_Surfaces ) to make cubeMap reflections easier and avoid this error:
invalid envmap size please render with CubeRes @ power of two
unable to initialize image(0) in MAMaterial, image will not be available

This commit mainly:
* Exposes PreviewImage struct in RNA, including ways for user to set images data.
* Adds a new kind of PreviewImage, using a file path and IMB_thumb to get image.
* Adds a new kind of custom icon using PreviewImage, unrelated to ID previews system.
* Adds a python API (utils.previews) to allow python scripts to access those custom previews/icons.
Note that loading image from files' thumbnails is done when needed (deferred loading), not
when defining the custom preview/icon.
WARNING: for release addons who would want to use this, please keep it to a strict minimum, really needed level.
We do not want our UI to explode under hundreds of different flashy icons!
For more info, see also the release notes of Blender 2.75 (http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.75/Addons)
and the example/templates featured with Blender.

The issue was caused by the conflict between preview render which would set
R_NO_IMAGE_LOAD flag on the renderer and texture samplers called outside of
the render pipeline trying to use this flag.
Now the sampler functions accepts extra argument so render pipeline can
still skip image load, but calls outside of the pipeline will nicely load
all the images.
Not cleanest change in the world but good enough to unlock gooseberry team,
and assuming we already had pool passed all over the place it should be all
fine.
Will need to reshuffle arguments into SamplerOptions structure later.

Propper fix reverting most of rB60e70c0c6014e5, which was only partial specific fix.
This code uses generic `BKE_id_lib_local_paths()` func to handle all possible paths.

This commit includes a few things:
* It moves the Rake and Random flags from the brush to the MTex.
* The first change allows mask textures to have independent rake
support.
* Random rotation now has an angle value that controls the width of the
effect from the rake or default angle
* Rake and Random are now supported together.

Yep, at last it's here!
There are a few minor issues remaining but development can go on in
master after discussion at blender institute.

Previously this only worked for some datablocks relevant to rendering, now it
can be used to detect if any type of datablock was added or removed (but not
yet to detect if it was modified, we need many more depsgraph tags for that).
Most of the changes are some function parameter changes, the important parts
are the DAG_id_type_tag calls.
