While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

- no need to allocate client memory up front
- delete unneeded GL calls
- set default alpha test function on exit

nVidia Linux driver reports GL_CONTEXT_PROFILE_MASK = 0, which is a bug.
In that case check for the ARB_compatibility extension.
Non-buggy drivers will continue to use
GL_CONTEXT_COMPATIBILITY_PROFILE_BIT.
Thx to Dr Hackerman for reporting.

Taken from original bmesh-branch but doesn't give useful results
(misses selection flushing).

This time, all tools' code itself.
Not much to say, except that we can also get rid of that OMP caching pre-process ugly stuff
for multires smoothing.
Together with previous commit, we have about 5% average speedup on stroke execution
(though this vary a lot, up to 30% speedup in rare cases, and in even rarer cases some
odd massive slowdowns...).
Tech note: we may want to add 'guided'-similar feature to our BLI_task threaded loop,
I suspect this could explain random massive slowdowns of new code (very rare, but annoying...).

Caused odd white space error in tooltip enum values.

Logic here is weird. Generally, textured drawing overrides
material color unless material uses object color instead?
It doesn't make sense, material color is a material color
whatever the circumstance.
Repeating: idea as always is to push all those options out of per-
polygon callbacks and make decisions such as color enable in the higher
level functions.
|
|
It would be good to get rid of this entirely, ideally decision
about mcols can be taken at material level and not done per face. More
work needs to be done for that to work though.
|
|
Only used for color for now, but we need this for any kind of buffer
updates actually.
This should get rid of some allocation/deallocation, making
vertex painting a bit faster.

This commit adds "Bands Saw" and "Rings Saw" to the options for the Wave texture node in Cycles, behaving similar to the Saw option in BI textures.
Requested by @cekuhnen on BA.

This gives usual nice boost in parallelized sections themselves, on global sculpting stroke
it's a bit hard to say, seems like we have an average 5% speedup, but it varies a lot...
Note that this area is only parallelized when you have a big brush over dense geometry, otherwise
there's no change at all.
As a side note, this commit also factorizes code here, three times nearly the same code, tst...

Vector mapping node was doing some weird mapping of both original and mapped
coordinates. Mapping of original coordinates was caused by the clamping nature
of the LUT generated from the node. Mapping of the mapped value again was quite
totally obscure -- one needed to constantly keep in mind that actual value will
be scaled up and moved down.
This commit makes it so values in the vector curve mapping are always absolute.
In fact, it is now behaving quite the same as RGB curve mapping node and the
code could be de-duplicated. Keeping the code duplicated for a bit so it's more
clear what exact parts of the node changed.

Totally harmless, but let's silence this bpyrna warning in case enum_items
is a DummyRNA_NULL_items, which is by definition empty...

eg:
blender -b --python-exit-code 1 --python script.py --render-anim
This causes blender not to continue parsing command line arguments and exit if the script raises an exception.

Never believe QTCreator when it comes to finding all usages of a func, kids... grep ftw!

use threading or not, instead of threshold.
From recent experience, turns out we often do want to use something else than basic
range of parallelized forloop as control parameter over threads usage, so now BLI func
only takes a boolean, and caller defines best check for its own case.

It fixes the strict weak ordering assertion failure, see : https://support.microsoft.com/en-us/kb/949171.

Also fix inconsistency for freestyle translation - we use IFACE_ everywhere
(TIP_ may be more suited, but let's be consistent first!).

This time, with have over 300% speedup!
But no, this is not due to switch to BLI_task (which 'only' gives usal 15% speedup),
but to enhancement of the algorithm, flatten loop over covariance matrix items now allows
to compute (usually) all items in parallel, instead of having at most 3 or 4 working threads
(with unbalanced load even)...
|
|
Gives the usual 10%-30% speedup on affected functions themselves (BLI_bvhtree_overlap() and
BLI_bvhtree_balance()), and about 2% speedup to overall cloth sim e.g. (measured from
main Cloth modifier func).

bound before setting uniforms
|
|
Also rearranged code here to not issue a draw call (explicit flush) per
face and not set shader per face either when stippled drawing is mixed
with regular drawing. Not good at all for performance.

This snippet creates a white balance modifier for the video sequence editor. It is useful for everyone who likes to set a new white point in the video source (easily via the eyedropper). Just select a point in the source file where you know that it should be white. The algorithm will then shift the colors towards your new white point.
See attached the image for a quick demo.

- BKE_rename_id -> BKE_libblock_rename (always pass valid main)
also rename:

Harmless but irritating... :P

Gives a global speedup of about 5% in smoke simulation (as usual, parallelized chunks themselves
are about 15-25% quicker with BLI_task than with OMP), using a simple setup with two generators
(one from mesh, one from particles), an obstacle and a windfield.

iterations that workers.
When called with very small range, `BLI_task_parallel_range_ex()` would generate a zero `chunk_size`,
leading to some infinite looping in `parallel_range_func` due to `parallel_range_next_iter_get` returning
true without actually increasing the counter!
So now, we ensure `chunk_size` and `num_tasks` are always at least 1 (and avoid generating too much tasks too).
