Problem was in fact slightly wider, File space was nearly not taking into account
library navigation case and its 'virtual' directoris, except in a few places.
Add a wrapper around BLI_is_dir that also check for lib paths, and used it in
ED_file_change_dir(), such that we now always check path is a
valid directory - in the filebrowser context, not filesytem context. ;)
You can capture and stream video in the BGE using the DeckLink video
cards from Black Magic Design. You need a card and Desktop Video software
version 10.4 or above to use these features in the BGE.
Many thanks to Nuno Estanquiero who tested the patch extensively
on a variety of Decklink products, it wouldn't have been possible without
his help.
You can find a brief summary of the decklink features here: https://wiki.blender.org/index.php/Dev:Source/GameEngine/Decklink
The full API details and samples are in the Python API documentation.
bge.texture.VideoDeckLink(format, capture=0):
Use this object to capture a video stream. the format argument describes
the video and pixel formats and the capture argument the card number.
This object can be used as a source for bge.texture.Texture so that the frame
is sent to the GPU, or by itself using the new refresh method to get the video
frame in a buffer.
The frames are usually not in RGB but in YUV format (8bit or 10bit); they
require a shader to extract the RGB components in the GPU. Details and sample
shaders in the documentation.
3D video capture is supported: the frames are double height with left and right
eyes in top-bottom order. The 'eye' uniform (see setUniformEyef) can be used to
sample the 3D frame when the BGE is also in stereo mode. This allows to composite
a 3D video stream with a 3D scene and render it in stereo.
In Windows, and if you have a nVidia Quadro GPU, you can benefit of an additional
performance boost by using 'GPUDirect': a method to send a video frame to the GPU
without going through the OGL driver. The 'pinned memory' OGL extension is also
supported (only on high-end AMD GPU) with the same effect.
bge.texture.DeckLink(cardIdx=0, format=""):
Use this object to send video frame to a DeckLink card. Only the immediate mode
is supported, the scheduled mode is not implemented.
This object is similar to bge.texture.Texture: you need to attach a image source
and call refresh() to compute and send the frame to the card.
This object is best suited for video keying: a video stream (not captured) flows
through the card and the frame you send to the card are displayed above it (the
card does the compositing automatically based on the alpha channel).
At the time of this commit, 3D video keying is supported in the BGE but not in the
DeckLink card due to a color space issue.
Separate the creation of trees from EditMesh from the creation of trees from DerivedMesh.
This was meant to simplify the API, but didn't work out so well.
`bvhtree_from_mesh_*` actually is working as `bvhtree_from_derivedmesh_*`.
This is inconsistent with the trees created from EditMesh. Since for create them does not use the DerivedMesh.
In such cases the dm is being used only to cache the tree in the struct DerivedMesh. What is immediately released once
bvhtree is being used in functions that change(tag) the DM cleaning the cache.
- Use a filter function so users of SnapObjectContext can define how edit-mesh elements are handled.
- Remove em_evil.
- bvhtree of EditMesh is now really cached in the snap functions.
- Code becomes organized and easier to maintain.
This is an important patch for future improvements in snapping functions.
Now CD_SHAPEKEY_INDEX customdata is stored in edit-mode when hooks and vertex parents are used.
This also fixes a bug where undo would loose key-index data.
Move to structs for BM_mesh_bm_to/from_me to avoid passing many argument, which mostly aren't used.
This fixes a lot of things in NLA RNA update handling (which basically did not update anything previously).
There are more update issues with this editor though...
This introduces a snap-context that can be re-used for casting rays into the scene
(by operators such as walk-mode, ruler and transform code).
This can be used to cache data between calls too.
This is a new option for panorama cameras to render
stereo that can be used in virtual reality devices
The option is available under the camera panel when Multi-View is enabled (Views option in the Render Layers panel)
Known limitations:
------------------
* Parallel convergence is not supported (you need to set a convergence distance really high to simulate this effect).
* Pivot was not supposed to affect the render but it does, this has to be looked at, but for now set it to CENTER
* Derivatives in perspective camera need to be pre-computed or we shuld get rid of kcam->dx/dy (Sergey words, I don't fully grasp the implication shere)
* This works in perspective mode and in panorama mode. However, for fully benefit from this effect in perspective mode you need to render a cube map. (there is an addon for this, developed separately, perhaps we could include it in master).
* We have no support for "neck distance" at the moment. This is supposed to help with objects at short distances.
* We have no support to rotate the "Up Axis" of the stereo plane. Meaning, we hardcode 0,0,1 as UP, and create the stereo pair related to that. (although we could take the camera local UP when rendering panoramas, this wouldn't work for perspective cameras.
* We have no support for interocular distance attenuation based on the proximity of the poles (which helps to reduce the pole rotation effect/artifact).
THIS NEEDS DOCS - both in 2.78 release log and the Blender manual.

This patch specifically dates from March 2015, as you can see in the code.blender.org post. Many thanks to all the reviewers, testers and minor sponsors who helped me maintain spherical-stereo for 1 year.
All that said, have fun with this. This feature was what got me started with Multi-View development (at the time what I was looking for was Fulldome stereo support, but the implementation is the same). In order to make this into Blender I had to make it aiming at a less-specic user-case Thus Multi-View started. (this was December 2012, during Siggraph Asia and a chat I had with Paul Bourke during the conference). I don't have the original patch anymore, but you can find a re-based version of it from March 2013, right before I start with the Multi-View project https://developer.blender.org/P332

Steps to reproduce fixed glitches were:
* Change any editor to be file browser from menu, Ctrl+O *from the file browser area*, Esc -> area reset to what it was before changing to file browser initially
* Ctrl+O from any area, F12, Esc -> returns to initial editor in full-screen (expected is file browser in full-screen)
Fixes T46229
Core of the fix is removing old area from spacedata list when going back to previous area (see ED_area_prevspace -> BKE_spacedata_remove). Also, when creating a new temp area we now don't exit old area anymore (needed so SpaceFile->op is kept, but it also makes sense in general)
Aaand finally removes some ugly hacks.
Tested quite a bit, so I think it's safe to apply (besides of remark below), just would like to get things double checked and confirmed. After all, this full-screen stuff finally starts to feel like it's working :P
Note, there's still a memory leak when quitting Blender with temp area open. Haven't found out how to solve yet, but it's not that important for review anyway.

The main purpose of such linking is to make Blender compatible with
NVidia's debuggers and profilers which are doing some LD_PRELOAD
magic to intercept some function calls. Such magic conflicts with
our CUDA wrangler magic and causes segmentation faults.
The option is disabled by default, so there's no affect on any of
artists.
In order to make Blender linked directly against CUDA library use
the WITH_CUDA_DYNLOAD CMake option (it's marked as advanced).
The idea is to split them into two separate targets and have dedicated include
directories list for each of them in order to avoid some annoying include header
modifications in comparison with upstream.

It also fixes another issue (crash) related to symmetric editing.
Quite involved, we (try to!) fix complete broken logic of parts of particle code, which would use poly index
as tessface one (or vice-versa). Issue most probably goes back to BMesh integration time...
This patch mostly fixes particle editing mode:
- Adding/removing particles when using generative modifiers (like subsurf) should now work.
- Adding/removing particles with a non-tessellated mesh (i.e. one having ngons) should also mostly work.
- X-axis-mirror-editing particles over ngons does not really work, not sure why currently.
- All this in both 'modes' (with or without using modifier stack for particles).
Tech side:
- Store a deformed-only DM in particle modifier data.
- Rename existing DM to make it clear it's a final one.
- Use deformed-only DM's tessface2poly mapping to 'solve' poly/tessface mismatches.
- Make (part of) mirror-editing code able to use a DM instead of raw mesh, so that we can mirror based on final DM
when editing particles using modifier stack (mandatory, since there is no way currently to find orig tessface
from an final DM tessface index).
Note that this patch is not really nice and clean (current particles are beyond hope on this side anyway),
it's more like some urgency bandage. Whole crap needs complete rewrite anyway,
BMesh's polygons make it really hard to work with current system (and looptri would not help much here).
Also, did not test everything possibly affected by those changes, so it needs some users' testing & validation too.

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

This is so called "seems to work in dry tests" commit which is aimed to switch
linux release environment to CMake.
Some notes:
- There's no special handle of libstdc++, but it wasn't really static for quite
some time in SCons configuration and nobody really complained.
- It was quite tricky to get OpenMP linked statically with just using some
configuration so we went ahead and added a special option to CMake now which is
only exist on Linux and advertised as shouldn't be used.
- Packing is happening manually in slave_pack.py. This is because we have to add
some really special files to the archive (mesa libraries for example) which we
can't really handle from CMake/CPack in a nice generic way.
Don't think it's bad approach, at least crappynness is localized and it's not
_that_ crappy anyway.
- Windows buildbot should keep working, but needs doublechecing. It's just a
build folder changed, but you never know what it might imply.
- Some further tweaks are likely needed to ensure all builders are working.
Thanks Campbell for assistance in this patch!
This was getting very hard to follow,
- mixing input/output args.
- mixing arg order between functions.
- arg names (mode, snap_mode) rename to (snap_to, snap_select)
