Our current keymap doesn't give us enough room to make such changes in
the event system. To fix small issues caused by this, we would need to do
drastic changes in Blender's keymaps and internal handling. It was worth
a try, but it didn't work.
I can write down a more descriptive statement in a few days, but for now
I need a break of this stuff.

resolved bug but wasn't correct
|

Issue was caused by mismatched logic in counting child/parent particles in
job initialization and actual job execution. Confusion here came from mixed
usage of psys->renderdata and G.is_rendering.
We need to get rid of G.is_rendering and use eval_ctx if it's really needed,
but we also might just use psys->renderdata check since it's expected psys
to have this structure anyway.

Speedup is non-linear, 2x-10x faster is quite normal.
Patch T43678.
- Switched from an Octree to BVH.
- Finding first points of surface no longer "wastes" density function evaluation: every result is cached.
- Use MemArena instead of using own memory management.
- Correct calculation of metaelem bounding box.
- Remove mball_count(): mballs are now counted "on the go".

This is an API specifically for the outliner,
not some generic hierarchical hash structure.

* Revert 776bfa64a53191b and c3dad7953afccd4 (some X11 systems are doing
stupid things forcing me to do an extra check that completely breaks the
click type handling on other systems using the slightly changed
implementation from those commits - see T44278)
* Fix sample lines in Compositor+VSE
(And yes, this time I tested on both of my systems to make sure
everything is fine)
|
|
And some general style cleanup as well (line length...).
|
|
Did some bad spacing in recent commits, better to get rid of those so
they does not confuse those who're working on sources.

Originally we thought it's needed in order to distinguish builtin file from
filename which starts with '@', but the filepath is actually full path there
and it's unlikely to have file system where '@' is a proper root character.
Surprisingly this does not give visible speed differences, but it's still
nice to get rid of redundant check.

KX_Scene::addObject: Changed the parameter "other" to "reference", as "other" doesn't mean anything.
KX_Scene::AddReplicaObject: Changed the parameter "parentobject" to "referenceobject", as the parameter did NOT contain a parent object in any way.
Now both functions use the same kind of name for the same thing.
Thanks to panzergame / Porteries Tristan.

Main purpose of this change is to make material preview appearing more
instant after the shader tweaks.
|
|
There were two major problems with the interactivity of material previews:
- Beckmann tables were re-generated on every material tweak.
This is because preview scene is not set to be persistent, so re-triggering
the render leads to the full scene re-sync.
- Images could take rather noticeable time to load with OIIO from the disk
on every tweak.
This patch addressed this two issues in the following way:
- Beckmann tables are now static on CPU memory.
They're couple of hundred kilobytes only, so wouldn't expect this to be
an issue. And they're needed for almost every render anyway.
This actually also makes blackbody table to be static, but it's even smaller
than beckmann table.
Not totally happy with this approach, but others seems to complicate things
quite a bit with all this render engine life time and so..
- For preview rendering all images are considered to be built-in. This means
instead of OIIO which re-loads images on every re-render they're coming
from ImBuf cache which is fully manageable from blender side and unused
images gets freed later.
This would make it impossible to have mipmapping with OSL for now, but we'll
be working on that later anyway and don't think mipmaps are really so crucial
for the material preview.
This seems to be a better alternative to making preview scene persistent,
because of much optimal memory control from blender side.

Implemented Features
====================
Builtin Stereo Camera
* Convergence Mode
* Interocular Distance
* Convergence Distance
* Pivot Mode
Viewport
* Cameras
* Plane
* Volume
Compositor
* View Switch Node
* Image Node Multi-View OpenEXR support
Sequencer
* Image/Movie Strips 'Use Multiview'
UV/Image Editor
* Option to see Multi-View images in Stereo-3D or its individual images
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images
I/O
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images
Scene Render Views
* Ability to have an arbitrary number of views in the scene
Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

It is still possible to free a bit more memory by detecting buildin images
which are not used by shaders, but that's not going to improve memory usage
that much to bother about this now.
Such change brings peak memory usage from 4.1GB to 3.4GB when rendering
01_01_01_D layout scene from the Gooseberry project. Mainly because of
freeing memory used by rather huge environment map in the viewport.

Now even to master
|
|
Seems like a fix that is needed for some X11 systems causes this bug on
others :| Not sure if the systems that needed this fix are now still
fine (since I did a slight change to the click type check procedure),
but I need to check that on my system in the institute in a bit.

This attribute is not really supported for volumes, so it get's converted to
constant 0 at shader compile time.
TODO: We should consider doing the same for tangent attribute in order to save
some annoying checks at tracing time.
|
|
Our own implementation is in fact the same performance as in fast_math from
OpenShadingLanguage, but implementation from fast_math is using explicit madd
function, which increases chance of compiler deciding to use intrinsics.

Just add KM_CLICK to the already sent KM_RELEASE, don't send a new one
for this.
This might help us to get rid of quite some glitches and workarounds \o/
(why didn't this come earlier to my mind? :S)

extruding
More practical description of the bug: extruding with ctrl to use
snapping and confirming the action added another extrusion to the mouse
position.
This was caused from the second event that is now sent if a key release
happens within the click timeout. It triggers the "Extrude to Cursor"
operator since it is called by CTRL+LMB wich is exactly the event that
is sent in this case.
I'm not totally happy with this workaround since it changes the Confirm/
Abort event for all transformation actions to key release which *might*
result in more conflicts (fingers crossed this isn't the case). If this
happens we might need to write some special transformation handling for
extrusion.
This is an example of the difficulties we get from loading too much
functions on the same keys - we need to be careful with that!

|
Was rather harmless typo since we either pass both dx,dy or pass both NULL.
|
|
This patch is based on some work done in D788 and re-formulation from Beckmann
implementation in OpenShadingLanguage.
Skipping texture lookup helps a lot on GPUs where it's more expensive to access
texture memory than to do some extra calculation in threads.
CPU code still uses lookup-table based approach since this seems to be still
faster (at least on computers i've got access to).
This change gives about 2% speedup on BMW scene with GTX560TI.
|
|
It did not preserve stratification too well and lookup-table approach was
working much better. There are now also some more interesting forumlation
from Wenzel and OpenShadingLanguage which should work better than old code.

The character motion actuator local movement does not taking account of the object rotation.
It is necessary to rotate the motion vector before adding the local movement.

Own fault, thanks a bunch to LazyDodo for finding that - and odd
GCC did not warn about it...
