the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.

Fixes: [#17347] Scaling problems when "Use Translate" is enabled for image strip
|

and corrected a malfunction on audio strips blend mode
from Luca Bonavita (mindrones)
- adds the method "rebuildProxy()" useful to rebuild all the strips at once: the user can do
- adds a BlendModes dictionary under the Blender.Scene.Sequence module: the user can see the blending option with
- adds the getter/setter "blendMode"
- adds a function seq_can_blend in sequence.c as requested by Peter, useful for these purposes but also to solve a bug
after
- the bug is you can apply blend modes to an audio strip that doesn't make sense: changed the test and now you cannot
assign blend mode other than Replace to audio strips
Omitted DNA cleanup part since its only whitespace and Id prefer to have a useful "svn blame" output.

Added serious interlacing to movies opened using ffmpeg.
(Other video decoders to be done)
Rational: deinterlacing, if done seriously _has_ to be done
in YUV-space. Since internal interface first converts data
to RGB we are pretty much lost (and fall back to IMB_filtery
in that case).

[#12106] Memory leak in sequencer (>10MB/frame)
in parts: inner contents of meta strips are freed up after calculation
making more room for the cache.
Actually have to think of a mechanism, that remembers, which output
frames are asked for and caches only those.

This fixes:
[#11745] Blender crashes when changing Scenes on Sequencer`s Strips
containing:
- last_seq was set to null by scene-render
- button handling wasn't very robust (didn't check for null)
- REDRAWBUTSSCENE was missing
|
|
This fixes:
[11750] "Translate" stops working when offset > image size
|
|
This fixes: [#11642] VSE: crash with Speed Control and play head
Special sequence update (holding down left mouse button on a strip)
could lead to a crash when using the speed control effect, since
we didn't check properly for valid cfras (and therefore if
TStripElem is null... )

black/empty
use BLI_join_dirfile which makes sure the slashes are there.

Fixed order of operation in 3-way color corrector according to
http://rebelsguide.com/forum/viewtopic.php?t=810
Thanks to mindrones for pointing this out.

(not the directory name) to fix bug [#10566] File Open Dialog replaces '#' with '0' in directory names.
removed frame numbering from BLI_convertstringcode into its own function (BLI_convertstringframe), many uses of BLI_convertstringcode were passing dummy frames values anyway.
in cases where adding the current frame number to a filename is needed run BLI_convertstringframe(...) after BLI_convertstringcode(...)
There are some cases Im not sure BLI_convertstringframe is needed, these have been commented as todo, but at least have the same functionality they used to.

number.
somefile_##.png -> somefile_01.png
somefile_########-image.png -> somefile_00000001-image.png
Before, A hash at the end of the string would be replaced by a number with 4 characters. This is still default if no #'s are in the string, so nothing has changed.
To use this function from the python api use scene.render.getFrameFilename()

both char and float buffers.
|

Added IPO-support to color strip.
|
|
A lot of fixes for anim_startofs / anim_endofs:
* crashed when striplen was 0 and startstill / endstill still in use
* made it work for Audio (HD and RAM)
* made it work for Image Sequences
* added a new cutting tool, that uses anim_startofs / endofs instead of
startofs / endofs. This is now the default and called "hard cut"
* moved old cutting method to "Shift-K" and renamed it "soft cut"
|
|
Additional fixes to metastrip handling. The code is now even shorter :)
|
|
Fixed a long standing bug in IMB_dupImBuf: refcounter should be better 0
within the duplicated ImBuf...
Finally removed this strange STRIPELEM_META mumbo jumbo.
On a way to asset management: made METAs behave like true input strips:
* proxying should work
* input filter options should work (including transform and color balance :)
* IPOs now work in replace mode
|
|
Fixed a bug with ibuf caching on startstill / endstill.
The new blend modes happened to force start and endstill to be rendered
over and over again. This could get very annoying especially on scene
strips.
We therefore now cache the original start or endstill ibuf seperately
and copy on demand.

the sequencer. This time, actually apply patch to the file before submmiting.

the sequencer.
|

added checks for a camera
Also added an error ob bake if there are no active objects.
|
|
Since mul changed into master gain slider, slightly raised limit, so that
color balance doesn't get too dark.
Fixed crash in float->float color balance.

Fixes [8222] Sequencer crash
Scene didn't work without a proxy anymore... :)

popdown when sync selection is enabled.

Silently destroyed a null check in free_sequence in last commit,
getting old... :)

This adds low resolution proxy support to the blender sequencer, so
that even HD editing should be possible on slower machines.
The proxies are stored as directories of JPEG-files and are only
activated, if you use preview-resolution rendering.
For your final render, just switch back to full resolution and
the original files are used again.
It enables even proxying of whole effect pipelines and scene-strips
(but you have to your own custom directory for file storage then,
since blender has no filename, which could be taken as a sensible
default directory reference)
|
|
C90 compliant. Also fix warning about pointer parameter mismatch.
|
|
New feature: color balance aka 3-way-color-correction aka lift/gamma/gain
on input (folded into byte -> float conversion, so _very_ fast in that case).
Interface is inspired from Rebel CC (but not as complete yet, you can't
choose white and black points right now).
Bugfix: clamp color seperated wave form display correctly.
|
|
Added a faster linear interpolation scaler to IMB_scaleImBuf.
Only handles common cases when we either
enlarge both, width and height or
shrink both, width and height
but that is pretty fast:
* does only blit once instead of two passes like the old code
(fewer cache misses)
* uses fixed point integer arithmetic for byte buffers
* doesn't branch in tight loops
Should be comparable in speed to the ImBuf ..._fast functions at least
for byte-buffers.
For the rather seldom situations that e.g. width is enlarged and height
is shrunken, the old code is still in use.
-------
Also small fix in sequencer: free float buffers on read now.

This fixes several crashes with the new tstripdata_start/endstill.
dupli_seq was cleaned up as well as add_scene_strip (moved to a
seperate function)
New features:
* opacity can be used in replace blend mode
* the scene within in a scene track can be changed now within the panel
Also:
* [#7842] Note: setCodec in FormatTab disappeared...
should be fixed by this. (Not a big change, so I just commit and see :)

Fixed two issues with the sequencer:
* using blend modes with startstill / endstill in combination with IPOs
failed, since there was no room to store the composited result.
(It was stored into the same TStripElem thereby effectively disabling the
effect of the IPO)
If you have no idea, what this is all about:
A common case was: use a single PNG as a title, extrude and try to fade
in / out using IPOs.
* startstill / endstill are always displayed, so that one can change them
also on movie-strips and scene-strips.

Fixed crash with metastrips where ibufs where null...
|
|
forgot to swap input on "Over drop".
|
|
Fixed:
* crash with gamma tabs and blend modes
* crash on rect -> rect_float blend mode input
* alpha over and under have now input swapped
|
|
Bugfix: fixes crash if lowest strip was in blend mode "ALPHA OVER" (combined
with other blends above)
|
|
Added some additional NULL-checks. (se->ibuf can be null, shame on me :)
|
|
Attention! Rather large sequencer rewrite:
* Implemented layer blending using implicit effects. (works like layers
in "The Gimp" or Photoshop.)
* Fixed Space-Bar start-stop in preview windows.
You can start playback using spacebar within a preview-window and it _works_!
* Fixed Flip Y (didn't work for float)
* Fixed premul (didn't work for float)
* Added IPOs to _all_ tracks. In blend-mode REPLACE it drives the
"mul"-parameter in all other blend modes it drives the effect.
* you can meta single tracks.
* moved "mute track" from "M" to "Shift-M"
* added "Shift-L" for "lock track"
* changed inner workings for Metas. Now all ImBufs have to use the
reference counting mechanism. (Only interesting for coders :)
!!! Really important change, that affects current files!
Since you can mute tracks and now there is real layer blending capabilities
in place, I changed the silly behaviour that chose the output track.
Old behaviour: if we have an effect track visible, use the uppermost effect
track. If there is _no_ effect track visible, use the lowest input track.
New behaviour: always use the uppermost track. With blend modes active:
work our way down starting from the uppermost track to the first
"replace"-mode track. This is the way the gimp, photoshop, basically _all_
other applications work...
So if this change ruins your day: please try to fix your files using
"mute". If this doesn't work out, I can still restore the old behaviour,
but I really hope, that this is _not_ necessary!
Rational: most people won't get affected by this change, since you can't
really do anything usefull with the (old) sequencer without at least one
effect track and then you are on the safe side...

Moved status info bar into panels. It was always shown on the wrong place...
Added anim-startofs and anim-endofs, so that one can specify the range of
_input_ that should be used.
There is a subtle difference to start-ofs and end-ofs,
which will show, when you use "Reverse Frames" or "Speed Control". Both
effects operate on the input-range and _not_ on the display range! Now
you can control both in a comfortable way. Only thing missing: a button
to copy start-ofs and end-ofs to anim-startofs and anim-endofs.
(Andy: that was the feature you missed, when storyboarding with the sequencer
and the speed control effect :)
Also: added File-Name and Dir-Name to redirect input as needed.

* Make Lock flag work for metastrips
* Fixes: flags are cleared on exit of metastrips
* Fixes (hopefully): red picture on big endian

Reworked image / movie loading, to add the following features:
- Mute strip
- Lock strip (peach request :)
- Crop / Translate _before_ image rescaling
- N-keys editing of start, startofs, endofs, startstill, endstill
Added (currently disabled) data structures for
- proxy support
- strip blend modes (currently only "REPLACE" works, which always did :)
Planed:
- automatic FPS rescaling
- command keys to lock/mute a bunch of selected strips
(which would complete the peach request to lock tracks)
Caveats: now the N-keys dialog is four-tabbed. I think, we should move those
tabs into the panels dialog in the future...

|
Fixed IPO calculation for threaded prefetch rendering. (do_seq_ipo used
global CFRA tststs...)
|
|
Added malloc mutex handling. (Sorry, had to patch threads.c a bit,
since otherwise scene tracks will completely screw things up...)
|
|
- Seperated StripData into
StripData
TStripData
where StripData holds only image-filenames and TStripData holds
the working information needed for ImBuf caching.
=> Large drop in memory usage, if you used a lot of movie and meta strips.
=> Fixed bugs in "duplicate" on the way (imbufs where copied around without
taking reference counting seriously...)
=> Code is much cleaner now
- Added defines for TStripData->ok
Finally figured out, what the magic values ment and named them properly :)
- Got rid of Sequence->curelem.
Reason: very bad idea(tm) for multi threading with more than one render
thread. Still not there, but this was a real show stopper on the way.
