Quite harmless, but was lazy code...
When you choosed "Vertex Color Paint" material, the init_render_material()
also set the "Vertex color Light" option, because that flag was checked on
during render to detect vertex colors.
Now it has proper checks in render code.
a single object, but was still called outside of that scope. Caused crashes
for example when editing Ipo curves of action keys.
editaction.c and editnla.c still need to be tackled...
Transparent shadow could accidentally intersect first with a face being
farther away, due to the fact larger faces can fill up multiple octree
nodes. Had to use the same exception handling as for raytracing mirror or
glass.
This fixes the active object in place when orbiting the view.

Image Memory Grabage Collection
This adds memory handling to the image code. An image is tagged each time it is used.
During a collection cycle (frequency of cycles is user defined), if an image is older
than a user defined limit, its buffer gets deallocated. This also applies to gl memory buffers.
Images that are loading in GL memory needs to go through two time outs before being fully deallocated: the first time out deallocated the gl memorry, the second the buffer in ram.
Notes:
Image buffer loaded from python gets tagged as permanent upon load. That tag is removed when python stops using the image.
I might have missed some tagging spots, especially in the rendering pipeline. Someone with more knowledge about this code should check to be careful.
Tagging is done on every access, for rendering, this will probably be a performance hit. A scheme should be developped to only tag when the rendering is completed.
Collecting is called in draw_object, most likely not the best place to do it.
Safe from undo, since using undo deallocates memory anyway (like when loading a blend file with one currently opened)
Userpref DNA changes:
I've changed a couple of flagging variables from short to int. Some because they needed more space, others to keep SDNA happy.
Info window changes:
I've grouped a couple of buttons in aligned blocks and changed the color of mutually exclusive options to make them clearer.
Matt didn't do any changes on that in tuhopuu, so hopefully I'm not stepping on anyone's feet with this.
Also changed double constants into floats with f in a couple of places (mostly space.c) to make compiler happier.
Aim was to get a total refresh of the animation system. This
is needed because;
- we need to upgrade it with 21st century features
- current code is spaghetti/hack combo, and hides good design
- it should become lag-free with using dependency graphs
A full log, with complete code API/structure/design explanation
will follow, that's a load of work... so here below the list with
hot changes;
- The entire object update system (matrices, geometry) is now
centralized. Calls to where_is_object and makeDispList are
forbidden, instead we tag objects 'changed' and let the
depgraph code sort it out
- Removed all old "Ika" code
- Depgraph is aware of all relationships, including meta balls,
constraints, bevelcurve, and so on.
- Made depgraph aware of relation types and layers, to do smart
flushing of 'changed' events. Nothing gets calculated too often!
- Transform uses depgraph to detect changes
- On frame-advance, depgraph flushes animated changes
Armatures;
Almost all armature related code has been fully built from scratch.
It now reveils the original design much better, with a very clean
implementation, lag free without even calculating each Bone more than
once. Result is quite a speedup yes!
Important to note is;
1) Armature is data containing the 'rest position'
2) Pose is the changes of rest position, and always on object level.
That way more Objects can use same Pose. Also constraints are in Pose
3) Actions only contain the Ipos to change values in Poses.
- Bones draw unrotated now
- Drawing bones speedup enormously (10-20 times)
- Bone selecting in EditMode, selection state is saved for PoseMode,
and vice-versa
- Undo in editmode
- Bone renaming does vertexgroups, constraints, posechannels, actions,
for all users of Armature in entire file
- Added Bone renaming in NKey panel
- Nkey PoseMode shows eulers now
- EditMode and PoseMode now have 'active' bone too (last clicked)
- Parenting in EditMode' CTRL+P, ALT+P, with nice options!
- Pose is added in Outliner now, with showing that constraints are in
the Pose, not Armature
- Disconnected IK solving from constraints. It's a separate phase now,
on top of the full Pose calculations
- Pose itself has a dependency graph too, so evaluation order is lag free.
TODO NOW;
- Rotating in Posemode has incorrect inverse transform (Martin will fix)
- Python Bone/Armature/Pose API disabled... needs full recode too
(wait for my doc!)
- Game engine will need upgrade too
- Depgraph code needs revision, cleanup, can be much faster!
(But, compliments for Jean-Luc, it works like a charm!)
- IK changed, it now doesnt use previous position to advance to next
position anymore. That system looks nice (no flips) but is not well
suited for NLA and background render.
TODO LATER;
We now can do loadsa new nifty features as well; like:
- Kill PoseMode (can be option for armatures itself)
- Make B-Bones (Bezier, Bspline, like for spines)
- Move all silly button level edit to 3d window (like CTRL+I = add
IK)
- Much better & informative drawing
- Fix action/nla editors
- Put all ipos in Actions (object, mesh key, lamp color)
- Add hooks
- Null bones
- Much more advanced constraints...
Bugfixes;
- OGL render (view3d header) had wrong first frame on anim render
- Ipo 'recording' mode had wrong playback speed
- Vertex-key mode now sticks to show 'active key', until frame change

Recurring issue, but also bug in 2.37/37a: OSA sample amount versus AO
sample amount conflict... if AO and OSA amounts were exact equal it gives
black spots. Solution not optimal yet... but at least looks good.
Still think it's useless to sample fewer than AO level 8 (64), but
nevertheless. :)
Ortho render didn't correct texture/shadow coordinates for subpixel
position. Caused small errors where faces intersect each other.
Also found texture subpixel error in unified (using jitter table not
correctly). This also caused errors with z value comparing.
alone with the following flags :
-Wall -Wno-char-subscripts -Wno-missing-braces.
the only one still worrying me is in rand.c line 57 :
rand.c:57: integer constant is too large for "long" type
but i have no clue about how correct cross-compiler and 32/64 bits friendly
see also my mail to commiter list for signed/unsigned issues
Area light soft shadow now renders transparant shadow as well.
ALso: found error in correct threadsafe use of soft shadow tables. Caused
dither/noise not to look as well as it could.
Thread render with using Area lights was not fully thread safe yet. I
thought I had a smart method to trick threads, but apparently it can best
(and only) be done with Mutexes...
parameters the material preset menu won't be as useful. Both glass presets will look the same
because there is no 'filter' parameter in the old yafray for instance.
So using the new Blender version with an old yafray version should work a bit better,
though the other way around, using the new yafray with an old blender version, will generally
not work as well.
I added a few extra things. In 'yafray' panel re-arranged some buttons, and added a new
button 'Clamp RGB'. This button will be enabled by default and helps to improve AA on
high contrast edges in the image. When using bokeh however, it is best to switch this off,
otherwise lens shaped highlights will be quite a bit less visible.
Changed the 'extinction' parameter name to the probably more correct term 'absorption',
though mathematically it works out the same. Also changed the behaviour of this color,
it no longer specifies a color that will be removed as I wrote in the previous commit,
but instead the actual color at one (blender) unit of distance. The 'Ds' (distance scale)
button below the color sliders controls the scaling of this unit distance.
What this means is that if you take the standard blender cube, which covers two units of
distance by default, setting the distance scale button to 2.0 will make sure that the color
you specified is exactly that color at that distance (provided the base color itself is white
of course, or 'filter' is 0, otherwise it will be filtered by the base color too).
Beyond this distance the color will get darker.
The glow option for point/soft/sphere lights has a new parameter 'GloOfs', or glow offset.
Setting this to a higher value then 0 will soften the central peak of the glow.
Another unreported bug fix: For xml export, when yafray failed to render the xml file
for some unknown reason, or because of other problems, the export code would still load
the previously rendered image, this causes problems however if the image resolution is
not the same as the current Blender buffer, and so could cause memory corruption or crashes.
This is now taken into account.
World image backgrounds now use the blender mapping settings as well, but only the
'AngMap', 'Sphere' and 'Tube' settings. But in yafray those last two, unlike Blender, cover
the whole view, not just the upper half, so is not really fully compatible with yafray.
So now you have to set one of these buttons too when loading a hdr lightprobe image.
btw, something I forgot to mention in previous commits is that the exposure control using
the texture brightness slider is no longer restricted to integer values. It is now a
floating point value, so you're not restricted to the 0 1 and 2 slider positions anymore,
anything in between will work too.
And finally, display updating is now more like Blender, using the mouse cursor as frame
counter for animation, etc.
the edge of an image. It should not be clipped, but comparisions with
floats then can go wrong... here the FLT_EPSILON is to the rescue.
/* smallest such that 1.0+FLT_EPSILON != 1.0 */
#define FLT_EPSILON 1.19209290e-07F
(Bug fix#2610)
- The ortho render recode had a weak method to calculate the Z value of the
render coordinate (shi.co[2]). Worked OK for normal render, but not in
unified, giving big errors in Ortho Unfied render.
Solved with proper math, using face equation a*x+b*y+c*y=d. Dunno why I
didn't do it in first place. :)
- Bug fix#2493. Edge render gave much different result for Ortho. This
was due to overflows in the integer math filtering zbuffer values.
Cleaned it op properly, preventing any integer overflow now.
source/creator/creator.c
changed ifdef's around fpe_handler to match when its actually used.
intern/SoundSystem/intern/SND_AudioDevice.cpp
Changed: SND_SoundObject* oldobject = oldobject = pIdObject->GetSoundObject();
to: SND_SoundObject* oldobject = pIdObject->GetSoundObject();
intern/SoundSystem/openal/SND_OpenALDevice.cpp
removed unused var.
source/blender/blenkernel/intern/mball.c
initalized a couple of vars that might have been used uninitalized.
The rest were changing types to match, most of them were something like
was short * should have been unsigned short *.

MSVC 6.0 Projectfile changes for zblur and new files in ketsji.
Also adding BL_src projectfile to the commit, apparently it's not up to date with transform_conversions.c but I have it ok here and don't get any diffs.
submitted by Alexander, changes/improvements are:
- Moved to new Panel in Scene buttons "Post Effects". Together with other
postprocessing options, such as Edge render. It is also not called DoF,
this because that's a bit pretending too much then. It's a zblur still!
- Made it render Alpha as well
- Made it use and deliver float buffers
- Huge cleanup of zblur.c code, was very messy. It was alling things in render
code without need even (win matrices, transform faces, etc)
- Fixed errors in using Z values (zbuffer is signed int)
- Removed very weird gamma corrections for front/back half
- Tweaked gaussian table, allow variable 'Sigma' to be set for gauss curve
- Didn't copy 'auto focus' yet. Use of this is very limited, and gives
false expectations, nor works for rendering anims with deamons well.
Main issue remains: it's not a very advanced feature... I still doubt
very much if this deserves to be released. Spent 2 days on trying to get
the key issues solved, with not much results.
- gauss filter code has weird side effects on large blur size
- having unsharp (blurred) in front also blurs what's around in back.
only blurred in back with sharp in front works a little bit
- severe aliasing errors... also due the code splitting in 2 halves
- doesnt work with unified yet
- won't work for halos, spot halos or transparant faces
Anyhoo... It was promised to be committed, so now artists can play with it.
Who knows it's useful after all, or some fixes can be implemented. :)
- Maximum faces/halos per pixel was 500, which wasn't correctly applied in
all cases, causing errors in AA
- Moved maximum up to 1000 now
- made halos become clipped away from filling in buffers when behind a
solid face. That saves a lot of rendertime!
Unified remains weak with halos...
This will add Minneart diffuse and WardIso specular to our shader menu.
Minneart gives nice control over darkness/brightness areas, the wardIso
over 'plastic' style sharp or fuzzy specular.
Webpage is being made with nice samples. Will be in release log.
Jorge: one change is in the do_versions, you inserted it on wrong location.
The addition in 2.36 to correct bumpmapping for View and Object rotation,
made many nice bumpmap setups in older files less nice. Especially apparent
when you apply "flipped" mappings in "Map Input" Panel, like map the X to Z
and the Z to X. A correction then gives wrong results.
Since the "correct bumpmapping" is actually a new option, causing extra
rendertime too, I've made it an option now. With the "Map To" Panel being
fully used, I've put the new button option (temporally I hope) in the first
"Texture" Panel in material context.
Will be updated in release log page!
(Looks like big commit, but is mostly just change of API call!)
Particle emittors now can be parented to an armature Bone, and give the
correct path for each particle. Note that this doesn't work for deform!
And, for each particle the entire armature is evaluated, all actions and
NLA strips.
It used to work a little while BTW, but the code just called ALL armatures
and made ALL deforms again. Was quite slow... thats why the API call
change: do_all_actions() now accepts Object * to only do that one. With
a NULL it now does all still. Will disapppear in recode of course...
Envmap rendering was using Gauss filtering, causing dark outlines in edges
of cube pictures. Now it temporally disables gauss in envmap render, which
isn't really noticable since the pics are filtered + gaussed anyway in the
end result.
Underflow case in Blinn spec... resulting in large negative values to be
returned in certain cases, causing (again!) black dots.
Thanks randall for clear report with nice demo file. :)
With a sun lamp shining exact perpendicular to a face, the result was
undefined (black or full lit). Was caused by using acos() without checking
the input range. Float calculus can result in small under or overflows...
therefore: always use the arithb.c function saacos() !!!
Found more acos() usage in rendercore (in blinn and arealight too), removed
all of them. Might solve the white or black dots people were complaining
about?
- cancelled previous commit to add RE_findTFAce, instead just added
a MemArena to render struct... free'd at end of render, can be used
to store other data as well
- switch rendering to using DerivedMesh API... this is slightly more
inefficient now because it is doing some unnecessary copying. Can
be fixed by defining a DerivedMesh function to convert the object
into a render object (on todo list)
are owned by mesh (or displistmesh)... this causes problems for
adapting to systems that build tfaces on the fly. Added RE_findTFace
function to allow allocating tfaces inside renderer itself.
The gamma functions in gammaCorrectionTables.c cannot be used to correct
and correct back with identical results... causing banding in rendering
pictures with halos.
NOTE: BLI_winstuff.h was meant to be a wrapper around windows.h to handle
undefining various crap that windows.h defines. Platform specific headers
should only have to be included in a few places. This reduces the number
of inclusions of BLI_winstuff.h to 16 which is a much more reasonable
number (than the 144 or whatever it used to be)
- Made framework for 3d Transform Manipulators (widgets)
- The Manipulators act like '2d buttons', by default with LeftMouse and with
while-hold-move-release
- Implemented now: Translation Widget, which allows:
- four hotspots for axis grab or view-aligned grab
- center defined by 'around' setting
- SHIFT+LMB gives planar constraint on other 2 axes
- works in Object mode and Edit mode (not posemode yet)
Enable it with (temporal) icon in 3D header. All other 'normal' transforms
then keeps working btw.
On the todo for this widget:
- choice for Global, Local or Normal orientation
The way the widgets are going to work is in review still. Commit is also for
Matt for his proposal/paper on topic.
Some notes regarding this project;
- no life updates (on mouse over) like 3DS, I think that's neurotic
- on click, dominant axis changes to theme defined "Transform" color, other axes disappear, like maya
- manipulater size is fixed preset, independent zoom.
- manipulator follows selection, and is located based on 'around' mode
Unresolved;
- in maya, when you select 2 or more objects, the manipulator draws on the 'active' object, also interesting
- what to do with G,R,S hotkeys? It could switch the manipulator "mode"...
- header button/menu for manipulator mode?
Halo render had too narrow clipping for left/right or top/bottom part of
image. Was caused by fix for 2.36, incorrect clipping for distance...
distance was OK, but the old hack should be still there for X or Y clip!
Bumpmaps for skin on Env's dinosaurs appeared to be less nice in 2.36. This
was caused by the bugfix to make bumpmapping correct for rotations, which
should only work for flat/cube mapping. It also rotated it for sphere/tube
though, which gives less interesting bumps.
So; now the correction is skipped for tube/sphere mapping bumping.
