This is a new feature that can make using AO a lot more attractive when rendering
animations with vector blur. It uses the speed vector info calculated in the 'Vec'
speed vector pass, in order to reduce AO samples where pixels are moving more
quickly. There's not much point calculating all those AO samples when the result is
going to be smeared anyway, so you can save a bit of render time by doing
a more noisy render in those areas.
You can use this with a new slider in the Adaptive QMC settings 'Adapt Vec'. The
higher the value, the more aggressively it will reduce samples. 0.0 means no
reduction, and 1.0 reduces one sample per pixel of average displacement for that
pixel. 0.25 or so generally gives decent results, but it depends on how fast things
are moving.
Here's a demo (compare the final blurred result, and render times):

And a less contrived example, a short clip from macouno's 'petunia' bconf animation:

The list of changes (some are fixes):
- Properly horizontally centered tags in all fields (bug?).
- File area does not have trailing space and has leading "File " at
start instead (probably a bug).
- Small separation between to time related fields, space saving.
- Removed colons, for consistency and space saving again.
- Frame field is zero aligned for higher visual stability.
- Marker name shows a rarer name, "<none>" (using <> is typical for cases
in which there is nothing: <none>, <empty>, <blank>, etc).
- Top area for misc info that can be really long (file, note and render date).
- Bottom area for more constantly changing but short ones (marker, SMPTE,
frame, camera and scene).
- Only render date moves a line (when note field is not used), and frame one
moves if no SMPTE (still in same line, so no big jump), for extra visual
stability (marker is fixed, assuming most people would show frame and or
SMPTE).
- ISO 8601 date format for render date, localization independant.

* Fixed crash that occurs when using an unknown constraint type or a Null constraint - missing NULL check
* ClampTo constraint now draws ok again
* Null constraints now get drawn in the stack again
I've finally traced down the causes of several of the bugs which caused PyConstraints to work incorrectly (or not at all).
* Freeing is now done using BLI_freelistN inside the pycon_free function, instead of looping through the targets ourselves. This fixes all of those Memblock free: pointer not in list errors.
* BPY_pyconstraint_update now correctly creates/frees the constraint's targets as needed. Previously, it was creating/removing the wrong number of targets. Also, pyconstraints no longer get disabled when using armatures (not bones)
* The panel drawing was also not working right, as there were still some offset issues.
This occurred when using qmc shadows, full OSA, and sss - it was
assuming full OSA was being used, even when (during the SSS prepass)
osa is set to 0.
Fixed by tightening up the checks for full OSA.
To test for this in Blender, just add text, TAB out of edit mode, then convert to mesh ( ALT+C ), and press P for the game engine. Alternatively select Textured Draw Mode. You'll notice that the text is only visible from the back. This patch reverses this, to be more correct.
Based on discussions on IRC, I'm now trying to fix another aspect of the extrude code - the fact that the faces at the front and back of the extruded curve face the same way ( ie one of them will be wrong ). I'll keep working on this, but if someone can help out, feel free!
* Removed the old get_con_subtarget_name function and fixed the places that used it. This was only suitable for single-target constraints.
* PyConstraints interface drawing should now no longer draw multiple-target fields on top of each other
* Removed double call to BPY_pyconstraint_update when the Update button was clicked. I found this while debugging why PyConstraints didn't seem to be working yet...
* DNA_action_types.h - fixes for typos that broke compiling (own error)
* transform.c - fix for implicit definition of a function (missing header)
* outliner.c - commented out a few unused vars (as a result of constraints refactor)
* editsima.c - fixed uninitialised var warning
* drawview.c - bugfix #7598 load without ui crashes if there is no camera. Patch provided by Daniel Genrich (genscher)
Once again, I've recoded the constraints system. This time, the goals were:
* To make it more future-proof by 'modernising' the coding style. The long functions filled with switch statements, have given way to function-pointers with smaller functions for specific purposes.
* To make it support constraints which use multiple targets more readily that it did. In the past, it was assumed that constraints could only have at most one target.
As a result, a lot of code has been shuffled around, and modified. Also, the subversion number has been bumped up.
Known issues:
* PyConstraints, which were the main motivation for supporting multiple-targets, are currently broken. There are some bimport() error that keeps causing problems. I've also temporarily removed the doDriver support, although it may return in another form soon.
* Constraints BPy-API is currently has a few features which currently don't work yet
* Outliner currently only displays the names of the constraints instead of the fancy subtarget/target/constraint-name display it used to do. What gets displayed here needs further investigation, as the old way was certainly not that great (and is not compatible with the new system too)
This adds fractional FPS support to blender and should finally
make NTSC work correctly.
NTSC has an FPS of 30.0/1.001 which is approximately 29.97 FPS.
Therefore, it is not enough to simply make frs_sec a float, since
you can't represent this accurately enough.
I added a seperate variable frs_sec_base and FPS is now
frs_sec / frs_sec_base.
I changed all the places, where frs_sec was used to my best knowledge.
For convenience sake, I added several macros, that should make life
easier in the future:
FRA2TIME(a) : convert frame number to a double precision time in seconds
TIME2FRA(a) : the same in the opposite direction
FPS : return current FPS as a double precision number
(last resort)
This closes bug #6715
Standard framerates not supported / breaks sync -- 23.967 29.967 etc.

Please give this heavy testing with NTSC files, quicktime in/export
and the python interface.
Errors are most probably only spotted on longer timelines, so that is
also important.
The patch was tested by Troy Sobotka and me, so it most probably should
work out of the box, but wider testing is important, since errors are
very subtle.
Enjoy!
- on unix BLI_diskfree was only using 100 chars for the dir name, and
not checking if the name given was longer, increased to FILE_MAXDIR
(160) and added a check, return -1 if its too long.
The file selector only allowed 80 chars to be typed into the directory
entry.
Made the file selector check that the path is less then FILE_MIXDIR, if
you try and enter a path thats longer it will tell you that the path is
too long, before it was writing into other memory and crashing.
install.
face.uv[:] was returning a blank list. and making smart UV projection script fail.
On one system Python is giving the slice function positive values, whereas on the 64bit system its
passing negative which are then clamped to zero.
made mathutils types accept negative values for slicing. This is very odd because both systems are
running ubuntu gutsy with python 2.5
draws into the
frame.
This patch includes some changes I made...
* use blenders bitmap fonts (rather then own fonts)
* select font size
* user interface layout changes
* Marker as another image stamp option
Also added some new API calls
BMF_GetFontHeight(font);
BMF_DrawStringBuf(...); - so we can draw text into an imbuf's image buffer.
get_frame_marker(frame) - get the last marker from the frame.
IMB_rectfill_area(...) - fill in an image buffer with a rectangle area of color.
TODO - draw stamp info in 3d view, at the moment it just displays in the animation.
This commit makes "Remove Doubles" of w menu to work again.
Also renamed "AutoMarge" to "AutoMerge".
Added shortcut of "Select Inverse" to menus and renamed
"Select/Deselect All" to be consistent with rest of Blender.
/* special hidden feature! shrink to fit */
if (G.rt > 500){
scale = (G.rt - 500) / 100.0f;
}
-- shrink a T shirt to fit .. evil grin
-- by the way i did set up the rule 'if any *outer object* hits no *inner* will be regarded' ... pretty poor IMHO .. well but it works
