These should not have any effect on render results, except in some cases with
you have overlapping faces, where the noise seems to be slightly reduced.
There are some performance improvements, for simple scenes I wouldn't expect
more than 5-10% to be cut off the render time, for sintel scenes we got about
50% on average, that's with millions of polygons on intel quad cores. This
because memory access / cache misses were the main bottleneck for those scenes,
and the optimizations improve that.
Interal changes:
* Remove RE_raytrace.h, raytracer is now only used by render engine again.
* Split non-public parts rayobject.h into rayobject_internal.h, hopefully
makes it clearer how the API is used.
* Added rayintersection.h to contain some of the stuff from RE_raytrace.h
* Change Isect.vec/labda to Isect.dir/dist, previously vec was sometimes
normalized and sometimes not, confusing... now dir is always normalized
and dist contains the distance.
* Change VECCOPY and similar to BLI_math functions.
* Force inlining of auxiliary functions for ray-triangle/quad intersection,
helps a few percentages.
* Reorganize svbvh code so all the traversal functions are in one file
* Don't do test for root so that push_childs can be inlined
* Make shadow a template parameter so it doesn't need to be runtime checked
* Optimization in raytree building, was computing bounding boxes more often
than necessary.
* Leave out logf() factor in SAH, makes tree build quicker with no
noticeable influence on raytracing on performance?
* Set max childs to 4, simplifies traversal code a bit, but also seems
to help slightly in general.
* Store child pointers and child bb just as fixed arrays of size 4 in nodes,
nearly all nodes have this many children, so overall it actually reduces
memory usage a bit and avoids a pointer indirection.
Patch #25901 by Tobias Oelgarte.
Bone transformations would be converted back and forth between different
representations when changing modes, which due to numerical errors could
lead to bone transformations slowly changing as you edit the armature.
Now the editmode head, tail and roll values are stored in bones and used
directly when entering edit mode. Head and tail were already there but
now we ensure they are the exact same value, roll was not yet there, so
we have a version patch for it.
The sub version was incremented to 1 for the version patch.
Using displacement with new bump caused NaN values or crashes.
Since displace code doesn't provide derivatives, it now falls
back to "old bump" by default.
- comparing eulers was ignoring the order.
- printing Euler()'s now prints the order too.
- un-orderable types (all except for Vector's), were not raising an exception when compared with >=, >, <, <=.
each accept Euler/Quaternion/Matrix types.
eg:
Euler.rotate(Quaternion(axis, angle))
Vector.rotate(Euler((pi/2, 0, 0)))
matrix.resize_4x4() and euler.make_compatible() were still returning an instance of themselves, now return None.
1) damping factor is not percentage (it's in frames, who would know that)
2) angles as degrees (cleaning the tooltips for those too)
3) setting Direction to None when changing from Loc and Fh Consts to Ori - negative axis is not supported in Ori Const. Buggy since ever (2.49).
Manually disable jitter usage for anchored and drag dot brush stroke metdhods.
Jitter slider is hidden in UI for this strokes so users can't set it to 0 by hand
and even if this slider would be visible in UI jitter gives wierd result for
this stroke methods.
* Particles that aren't shown are now actually deleted (huge memory savings for flat objects).
* Grid distribution for flat objects is now done on the surface object surface without offset.
* Invert grid option wasn't in ui and it didn't work for non-volume grids.
* New parameter to randomize the grid point locations.
* Resolution soft/hard limits changed to even 50/250.
After discussions with ZanQdo, it was agreed that the current workflow
for making a pose symmetrical was a bit too cumbersome, especially
when auto-keying was enabled, requiring pasting the flipped pose on
another frame so that the changes could be merged back in without
overwriting the "good" half of the rig.
This option for the Paste Pose operator makes things easier, by adding
an option which will make the pose only get pasted on to selected
bones instead of overriding the entire pose. By default this option is
turned off, but can be easily enabled either from the toolbar
(operator properties) or through the F6 popup.
The intended workflow with this option for making a rig symmetrical is
now:
1) Copy pose
2) Select "bad" bones
3) Paste Flipped
4) Enable "On Selected Only" for the operator
If there is sufficient interest, this option can even be enabled by
default. But, we'll see about that later
Scene (Toolsettings, i.e. alongside "layered" option for using NLA
while doing auto-keying)
This option makes all Auto-Keying operations use the active Keying Set
to carry out keyframing operations instead of picking and choosing
their own Keying Sets to use, thus cutting down on the number of
unwanted keys.
Warning: if the older userpref option was enabled in an old
startup.blend, it may be difficult to turn this option off.
mode for case there was no animation at object before enter editmode
- Fixed memory corruption for case of fcurve groups
- Fixed bug with incorrect re-naming "spline[%d].smth" pathes
TODO:
- Also update drivers' curves
- Enable I-key menu and autokeying
Will do this after consultation with Aligorith, shouldn't harm atm.
Render bug in spothalo (weird horizontal line).
Appeared to be precision error... even for doubles,
before doing division a check for FLT_EPSILON works
better than DBL_EPSILON (if there's an alternative).
* Tracing objects with IOR < 1.0 (like air bubbles under water) wasn't working correctly as a refraction was always assumed to be the first thing that happens for transparent materials.
* This fix is ok, but the fact that the internal renderer is not a physically based one is starting to show, as for example blurred reflections in this case are not really possible nicely without some slightly heavier modifications to the ray code.
* Also some cleaned up logic and better comments for my previous total internal reflection commit.
* This was wrong since 2006!
* Raytrace code assumed refractions to go "air -> glass -> air -> glass -> air.." so actually only the first total internal reflection was calculated correctly, but everything after that was wrong.
* Now after a total internal reflection there needs to be an actual refraction before the ray escapes the "glass" object.
Marker selection operators now use a special poll() callback which
checks that there are some markers before trying to run them. This
means that when there are no markers, the full screen range is
available, instead of just those areas above the region masked off for
markers which can be quite slim when trying to save space by only
showing the summary channel.
- use BLI_math functions for removing rotations from objects and pose channels.
- add unit_axis_angle() to avoid setting the Y axis inline anywhere rotation needs removing.
Migrating "redraws" settings from TimeLine view data to per Screen.
The options are now still shown in the TimeLine "Playback" menu
though.
This means that whatever redraw settings you set in a TimeLine editor
will be used throughout a screen (i.e. editor layout) to determine
which editors will get updated during playback, instead of only
certain editors doing certain things at vague times.

Also, I moved some version patches pre 2.56 version bump into a
version-check for 2.56. These must've been missed when doing the
release...
While animating, I realised that actually the 'only selected' and
'include hidden' DopeSheet filtering options are also useful in the
Action Editor, especially while tweaking the animation for some
characters, where you'd like to focus only on some of the character's
control (i.e. eyelid tweaks, hand tweaks, etc.).
The other DopeSheet filtering options aren't so relevant here, so I've
excluded them from this.
Rotation brush used to be crazy because it depends on normal of area
under brush, which is used as axis to rotate vertexes around and
this normal used to change during stroke.
Calculate normal from original mesh state for rotation tool too.
* Only the first object (in scene object order) that instanced a dupligroup was rendered properly, because particle instances were checked for only after creating the render object (and even this check was done wrong).
* Now the actual render object is created only after both object and particle instances have been checked.
This comes in handy for testing importers against 100's of files, quickly showing breakages and easier to setup then unit tests.
Example usage:
blender.bin --background --python source/tests/batch_import.py -- \
--operator="bpy.ops.import_scene.obj" \
--path="/data/testfiles/obj" \
--match="*.obj" \
--start=0 --end=50 \
--save_path="/tmp/test"
Also found my name was spelt wrong in some places :)
calling
bpy.ops.wm.read_factory_settings()
... would clear a scripts namespace if running directly, not in a module.
Fix by backing up and restoring the __main__ module.
Also found BKE_reportf wasnt printing all reports in background mode as BKE_report() was doing.
While doing some animation work over the past few days, I found that
it would be useful to be able to tag keyframes as a another type yet:
"jitter" for fill-in secondary motion (i.e. blinks/hand-keyed camera
shake). Of course, what you really use these for is up to you, but
this is one more option when you need it :)
