- Bugfix #25937
Child-of constraint now behaves like regular parent-child
relationship when all options are set. This prevents the
errors that can happen when decomposing non-uniform matrices.
- Todo item
The area corner hotspots for splitting/merging were far too
narrow. Now it uses a circular distance to detect whether
the hotspot is active. Also cleaned up drawing code for it.
* After countless different bugs particles should now render correctly inside dupligroups.
* Only particles with metaball visualization are still problematic, this is mostly due to the ancient metaball code.
* I'll also add a test file for some of the situations, so that hopefully these cases stay fixed :)
- 'axis' arg was not coerced from a tuple like other args now do.
- 'axis' arg was being modified in-place (VERY BAD).
- also made new function matrix_3x3_as_4x4().
3D View:
In quad-view mode, the options to set back/bottom/left views were
blocked. Now they work again.
Note: the oparator polls don't have a check for properties... so it
cannot be finegrained here. Checks are inside code.
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.
reported by Micael Dias (and many others, see duplicates list)
On closing the first ("main") Blender window the very first OpenGL context
got deleted too. This context needs to be retained, since we share quite a
bit of OpenGL data through it to the newly created contexts (new windows).
Thanks to Ton Roosendaal for thinking out loud while trying to figure out
what the actual cause was.
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.
* [#25638] 'Insufficient thread locking' for sounds
- Actually a workaround for an msvc bug, msvc STL containers are buggy
* [#25922] Sound does not play in BlenderPlayer(r34579)
- Windows OpenAL doesn't seem to have clear context error state on initialising
Running 'make' starts an out of source build with CMake in ../build/OS_CPU, creating the dir and configuring CMake if necessary.
So casual users can just run this without changing dirs:
'svn up ; make'
* 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.
