====================
The MeshDeform modifier can deform a mesh with another 'cage' mesh.
It is similar to a lattice modifier, but instead of being restricted
to the regular grid layout of a lattice, the cage mesh can be modeled
to fit the mesh better.

Implementation Notes:
- OpenNL has been refactored a bit to allow least squares matrices to
be built without passing the matrix row by row, but instead with
random access. MDef doesn't need this actually, but it's using this
version of OpenNL so I'm just committing it now.
- Mean value weights for polygons have been added to arithb.c, a type
of barycentric coordinates for polygons with >= 3 vertices. This
might be useful for other parts of blender too.
"Rotation Difference"
This option, for Bones, allows the angle between two Bones to be
the driver for another Ipo channel. This angle now is hardcoded
based on the Bone-space orientation (without parenting rotation).
Thanks to nathan for poking and test!
New listbase functions:
void BLI_insertlinkafter(struct ListBase *listbase, void *vprevlink, void *vnewlink);
- corrolary to insertlinkbefore
BLI_sortlist(struct ListBase *listbase, int (*cmp)(void *, void *));
- simple in place sorting method. NOT optimized, so use for small lists only. Uses a variant of insertion sort (I was lazy, people should feel free to rewrite).
====================
This changes the way hinge bones are transformed when their parent bones
are also selected. Before it just disabled transform for these, now they
are rotated and scaled as well, but without influencing the transform
center, which gives behaviour as if they were regular bones.
==
Solving is now done independent of scale, by scaling the chain to have a
size of about 1.0. This solves some issues with small or big chains, and
also makes the IK stretch setting independent of scale. The latter breaks
backwards compatibility somewhat, but is an improvement over what it did
before.
When scaling all the control-points in the IPO Editor with negative scales, the control-points would end up "sticking together", and cancelling/undo would not help.
When using targetless-ik, the offset in rotation of the final transform from the rest-position was being incorrectly calculated.
Now, visual-rotation keyframing uses the space-switching code I wrote for constraints, to calculate the value to keyframe. So far, it seems to work quite well.
As the constraint space-switcher correctly handles hinged bones too (I think it should!), I've also removed the restriction of only allowing visual-rotation keying on bones that didn't have hinge set.
This changes the default behaviour in adding new objects, which has been
discussed for a long time, in person, on the funboard, and in the tracker,
and was agreed to be implemented during the 2.5 release cycle, so here it is.
They have been made default, with preferences to bring back old behaviour since
although people like myself still prefer the new default anyway, it will benefit
new users the most.
The preferences are in the 'Edit Methods' section, changing back to old behaviour
is as simple as a click of a button.
- Switch to edit mode preference
By default, now adding a new object doesn't automatically switch to edit mode.
Not only can this be annoying (most of the time when setting up scenes and models
I don't want to edit it straight away anyway), but it's a major hurdle in the learning
curve that new users have had to deal with at a very early stage.
Blender's different modes are an important part of understanding how the software works
and should have clear behaviour. The problem is that when a user selects something from
the add menu, he's not telling Blender to change modes, he wants to add an object.
But Blender then goes ahead and changes modes underneath him anyway, something that was
never explicitly asked for, something that's unrelated to the mental task at hand, and
fundamentally important to the operation of the software.
We observed plenty of people struggling with this during the training sessions that
we ran during Project Orange, and there's also no shortage of "why can't I select
other objects" questions on the forums.
- Aligned to View preference
Now by default, adding a new object doesn't rotate it so it's aligned facing the view,
but rather, it's remains unrotated in world space. This is something that's more of
a convenience issue (allowing people like me to stop the 'Add->Tab->Alt R dance),
but also makes things easier for new users, especially when doing things like rigging.
For a lot of tools in Blender, like curve deform, path cycling, constraints, it's necessary
for your objects' local axes to be aligned. This requirement isn't that obvious, and I've
had to debug rigs a few times from the animator in our studio, who has everything set up
correctly, but he just happened to be in a different vie at the time he added the object,
so they're misaligned and causing problems. Having all objects get created aligned to
worldspace, by default, makes a lot of these problems go away. It's much more understandable
when rotations are caused by something you've done explicitly, rather than as a side effect
of the software.
For convenience as well, most of the time, when I'm working in context and I decide I need a new object,
particularly working on production scenes that involve more than just one model, an Alt R
is almost always required after adding, since I don't want to have to disrupt the current
view of the scene by switching to top view, just to add an object. It's a bit arbitrary,
the view from which you want to look at your objects isn't usually the way you want them to
be looking at you.
Now the Copy Scale Constraint also has the Offset functionality that Copy Loc/Rot have.
== Copy Rotation Constraint ==
Also, fixed the tooltip for the CopyRot Offset button.
Note: when working with pose-bones, and using offset, setting both owner+target spaces to pose-space should cancel any unwanted rotations visible.
Copy Rotation constraint now has ability for the owner's rotation to be added on top of the copied rotation (i.e. an 'offset' like for the Copy Location constraint).
This commit adds a new node, crop, to the compositor. This node can be used to
crop input image. It has two modes of operation. It can either crop image
size (Crop Image Size option) or crop while retaining original size of the
image. This latter mode can be used to preview the crop.
Use X1, Y1, X2, Y2 controls to manage the area to be cropped.
Note that I added a check for image preview min and max values to node_update.
This is because it could give inappropriate values in certain cases when
Crop Image Size option was toggled (values such as x1=0, y1=0, x2=60, y2=0 would
result in eternal loop due to bad min and max (min bigger than max!)). The check
makes sure that min and max values are always valid.
Commit I did in March (10378) tried to fix typedef callback for Group
nodes, but it missed a case, causing group node display to be wrong on
load (only first drawing was wrong).
Version patch for Constraints Refactor I was getting called for too many cases. This was noticeable in the way the StretchTo constraint got reset on loading.
This was caused by an error I made when converting old code during the constraints recode 2. As a result, constraint subtargets got cleared, messing up proxies.
(set_constraint_target didn't use to clear the subtarget of a constraint when passed NULL for the subtarget argument)
* added support for .dds image files
* added support for .int, .inta and .rgba image files
== MSVC 7.1 project files ==
* added WITH_DDS to support .dds files when compiling with the project files by default
* added the dds source files to imbuf project
* also added CMP_glare, CMP_lensdist, CMP_tonemap nodes to nodes.vcproj
layerMask access for pose bones, even though this is a Bone property, its much more convenient to add access from the poseBone, it also matches how the
user interface works.
----------
Document Peter's fps_base attribute for scene rendering objects; also remove
framesPerSecBase() method (preference is to add only attributes, and he did
add fps_base attribute).
Curve select lasso and border didnt work with hide handles enabled.
Hiding handles was using the scene->selectmode variable, but looking at this now, I see there are places where selectmode is compared with
SCE_SELECT_VERTEX, EDGE, FACE etc. as well as being.
Better to use a global flag, same as G_DRAWFACES.
This is not good since anyone using this in the few days will have an invalid selectmode variable. simple way to fix is to change modes, so do_versions shouldnt be needed.
* when setting the face, images with alpha's will set the texface's alpha option.
* added a draw even to redraw view3d and uv/image view - so the Draw Faces button redraws properly.
* made a macro for checking if the object will draw with textures
* textured meshes in editmode only draw a selected face overlay (otherwise the entire mesh would get a plue tint wich isnt
nice for viewing textures), the selected highlight is still there, this is how Face/UV mode looked.
* Alpha clipping STILL had a case where it wasnt disabled and the interface had its alpha clipped, this should be fixed now.
added an option to reload selected strip data (Alt+R - same as reloading images in the imaeg
viewer)
made the sequencer max memory limit 16gig for 64bit's.
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):
