levels, child particles, and shadow/SSS/AO quality.. Now also works on what
is displayed in the 3d view instead of only rendering, see panel in the scene
properties.
Most file changes were to make scene available in the isDisabled modifier
callback function.
- particle set weight operator (Shift + K) and from the menu.
- mirror vertex groups operator can also flip weight group names.
a number of utility functions for weight groups added
int *get_defgroup_flip_map(struct Object *ob);
void flip_vertexgroup_name (char *name_r, const char *name, int strip_number); // moved from modifier.c
void copy_defvert (struct MDeformVert *dvert_r, const struct MDeformVert *dvert);
void flip_defvert (struct MDeformVert *dvert, int *flip_map);
Fix#20516: subsurf modiefier+pressing add for smoke sims results in crash.
Fix retopo not working correct on subsurf mesh.
Various deforming modifiers were not correctly taking into account that a
derivedmesh is not necessarily a CDDerivedMesh, made utility functions for
this now.
Mostly the same as the recently added editmode tool with some extras.
* Options to disable filling in the rim between inner and outer surface, since its faster not to detect this in cases where its not needed.
* Option to disable high quality normal calculation, mostly noticable when operating on building walls, not needed for cloth or more organic shapes.
* Option to disable 'even thickness', again, not needed in some cases.
Also options for creasing inner/outer and rim edges, need this for makign Sintels cloths solid since zero crease looks far too soft.
note:
* UVs and VCols etc are copied to the new skin however rim faces dont get the UVs or vcols set from the faces they are created from yet.
* Normals are assumed to be pointing outwards
* used patch from Uncle Entity as a template since it added the DNA and RNA entries but the actual modifier from the patch wasnt used.
* Now support a Surface mode next to the existing Volume mode. This binds
the mesh to the cage mesh surface rather than it's volume.
* Implemented reusing the bone heat weighting code.
* Advantage is that it works for cage meshes that are not volumes and that
binding is much faster.
* Weak point is that disconnected components of a mesh are not guaranteed
to stick together (same problem exists with bone heat weighting).
* Bind weights could still be compressed better to use less memory.
Example file:

* Displacement coordinates are now stored differently, as a grid per
face corner. This means there is duplication of coordinates, especially
at low subdivision levels, but the simpler implementation justifies it
I think.
* ToDo: conversion of existing multires files (2.4x or 2.5x), loading them
may even crash now.
* Editmode preservation/interpolation code also has not been updated yet.
* Multires now works on the CCGDerivedMesh grids instead of CDDerivedMesh,
which should be more memory efficient.
* There are still bad memory peaks (if you're using 32bit) when subdividing
or propagating displacements. Though at least there should be no huge
memory blocks allocated, which windows is now to have trouble with.
* Still found some weird spike artifacts at lower multires levels, some also
happening before this commit. Perhaps computation of tangents needs to be
tweaked more.
* Multires modifier now has viewport, sculpt and render levels. Also the
levels have been made consistent with subsurf, previously the same level
of subdivision was one less for multires.
* Both multires and subsurf modifier now can have their subdivision level
set to 0 for no subdivision.
Rather than applying the modifier to the object data, it will create a new shape
with the deformed vertices in there. Only mesh at the moment, other object
types on the todo.
* structural can be set to 0
* pre-roll now available through GUI and works like following:
a) Pre rolled frames are NOT cached
b) reset cache + cloth on pre roll setting change
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:

Blended shape keys can now be displayed & edited in edit mode. This
is much like showing an armature modifier in edit mode, and shape keys
now are a applied as a virtual modifier (for mesh & lattice only, curve
doesn't fit in the stack well due to tilt).
The main thing missing still is being able to switch between the active
shape key in edit mode, that's more complicated.. but the weights of
other shapes can be edited while in edit mode.
One thing to be careful about is that this does automatic crazyspace
correction, which means that if you edit a shape key with a low value,
the actual vertices will be moved to correct for that and actually move
a (potentially much) longer distance.
Also includes some UI tweaks, mainly placing some buttons horizontally
since the vertical list was getting too long.
Also:
* UI now takes ID self check flag into account so that e.g. it
doesn't offer to the make object it's own parent.
* Mesh loop cuts number of cuts had wrong limits.
* Don't use mesh_get_derived_final in modifier stack, but
ob->derivedFinal instead. Avoids crashes on dependency loops,
and in case there is no loop it should have been created.
* #19583: Keying Sets list issues
Deleting a Keying Set (or a Keying Set Path) set the active index to 0, but that would mean that the first item would be selected but not visible.
* #19590: Keyframing properties of a modifier with more than one of it's type the property will highlight in all
- Modifiers now always have a unique name, so renaming a modifier should check that the name is unique. Most of the files changed in this commit were just to make sure that modifiers got unique names when they were created
- Modifiers path getter was wrapped a bit wrong (missing the "s around the name)
* Constraints Bugs
- Constraints renaming now also makes sure the names stay unique
- Fixed (or attempted to fix) compiler warnings about some enum declaration for distance constraint
The goodies:
* Curves can be used as normal dynamic effectors too with
the new "curve" field shape.
* Group visualization has optional duplication counts for
each object in the specified group.
* Object & group visualizations, which are done without
taking the dupliobject's global position into account
(unless the whole group is used). This is much nicer than
the previous behavior, but I added a "Use Global Location"
option for those who want to use it the old way.
* The active particle system's particles are now drawn a
with theme coloured outline instead of pure white.
* Added object aligned velocity factors (buttons categorized
and re-organized too).
Bug fixes:
* Absorption didn't work as the ui toggle button was forgotten.
* Some other force field ui tweaks.
* Crash after adding children and changing trails count.
* Display types "cross" and "axis" crashed.
* Particles weren't drawn with correct coloring.
* Billboards didn't update properly in viewport to camera
location changes.
* Particle rotation wasn't recreated correctly from point cache.
* Changing particles amount crashed sometimes.
* Some files with child hair crashed on loading.
* Compiler warning fixes.
* Adding boids crashed on frame 1;
* Unified scene wide gravity (currently in scene buttons)
instead of each simulation having it's own gravity.
* Weight parameters for all effectors and an effector group
setting.
* Every effector can use noise.
* Most effectors have "shapes" point, plane, surface, every point.
- "Point" is most like the old effectors and uses the
effector location as the effector point.
- "Plane" uses the closest point on effectors local xy-plane
as the effector point.
- "Surface" uses the closest point on an effector object's
surface as the effector point.
- "Every Point" uses every point in a mesh effector object
as an effector point.
- The falloff is calculated from this point, so for example
with "surface" shape and "use only negative z axis" it's
possible to apply force only "inside" the effector object.
* Spherical effector is now renamed as "force" as it's no longer
just spherical.
* New effector parameter "flow", which makes the effector act as
surrounding air velocity, so the resulting force is
proportional to the velocity difference of the point and "air
velocity". For example a wind field with flow=1.0 results in
proper non-accelerating wind.
* New effector fields "turbulence", which creates nice random
flow paths, and "drag", which slows the points down.
* Much improved vortex field.
* Effectors can now effect particle rotation as well as location.
* Use full, or only positive/negative z-axis to apply force
(note. the z-axis is the surface normal in the case of
effector shape "surface")
* New "force field" submenu in add menu, which adds an empty
with the chosen effector (curve object for corve guides).
* Other dynamics should be quite easy to add to the effector
system too if wanted.
* "Unified" doesn't mean that force fields give the exact same results for
particles, softbody & cloth, since their final effect depends on many external
factors, like for example the surface area of the effected faces.
Code changes
* Subversion bump for correct handling of global gravity.
* Separate ui py file for common dynamics stuff.
* Particle settings updating is flushed with it's id through
DAG_id_flush_update(..).
Known issues
* Curve guides don't yet have all ui buttons in place, but they
should work none the less.
* Hair dynamics don't yet respect force fields.
Other changes
* Particle emission defaults now to frames 1-200 with life of 50
frames to fill the whole default timeline.
* Many particles drawing related crashes fixed.
* Sometimes particles didn't update on first frame properly.
* Hair with object/group visualization didn't work properly.
* Memory leaks with PointCacheID lists (Genscher, remember to
free pidlists after use :).
New stuff
- Bending springs for hair dynamics.
Code cleanup & optimization
- Disabled reactor particles temporarily for cleanup, it's a clumsy system that will be replaced with something better.
- Removed child seams, something better will come here too :)
- Normal particle drawing data is now saved between redraws if the particles don't move between redraws.
* For example rotating the 3d view is now realtime even with 1M particles.
- Many random values for particles now come from a lookup table making things much faster.
- Most accessed small point cache functions are now much faster as macros.
- Lot's of general code cleanup.
- Nothing big should have changed so if something doesn't work like it used to it's probably just a typo somewhere :)
Note sure what to do with this one, and personally think
we should avoid using macros for this kind of thing:
V_GROW(edges);
source/blender/editors/mesh/loopcut.c:232: warning: value computed is not used
- Some big refresh issues with softbody & cloth point cache usage should now be fixed.
- Removed sticky objects from particles (better stuff will come back when I get to updating reactor particles).
- Some initial easy memory efficiency cleanup for ParticleData struct. The ultimate goal is to get particles less memory hungry -> more particles possible in single scene.
- Wrong path timing clamping caused hair particles to seem disappeared when changing between normal<->hair particles.
- "Calculate to current frame" in cache buttons baked instead of the intended function.
- Boids particle data is now a bit better organized.
The 'Show Sliders' option for DopeSheet and Graph Editors now works again. When this option is enabled (it is disabled by default), a slider (or combobox) is shown beside the mute/lock toggles for F-Curves. Editing the slider will result in a new keyframe being added on the current frame.
So, for all the (ex)-Maya animators out there, you can now animate in a channelbox-like way. :)
Also in this commit:
* Fixed some warnings in modifier.c from previous commits there
* Fixed some refresh problems with DopeSheet channel list (which were only obvious after adding back the sliders)
* Removed the old/unrestored and nasty slider code used in the past by the Action Editor only.
Fixed some typos made in previous commit. Hook Modifier should now work correctly again (and also for newly added Hook relationships)
Notes:
* To add a hook, you currently need to perform the following steps
1) add modifier from menu (no operator in EditMode)
2) specify the object (and/or bone to use as the hook target)
3a) in EditMode, select the vertices you wish to be affected by the hook, and press 'Assign'
3b) alternatively, fill in the vertex-group field for the Vertex Group which contains the vertices to be affected
4) press 'Reset' (to make sure hook will behave correctly)
5) optionally, also press 'Recenter' if the hook position isn't right...
* BUG ALERT (Brecht/Ton): it is impossible to clear the vertexgroup/bone fields once you have assigned some value. Doing backspace+enter (or any other variation) will always result in the first item in the search menu being used.
Made Hook Modifier be able to use bone targets. However, I haven't been able to verify that everything will work perfectly, since just creating a new Hook Modifier and assigning targets doesn't set hmd->indexar correctly.
* Popup menus now remember the last clicked item again.
* Modifier and File Format menus are now organized in multiple
columns with categories.
* Hook, explode, uv project modifiers have all their buttons
again with the relevant operators implemented.
* Modifiers that can't be added by the user, or don't work on
curves for example, are not in the menu anymore.
* Fix search menu overlapping buttons when near the bottom of
the screen.
* Fix uv layers search menu not working in some modifiers.
* Cleanup popup menu code a bit, layout engine is used in more
cases now instead of ugly position calculation code.
