Full logs for changes will be added later. Worth to note now;
- support for 'tree IK' added
- DOF and stiffness per IK bone (in pose only)
- Orientation IK support (target rotates -> chain follows)
This is still WIP. Buttons might change, button ranges will change, and the
way 'IK groups' are working will change. You can play with this, but don't
expect saved files to work still by end of this day! :)
Main target was cleanup of editconstraint.c and removal of the ugly
ob->activecon (active constraint channel), which was set by the "Show"
button in the Constraint Panel.
Better is to introduce an 'Active Constraint' itself, which stores in
the Constraint itself. By using this setting, and by checking the active
Bone, the UI can update reliably now. This only shows now in IpoWindow
btw (for constraint ipos). The active Constraint is drawn in the Buttons
with a slightly brighter backdrop. Any action in that Panel selects a
constraint now (even click in backdrop).
So now we have pose channels & constraint channels nicely behaving. Now the
darn Action channels... :)
Further in this commit:
- interface.c: Button ROUNDBOX now does button callback too.
Button NUMSLI didn't do the callback on a click only
- Cleaned up include files in yafray, got annoyed it compiled over all the
time.
- removed unused variables from Constraint struct
- removed {lattice,curve}_modifier functions
- changed render code to use displist for curve rendering
instead of making its own. required adding a bevelSplitFlag
field to DispList. I also fixed the bevel face splitting
which did not work correctly in many situations.
- changed so all curve data creation happens in makeDispListCurveTypes,
includes making bevel list and filling polys
- changed render code to use displist for surface rendering
- removed Curve.orco variable, built as needed now
- removed stupid BLI_setScanFill* functions... why use a function
argument when you can use a global and two functions! Why indeed.
(this fixed crash when reloading a file with filled curves and
toggling editmode)
- bug fix, setting curve width!=1 disabled simple bevel for no
apparent reason
- cleaned up lots and lots of curve/displist code (fun example:
"if(dl->type==DL_INDEX3 || dl->type==DL_INDEX3)"). Hmmm!
- switched almost all lattice calls to go through lattice_deform_verts,
only exception left is particles
- added DBG_show_shared_render_faces function in render, just
helps to visualize which verts are shared while testing (no
user interface).
- renamed some curve bevel buttons and rewrote tooltips to be
more obvious
- made CU_FAST work without dupfontbase hack
Also by the way I wrote down some notes on how curve code
works, nothing spiffy but it is at:
http://wiki.blender.org/bin/view.pl/Blenderdev/CurveNotes
He even made a nice doc in wiki:
http://wiki.blender.org/bin/view.pl/Blenderdev/Blendgz
Usage: set the option "Compress File" in the main "File" pulldown menu.
This setting is a user-def, meaning it is not changed on reading files.
If you want it default, save it with CTRL+U.
The longest debate went over the file naming convention. Shaul started
with .blend.gz files, which gave issues in Blender because of the code
hanging out everywhere that detects blender files, and that appends the
.blend extension if needed.
Daniel Dunbar proposed to just save it as .blend, and not bother users
with such details. This is indeed the most elegant solution, with as
only drawback that old Blender executables cannot read it.
This drawback isn't very relevant at the moment, since we're heading
towards a release that isn't upward compatible anyway... the recode
going on on Meshes, Modfiers, Armatures, Poses, Actions, NLA already
have upward compatibility issues.
We might check - during the next month(s) - on a builtin system to
warn users in the future when we change things that make a file risky
to read in an older release.
- With Actions on a Pose, ESC in transform restored wrong.
This is solved similar to ipos now, storing a 'last time evaluated'.
Could be extended to ghosting... soon.
- Moving the little yellow 'key blocks' in Action window didn't update
3d window. ALso the 'lock' option didn't work, and flashed header.
- Pose Transform: noticed there were still errors in cases, especially
with actions. Painfully tried to build the desired matrix now.
- Removed obsolete Bone pointer from TransData
- cleaned up 'version correction' a bit. There was code slowing down
current files even (armatures were evaluated all, even when not in
current layer, was added to make sure they get converted OK).
Send me old files that crash now! :)
- on reading older files with path-constraints, a fix had to be added.
- error "badd call to addqueue' found when using header-less window for
filewindow
- In Solid drawmode, bones get drawn solid too now. Including Outline-
selection color, if that's set.
Disable it by setting Object-buttons "drawtype" for the Armature.
Color used for solid bones is in Theme editor.
- EditMode armature now follows (Mesh edit) theme colors (Vertex, Edge)
- PoseMode armature has ThemeColor for selection, and draws three extra
colors now;
- blue shade for bones with action Ipos
- yellow for bones with IK
- green for bones with a constraint
- "X ray" now only works for PoseMode... needs review, can be done better
- "Draw Names" option uses theme color too, also indicates selection.
Fixes;
- In Armature EditMode, the deformed Mesh goes to rest-position
- Border select didn't clear 'active' flag in Bones in PoseMode
- Mouse-click select didn't work when a dashed line was close to Bone
a single object, but was still called outside of that scope. Caused crashes
for example when editing Ipo curves of action keys.
editaction.c and editnla.c still need to be tackled...
Ipocurves with "Auto" handles now have option to remain horizontal on the
extrema (tops & valleys). Use ALT+H to set this per selected curve.
Note this is a per-curve feature, not per-handle.
If it works satisfying I can check on making this the default new added
curve.
- IK constraint now uses Ipo from action again
- Bug in last commit; the object action was ignored... did NLA always
Editmesh:
- when there are edges in mesh, it now only copies selection in edges
when you have selectmode edge
weird disabled code that was hanging out there for ages.
Also cleaned up NLA blending itself, it was copying far too much data
around. Should be three times faster or so... need good test!
And restored Action Baking.
Aim was to get a total refresh of the animation system. This
is needed because;
- we need to upgrade it with 21st century features
- current code is spaghetti/hack combo, and hides good design
- it should become lag-free with using dependency graphs
A full log, with complete code API/structure/design explanation
will follow, that's a load of work... so here below the list with
hot changes;
- The entire object update system (matrices, geometry) is now
centralized. Calls to where_is_object and makeDispList are
forbidden, instead we tag objects 'changed' and let the
depgraph code sort it out
- Removed all old "Ika" code
- Depgraph is aware of all relationships, including meta balls,
constraints, bevelcurve, and so on.
- Made depgraph aware of relation types and layers, to do smart
flushing of 'changed' events. Nothing gets calculated too often!
- Transform uses depgraph to detect changes
- On frame-advance, depgraph flushes animated changes
Armatures;
Almost all armature related code has been fully built from scratch.
It now reveils the original design much better, with a very clean
implementation, lag free without even calculating each Bone more than
once. Result is quite a speedup yes!
Important to note is;
1) Armature is data containing the 'rest position'
2) Pose is the changes of rest position, and always on object level.
That way more Objects can use same Pose. Also constraints are in Pose
3) Actions only contain the Ipos to change values in Poses.
- Bones draw unrotated now
- Drawing bones speedup enormously (10-20 times)
- Bone selecting in EditMode, selection state is saved for PoseMode,
and vice-versa
- Undo in editmode
- Bone renaming does vertexgroups, constraints, posechannels, actions,
for all users of Armature in entire file
- Added Bone renaming in NKey panel
- Nkey PoseMode shows eulers now
- EditMode and PoseMode now have 'active' bone too (last clicked)
- Parenting in EditMode' CTRL+P, ALT+P, with nice options!
- Pose is added in Outliner now, with showing that constraints are in
the Pose, not Armature
- Disconnected IK solving from constraints. It's a separate phase now,
on top of the full Pose calculations
- Pose itself has a dependency graph too, so evaluation order is lag free.
TODO NOW;
- Rotating in Posemode has incorrect inverse transform (Martin will fix)
- Python Bone/Armature/Pose API disabled... needs full recode too
(wait for my doc!)
- Game engine will need upgrade too
- Depgraph code needs revision, cleanup, can be much faster!
(But, compliments for Jean-Luc, it works like a charm!)
- IK changed, it now doesnt use previous position to advance to next
position anymore. That system looks nice (no flips) but is not well
suited for NLA and background render.
TODO LATER;
We now can do loadsa new nifty features as well; like:
- Kill PoseMode (can be option for armatures itself)
- Make B-Bones (Bezier, Bspline, like for spines)
- Move all silly button level edit to 3d window (like CTRL+I = add
IK)
- Much better & informative drawing
- Fix action/nla editors
- Put all ipos in Actions (object, mesh key, lamp color)
- Add hooks
- Null bones
- Much more advanced constraints...
Bugfixes;
- OGL render (view3d header) had wrong first frame on anim render
- Ipo 'recording' mode had wrong playback speed
- Vertex-key mode now sticks to show 'active key', until frame change
-Ton-
(Looks like big commit, but is mostly just change of API call!)
Particle emittors now can be parented to an armature Bone, and give the
correct path for each particle. Note that this doesn't work for deform!
And, for each particle the entire armature is evaluated, all actions and
NLA strips.
It used to work a little while BTW, but the code just called ALL armatures
and made ALL deforms again. Was quite slow... thats why the API call
change: do_all_actions() now accepts Object * to only do that one. With
a NULL it now does all still. Will disapppear in recode of course...
Lattices seem to have deform lag, when they're animated with Ipos.
Found out this behaviour is already from before 2.25... solved with
removing a where_is_object() from deform code, but dont fully grasp
why.
Tested with good demo file, with motion blur too.
2) No functional changes, just made 2 files compile without warnings;
- added extra ifdefs __NLA_BLENDCON for unused calls
- removed zealot 'const' from function protos and variables, these cannot
work there, and hence gave warnings
- added void pointer casts for array conversions in matrix code
This was caused by a very primitive method of interpolating quaternions.
It was converting quats to mat and back to quat, and then just doing
a linear interpolation. That whilst quaternions are renowned for having
good interpolation possible.
I've experimented with 2 quaternion interpolation methods, and can only
get one to work correctly... the "official" version from Watt brothers
I can't get working, both are in arithb.c now.
Will arrange *close* review with experienced NLAers for it! But testing
here gives fully predictable results.
Also changed;
- added pointer check in drawaction
- changed puldown menu for correct hotkeys for move NLA strips up/down
in readfile.c I renamed some localvars that were named main to mainl in
a couple of functions.
in action.c I initalized a var to 0. This is probably not needed but
its a little safer incase someone adds more modes...
I've included a diff of this last one below.
