Using the new "Add constraint" hotkey (CTRL+ALT+C) or the option in the
pulldown menu, didn't set a proper flag in Curve object when a "Follow
Path" constraint was choosen.
At long last!
This new constraint is pretty simple. Following in the footsteps of such giants as Copy Loc and Copy Rot, it lets you constrain the size of an object/bone to another object/bone, with per axis restrictions.
Added newlines at end of a bunch of files that didn't have them.
removed a couple of unused variables and an extra ';'
(Also removed config.h crap from these files)

1) Target-less IK
If you add an IK constraint without a target set (no object or bone target),
it now can be grabbed and moved with IK, using its own Bone tip or root as
target itself. This way you can use IK for posing, without having the IK
executed while it animates or while a Pose is being solved for real IK.
After grabbing "Target-less IK", it applies the resulted motion in the
pose-channels, which then can be used to insert keypositions.
The Target-less IK bone can still be rotated without IK, also its chain
can be edited as usual.
UI: The CTRL+I menu gives this as an option too. In the 3D window it is
drawn with orangish color.
Note that IK is not resistant to non-uniform scaling yet.
2) Auto-IK
When the option "Automatic IK" is set, in Edit Buttons Armature Panel,
it creates automatic temporal Target-less IK for the Bone you grab or
translate.
The rules are:
- it only works when a single Bone is selected
- if the Bone is a root bone (no parent), it adds IK to the end of the
chain(s)
- otherwise it adds the IK to the active Bone
- the temporal IK chain only consists of connected Bones.
This method is still a bit experimental. Maybe it should become a special
grabbing option (like SHIFT+G in Pose Mode). It also only works OK for rigs
that fit for it well... when a rig already is fully setup with IK it can't
do much good. :)
DAG_object_flush_update() always used scene layers, causing updates to go
wrong with 3d windows with "Lock" off (allowing local layer and camera).
This fixes a larger amount of potential issues.
Also: fixed menu title for adding IK constraint to Bone (CTRL+I).
as well as for Objects. Hotkey: CTRL+ALT+C (bit clumsy I know, but I like
to use the Ckey).
Constraints are added to the active Object or Bone.
Based on selection context, the menu has three versions:
Pose Mode:
- if another bone is selected, bone becomes target
- else if another Object is selected, Object becomes target
- else it adds a new Empty as target
Object Mode
- if another Object is selected: Object becomes target
- else it adds a new Empty as target
Same works this way now for CTRL+I, "Add IK".
To be solved: ALT+C in PoseMode is "Clear Constraints", but in Object Mode
it does "Convert" still...
-> Note; added 2 new c files (split editipo.c). MSVC needs upgrade.
Impatient people can check the goodies in CMS:
http://www.blender3d.org/cms/Action_and_NLA_editor.706.0.html
Most work was on trying to unwind the spaghetti for editing ipos. Too much
history and bad design got added here. Most evident changes:
- made generic 'context' for detecting which Ipo is being edited, or to
assign ipos or to retrieve ipo curves.
- made generic insertkey() for all ipo types, including actions
- shuffled a lot of code around to make things more logical. Also made
sure local functions are not exported
It is far from ready... when action/nla was added in Blender, a lot of
duplicate code was generated. That's for another time.
Now the goodies;
- made Actions to allow any Ipo type
- made NLA to define active actions, for Action window too
- corrected timing for active action, so it shows the 'real time', as
defined in NLA editor.
I did update python code, but that would require testing. Testing is
needed for this commit in general, too many changes happened on all
levels of the animation system. :)
Will keep track of all reports this evening, hopefully it doesnt break
the pre-release schedule!
Minor modifications to simplify the code in evaluate_constraint.
The "Stick" feature will need more work as it gives bad results when skipping frames, jumping around on the timeline and when going backward in time.
Suggestion: Would be nice if it could use the local space too, not just global space planes.
Best is to forget yesterday's commit and old docs. New docs are underway...
Here's how IK works now;
- IK chains can go all the way to the furthest parent Bone. Disregarding
the old option "IK to Parent" and disgregarding whether a Bone has an
offset to its parent (offsets now work for IK, so you can also make
T-bones).
- The old "IK to Parent" option now only does what it should do: it denotes
whether a Bone is directly connected to a Parent Bone, or not.
In the UI and in code this option is now called "Connected".
- You can also define yourself which Bone will become the "Root" for an IK
chain. This can be any Parent of the IK tip (where the IK constraint is).
By default it goes all the way, unless you set a value for the new IK
Constraint Panel option "Chain Lenght".
- "Tree IK" now is detected automatic, when multiple IK Roots are on the
same Bone, and when there's a branched structure.
Multiple IK's on a single chain (no branches) is still executed as usual,
doing the IK's sequentially.
- Note: Branched structures, with _partial_ overlapping IK chains, that don't
share the same Root will possibly disconnect branches.
- When you select a Bone with IK, it now draws a yellow dashed line to its
Root.
- The IK options "Location Weight" and "Rotation Weight" are relative,
in case there's a Tree IK structure. These weights cannot be set to
zero. To animate or disable IK Targets, use the "Influence" slider.
- This new IK is backwards and upwards compatible for Blender files.
Of course, the new features won't show in older Blender binaries! :)
Other changes & notes;
- In PoseMode, the Constraint Panel now also draws in Editing Buttons, next
to the Bones Panel.
- IK Constraint Panel was redesigned... it's still a bit squished
- Buttons "No X DoF" is now called "Lock X". This to follow convention to
name options positive.
- Added Undo push for Make/Clear Parent in Editmode Armature
- Use CTRL+P "Make Parent" on a single selected Bone to make it become
connected (ALT+P had already "Disconnect").
On todo next; Visualizing & review of Bone DoF limits and stiffness
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
Adding Ipos on a Constraint just was working totally insane. Here's how
it works now in the constraint Panel:
- Button "Show" will make the IpoWindow show the Constraint Ipo
(it didn't before, when IpoWindow was not set to correct mode)
- Button "Key" will insert a key point on current frame (and show it in
IpoWindow)
Note that both options will create an Action too, if not existed yet.
So, without opening an IpoWindow you can already animate Constraints.
(Todo: use the auto key option to always insert on changing slider)
And; selecting a Bone will update the Constraint IpoWindow too. Note
however, that when theres multiple Constraint Ipos on a Bone, it only
shows the first... will solve that later.
- PoseMode: Wkey menu, "Flip Left/Right Names". On selected bones, it flips
the L/R tags in names, and calls the proper code to rename everything
that's related (constraint targets, bone-childs, etc).
- PoseMode: Shift+S snapmenu: snap cursor to selected now works
- Outliner: select bones now correctly sets 'active' flag for bones,
updating the UI as well.
Also made sure you cannot select hidden bones in outliner.
- 3DWindow: in PoseMode/EditMode draws name of active Bone too (with user
option "Draw active object name" set.
- Added the new Armature/PoseMode options in View3D pulldowns.
Cleanup:
- moved Pose code from editaction.c to poseobject.c
- removed BSE_editaction.h and BSE_editaction_types.h, moved contents of
it to BIF_editaction.h. One include per C file should be fine. :)
I know the src/ structure would require more elaborated includes, but
we don't have that now...
- PoseMode now is a state Armature Objects can be in. So, while in PoseMode
for an Armature, you can just select another Object or Armature.
- The old PoseMode options (transform, insert keys etc) are accessible
with making the Armature Object 'active' (and have object in PoseMode).
- At this moment no multiple Poses can be transformed/edited at the same
time.
- The old hotkey CTRL+TAB, and view3d header menu, still work to set an
Object's PoseMode
It was quite a lot recode, so tests & reports are welcome.
Oh, as a bonus I added Lasso Select for Bones in PoseMode! It selects using
only the line between root and tip of the Bone.
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-
Read today's meeting minutes for a description.
Bjornmose: We'll need some example and screenshots for the dev pages of blender3d.org. If you can do some, neat, if not, I'll do them.
Matt, Emilie and Chris: Please review UI addition. Pixel alignement and all that fun stuff has not be overly looked for (though I did some cleaning by adding alignment blocks).
Removed a block of a bunch of unused vars...
Added a return NULL to the end of a funtion that is suppose to
return something and could fall through.
editconstraint.c
Added a newline to the end of the file to get rid of a stupid warning.
Kent
Moved get_con_target from editconstraint to constraint kernel file and renamed to get_constraint_target
Make scene.c use constraint functions from kernel instead of doing the switch itself (regrouping specific constraint code in one file).
Add LockTrack as an option in the Make Track menu (Ctrl-T)
Adding fun for vortex forces in 3D window, the representation now match the orientation and direction of the force (this is code will need optimisation). I'll probably be slapped for mixing two things in one commit but some function calls needed to be fixed for the new spelling and since this is really isolated code I didn't feel like wasting time getting a fresh copy, doing the changes and then readded this after commiting.
Fixed some warning regarding implicit casts and constants (this last one is a MSVCism where you need to explicitely tell the compiler to use floats with an f. AFAIK, it doesn't affect/bother other compilers).
Removed a useless commented piece of code in readfile (there was an uncommented copy a couple of lines before)
----------------------------
Another (major) armature speed up for bones with many constraints.
When tranform()-ing, figure out which bones need to be recalculated
beforehand and only update those bones.
--------------------------
Major speed up for armatures during times when you aren't
posing a figure.
Background: the calculation of poses generated by actions and the
calculation of displists were getting somewhat out of sync.
This was being remedied by 'clearing the constraint done flag'
of the pose channels and recalculating the displists every time
the 3d view was redrawn, making life slow and unpleasant.
Commenting out the code that was doing this, then reinserting
the 'clearing the constraint done flag' at the right times
made things a bit more perky.
This is a temporary fix, but a complete fix will require a rewrite of of some part of the where_is_object function, and that would take too much time before 2.31.
This is done by disabling the object position refresh call when calculating these constraints. From the tests I did, this doesn't cause any problem at all.
The main point of this is to create pistons and the like.
For coders:
the detect_constraint_loop function now takes an additional parameter that determines the constraint type of the object it's looping from.
Axis options for TrackTo
LockTrack
FollowPath
Auto creation of TrackTo constraint from Ctrl-T (old track still an option)
Auto creation of FollowPath when parenting to path (Normal parent still an option)
Backward compatibility stuff to convert the per object axis settings to per constraint when a Track constraint is present.
Function to convert old track to constraint (commented out)
Revamped the constraints interface with Matt's work from tuhopuu and the stuff we were discussing earlier.
--------------------
For coders:
unique_constraint_name and *new_constraint_data moved to the kernel (constraint.c)
new Projf function in arithb gives the projection of a vector on another vector
add_new_constraint now takes a constraint type (int) parameter
add_constraint_to_object(bConstraint *con, Object *ob) to link a constraint to an object
add_constraint_to_client(bConstraint *con) to link constraint to current client (object or bone)
add_influence_key_to_constraint (bConstraint *con) to (eventually) add a keyframe to the influence IPO of a constraint
include only (use BIF_interface.h instead)
- split up interface.c in two files: NEW: interface_panel.c
- removed the temporal text files
WARN: FIX AUTOMAKE AND MSVC!
First, check on the new files, which are listed below.
The new butspace.h is a local include, only to be used for the buttons
drawn in the buttonswindow.
- editbuts, animbuts, gamebuts, displaybuts, paintbuts, work now
- i quite completely reorganized it, it's now nicely telling you what
context it is in
- sorting error in panel align fixed (tabs were flipping)
- align works correctly automatic when you click around in Blender
- editsca.c renamed to buttons_logic.h
- button names are truncated from the right for allmost all buttons
(except text buttons and number buttons)
- while dragging panels, you cannot move them outside window anymore
And of course fixed loads of little bugs I encountered while testing
it all. This is a version I really need good test & feedback for.
Next step: restoring material/lamp/texture/world
