This is a new incarnation of compatible_eul(), a function called:
void Mat3ToCompatibleEul(float mat[][3], float *eul, float *oldrot)
It uses the two euler extraction methods as added by Brecht a while ago,
and checks for compatibility each, and then picks the best of the two
based on minimal difference with 'oldrot'.
Gives for rotation key inserting a much higher hitrate for OK eulers.
This is a much faster and easier way to give a bevelled curve a taper, without
using taper curves. Each point on a curve now has a 'radius' value that you can
shrink and fatten using Alt S, which will influence the taper when the curve is
bevelled (either with a bevob, or with front/back turned off and a bevel dept
set). Alt S shrinks and fattens the selected points in an interactive transform,
and you can set an absolute radius for selected points with 'Set Radius' in the
curve specials menu.
See demo: http://mke3.net/blender/etc/curve_shrinkfatten-h264.mov
This can be a quick way to create revolved surfaces (eg.
http://mke3.net/blender/etc/wineglass-h264.mov ) and it would be very
interesting to use this radius value in other tools, such as a 'freehand curve'
tool that would let you draw a curve freehand, with the radius affected by pen
pressure, or even using the radius at each point to control curve guides for
particles more precisely, rather than the continous maxdist.
- pending commit for OSX intel systems, with intel graphics. These now call
an extra swapbuffers after glFlush(). Code is ifdeffed, and doesnt affect
other systems.
- show-off commit: option to have transparent nodes over the composite
result. Only draws Image for active Viewer Node now, and image doesnt
translate nor zoom (which isnt bad though).
Set in themes the alpha color of "node backdrop" to make nodes
transparent.
Nkey "Properties Panel" now has Dimension ("Dim") buttons too.
This reads from the actual bounding box value to see the size. Note that
dimensions for animated & deformed objects will change per frame.
(Cleaned up buttons layout for patch, and added support for Curve, Text and
Surface objects)
Old annoyance in Blender; zooming in very far makes scaling/rotate
around invisible pivot going bezerk. The easy fix was just enforcing
floats in integer math.
Bug #3657
Texture Space transform
* grab/size: did not support local constraints properly
* size: constraint support did not respect object orientation
Based on a patch by Matthias Derer, this adds the distance moved to a translation (grab) transform
(both 3D and 2D, although the 2D transform displays the normalised distance only).
only in Face-Select mode. It then uses for rotate and scaling the face
center itself as reference.
Code uses a loop-in-loop to find the face that belongs to the vertex...
means it will be slow with operations on 10k or more faces. Acceptable
for now, will make it nicer later. :)
- I changed the input method for shear quite a bit. It used to be constant
regardless of zooming, so it was quite limiting in the amount of shear you
could do. However, I'm not sure if the current method is quite well
adjusted, if you think it works too fast, please drop me a line.
It's basicly the same method as Shrink-Fatten / Push-Pull except on an
horizontal basis. (since shear is an horizontal motion and the two others
are more like pulling towards/pushing away from you in regards to the center)
- Factored out the input methods in preparation for later code <evil>.
Using the MMB constraint chooser in Transform, accidentally printed the
setting from the orientation menu (Local, View, Normal).
Martin: not sure if this a solid fix... the print now looks fine, but the
code isn't nicer this way. :) (just a one liner change though!).
When using 'protection flags' for XYZ rotations, inserting keys in
Poses resulted in wrong interpolations (doing -270 degrees instead of
+90 for example). This caused by converting quaternion to euler and
back...
Solved it by correcting the quaternion in the end for the rotation
sign of the original quaternion.
NOTE: Pose animators should be aware that inserting rotations keys of
180 degrees or larger will still make the key rotate along the shortest
path.
While using automatic IK, a pending redraw event could draw the buttons
window again, reveiling the temporal IK buttons. Using them, after grab,
caused a crash.
Also: noticed that the undo push for transform is called too early, so it
saves the state before 'special_after_trans' was called.
Also: in editmode armature, changed shift+A "Bones" in "Bone".
You now can set, in NKEY Transform Properties Panel, per XYZ rot/loc/size,
a protection for Transform tools to not change these values anymore.
This now works for Objects or for Bones in PoseMode.
Usage is especially for character animation, to give Bones in a Pose
defaults for rotation axes, so you don't have to worry about the correct
limitations (or setup complex IK limits).
Of course, this feature doesn't influence the animation system.
As an extra also the Transform Widgets then draw less handles. Note this
is based on the actual locked value, and depends still on Manipulator
orientation whether it can be used really.
Implementation warning: I had to remove the 'return' in the middle of the
editobject.c compatible_eul() call. It now makes nice compatible eulers
when they're simple (single axis rotations). Unfortunately there was no
note in the code why it was ever removed...
ALso: fix for crash in using Crease Transform and Mirror modifier.
MMB uses global axis, Ctrl-MMB uses user defined. (Alt-MMB cause conflict with the window manager on linux)
(for hotkeys, first press is global, second press is user defined)
- Trackball rotate was missing the NoConstraints flag
- Zooming didn't recalculate the 2D center correctly
- Zooming in transform was sending event to the 3D window even when working on UVs. (disabled when working on UVs for now, will need to send events to a 2D window handler eventually)
- In camera mode, when the selection was exactly on the camera, initgrabz was barfing, fallback to 1.0 now, which gives ok results.
Press ALT+B in 3d window, draw a rect, and it becomes a clipping
volume of 4 planes. You then can rotate the view anyway you like.
Works for each 3d window individually.
Disable it with another ALT+B press.
Commit is huge because it had to change all selection code as well.
The user-clipping planes are in 'eye space', the other clipping
happens in projected 'viewport space'.
Nice to notice is that the 'x=3200' convention (to denote a coordinate
is clipped) now is a define. Define value is still a number though... but
we now can get up to screens of 12000 pixels without issues!
Known issue; here it refuses to draw the 'object centers' or Lamp icons
within the clipping region. Can't find any reason for it... however, we
might move to non-pixmaps for it anyway.
Testing might reveil numerous issues, will be standby for it.
Curious? Check this http://www.blender.org/bf/rt4.jpg
For defining the deformation distances of Bones, three values are being
used now. The bone tip and root radius define the bone-shape itself and the
"dist" defines the soft area around it. A full (user) doc is in CMS here;
http://www.blender3d.org/cms/Armature_Envelopes.647.0.html
Note: todo still is allowing both Vertex Deform Groups and these Envelopes
together (and or per Bone).
Also part of this commit is:
- New: Hiding bones in EditMode. This is a separate 'hide flag', so you can
keep the PoseMode hidden Bones separate from EditMode.
(In the future we should do some kind of bone-grouping or so)
- While transform(), the hotkeys G,R,S only switch mode when the previous
mode was compatible. Caused conflicts with Crease/BoneDist/etc.
- Deleting the last VertexGroup now also deletes the entire Mesh 'dvert'
data. Sounds logical, but remember that VertexGroups are partial on a
Mesh, partial on Object. Weird design decision though...
Anyhoo, at this moment the only way to have Bone Envelopes deform, is
by deleting all VertexGroups!
- In PoseMode, the hotkey ALT+S now does both B-Bone size or Envelope,
depending draw type.
- In EditMode, Extrude now also works when only Root points were selected.
- Weight editing is also symmetrical btw, with the "X-axis Mirror" option
set.
RMB click drag to select and transform (grab). Release to confirm. (Cancel with esc)
The difference with before is that it is a single motion, you don't have to click at the end of transform, you can just release the mouse button.
(Some float constant warning too)
- Scale goes from 0 (original) to 1 (full sphere) instead of the contrary
- Mouse control is done by moving pointer left / right on screen. Full right is 1, left is 0. There's a 10% width padding on each border.
- Works correctly with Shift modifier now.
options on the Bone (G, R, S). The manipulator doesn't show btw.
Is usful to get immediate feedback on how painted weights behave with Bones.
Martin; I had to change the T_POSE behaviour in code a bit... it now
stores in TransInfo the actual posed armature being transformed. Maybe,
some day, we'll get mixed posechannel/object transform? Not much required
at the moment though. :)
*NOTE*: Some UI decision done in this commit will most likely be revised, all flame shall go in /dev/null. Constructive discussions of course welcomed.
This commit merges manipulator orientation selection back in "traditional" transform.
That's how it works:
- The dropdown in the 3D view header is always visible
- The orientation chosen will be used when choosing an axis with MMB and for the *second* key press of X,Y,Z
However, Local orientation doesn't use the one calculated by the manipulator. This is to ensure that multiple object local and armatures in pose still works as before.
- Alt-Space (to change the orientation) works during transform
New Transform orientation: View, using the view axis.
Fixes for the following bugs:
- Constraint projection code "jammed" if input vector was <0,0,0>, reported a couple of times on IRC. Thanks to Basse for the example file.
- Transform on texspace crashed on objects without texspace data (camera, lamp, ...). This was reported in tracker.
- Numinput with lock constraints didn't work correctly. Reported on elysiun
Probably some others that I'm forgetting
I also moved a couple of functions around in an attempt to make things clearer.
- 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.
- Bone points for B-Bone drawing were not adjusted for size of Bone, now
they draw same size as for other bone type
- Deleting bones in editmode didn't check for constraints in Pose, causing
weird collapsed poses or even crashes
- ALT+S scaling on B-Bones in editmode didn't correct for the Object scale.
The B-Bones!
(where the B can be read as 'block' or 'bezier' or 'b-spline')
- set option on/off in edit buttons, armature panel
- scaling of B-bones only works in editmode, use ALT+S to make bones fatter
or thinner. Also works for constrainted transform
- In pose mode, you now have a buttons panel with per-bone settings too
Here you can find the "segments" button, which allows bones to
interpolate between previous/next bones, including roll.
- Buttons to control interpolation ("In" and "Out" are disabled, doesn't
work satisfying yet
NOTE: this doesn't give deform yet! Main purpose for now is to test if this
drawing method serves to animate/pose armatures well.
Still need to review proper interpolation methods... maybe bezier is too
limited.
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-
Cleanup in transform.c: removed uneeded includes and removed REPEAT experiment.
Split off manipulator init function, no need to resort on hacks to setup stuff before starting transform anymore.
Fix0r3d single axis projection for constraints. It deals with perspective correctly now (as much as planar constraints).
Numpad Minus can now be used all the time to type negative numbers, without interfering with PET.
WARNING Behavior change: PET area of effect is not resized with Alt-Num+ and Alt-Num- (in addition to the scrollwheel)
WARNING testing needed: it's late and the laptop here has a funny emulated numpad, so better be tested on a real keyboard by someone who is not coding past midnight.
This because the used integer+float division could result in a
9.999999e-01 value, which is for acos() to return 3.452670e-04.
Converted the division to use doubles instead.
alone with the following flags :
-Wall -Wno-char-subscripts -Wno-missing-braces.
the only one still worrying me is in rand.c line 57 :
rand.c:57: integer constant is too large for "long" type
but i have no clue about how correct cross-compiler and 32/64 bits friendly
see also my mail to commiter list for signed/unsigned issues
- Ipokeys didnt have 'selected' flag, so were not included in center
calculus
- Multiple keys transform didn't apply this center even...
ALso took extra work time to add credits in splash. Frédéric Van der Essen!
MEMSET was clearing the TransInfo struct after the constraint setup call has been made.
Temporary fix until the manipulator transform init is split off, like normal transform.
CTRL+V on buttons
NKEY Panels
join mesh
join curve
editing buttons
boolean
vpaint
faceselect
Manipulator
Also; Transform() got in useless loop when you entered without anything
selected. Not sure why Martin recoded it this way... maybe as a first
step to handlerify it? For evil Python Aussie Bosses? :P
Using as Pivot the "individual object centers" didn't do any rotation or
scaling in editmode. I think it was supposed to give some kind of
'connected' centers, for individual faces/edges rotate. That'll be some
more coding work to get to work. :)
- Splited off the event treatment into a fonction of its own
- Splited off the initialisation phase into a function of its own (will have to do it for the manipulator function too)
Calling transform now works like this:
initTransform(mode, context)
- possible post init calls, constraints mostly
Transform()
- eventually, the postTransform function, so that Transform is just a simple big loop which could in the end just be tied in the blender event system instead.
- Added a state variable in TransInfo to replace the ret_val local variable. Possible values are: TRANS_RUNNING, TRANS_CANCEL, TRANS_CONFIRM
- Tied MMB and the hotkey select for constraint together, so selecting an axis with MMB and pressing the axis key after that goes to local mode on that axis. Much less confusing.
Martin; I've added calls like:
BIF_TransformSetUndo("Add Duplicate");
In advance of calling transform itself, to indicate that this is the
string name to be used for Undo, and also has to be done on ESC.
To make that possible I had to add a memset() to zero the global struct
TransInfo. Nicely done with if(Trans.mode==TRANS_INIT)
Not sure how this relates to setting constraints in advance... I always
found it tricky to work a non-initalized global struct. :)
