Accesible with Shift-P (was free), the behavior is much like Shrink/Fatten. Pull mouse toward you to pull toward center, push away to push away. Constraint and PET works with it too, of course.
Connected PET for mesh had an infinite loop in some case. Fixed an made a bit faster.
Renamed the numinput flag.
Corrected a conflict in TransInfo flags. This was a crash waiting to happen.
NO_CONSTRAINT flag now correctly used to disable MMB and constraint hotkeys when needed.
Added check for the manipulator flag when drawing them before applying transformation matrix. Was really weird when doing MMB with rotation.
The rest is proof of concept goody for a CONNECTED limiter for PET.
That is, PET affecting only elements which are connected together.
Only affects Curves right now since that was easier to test connectivity with. Still some polishing to do (falloff is based on distance of effect, not real distance), but it's a proof of concept, so...
- Added icons for the Widgets to blenderbuttons pic
- Added in header - if widget in use - three buttons to choose widget type
(hold shift for combo widgets)
- Hotkey CTRL+space now switches widgets on/off
I also noticed negative scaling doesn't work satisfying yet;
- for scale widget, using center didn't work correct anymore (fixed)
- negative scaling didn't even get applied! (fixed)
- but; scaling somethig negative now flips back to positive... ????
Last one i need Martin P for! Note that I had to change Mat3ToSize....
- center of rotation for camera in cameraview rotate has to remain the
camera center itself, drawing the dashed helpline then doesn't work,
since it's behind the camera clipplane. Just disabled that line.
- made MMB switch for cameraview grab to become quadratic, for a dolly
this feels OK, and makes it possible to move in small and large scenes.
- restored SHIFT modifier for translation and scaling. This based on old
convention that allowed precision editing on top of the transform you
already applied before pressing SHIFT.
Solved it with a new flag (T_SHIFT_MOD), since the G.qual cannot be
used. Transform() innerloop has to detect the SHIFT event itself.
Also coded it with storing the mouseposition while SHIFT event happened.
Hope Martin can approve! :)
- Martin's last commit made Manipulator Translate not work, it passed on
a zero translation to the constrainter, causing NaN's. Nicely catched the
exception.
- Fixed 'Trackball' to accept number input too
- Camera translate in camera view, with MMB, works again. Code needs
verification by Martin... it does it different now too.
- Camera rotate in camera view works again. MMB switches to 'trackball',
as formerly. Isn't consistant with other rotate+MMB though...
- rotate camera in cameraview around cursor doesn't 'feedack' anymore
Martin; I only use the TransInfo->persinv[4][4] now, but I think it's
safe to use viewmat and viewinv too?
- 4th rotation widget styling, activate with Scene buttons, Anim panel, "rt"
on "4".
- drawing constraint lines replaced with widget compatible styling.
(functionality unchanged)
Fix;
- click on center for Rotate widget didn't switch to local/normal in all
cases
versus perspective.
Note for Martin; still an issue with defining what positive/negative
rotation is in perspective... needs more math here!
- Added Transform Widgets for PoseMode
- made adding bones in EditMode setting G.moving, so it doesn't draw other
selected objects nor Widgets
Warning in commit of Martin yesterday: Trackball and initTrackball were
declared static, whilst also in transform.h. Quez; why are these functions
exported in the .h file?
To use; press the (temporal) icon in header. Switching widget types is by
pressing G, R or S once, if current widget type is different it switches,
otherwise it goes to normal Transform().
Widgets need a bit test for picking accuracy, correct drawing etc.
The rotate widget has a center button for 'trackball' rotate. That latter
can also be used for hotkey-based rotate.
In current code, all widgets remain in "Global" space, also in editmode.
Also widget updates while using normal transform has to be done.
2 Bugfixes:
- rotate in PoseMode had error for 2d 'around' center
- transform in postemode could crash, due to typo (& or |)
- Made framework for 3d Transform Manipulators (widgets)
- The Manipulators act like '2d buttons', by default with LeftMouse and with
while-hold-move-release
- Implemented now: Translation Widget, which allows:
- four hotspots for axis grab or view-aligned grab
- center defined by 'around' setting
- SHIFT+LMB gives planar constraint on other 2 axes
- works in Object mode and Edit mode (not posemode yet)
Enable it with (temporal) icon in 3D header. All other 'normal' transforms
then keeps working btw.
On the todo for this widget:
- choice for Global, Local or Normal orientation
The way the widgets are going to work is in review still. Commit is also for
Matt for his proposal/paper on topic.
Some notes regarding this project;
- no life updates (on mouse over) like 3DS, I think that's neurotic
- on click, dominant axis changes to theme defined "Transform" color, other axes disappear, like maya
- manipulater size is fixed preset, independent zoom.
- manipulator follows selection, and is located based on 'around' mode
Unresolved;
- in maya, when you select 2 or more objects, the manipulator draws on the 'active' object, also interesting
- what to do with G,R,S hotkeys? It could switch the manipulator "mode"...
- header button/menu for manipulator mode?
Constraint selection is now based on mouse motion (instead of pointer position).
What that means is that if you simply click MMB, it works exactly like it did with old transform (in 90% of the case, the last 10% is when MMB click was unpredictable in old transform because of extreme viewport orientation)
Also, since this means you don't really have a referential on which to base yourself, it draws a dashed line representing the mouse motion, starting at the center of the axis lines.
Please test and discuss, if this is better than before or not.
Fixed Extrude constraint. Needed to premul the normal by the object's matrix to but it in global space.
Also, moved the Locking Axis modifier (for constraints) from Alt to Shift. Alt was conflicting with middle mouse button emulation (reported in the test builds forum).
Tilt Transformation.
When that flag is set, numbers typed when the cursor is on the first position will affect all positions who do not currently have something typed for them.
Enabled Skey, 2, Enter to quickly double the size of something.
All modesty asside, it's coded rather smartly so it shows the cursor in every position that it will affect and lets you tab in undefined position to type in values there.
Thanks to Samadam for reminding me that the old code permitted that.
Brought back Shrink/Fatten. Changed the behavior a bit, move the cursor to the right to move toward the normal, to the left to move backward. Please comment.
Only works with meshes, defaults to resize otherwise.
Finish adding local constraints for multiple objects: One of the objects will have its axis highlighted lighter than the others. You control this one with your mouse and the others copy the motion on their respective axis.
Code changes: the TD_OBJECT flag is now a flag in TransInfo with the new T_POSE, T_EDIT and T_TEXTURE
- restored 'Warp' (Shift+W). Should work like before, including type mode
and holding ctrl/shift modifiers
- added CTRL event in queue, to only redraw when you press it. looks nicer.
+ Refined the headerprint for Translation. Now prints only the needed info for constraint in the constraint's space (ie: if you're moving 1 unit along the local X axis, regardless of it's orientation, it will print "D: 1.000 along local X")
Still need to make numinput work like that (typing a number with a local axis constraint would move along that axis. There's some base code already though, just need a finishing touch, but it's late now)
+ Optimised PET calculations by using the TD_NOACTION flag (actually, that might have been in the last commit).
+ Added a float axismtx[3][3] member to TransData to store the orientation of the element (useful for local axis constrainst which, in edit could be moving along normals and the like).
- Fixed scaling in edit mode (was doing some matrix multiplications in the wrong order, only visible when using a constraint)
- Fixed the constraint projection matrix. It didn't work for planar constraint if the constraint space wasn't global (in a nutshell, it produced weird results for local space planes).
- Some potential bugs fixed (Note to Ton: added an ext pointer in TransInfo to point to the TransDataExtension block. With the sort done after allocation, the first td pointer doesn't necesarely point at the start of the ext block, so we needed another to free it correctly).
- Got rid of some remaining test with G.obedit.
- Moved constraint reset from init to post trans code (Ton, that means you can create constraints before calling transform, like for the menus for example).
NOTE:
I was getting some random segfault with the new headerprint code. Very random, couldn't reproduce with a debug version. I did some initialisation that might have been missing (though doubtful that's what caused the crashes). Was linked to using constraint though not caused by them. Probably due to some dumb late coding error.
Made a generic snapGrid function. Now, each transform needs to define it's snapping parameters in their init. This is needed because of the constraint branching.
Renamed the constraints defines to CON_*
Renamed the fonctions used to interactively select a constraint (with MMB). The previous naming scheme was obscure at best.
Added a CON_SELECT flag when selecting interactively. (Following the idea of the patch joeedh submitted).
New behavior when selecting a constraint interactively, not only does it highlight the axis that will be selected, it also makes it the current constraint.
Holding down Ctrl when selecting a constraint with MMB now does the same as hitting Ctrl-AXIS. That is, it locks that axis (planar constraint on the normal plane).
- - - - -
To all those who posted suggestions, I'm not forgetting them:
- broken / desoto with the plane draw thingy,
- RobertT's push/pull transformation (that was from before the new code even)
- UnNamed's MMB interactive idea as we discussed on IRC
and all the others that I've noted down somewhere.
Next for today, I'll have a look at local constraint (object's axis).
Brought back functionality to work with "Ipo Keys" (Kkey in 3d window). New
transform code is looking more messy now... its design was not purposed to
clean on this level. Acceptable for this stage however.
Also renamed old variables *tob into *td.
Changed the meaning of mtx and smtx for objects. It's now uniform accross the board.
Added TD_OBJECT as a TransData flag. Objects is requiring exception code here and there, use a flag instead of G.obedit. Will document what the exceptions are for people who wants to add more transformations.
Split TransData in two.
Note to Ton:
You'll have to change posemode to use the new structure. I've left some variables as part of TransData to have a compilable version in CVS, remove them when you stop using them.
Check MetaElement and Object conversion for example on how to use TransDataExtension (though I'm sure you can figure it out by yourself).
And that's it. Not much coding time in the week days. :\
work. :)
- added static and (void) and some style stuff in transform.c
- first additions in code for posemode (do not even try now!)
- fixed warnings in previous commit martin (gcc only)
Note; posemode old transform had complex dependencies on redraw (Hos' home
grown dep graph), which is first being restored. Including old style
set_base_flags_for_editing. Tomorrow!
On a side note, Shear was fixed in last commit, just forgot to mention it. It wasn't acting correctly in Edit Mode (and Desoto was poking me about it every sunday).
- fixed warnings in compile (transform.h struct defines)
- drawPropCircle was on wrong location in editmode
- removed prop circle drawing for old transform (sorry, but we're going to
move soon anyway!)
- removed spaces from transform.c
Disabled behind defines. Uncomment //#define NEWTRANSFORM in transform.h to enable.
Use at your own risk

And tuhopuu mailing list: http://projects.blender.org/pipermail/tuhopuu-devel/
Notes for Ton (things that could need bulldozing:
- TransData conversions. Objects is ok, but others could be rechecked. (some still use totsel). Need to add pose mode support.
- Need more icons in the PET mode dropdown (in the 3D view header) for the new modes
- Add new transform calls to Toolbox and Menus and the one right after Extrude.
That's pretty much all I can think of now.
