- added faces.uvSel attribute: can get/set selection status of UV vertices in
UV Editor window
- make mesh.faceUV, mesh.vertexUV and mesh.vertexColor writable: users
can now enable/disable UV faces, vertex colors, "sticky" vertices
- fixed bug with mesh tool methods: before it would only work if an object
linked to the mesh was selected
- added mesh.quadToTriangle() and mesh.triangleToQuad() methods
- added selected() method to verts, edges, faces; returns list of indices
of selected items
- mesh.getFromObject() now gets derived mesh data
- ported vertex group methods from NMesh (required change to Object.c)
- ported module dictionaries from NMesh
- Discombobulator by Evan R and DirectX8 Exporter by Ben Omari.
BPython:
- Crashed Blender while testing discombobulator: obj.setMaterials() was not checking if the passed obj had valid obj->data. If the object had been created and not linked yet to a mesh, a crash would happen when trying to sync ob and me material lists. Now an error is returned. Also made obj.setMaterials accept an empty list, since obj.getMaterials can return that.
Thanks to the script authors for the updated versions and special thanks to Tom (LetterRip) for collecting info about updated and new scripts, sending me updates I had missed, etc.
Changed Object.link() to allow link objects with both BPython-type meshes
Changed Object.getData() to allow retrieving both types of BPython-type meshes
Added new mesh types to Types module
- #2781, reported by Ed Blake: crash on undo when there were active space handlers. Space Handler script links belong to screen areas, which do not get saved on undo. Thanks Ton for pointing out the function that restores ui pointers gone bad.
- Applied patch #2822 by Ken Hughes for bug #2647 ("Setting a Face UV"), reported by Campbell Barton.
- #3022, reported by Timothy Wakeham: "Blender.BGL.glDrawPixels crashes when drawing more pixels then buffer size". Made glDrawPixels check buffer dimensions.
- #2882, reported by Campbell: crash in nmesh.getMaterials(arg == 0 or 1) when nmesh came from GetRawFromMesh(). Raw nmeshes are not linked to Blender meshes, so the method doesn't support these options (getting mat info from the actual mesh) for it.
- #2817, reported by Tod Koeckeritz: Dir_Depth var was not being decremented in BPY_Menus.c, causing dir depth limits to be reached prematurely.
- #2954, reported by Daniel Holtz: "Python scripts crash hard with valid windows paths". Blender.Load() was not meant for background mode, now it's been update to support it, using BKE_read_file instead of BIF_read_file in this case. Also found another issue with command line scripts using Blender.Load() that could crash Blender: trying to free the Text when it wasn't available anymore (loading a new .blend already removed it). There are still issues with one case, though, causing a crash on start or "Memoryblock winopen: double free" at end, when running a script that is already a Blender Text (only if the script calls Blender.Load, of course). Will investigate.
- #2897: reported by Timothy Wakeham: object.setMaterials was asking the length of a Python list w/o confirming first if the passed obj was really a list.
Thanks all for the help and for being patient (long delay, again).
- corrections to constants
- parameter type checking
- correct use of METH_VARARGS vs METH_NOARGS
- return objects instead of strings in Scene.getChildren() as per doc.
- correct logical operators
Thanks, Ken!
to get rid of faces with MFace.v3==0
- change all Mesh's to have ->medge now. This is forced by make_edges
on readfile, and in the various exotic important routines, and on
conversion back in python.
- make python NMesh structure always have medges now (needs testing)
- with above two changes it is guarenteed that mf->v3 is never ==0
in main blender code (i.e., all MFace's are actually triangles
or quads) and so I went through and removed all the historic tests
to deal with MFace.v3==0. Equals lots of deleting, I am in heaven!
- removed MEdge edcode flag, no longer needed
- added experimental replacement for edge flag system
Still are some inconsistencies in FACESELECT mode edge drawing to
be ironed out.
NOTE: This commit adds an experimental edge flag calc system, based
on 10-seconds-of-thought algorithm by yours truly. Would appreciate
feedback on how this system works, esp compared to old one and esp
on complex or interesting models.
To Use: New system is enabled by setting G.rt to a value between
1 and 1000 (Value of 0 uses old system). Value 1000 is reserved for
"auto" edge, which is more or less identical to old system but also
makes sure that at least 10% of edges are drawn (solves errors for
super subdivided meshes). Values between 1 and 999 act as percent
(out of 1000) of edges that should be drawn, starting with "most
interesting" edges first. Please try it and comment!
variables, these are still in same place. enable button automatically
makes/enables modifier.
- changed hook to hook modifier conversion to happen on direct link,
required to make sure we don't forget to free any memory for files
saved with 2.38 that have hooks.
- update modifier interface to enforce modifiers with the require-original-
data flag to not move beyond deforming modifiers.
- enforce only one softbody modifier allowed
NOTE: Once again, no modifier stack for lattice yet means softbody for
lattice does not work atm.
- Mostly this cleans up the #includes and header files in the python project.
- Warning fixes are mostly casting issues and misc fixes. General warning clean up.
- #include Python.h MUST come as the first include to avoid the POSIX redefine warning in the unix makefiles
- fno-strict-aliasing flag added to makefile to fix a unavoidable type punning warning in types.c
- appropriate callers of makeDispList replaced with depgraph calls
- unappropriate places just killed... small chance this gives some
errors in corner cases if dep graph isn't notified (example, font
family displists) but these can be tracked down as they show up.
- still a large number of callers of makeDispListCurveTypes, but
makeDispListMesh has just a few.
This adds two new method to the BPY Object type:
- makeParentDeform
- makeParentVertex
Both are based on makeParent. In fact, I splitted off the parenting
part of makeParent into an internal function so that all can reuse it. I
also added DEP_graph refresh flag that where missing.
makeParentDeform sets the parent type accordingly for correct
deformation (armature and curve) and checks if the parent and childs are of the
correct type for deformation.
makeParentVertex takes as additional mandatory argument a tuple of
indices to tell the parent which vertex to use. It does some object type
checking too.
Also included documentation. :)
Test file is in the patch there: http://projects.blender.org/tracker/?func=detail&atid=127&aid=2833&group_id=9
Note to Ton: When doing vertex parenting, the dashed parent line is only updated correctly if the objects are on screen when calling the function. If they aren't, the line is wrong and is only corrected when another recalc is called on the parent or child.
- switch all mesh boundbox access to go through mesh_get_bb
- switch object_handle_update to call mesh_changed instead of making
the displist data immediately (delayed calculation)
- also included is some fixes for preprocessor inclues and some clean up of the previous commit
-rewrite and bugfixes
----------------------------------
Here's my changelog:
-fixed Rand() so that it doesn't seed everytime and should generate better random numbers
- changed a few error return types to something more appropriate
- clean up of uninitialized variables & removal of unneccessary objects
- NMesh returns wrapped vectors now
- World returns wrapped matrices now
- Object.getEuler() and Object.getBoundingBox() return Wrapped data when data is present
- Object.getMatrix() returns wrapped data if it's worldspace, 'localspace' returns a new matrix
- Vector, Euler, Mat, Quat, call all now internally wrap object without destroying internal datablocks
- Removed memory allocation (unneeded) from all methods
- Vector's resize methods are only applicable to new vectors not wrapped data.
- Matrix(), Quat(), Euler(), Vector() now accepts ANY sequence list, including tuples, list, or a self object to copy - matrices accept multiple sequences
- Fixed Slerp() so that it now works correctly values are clamped between 0 and 1
- Euler.rotate does internal rotation now
- Slice assignment now works better for all types
- Vector * Vector and Quat * Quat are defined and return the DOT product
- Mat * Vec and Vec * Mat are defined now
- Moved #includes to .c file from headers. Also fixed prototypes in mathutils
- Added new helper functions for incref'ing to genutils
- Major cleanup of header files includes - include Mathutils.h for access to math types
- matrix.toQuat() and .toEuler() now fixed take appropriate matrix sizes
- Matrix() with no parameters now returns an identity matrix by default not a zero matrix
- printf() now prints with 6 digits instead of 4
- printf() now prints output with object descriptor
- Matrices now support [x][y] assignment (e.g. matrix[x][y] = 5.4)
- Matrix[index] = value now expectes a sequence not an integer. This will now set a ROW of the matrix through a sequence. index cannot go above the row size of the matrix.
- slice operations on matrices work with sequences now (rows of the matrix) example: mymatrix[0:2] returns a list of 2 wrapped vectors with access to the matrix data.
- slice assignment will no longer modify the data if the assignment operation fails
- fixed error in matrix * scalar multiplication
- euler.toMatrix(), toQuat() no longer causes "creep" from repeated use
- Wrapped data will generate wrapped objects when toEuler(), toQuat(), toMatrix() is used
- Quats can be created with angle/axis, axis/angle
- 4x4 matrices can be multiplied by 3D vectors (by popular demand :))
- vec *quat / quat * vec is now defined
- vec.magnitude alias for vec.length
- all self, internal methods return a pointer to self now so you can do print vector.internalmethod() or vector.internalmethod().nextmethod() (no more print matrix.inverse() returning 'none')
- these methods have been deprecated (still functioning but suggested to use the corrected functionality):
* CopyVec() - replaced by Vector() functionality
* CopyMat() - replaced by Matrix() functionality
* CopyQuat() - replace by Quaternion() functionality
* CopyEuler() - replaced by Euler() functionality
* RotateEuler() - replaced by Euler.rotate() funtionality
* MatMultVec() - replaced by matrix * vector
* VecMultMat() - replaced by vector * matrix
- New struct containers references to python object data or internally allocated blender data for wrapping
* Explaination here: math structs now function as a 'simple wrapper' or a 'py_object' - data that is created on the fly will now be a 'py_object' with its memory managed by python
* otherwise if the data is returned by blender's G.main then the math object is a 'simple wrapper' and data can be accessed directly from the struct just like other python objects.
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

- fixing bug reported by Paolo Colombo: space handler slinks set for a 3d view were not set when the area got maximized;
- Blender.Object: added object.isSB() method to know if an object is a soft body (has ob->soft != NULL). Used in fixfromarmature.py.
Scripts:
- updates: batch_name_edit (Campbell), fixfromarmature (JMS);
- additions:
X3D exporter by Bart;
Envelope Suite by Jonas Petersen;
BVH 2 Armature by Jean-Baptiste Perin;
Camera Changer by Regis Montoya (3R);
Interactive Console by Campbell (ideasman).
- tiny updates in other scripts.
Works as follows;
- press the 'show bake settings' button (no space left... :)
- define start/end frame for bake, and an interval step.
The baked result interpolates nicely (Bspline, 4 keys) so in general a
step size of 2 or 3 still gives OK results.
- Press "BAKE". This will do a full animation + playback. Press ESC if it
you don't want it.
Once Baked, the BAKE button becomes a FREE BAKE. As reminder the softbody
buttons get blocked with error() menu.
This saves OK in a file. Renders any frame, including fields and moblur.
You can also set a "Timeoffs" for the softbody. And yes, this should be
in the NLA once... :)
NOTE! With this commit, files saved with the old (first commit) version by
Jens Ole won't read the settings back... he stored all sofbody variables in
Object, which was moved to a new struct when I did my first commit on SB
(over a month ago)
Also note that I moved particle deflecting & softbody to a new include.
- based on a request by Campbell (he also provided a patch for scene.Layer) access to layers was improved a little, keeping the old method (ob.Layers is a bitmask) and adding the nicer one (ob.layers is a list of ints). Done for objects and scenes. House-cleaning: .Layer was renamed to .Layers (actually just using strncmp instead of strcmp, so both work, same done for Window.ViewLayers).
- finally committing patch by Ken Hughes to let .clearScriptLinks() accept a parameter (list of strings) to clear only specified texts.
- doc updates and fixes (JMS reported a problem in nmesh.transform() example code).
Thanks all who contributed.
Also adds docs for above API.
My testing cases seem to work fine. Please test to make sure I have not
missed anything!
Stivs, I got ascotan's signoff on thses. But please make any adjustments that
you deem needed.
Johnny
-includes:
*Text3d accessors - ablity to manipulate FONT objects through python
*update to Object.link - calls text_to_curve upon ob_font link for drawing
*update to constant.h - constant type checking define
*update to curve.c - clamp values on getters/setters
*clean up of Text3d module
- Gert de Roost reported an inconsistency between nmesh.getMode and .setMode. Now .setMode() optionally accepts an int value, as returned by getMode().
- Campbell Barton pointed that object.getData(name_only=True) was by mistake returning the obj name, not the obdata name, as it should. Fixed now.
- small doc updates
Thanks both for the reports.
- applied Campbell Barton's patch for access to Oops location and selection of materials, mesh data and objects, slightly modified. Thanks, Campbell;
- got rid of warnings in many files, hopefully not introducing any other during the process. Mostly this was done: 1) new EXPP_incr_ret_True/False functions were added and used instead of "Py_INCREF(Py_True/False); return Py_True/False;". Currently at least the functions use the fact that PyTrue/False == 1/0 and use 1 and 0 to avoid the warnings. 2) Filling of certain types structs got 0's added for all not defined data and methods. This is surely Python version specific, since these structs can change size and content at each major version number Python update.
- NMesh: made nmesh.update accept an optional 'vertex_shade' param to init vcols with shading info, like when you enter vpaint mode or press the relevant "make" button for a mesh without vcols. This is still a test, the functionality was requested by Manuel Bastioni for the SSS script they are working on:
http://www.dedalo-3d.com/index.php?filename=SXCOL/makehuman/articles/subsurface_scattering_in_python.html
- sys: made makename() accept files with max FILE_MAXDIR+FILE_MAXFILE name length, should fix#2192. Was only FILE_MAXFILE, a mistake;
- Image: added .setFilename(), contributed by Campbell Barton;
- Camera: added camera.get/setScale for the new param added by Ton for ortho cameras. Requested by Jean-Michel Soler for the Texture Baker script;
- related doc updates.
- Fix related to bug #2157: crash in Blender.Image.image.reload() method. "G.sima" was not being checked for validity. Fix by Joilnen B. Leite (pidhash). Thanks!
http://projects.blender.org/tracker/?func=detail&atid=125&aid=2157&group_id=9
- Added optional argument to Blender.Object.object.getData() method: getData(only_name = True) or (only_name = 1) or (1) will return only the obdata name, not a wrapper for the given struct. This is a test based on a request by Campbell Barton who submitted code for his proposed .getDataName() method (thanks!).
- doc updates and small fixes.
- Fixes by Jean-Michel Soler: mod_ai2obj.py, mod_svg2obj.py;
- Fixes by Campbell Barton: obj_import.py;
- Small fix to mod_meshtools.py (fixes bug #1605: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1605&group_id=9);
- Updates by Jean-Baptiste (Jiba) to his blender2cal3d.py;
- Updates to all his import / export scripts (added doc data) by Anthony D'Agostino;
- Update to off_import: support for uv data, by Arne Schmitz.
BPython:
- Removed Object.get and .getSelected (deprecated long ago, we use .Get and .GetSelected) -- fixes#1861: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1861&group_id=9
- Applied patch by Michael Reimpell: quat.c - fix for wrong initialization with newQuaternionObject; Mathutils documentation improvements.
- Stani reported a wrong return msg in IpoCurve.Get (that is unimplemented).
Thanks to all coders mentioned above!
-- fixed bug #1689:
http://projects.blender.org/tracker/?func=detail&atid=125&aid=1689&group_id=9
Reported by Tom Musgrove (thanks), the problem was that Window.QHandle was not passing events to windows that had id's below the current active window. It was a stupid mistake (mine), the code was iterating from curarea instead of from the first area in the areabase list.
-- fixed bug #1568:
http://projects.blender.org/tracker/index.php?func=detail&aid=1568&group_id=9&atid=125
Stephen investigated the problem, reported by Gabriel Beloin, and left hints in the bug report, thanks :). I also implemented what he suggested, now Effect.Get('objname') returns a list with all objname's effects and as before, Get('objname, position') returns the effect at position 'position'. Ref doc already updated.
-- Allowed menu registration lines to appear commented out -- Python comments: '#', of course -- (suggested by Michael Reimpell) in scripts:
Some Python doc tools need the doc strings between triple double-quotes, so to avoid conflicts scripts writers can now comment out the registration code, it should work anyway. Michael also provided a patch for this a few days ago, too (thanks), but to keep changes at a minimum because of proximity to a release I didn't use it.
- Blender.Window: added function GetPerspMatrix() (Tom Musgrave's patch, thanks);
- added Chris Want's patch to tell argc, argv to the Python interpreter (thanks, Hos);
- Blender.Image: added image.glFree() to free textures bound by the recently added
image.glLoad() (both suggested by Campbell Barton -- thanks, with these Blender can
be used to load textures for scripts);
- Blender.Sound: removed for now at least a few get/set methods of vars that can't be
accessed via interface;
- renamed Get/makeActive to Get/setCurrent in Blender.World (actually added alias for
now), same in Blender.Sound: renamed makeActive to setCurrent. Stephen Swaney
pointed this some weeks ago, we should stick to one naming convention.
- added documentation for Sound and Window.Theme modules and the other added
functions, made other small updates.
- Blender.Object: made 'worldspace' become the default output of .getMatrix and .mat/.matrix:
after reading a discussion on blender.org's Python forum where eeshlo mentioned the
pre 2.34 default was worldspace, I took a better look at Blender's relevant code,
confirmed, talked to Theeth about this and as he suggested am changing the default
back to 'worldspace'.
