which calculates texspace on demand if need be.
- removed almost all calls to tex_space_mesh
There may be a few corner cases where this goes wrong (meshes with vertex
keys) but these should get ironed out by coming modifier system.
- 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)
still a makeDispList that dispatches to the appropriate one.
makeDispList is on the way out and this makes it easier to track down
exactly which places use makedispList and for what types of objects.
- switch calls to makeDispList to appropriate more specific function (if
the object type is known by caller).
- added mesh_changed function that invalidates cached mesh data (but does
not rebuild, mesh data gets rebuilt on access). Most old calls to
makeDispListMesh use this instead now.
- Armature editmode, while armature was deforming children, was very slow
because it kept making subsurfs... this goes still hackish :)
- CTRL+A on armatures used loadsa old code, removed all of it! Still works.
- Using "Set smooth" or "Set solid" on file loaded without 3d window
crashed
had to add a new feature to the 3d window, to collect "after draw" objects,
which get drawn as last, after a clear of the zbuffer.
Same method can be used for nice OpenGL transparent draw, the system is
ready for it, do that later.
The huge commit is caused by cleaning up globals from struct Global. Many
variables were unused or just not needed anymore. Did that to move the ugly
G.zbuf to where it belongs, in the View3D space struct. :)
- 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
Seems to give issues in MSVC, and wasn't needed after all.
Further fixed dependencies in constraints between armatures and armatures.
It didn't update the other armature when the armature-object itself moved.
- Solid armature drawing didn't do well for negative scaled armatures
- Layer Ipos were not evaluated for invisible objects (there goes another
exception bypassing dependency...!)
- 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
This is mainly useful for scripts that generate/load datablocks for their own use and don't want to burry the user under an avalanche of datablocks he/she doesn't care about.
This adds a user pref "Hide .data" which now acts as a default value when opening a new fileselector.
It is also used when creating data select pop menus.
The "ghost" button in a fileselect window is independant from the userpref. It can be turned on/off individually without affecting
Note: When turning the option on/off, it sometimes take a couple of times before the pop menu registers it. Probably some caching thing. Will have to look at it.
Default value is Off.
extrema". It now also keeps auto-handles horizontal when the Y coordinate
is exactly identical.
And; made this option default on inserting new curve/keys.
Quite harmless, but was lazy code...
When you choosed "Vertex Color Paint" material, the init_render_material()
also set the "Vertex color Light" option, because that flag was checked on
during render to detect vertex colors.
Now it has proper checks in render code.
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.
actually) only the relative rotation is used.
- Added scale=1.0 initializer in saving files, this fixes a little bit
better upward compatibility
- Still there are cases where bones flip 180 degrees when you read it with
older Blenders... not sure what it is caused by
- ALT+R clear rotation on PoseMode didn't work when an Action was assigned
- 'Delete object' didn't set object pointers to NULL for Armature/Pose
constraints (old bug)
This fixes the active object in place when orbiting the view.

Image Memory Grabage Collection
This adds memory handling to the image code. An image is tagged each time it is used.
During a collection cycle (frequency of cycles is user defined), if an image is older
than a user defined limit, its buffer gets deallocated. This also applies to gl memory buffers.
Images that are loading in GL memory needs to go through two time outs before being fully deallocated: the first time out deallocated the gl memorry, the second the buffer in ram.
Notes:
Image buffer loaded from python gets tagged as permanent upon load. That tag is removed when python stops using the image.
I might have missed some tagging spots, especially in the rendering pipeline. Someone with more knowledge about this code should check to be careful.
Tagging is done on every access, for rendering, this will probably be a performance hit. A scheme should be developped to only tag when the rendering is completed.
Collecting is called in draw_object, most likely not the best place to do it.
Safe from undo, since using undo deallocates memory anyway (like when loading a blend file with one currently opened)
Userpref DNA changes:
I've changed a couple of flagging variables from short to int. Some because they needed more space, others to keep SDNA happy.
Info window changes:
I've grouped a couple of buttons in aligned blocks and changed the color of mutually exclusive options to make them clearer.
Matt didn't do any changes on that in tuhopuu, so hopefully I'm not stepping on anyone's feet with this.
Also changed double constants into floats with f in a couple of places (mostly space.c) to make compiler happier.
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-
INIT_MINMAX and INIT_MINMAX2 are always used on floats but use doubles for initializing, giving countless warnings.
Added the nice 'f' to tell compilers that we want floats.
- For avoiding the 'overlapping character problem' in Text objects, I had
changed the sorting code for filling nurbs to use nu->charidx (a new
variable incremented with each new character) instead of nu->mat_nr
(which used to work for material indices inside a 2D Curve).
- This broke material indices in normal 2D Curves completely, thus:
- nu->charidx is now not only used for seperating
characters in text objects for filling, but also for normal 2D curves
when they contain material indices. In fact, charidx is just set to
the material index.
- There's compatibility code in readfile.c that sets nu->charidx to nu->mat_nr
when reading curves from files that are not text objects
- So, the big conclusion: Instead of using material indices for creating
'filling groups', filldisplist() now uses nu->charidx, which is set
appropriately when reading old files and assigning/deleting material
indices in curves.
- This is all pretty obscure and hard to explain. If I haven't been clear,
ask.
- If it breaks anything, complain!
correct (although fairly unnoticable).
- bug fix, vertex normal calculation didn't normalize face normals before
summing... silly mistake
p.s. perhaps the Crystal Space bla bla naming conversation is not most
appropriate for the commit list?
"Flush":
- There are now two modes, "Flush" and "Justify". Justify only flushes
a line when it is *terminated* either by wordwrap or by Enter.
- "Flush" *always* flushes the line, also when it's still being entered.
This mode can be used for things like this:
http://pub.intrr.org/flush.png
..while "Justify" would not flush the second line.
- Fixed "Flush" squeezing all characters on the same spot if the textframe
was set to 0 width
- Improved text editing for justified ('Flush') text: Line will not
be filled up until it is completed (wordwrap or Enter)
- Fixed waitcursor flickering in displist.c
Important notes:
- Full compatibility with old text objects not fully restored
(word spacing will be 0.0, need to set it manually to 1.0), will
either need version upgrade to 238 or a hack. Will check.
- lorem.c (about to be committed) contains BF copyright notice, but as
BF did not exist a few hundred years ago, probably best to remove it :)
- If you notice any cross-platform issues (especially beloved windows),
please report
- A few tiny warnings left, I will fix those issues still.
The rest has been said already - so have fun testing. And please do!
