Start of planned DerivedMesh refactoring. The mface
interfaces in DerivedMesh have been renamed to reflect
their new status as tesselated face interfaces (rather
then the primary ones, which are now stored in mpolys).
short review: mpolys store "primary" face data, while
mfaces store the tesselated form of the mesh (generally
as triangles). mpolys are defined by mloops, and each
mpoly defines a range of loops it "owns" in the main
mloop array.
I've also added basic read-only face iterators, which
are implemented for CDDM, ccgsubsurf, and the bmeditmesh
derivedmesh. Since faces are now variable-length things,
trying to implement the same interface as mfaces would not
have worked well (especially since faces are stored as
an mpoly + a range of mloops).
I figure first we can evaluate these simple read-only
face iterators, then decide if a) we like using iterators
in DerivedMesh, b) how much of it should use them, and c)
if we want write-capable iterators.
I plan to write official docs on this design after I get
it more stable; I'm committing now because there's a rather
lot of changes, and I might do a merge soon.
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
Attempt to make multires updating a little cleaner by
assuming that no update needs to be performed, and only
doing the update when the modified flag is set (either
by sculpting or using some other tool that needs an update.)
-Many things not yet working properly :)
-Experimental new (hopefully more logical) categorization of buttons, feedback on this is very welcome.
-Separate render & draw types, for example now there is actually a render option "halo" instead of all the different point draw types.
-Particles get recalculated only from buttons that actually change something that has to be recalculated, for example changing visualization doesn't reset particles any more.
-Boid physics buttons are still missing as I'm currently redoing the whole boids code.
-Point caching is still very wip, so baking is not possible for example, but I added a few cache baking flags for rna that were/will be needed for particle buttons logic.
* Fix crash adding rigid body constraint.
* Give new nodetrees NT in ID name to make them recognizned by RNA,
even if the nodetrees aren't actual ID datablock.
Added a system for adding a "local" context in a UI layout.
This way you can define for example within a modifier panel
all operators to get the modifier in the context.
In the layout code:
uiLayoutSetContextPointer(layout, "modifier", &ptr)
layout.set_context_pointer("modifier", md)
In the operator:
ptr = CTX_data_pointer_get(C, "modifier")
md = context.modifier
* Added Constraints template and Add Constraint operator.
* Added toggle=True/False parameter to uiItemR, to get a
toggle button (actual button) rather than an "option"
button (checkbox)
* Added OPTION/OPTIONN button type, to distinguish with
TOG/TOGN.
RNA:
* Make all modifier pointers editable, including correct updates.
* Added notifiers and updates to constraints.
* Fix a stack corruption, pointed out by Andrea, and potentially
causing crashes.
Added subdivide operator and button for multires.
Since this seems to be the only modifier with an operator defined, I'm not sure if I put it in a good place or not, someone can check on this?
* template_modifier creates the modifier box, and returns a layout
to put the buttons in.
* Only the armature modifier is now done with python code, all other
modifiers use C code. To convert a modifier to python, remove the
corresponding C code and create a function in DATA_PT_modifiers.
* Some modifiers still require some RNA work to get it working well,
especially to make pointers editable. Mostly that is a matter of
defining an own _set callback and put some of the modifier C code
into it.
* Still various buttons that don't work, like for hooks or mesh
deform binding.
* Fix for crashing decimate modifier (still disabled).
* Removed UI_BUT_NO_HILITE, HMENU.
* Make uiLayoutBox work with align.
* Added material "type" property, with Surface/Volume/Halo
options, compatible with sim_physics, as requested for
material buttons layout. Obviously the Volume setting
does nothing currently.
* Deprecated MA_HALO flag in favor of this.
* Fix buttons jumping around when resizing and zoom. Part of this was
adding a tiny a 0.001f offset in UI_view2d_view_ortho, otherwise the
rounding is unpredictable (used to be 0.375f, but that was disabled).
* Fix various issues with zooming, panning panels. V2D_LOCKOFS_X/Y is
now taken into account in more places in the view2d code, to avoid
zooming into the center or panning out of the view.
* Remove "Free" align mode in buttons window (it's not really useful).
* View3D/Graph/Image editors now use the same PanelType system as the
buttons window, means some deprecated panel code could be removed.
* Some small visual tweaks for panels.
* View 2D Reset operator (Home key), to reset zoom and panning for panels.
* Added argument to set number buttons as sliders (slider=True for itemR).
* Ignore labels for button alignment (doesn't look right).
* Fix some use of context.main in py scripts, should get data from active
object instead.
* Fix autotexspace -> auto_texspace in py script.
Enable with WITH_LCMS (options have been added for scons).
lcms is very common on linux package managers, so no need to add in extern (IMHO). Libs for windows can be added to /lib
Code is mostly a proof of concept with hardcoded path for icc profile (taken from the lcms test suite).
Adding this now to svn so it doesn't rot on my hard drive. People interested in pushing it forward should feel free to dig in the code or poke me about it.
1) Remove WITH_FREETYPE2 from code, so now blender always need freetype2
2) Remove the old bmfont
3) Remove ftfont and bFTGL library
4) Implement a new BLF_draw_default function for place that still need/use
the old BMF api.
I try to update both, scons and cmake, but I only can test with make, so
hope all work fine.
MSVC is broken, but I don't have Windows, things to search and fix are
any reference to WITH_FREETYPE2, FTGL and BMFONT (take in care that
blenkernel also have a BKE_bmfont.h, this don't have anything to do with bmfont).
Always have to link/include the freetype2 library
Remove any reference to libbmfont
Remove any reference to libftfont
Remove any reference to libbftgl (or libbFTGL)
* Loading files saved with 2.5 works again now without crashing. Was crashing when trying to load Grease Pencil data (even though there was none)
* Fixed some msvc compiler warnings in own code
Time-Modifying F-Curve Modifiers now get special callbacks to allow them to specify what frame they need to be evaluated on, instead of forcing a re-evaluation of the preceeding curve + modifier-stack. This should be more robust than the old way in general.
It still remains to be seen if some tweaks to this are still needed, as the full consequences of the propogation of modified time-spaces have yet to be fully explored.
For now though, evaluation works by finding the last modifier on the stack which modifies time, and asks it what time it modifies the given time to. This modified time is used to evaluate the F-Curve data only. The modifier stack gets evaluated using the original time instead.
* Headers and menus can now be created in python.
* Replaced the uiMenuItem functions to create menus with equivalent
uiItem functions using a layout, removing duplicated code.
* More uiItem functions are now exposed to python.
* The text editor header, panels and one of its menus are now created
in space_text.py.
* Buttons window data context icon new changes depending on active
object.
Issues
* Icons are not wrapped yet, hardcoded ints at the moment.
* The ID browse template is unfinished.
Restored the code to get this working. I haven't tested this to verify it, but it 'should' work...
Also, deleted old gpencil.c file in editors, since it was causing compiling errors.
Patch from Joshua, converting Grease Pencil to 2.5.
All GP data now is an ID block, allowing re-use, link and append.
For better contextual control within 2.5, these GP ID's will get
linked to actual data, like NodeTrees, Scenes, Images or Objects.
That will ensure Undo works, and opens up exciting new use cases
as well. :)
Patch note: on reading files, GPencils linked from editors will
get moved to the main library, using standard naming (indicating
where it was used), and with "Fake User" set. That way the user
can manually relink the pencils where appropriate.
We can check on just linking GP to some default, like 3d window
pencils to Scene? Nice to experiment with.
Notes for Joshua:
- for reading old GPencil, it has to use old code as well, meaning
to tread data as "indirect data, within another ID".
- Saving ID data means the chunk in file BHead needs the ID_GD code,
and not "DATA", which indicates 'indirect data'. That's the file
format spec.
- I've added do_versions_gpencil_2_50(), feel free to further tweak
things here, like linking things to scene or so.
- Formerly GPencil saved 2.50 files won't convert gpencil
Now it is possible to write a Python Expression using the variable names for driver targets (see mockup from initial commit) to substitute the appropriate values into the expression.
In the __global__ namespace for PyDriver evaluation, the following modules are available:
* __builtins__ - i.e. the builtin Python functions
* bpy - new Python API
* math or m - math module
For example:
Consider a driver with three targets, named: A, B, C
Now, you could write an expression like:
C if A < 5 else B
or even:
2*C if A < 5 or A > 20 else m.PI*B
Of course, you don't have to have three targets, the above was just an example.
TODO:
* Bring back way to load pydrivers.py
* Blender.Noise equivalent would be nice to have
P.S. I hope I haven't made any terrible Python API coding errors here (i.e. mem leaks, etc.)
The Python API to define Panels and Operators is based on subclassing,
this makes that system more generic, and based on RNA. Hopefully that
will make it easy to make various parts of Blender more extensible.
* The system simply uses RNA properties and functions and marks them
with REGISTER to make them part of the type registration process.
Additionally, the struct must provide a register/unregister callback
to create/free the PanelType or similar.
* From the python side there were some small changes, mainly that
registration now goes trough bpy.types.register instead of
bpy.ui.addPanel.
* Only Panels have been wrapped this way now. Check rna_ui.c to see
how this code works. There's still some rough edges and possibilities
to make it cleaner, though it works without any manual python code.
* Started some docs here:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNATypeRegistration
* Also changed some RNA_property and RNA_struct functions to not
require a PointerRNA anymore, where they were not required (which
is actually the cause of most changed files).
Texture nodes hang when nodes have a cyclic case.
Added a (temp?) provision to tag node->need_exec zero for cyclic
nodes, and added check for this in texture nodes.
There was also a bug in 'tag changed' for texture nodes, which not
only tagged, but also called the tree exec (should not happen!).
In general the texture exec needs recode; it doesn't use the stacks
as provided per node, but recurses itself to previous nodes, giving
problems like this. Node execs should only do their own bizz, the
node system handles dependency and eval order nicely already.
