===========================
Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.
More details about this project can be found on this page:
http://wiki.blender.org/index.php/User:Nazg-gul/GSoC-2011
Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
Editors Modules
* render/ module added in editors, moved the preview render code there and
also shading related operators.
* physics/ module made more consistent with other modules. renaming files,
making a single physics_ops.c for operators and keymaps. Also move all
particle related operators here now.
* space_buttons/ now should have only operators relevant to the buttons
specificially.
Updates & Notifiers
* Material/Texture/World/Lamp can now be passed to DAG_id_flush_update,
which will go back to a callback in editors. Eventually these should
be in the depsgraph itself, but for now this gives a unified call for
doing updates.
* GLSL materials are now refreshed on changes. There's still various
cases missing,
* Preview icons now hook into this system, solving various update cases
that were missed before.
* Also fixes issue in my last commit, where some preview would not render,
problem is avoided in the new system.
Icon Rendering
* On systems with support for non-power of two textures, an OpenGL texture
is now used instead of glDrawPixels. This avoids problems with icons get
clipped on region borders. On my Linux desktop, this gives an 1.1x speedup,
and on my Mac laptop a 2.3x speedup overall in redrawing the full window,
with the default setup. The glDrawPixels implementation on Mac seems to
have a lot of overhread.
* Preview icons are now drawn using proper premul alpha, and never faded so
you can see them clearly.
* Also tried to fix issue with texture node preview rendering, globals can't
be used with threads reliably.
- It is possible to work with MetaBalls in edit mode now
- Added basic UI to the button window (feel free to change it :-))
- Header menus should work
- Undo & redo should work
- Removed global variable editelems and lastelem (moved it to the MetaBall struct)
- All tools from old editmball.c was converted to the operators
- Added lastelem to the RNA
- Experimental: mb->editelems is only pointer at mb->elems or NULL (depends on Mode). ListBase of MetaElems is not duplicated in edit mode.
Tested with scons at Linux and mac OS X
TODO:
- Recalc data after Undo or Redo
- Solve issue with basic MetaBall and Python UI script (only base MetaBall object influence Wiresize and Threshold)
- Fix orientation of manipulator in "Normal mode"
* interactive console python console.
* display reports and filter types. defaults to operator display so you can see the python commands for tools as you use them,
eventually it should be possible to select commands and make macto/tools from them.
Example use of autocomp. b<tab>, bpy.<tab>, bpy.<tab>, bpy.data.<tab> etc.
basic instructions are printed when opening the console.
Details...
* Console exec and autocomp are done with operators written in python.
* added CTX_wm_reports() to get the global report list.
* The window manager had a report ListBase but reports have their own struct, switched to allocate and assign when initializing the WM since the type is not available in DNA.
* changed report types flags for easier display filtering.
* added report type RPT_OPERATOR
* logging operators also adds a python-syntax report into CTX_wm_reports() so they can be displayed in the console as well as calling a notifier for console to redraw.
* RnaAPI context.area.tag_redraw() to redraw the current area from a python operator.
Todo...
* better interactions with the console, scrolling, copy/paste.
* the text displayed doesnt load back.
* colors need to be themed.
* scroll limit needs to be a user pref.
* only tested with cmake and scons.
Added SpaceLogic, to restore the old logic buttons into.
In future it can be used for a more advanced logic editor, with
states, behaviour, whatever. We'll see!
This commit only adds the backend for new space. Committed this
now as reference for when we need another space type. It's still
not well plugin-able (dynamic space types), but my idea is to just
have a new SpacePlugIn for this, with a neat small API to define
all relevant callbacks.
Also note the icon for the spacetype is wrong still.
* Image painting back. 2d paint, 3d paint and projection, undo,
pressure, repeating paint operations, etc should all work.
Drawing cursor needs a bit of work, only gets shown when enabling
texture paint mode now.
* Move sculpt, image paint, and vertex/weight paint into a single
sculpt_paint module. Doesn't make much difference now, but nice
to have it together for better integration and consistency in
the future.
As creator of the Ipo I also reserve to right to kick it out
definitely :) To honour the wonderful contributions from Joshua
here it is; renamed space_ipo to space_graph!
Note; make, cmake and scons should work, msvc will require some
work now!
- Brought back code for particle edit and fluidsim
- Sanitized code from globals and bad level calls,
so its ready to come back working.
- Fixed cirle selecting (Ckey now)
- Enabled undo for editmode curve, armature, particle
and lattice
(another commit following)
- Previewrender code back, commented out a lot of bad cruft,
nothing works or is linked even!
- Added NC_GROUP notifier type, used in editgroup.c and
listened to in 3dview and outliner
Organized as follows:
uvedit/
uv editing related code
uvedit_draw.c: drawing code
uvedit_ops.c: operators, just a few done
uvedit_unwrap_ops.c: will be operators for unwrapping
uvedit_paramatrizer.c: lscm/abf/stretch/pack
space_image/
space_image.c: registration and common getter/setters
image_draw.c: drawing code, mostly functional
image_panels.c: panels, all commented out
image_render.c: render callbacks, non functional
image_ops.c: operators, only view navigation done
image_header.c: header, menus mostly done but missing buttons
Notes:
* Header menus consist only of Operator and RNA buttons, if they
are not implemented they're displayed grayed out. Ideally the full
header could work like this, but std_libbuttons looks problematic.
* Started using view2d code more than the old code, but for now it
still does own view2d management due to some very specific
requirements that the image window has. The drawing code however
is more clear hopefully, it only uses view2d, and there is no
switching between 'p' and 'f' view2d's anymore, it is always 'f'.
* In order to make uvedit operators more independent I move some
image space settings to scene toolsettings, and the current image
and its buffer is in the context. Especially sync selection and
select mode belonged there anyway as this cannot work correct with
different spaces having different settings anyway.
* Image paint is not back yet, did not want to put that together with
uvedit because there's really no code sharing.. perhaps vertex paint,
image paint and sculpt would be good to have in one module to share
brush code, partial redraw, etc better.
GPencil code back!
Joshua will probably take this further. I've added XXX notes
where fixes are required. Also note that ED_gpencil.h has
all old exports, which is probably not needed, most can go
to gpencil_intern.h
Also added Makefile fixes for sculpt
* curve, gpencil, physics and preview don't have sources yet, so scons fails on that. Disabled for now
Ton, when you actually put something in those dirs, remember to uncomment them in the editors/SConscript.
Added last few remaining modules in editors. Then the msvc
maintainer can already start typing! Only uv_paint is not
added, not sure how far Brecht is locally already.
* add SConscript to have it build with this buildsystem too :)
* commented out GHOST_Types.h - I guess any stuff that was used from it should be
properly done through event system (WM).
Put back Armature/Pose code, including 'heat weight'.
I've added reeb.h to get things compile, but Martin will
cleanup files and put back?
Now where to put all vertexgroup code.... I guess mesh?
Note for msvc: yep, another new dir to add! :)
* Added new 'Animation' submodule under Editors. This will be used to house all code + features that are used by many different Animation Editors (Action/Dopesheet and IPO) as well as other parts of Blender.
* Added back some of the core code need by the Action/Dopesheet editor, which will also be used by IPO Editor.
* Brought back file for keyframing management code (i.e. keyframing.c), but there's still quite a lot of missing stuff that I'll need to restore, so in the meantime, it's #if 0'd out.
* Moved markers code to this new module (I'm not sure whether SVN will recognise this change, as TortoiseSVN doesn't seem to have any obvious copy/move commands)
- Added file space (too) :) Andrea was first, this is more
complete.
- Suggestion from Joshua: move all standard header buttons to
1 function, makes it all easier, less code, and less area/space
stuff needs to be exposed.
The basics for InfoSpace.
Also added InfoSpace data to area by default, older files allowed to
have nothing here (space empty). (prevents reported crasher in switching
space info to others).
Also: added ifdeffed code in readfile.c to debug missing memory frees
from data read from files. (instead of "data from SCR" it will print
the actual struct names).
Resolved cyclic calls for editors.
Now there's a space_api/ module, here you can use functions calling
other editor modules. The functions in the module are only used by
the WindowManager module to initialize space types.
Note for sconzers and MSVC and cmake: the proper linking order for
editors is:
- space_api
- space_xxx
- object / mesh / transform / etc
- interface
- util / datafiles
- screen
- RMB select, also with SHIFT
- RMB tweak for translate
- SHIFT+D dupli
- BKEY border select/deselect
- AKEY (de)select all
- XKEY delete
- GKEY grab
Added some XXX comments for future todos, especially for when other
spaces come back with time markers.
Also added ED_util for putting in all to-be-cleaned cruft
Context conflict: input methods for Markers can conflict with other
spacetypes. It was solved in pre-2.5 with manually tweaking it all over,
but I would prefer one keymap for all marker stuff. Needs some thinking...
could be solved with a boundbox check for bottom part of 2d window.
Tweak issue: both tweak styles are possible:
- Hold mouse button, move, operator ends on mouse release
- Hold mouse button, move, operator ends on mouse click
Problem is that modally handled operators use fixed keymaps... like ESC,
SPACE, ENTER, or press/release mousebutton for 'assign'. There's a lot
to say for making this all consistant, or become part of 1 general keymap?
Should also be possibe to define 'tweak' defaults for Tablet different
than for mouse...
* Added RNA list viewer. This is currently drawn in the outliner
window, the UI is limited but it is just intended to test RNA
at the moment.
* Added UI names for currently wrapped properties.
* Made iterating collections a bit more convenient.
==========
* Changed wmOperatorType, removing init/exit callbacks and adding cancel
callback, removed default storage in favor of properties. Defined return
values for exec/invoke/modal/cancel.
* Don't allocate operator on the stack, and removed operator copy for
handlers. Now it frees based on return values from callbacks, and just
keeps a wmOperator on the heap. Also it now registers after the operator
is fully finished, to get the correct final properties.
* Changed OP_get_* functions to return 1 if the property is found and 0
otherwise, gives more readable code in my opinion. Added OP_verify_*
functions to quickly check if the property is available and set if it's
not, that's common for exec/invoke.
* Removed WM_operatortypelist_append in favor of WM_operatortype_append
which takes a function pointer instead of a list, avoids macro's and
duplicating code.
* Fix a crash where the handler would still be used while it was freed by
the operator.
* Spacetypes now have operatortypes() and keymap() callbacks to abstract
them a bit more.
* Renamed C->curarea to C->area for consistency. Removed View3D/View2D/
SpaceIpo from bContext, seems bad to keep these.
* Set context variables like window/screen/area/region to NULL again when
leaving that context, instead of leaving the pointers there.
* Added if(G.f & G_DEBUG) for many of the prints, makes output a bit
cleaner and easier to debug.
* Fixed priority of the editors/interface module in scons, would otherwise
give link errors.
* Added start of generic view2d api.
* Added space_time with some basic drawing and a single operator to change
the frame.
