===========================
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.

functions for int & char.

Small type cleanup, use `GPU_Buffers *' rather than `void *'. Should
be no functional changes.
|
|
- Added support of variable size sensor width and height.
- Added presets for most common cameras, also new presets can be defined by user.
- Added option to control which dimension (vertical or horizontal) of sensor
size defines FOV. Old behavior of automatic FOV calculation is also kept.
- Renderer, viewport, game engine and collada importer/exporter should
deal fine with this changes. Other exporters would be updated soon.

* Adds two new python handlers: scene_update_pre() and scene_update_post()
These run before and after Blender does a scene update on making modifications
to the scene.
* Datablocks now have an is_updated property. This will be set to true in the
above callbacks if the datablock was tagged to be updated. This works for the
most common datablocks used for rendering: object, material, world, lamsp,
texture, mesh, curve.
* Datablock collections also have an is_updated property. If this is set, it
means one datablock of this type was added, removed or modified. It's also
useful as a quick check to avoid looping over all datablocks.
* RenderEngine.view_update() can also check these properties, for interactive
viewport rendering.

so path manipulation functions dont run multiple times on the same path in the case of sequence strips where the one directory is used as the base for many images.
|
|
lazely created but this wasn't done in a thread safe way.
|
|
|
|
|
|
template_list
|
|
(unavailable on some systems).
It allows to iterate over a string, returning an new element each time, using a char as separator. See BLI_String.h's comments for more info and an example.
Needed by the UI template list patch following!
|
|
|
|
changes.
|
|
- loop over all sequence images and pointcache
- option not to loop over library / packed data, expose in bpy.utils.blend_paths()
|
|
- added flag to optionally receive all paths as absolute.
|
|
Alex Fraser with additions.
this now supports as many types as bpath iterator which its intended to replace.
|
|
pass main rather than use G.main when naming from -> to relative paths.

|
- ensure input is valid utf8 from ghost and NULL then complain if its not.
- added function to get utf8 size BLI_str_utf8_size()
|
|
some parts of the code accounted for this but most not, always initialize the string to "".
|
|
made less cryptic and changed to indicate if they work on files or directories.
|
|
- removed AVG2, was only used once.
- remove unused LONGCOPY define.
- removed BLI_STRUCT_OFFSET, was only used once, replce with offsetof
- formatting edits, split some macros over multiple lines.
|
|
called the other, they did the same thing.
|
|
in BLI_ functions.
|
|
just call BLI_split_dirfile().
- add a fixed value for bprogdir (the dir of bprogname), since it was being used for resource lookups.
|
|
|
|
also fixed some spelling errors.
|
|
- also ifdef'd out more smoke function when the modifiers disabled.
|
|
unicode characters.
added BLI_str_utf8_as_unicode(), BLI_str_utf8_from_unicode()
|
|
|
|
include in each file
|
|
|
|
- move font.c unicode functions into string_utf8.c and rename to fit with other BLI_string funcs.
|
|
- rename define DISABLE_SDL --> WITH_SDL (which was already used in some places)
- blenders interation preset was using orbit rather then turntable 3d view preference (different from factory defaults).
- tagged some unused rna args.
|
|
size is known.
|
|
nothing to effect translations.
|
|
properly move the cursor with multi-byte chars.
Note that this is only for the interface, text editor and python console still miss this feature.
|
|
many places don't check for filename lengyj of 79 chars which is the limit for the file selector.
Add max dir and file length args.
|
|
didn't account for the case when destination string and dir string matched.
|
|
string.
starting blender in a dir longer then 240 chars would crash.
|
|
isn't used.

Looks like with current implementation voxeldata should always be created
for voxel textures. Remove recently added NULL check and allocate
voxel data when linking a texture.
