Camera tracking integration =========================== - ColaMD moved from OpenNL to extern/. It'll be needed for libmv. Also, it's a bit updated from year 1999 to 2007. Need to be tested for regressions. - Updated bundling script for libmv. Now it uses fuller subset of this library. - Bundled new libmv. - Request from Keir: add command line argument to toggle logging stuff on. Currently, if Blender is launched with -d argument libmv would start printing logging messages. There's no argument to increase verbosity, but there's API in libmv-capi, so it'll be easy to add. - Finally fixed crash when ibuf is acquiring with user=NULL. - Added ActiveClip property to the scene. This clip is used as default value for new match-moving constraints. - Added some flags to Display panel of View3D. Related on displaying match-moving stuff. - Internal change: bundles data moved inside to MovieTrackingTrack. - Initial implementation of 3d reconstruction. - Added constraint "Camera Solver". This constraint is supposed to be used to make camera follow the reconstructed camera path. - Added "reference" property to "Follow Track" constraint. Now object could be "parented" to 2D track position or to 3D bundle position. The very quick guide: To use reconstruction you should have footage with tracked markers, choose two keyframes in "Tracking settings" panel. There should be quite noticeable parallax effect between this two frames. This is used to initialize reconstruction stuff. Camera data (focal length and optical center) should be filled in "Camera Data" panel. Optical center is often the center of image, so it'll be filled in automatically. You should also set values for undistortion (K1, K2 and K3). Currently, there's no any visualization for this parameters and approach of "change value -> reconstruct -> see what've changed" is the only way for now. Libmv team is working on auto-calibration tool, so it should be easier to gather this coefficients in nearest (i hope) future. There's also no scene orientation stuff. Basic workflow: - Open footage. - Set markers and track them. - Fill in camera data and keyframes. - Hit "Solve Camera" button. - Add "Camera Solver" constraint to camera in scene. - Choose movieclip in that constraint. - To see bundles in 3D viewport active clip should be set in scene buttons.

May 31, 2007: version 2.7.0
* ported to 64-bit MATLAB
* subdirectories added (Source/, Include/, Lib/, Doc/, MATLAB/, Demo/)
Dec 12, 2006, version 2.5.2
* minor MATLAB cleanup. MATLAB functions renamed colamd2 and symamd2,
so that they do not conflict with the built-in versions. Note that
the MATLAB built-in functions colamd and symamd are identical to
the colamd and symamd functions here.
Aug 31, 2006: Version 2.5.1
* minor change to colamd.m and symamd.m, to use etree instead
of sparsfun.
Apr. 30, 2006: Version 2.5
* colamd_recommended modified, to do more careful integer overflow
checking. It now returns size_t, not int. colamd_l_recommended
also returns size_t. A zero is returned if an error occurs. A
postive return value denotes success. In v2.4 and earlier,
-1 was returned on error (an int or long).
* long replaced with UF_long integer, which is long except on WIN64.
Nov 15, 2005:
* minor editting of comments; version number (2.4) unchanged.
Changes from Version 2.3 to 2.4 (Aug 30, 2005)
* Makefile now relies on ../UFconfig/UFconfig.mk
* changed the dense row/col detection. The meaning of the knobs
has thus changed.
* added an option to turn off aggressive absorption. It was
always on in versions 2.3 and earlier.
* added a #define'd version number
* added a function pointer (colamd_printf) for COLAMD's printing.
* added a -DNPRINT option, to turn off printing at compile-time.
* added a check for integer overflow in colamd_recommended
* minor changes to allow for more simpler 100% test coverage
* bug fix. If symamd v2.3 fails to allocate its copy of the input
matrix, then it erroneously frees a calloc'd workspace twice.
This bug has no effect on the MATLAB symamd mexFunction, since
mxCalloc terminates the mexFunction if it fails to allocate
memory. Similarly, UMFPACK is not affected because it does not
use symamd. The bug has no effect on the colamd ordering
routine in v2.3.
Changes from Version 2.2 to 2.3 (Sept. 8, 2003)
* removed the call to the MATLAB spparms ('spumoni') function.
This can take a lot of time if you are ordering many small
matrices. Only affects the MATLAB interface (colamdmex.c,
symamdmex.c, colamdtestmex.c, and symamdtestmex.c). The
usage of the optional 2nd argument to the colamd and symamd
mexFunctions was changed accordingly.
Changes from Version 2.1 to 2.2 (Sept. 23, 2002)
* extensive testing routines added (colamd_test.m, colamdtestmex.c,
and symamdtestmex.c), and the Makefile modified accordingly.
* a few typos in the comments corrected
* use of the MATLAB "flops" command removed from colamd_demo, and an
m-file routine luflops.m added.
* an explicit typecast from unsigned to int added, for COLAMD_C and
COLAMD_R in colamd.h.
* #include <stdio.h> added to colamd_example.c
Changes from Version 2.0 to 2.1 (May 4, 2001)
* TRUE and FALSE are predefined on some systems, so they are defined
here only if not already defined.
* web site changed
* UNIX Makefile modified, to handle the case if "." is not in your path.
Changes from Version 1.0 to 2.0 (January 31, 2000)
No bugs were found in version 1.1. These changes merely add new
functionality.
* added the COLAMD_RECOMMENDED (nnz, n_row, n_col) macro.
* moved the output statistics, from A, to a separate output argument.
The arguments changed for the C-callable routines.
* added colamd_report and symamd_report.
* added a C-callable symamd routine. Formerly, symamd was only
available as a mexFunction from MATLAB.
* added error-checking to symamd. Formerly, it assumed its input
was error-free.
* added the optional stats and knobs arguments to the symamd mexFunction
* deleted colamd_help. A help message is still available from
"help colamd" and "help symamd" in MATLAB.
* deleted colamdtree.m and symamdtree.m. Now, colamd.m and symamd.m
also do the elimination tree post-ordering. The Version 1.1
colamd and symamd mexFunctions, which do not do the post-
ordering, are now visible as colamdmex and symamdmex from
MATLAB. Essentialy, the post-ordering is now the default
behavior of colamd.m and symamd.m, to match the behavior of
colmmd and symmmd. The post-ordering is only available in the
MATLAB interface, not the C-callable interface.
* made a slight change to the dense row/column detection in symamd,
to match the stated specifications.
