This is pure development option which is enabled by defining DUMP_FAILURE
or DUMP_ALWAYS libmv-capi.

Do not set root window as DND aware.

MAC_OS_X_VERSION_MIN_REQUIRED macros, to get more reliable version (api) covering

Merging just in case we'll want to develop some experimental stuff

The issue was caused by passing start iterator larger than end iterator
to std::copy in triangulation module. It'll do nothing on linux but will
throw an exception on windows. Now behavior will be identical on both
platforms.
Proper solution would be to figure out why exactly this happened, but it's
easier to be forwarded to Tobias and we'll need to get rid of triangulation
anyway.
This should solve issues:
#30100: boolean intersect crashes blender
#33001: Crash on applying Boolean difference modifier
#33045: Boolean modifier crash with mirrored objects

This fixes some "regressions" introduced in rev50781 which lead to much
worse solution in some cases. Now it's possible to bring old behavior back.
Perhaps it's more like temporal solution for time being smarter solution is
found. But finding such a solution isn't so fast, so let's bring manual
control over reprojection usage.
But anyway, imo it's now nice to have a structure which could be used to
pass different settings to the solver.

* Add access to the original indices for vertices
* Add a very simple C API for convex hull
* Add this patch to the patches folder and update readme.txt

- move object_iterators.c --> view3d_iterators. (ED_object.h had to include ED_view3d.h which isn't so nice)
- move projection functions from view3d_view.c --> view3d_project.c (view3d_view was becoming a mishmash of utility functions and operators).
- some some cmake includes as system-includes.

- Fixes several bugs within the Eigen library:

The Euclidean resection code had a magical constant, 1e-3, used to
compare the results of solving an equation. This failure detection
was well-intended, trying to prevent poor solutions from getting
made without notifying the caller. Unfortunately in practice, this
threshold is too conservative. Furthermore, it is not clear the
threshold should exist at all; the purpose of the Euclidean
resection is to come up with the best solution it can; other
methods (e.g. reprojection error) should be used to compare
whether the method succeeded.
This commit changes the Euclidean EPnP code to always succeed,
causing the previous fallback to projective resection to never
run. In most cases, this will result in better reconstructions.
This should, in most cases, fix the dreaded "flipping" problem.

The planar tracker uses Ceres for the refinement stage. During
refinement, Ceres iteratively updates the parameters with the
latest best guess. If the change in the parameters falls below a
threshold, Ceres will abort successfully ("converged").
For the case of pure translation tracking, the parameters are
exactly the two pixel shifts (dx, dy), and measuring the change in
these parameters gives a meaningful termination criterion.
However, for all the other parameterizations like affine, where
the parameterization involves affine parameters that have no
physical interpretation, Ceres is left with no way to terminate
the solver early. With the existing code, often many iterations
are run long after Ceres has found a solution sufficiently
accurate for all tracking needs. No one needs tracking with
a quadrillionth of a pixel accuracy; that time is wasted.
This patch extends the existing iteration callback that is passed
in to Ceres to check if the pattern has fallen out of the search
window, to also check if the optimizer has made a tiny step. In
particular, if the maximum shift of any patch corner between two
successful optimizer steps is less than a threshold (currently
0.005 pixels), the track is declared successful and tracking
is terminated.
This leads to dramatic speed increases in some cases, with little
to no loss in track quality. This is especially apparent when
tracking patches with affine or perspective motion models. For
example, on some tracking cases I tried, the iterations Ceres took
went from 50 to 3.

The planar tracker did not detect very skinny patches which have
effectively zero area and are untrackable. This adds detection and
rejection of patterns with zero area. This fixes a crash found by
during Mango production.

Sergey originally left a TODO() here, but his fix is the correct
one. I removed the TODO and fixed some comment issues.

It was an Abort() caused by check for solver result not equal to USER_ABORT.
In some cases solver returns USER_ABORT due to BoundaryCheckingCallback
detects coordinates does not belong to image.
Somehow this callback wasn't called in previous version of Ceres and
in the same case marker was jumping. Now when the callback is called
it seems we could simply return failure of tracking without aborting
Blender.
Probably this is in fact some issue somewhere else, would double
check with Keir about this.

Currently done as patch applied on bundling, would forward it to Ceres developers.
|
|
In some cases it was missed include of header file, in some other
cases symbol could be static.
|
|
Also mark non-public functions as static.
|
|
|
|
Now Ceres re-bundling should go smooth :)
|
|
|
|
|
|
Not sure if it'll solve all issues, but at least it should reduce
amount of errors.
Also added missed patch from previous commit.
|
|
Not sure why exactly this happens, would need extra investigation
and should probably be also fixed in upstream.
|
|
Such stuff better be solved in glog itself.
Should be pretty safe change since it was defined for CMake only
and AFAIR Jens wanted to get rid of this too.
|
|
This should contain real fixes for Windows, making it more robost and hopefully
faster (due to proper collection port) on that platform.
Also hack to fix Eigen alignment shouldn't be needed anymore.
Also on platforms which have got broken TR1 collections it's better to define
CERES_NO_TR1 instead of using Boost hacks. Made changes to Scons and CMake,
but can not check if this indeed works since i don't have OSX here.

Carve proved it's a way to go, so the time have came to get rid of old
boolean operation module which isn't used anymore.
Still kept BOP interface but move it to BSP module. At some point it
could be cleaned up further (like perhaps removed extra abstraction
level or so) but would be nice to combine such a refactor with making
BSP aware of NGons.
Tested on linux using both cmake and scons, possible regressions on
windows/osx. Would check windoes build just after commit.

by Daniel Stokes (kupoman) by applying a patch found in this Bullet bug report: https://code.google.com/p/bullet/issues/detail?id=525

- building without python works again
- rename maxi/mini to i_max/i_min (so thay are available for function names)
- some minor edits to IK stretch setting (no functional changes).
|
|
Note: Compile still fails during ceres compile (namespace tr1 problems).

having libopenjpeg installed.
|
|
|
|
the patches/ dir is NOT applied but perhaps we can get OSX and BSD working using the opj_config.h
|
|
also fix for building ghost test and fix double free in one of the tests
|
|
As far as i remember Keir, this should be safe for our usages of ceres
and it should save noticeable amount of time and used memory when
compiling blender with libmv support.
Quick tests with tracking went smooth after this.

Added option to use Grease Pencil datablock as a mask for pattern
when doing motion tracking. Option could be found in Tracking Settings
panel.
All strokes would be rasterized separately from each other and every
stroke is treating as a closed spline.
Also added option to apply a mask on track preview which is situated
just after B/B/W channel button under track preview.
