This was never ported to a new tracking pipeline and now it's done using
FrameAccessor::Transform routines. Quite striaghtforward, but i've changed
order of grayscale conversion in blender side with call of transform callback.
This way it's much easier to perform rescaling in libmv side.
|
|
The title actually tells it all, this commit switches Blender to use the new
autotrack API from Libmv.
From the user point of view it means that prediction model is now used when
tracking which gives really nice results.
All the other changes are not really visible for users, those are just frame
accessors, caches and so for the new API.
|
|
Pretty much straightforward changes, nothing to be mentioned specially.
|
|
This starts the creating the new AutoTrack API. The new API will
make it possible for libmv to do full autotracking, including
predictive tracking and also support multiple motion models (3D
planes etc).
The first goal (not in this patch) is to convert Blender to use
the new API without adding any new functionality.
This API currently contanins:
- Frame accessor to access frames which are stored in Blender side.
- New Tracks implementation
- New Reconstruction implementation
Currently this API only tested on doing the same frame-to-frame
tracking as the old API allowed to do. But it also supports now
predictive tracking which is based on the Kalman filter.

to variables and functions
|

The ones in extern/glew-es have been changed to NOTE instead of XXX
GHOST_ContextEGL.cpp: It really does seem that it is not possible to query the swap interval using EGL
GHOST_WidnowCocoa.h: The comment referring to Carbon is clearly out of date, so I removed it.
math_geom.c: The node about not using tmax again is correct, but the code is kept for a future maintainer who will need to know how to compute it if they modify that code.
paint_image_proj.c (2698): The question about integer truncation does not appear to have been resolved. It still seems to be an incorrectly implementation of rounding (I'd suggest using the round function instead of this hack).

just to be sure we're dealing with the latest git version when troubleshooting
one annoying OSX issue..

Separates graphics context creation from window code in Ghost so that they can vary separately.
|

Add retake to range-tree to avoid double lookup.

We on'don't really support 10.5 anymore for my knowledge and in any case
the defined symbol was never checked in the sources, so this workaround
was basically doing nothing for quite some time now.

This way folks with few ram or those who wants to hack into Ceres
code might compile Blender much faster.
|
|
This makes headers a bit less clean (with the anonymous structs
mainly and headers inclusion from another header.
Makes compilation with clang a bit less noisy.
|
|
This brings faster BlockRandomAccessSparseMatrix::SymmetricRightMultiply.
|
|
Gives up to 2x speed up of camera solving process in average scene.
In the really huge one it might be slower, but that we need to investigate.
|
|
Mainly to let ITERATIVE_SCHUR use an explicit Schur Complement matrix.

Update lzo library due to security issue
Update lzo to latest version. This fixes a security issue (reported in T41974)
This also fixes some (false-positive) valgrind warnings.

Really weird linux and windows didn't have duplicated symbols error.

This commit makes it possible to use Glog library for the debug logging.
For now only possible when using CMake and in order to use the logging
the WITH_CYCLES_LOGGING configuration variable is to be enabled.
When this option is not enabled or when using Scons there's no difference
in Cycles behavior at all, when using logging and no output to the console
impact is gonna to be minimal.
This is done in order to make it possible to have debug logging persistent
in code (without need to add it when troubleshooting some bug and removing
it afterwards).
For now actual logging is not placed yet, only all the functions needed for
the logging are written and so.
|
|
This way maintaining the C-API is a bit less tedious job
and makes code cleaner to follow.
Should be no functional changes.
|
|
As usual brings fixes and speed improvements.
|
|
This would give some performance boost when solving huge scenes,
amount of boost depends on particular scene.
For now enable all of the specializations, in the future we might
add some local patches and restrict only unneeded ones.
|

The issue was caused by the wrong attributes maps in certain
circumstances after union intersections.
Namely issue might have happen when more than one iteration of
union was happening and it was caused by the fact that new faces
might be allocated on the same address as freed face from the
old mesh.
Didn't find a nicer fix for this apart from correcting the whole
attributes map after each union step.
We could try removing attributes for the meshes which are getting
deleted, but in asymptotic it's gonna to give exactly the same
complexity as the current approach.

This assert happens all the time for character physics in debug mode.
In release mode, the assert is skipped but the code is still incorrect
although it does not cause any crash strangely.
|
|
The typos didn't cause any bug, but the mis-ordered parameter names in CarveExporter_InitGeomArrays were confusing.

too large, change the argument to be the free space in the destination buffer minus the terminating null byte

For now it was mainly about OpenCL wrangler being duplicated
between Cycles and Compositor, but with OpenSubdiv work those
wranglers were gonna to be duplicated just once again.
This commit makes it so Cycles and Compositor uses wranglers
from this repositories:
- https://github.com/CudaWrangler/cuew
- https://github.com/OpenCLWrangler/clew
This repositories are based on the wranglers we used before
and they'll be likely continued maintaining by us plus some
more players in the market.
Pretty much straightforward change with some tricks in the
CMake/SCons to make this libs being passed to the linker
after all other libraries in order to make OpenSubdiv linked
against those wranglers in the future.
For those who're worrying about Cycles being less standalone,
it's not truth, it's rather more flexible now and in the future
different wranglers might be used in Cycles. For now it'll
just mean those libs would need to be put into Cycles repository
together with some other libs from Blender such as mikkspace.
This is mainly platform maintenance commit, should not be any
changes to the user space.

build environments and prepend SDK_FLAGS to CFLAGS always
|
|
Noticed this while looking into something else.
The change is trivial, but gives a rather nice preformance improvement,
so why not.
Theres's actually a lot one can do to improve collision performance if
one wanted to, the triangle-triangle check alone has a lot of room for
improvement.

This brings new copyright header which supports GPL2 and 3.
It wasn't really an issue before because we had agreement with
Tobias, but now it's all documented in sources.
|
|
Brings new bounds limiting and also prepares build system
for the changes in the upstream.
Namely shared_ptr header and namespace is now being detected
by a build system rather than by hacks in the code.
This commit includes some changes to auto-detection flags
in SCons, presumably adding more consistency there. This
is main changes which are suppoed to be reviewed here.

Currently covers only small set of functionality.
|
|
In the future i'd rather have this reported to an
upstream instead of adding local changes. It's really
easy to override this changes if patchset is not added
and this is to be fixed in upstream. Also the function
was never used so it was rather totally harmless warning
for us.
|
|
|
|
Mapping to original face was never working 100% reliably actually,
now use more robust method for this.
|
|
EXPECT_EQ wasn't defined in the scope.
|
|
It was rather stupid having it in brute region tracker,
now it is in own file in base library.
|
|
Pass the arrays by reference rather than by value,
should give some percent of speedup.
Also don't pass the dimensions to the function but
get them from the images themselves.
Hopefully this will give some %% of tracker speedup.
