investigation lead to finding 3 bugs here...
- transform key input handling didnt ignore minus key on an unsigned value as it should.
- not being able to set numcuts to 0 made typing in numbers not very useful.
- backspace would set the cuts to an unsigned value.
Changed one of the intersection tests to use < rather than <=
The sharp and smooth modes look fine now for the special case that was
reported broken; blocks mode looks correct but "jumps" slightly from
one octree resolution to another, so may need additional corrections.
Currently only put sources of Ceres library into extern/libmv/third_party and
setup CMake and SCons building systems.
Integration details:
- Even CMake build files are not re-used from Ceres's trunk: they're using some
automatic stuff detection like glog, pthreads, protobuf and so and it's not
so clear how to re-use that files without modifications.
And IMO it's easier if build files are getting re-generated automatically to
match Blender-specific setup rather than keeping changes made locally in
Blender in sync when re-bundling Ceres library. Especially in case when it's
alerady needed to support SCons build system.
- Integrated only actual sources, all tests were stripped. Probably it'll be nice
to have them, but they'll need clear integration with current module test stuff
in Blender.
Hopefully integration went smooth.
- Suitesparse was disabled. It'll help a lot having it, but there are some difficulties
making cholmod working fine on windows. Would be added in future
- collections_port.cc was also stripped. It's not used by Ceres's upstream and
it gives compilation error (undefined uint32 -- looks like namespace issue).
- Currently all schur eliminators are included. Not sure if it makes sense,
also not sure if it makes sense having them switchable on and off -- IMO better
to have single configuration which works and does not require special tweaks
after everything was set up.
- Personally i'd say if some of Ceres modules are not used better to drop it
away -- all symbols would be stripped anyway, but it'll be waste of compilation
time which is annoying in cases when one doing, say, binary search of revision
at which some regression was introduced. Especially when it's easy to add modules
which should be used by Blender.
But as long as it stays in Tomato i'm not worrying much about this.
To bundle updated version of Ceres:
- You'll need to use GIT-SVN checkout,
Re-bundling Ceres using SVN is still NOT supported!
- Go to extern/libmv/third_party/ceres folder
- Run ./bundle.sh
This will checkout fresh Ceres snapshot of Windows branch (which is currently
most interesting from integration into Blender POV), apply all patches listed
in patches/series and copy needed files into Blender's working copy. This will
also re-generate CMake/SCons build rules.
If you'll need extra files from Ceres repository which are not present in
Blender, you'll need to copy them manually and then run ./mkfiles.sh from
extern/libmv/third_party/ceres folder which will update list of files used
by Blender.
Thanks all Ceres developers for this library and thanks to Keir Mierle with
help integrating Ceres into Blender!
from Sebastian Nell (codemanx), with some edits
- Changed key shortcut to Shift+Enter.
- made into its own operator since it works differently to delete.
- Fixed suddenly disappearing preview image from track widget
- Also suddenly stopping tracking should be fixed now
Both issues were caused by mixing working with floats and bytes and
in some cases it was wrong or missed checks done for this.
** I did not update rst docs. I will post on the quick-hack list. If no one volunteers to do it, I have it done before next release. **
this patch add the barebone functions to do glsl shaders in an addon.
For simplicity sakes it supports old GLSL, but not all the new modern methods (glBindFragDataLocation, ...).
It should be enough to make an addon to help with bge 2d filters.
I'm using this with a 3dview callback and it's working nicely:
self._handle = context.region.callback_add(draw_callback_px, (self, context), 'POST_VIEW')
I was considering not to commit this patch due to it not covering all OpenGL new methods.
But frankly it's not the first time bgl is expanded upon individual needs (guilty of that myself).
If a python developer knows enough to use OpenGL and need new functions, s/he should also be able to patch Blender for that,
so I see no problems here.
Another solution is to move to PyOpenGL or similar any soon.
glShaderSource implemented differently than opengl standards. It's taking one source at a time (instead of an array of sources).
This is similar with PyOpenGL solution.

The way this got updated from the context is a bit unreliable, and for handlers
the update couldn't happen because there is no context passed in. Now it's
updated from setup_app_data, which is where the change actually happens. I left
in the other updates to be sure but they should not be needed anymore.
