Re: [Bf-committers] A resources help for paper (Farsthary)
Hi Raul, I bet we are on the same deadline. I don't know many things about sculpting, but I believe you should probably mention automatic quadrangulation methods if you are subdividing using Catmull Clark, since the straightforward approach to me would be to deal with triangle meshes and then quadrangulate the result. Last year the cutting edge was Mixed integer quadrangulations, Quadcover is older but still in use, and last year at siggraph there were two papers, one called something like Wave based quadrangulations and the other one called Lp Centroidal Voronoi Tesselations (also dealing with volumic meshing). About sculpting I remember some work about virtual clay modeling and swirling sweepers about volume preservation, but it's a bit old, and might be obsolete. Typing this on scholar provides some results maybe checkout this, the page mentions papers citing it which might be more in the mood: http://portal.acm.org/citation.cfm?id=364338.364395. It's too bad citeseer is currently down. If you are dealing with multiresolution meshes, this should also be part of the related work, I'm not aware of this field to provide up to date references, sorry.

[Bf-committers] blender25 and ctypes-pygtk
I managed to get GTK to work pretty well with blender25 using ctypes. The old PyGTK bindings didn't work that well with blender2.4x because the GTK mainloop did not release the GIL, and there was no ideal way to iterate the main loop from blender. Thankfully ctypes releases the GIL, so threading works! Not sure if updating blender data from a GTK thread can cause a crash, but with this simple addon that changes the scale of the selected object everything is ok so far.more details and source code here:http://pyppet.blogspot.com/2011/01/ctypes-pygtk-in-blender25.html -brett ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers

Hi :) Hi Raul, I bet we are on the same deadline. I don't know many things about sculpting, but I believe you should probably mention automatic quadrangulation methods if you are subdividing using Catmull Clark, Oh yes :) ! I´m aiming at SIGGRAPH 2011 , perhaps is too high goal for me but I think I´m ready to take the chance :) The good thing about the algorithm I´m developing is that it is relatively independent from the subdivision scheme used, so the simpler, the faster to calculate and for several architectural decitions I´m enforcing triangles only. (you will understand why sculptris use triangles only too ;) ) so I end up using Loop subdivision scheme. since the straightforward approach to me would be to deal with triangle meshes and then quadrangulate the result. Last year the cutting edge was Mixed integer quadrangulations, Quadcover is older but still in use, and last year at siggraph there were two papers, one called something like Wave based quadrangulations and the other one called Lp Centroidal Voronoi Tesselations (also dealing with volumic meshing). Definately Centriodal Voronoi Tessellations are an appealing remeshing/relaxation algorithm and I have being tempted to put my hands on it, but I don´t know the status of the quad remeshing GSOC and I don´t want to overlap with that cool project, perhaps in the future, when Unlimited Clay is fleshed out I could extend its relaxation scheme to include it, it will be fun ;) About sculpting I remember some work about virtual clay modeling and swirling sweepers about volume preservation, but it's a bit old, and might be obsolete.

Re: [Bf-committers] Fwd: Copyright violation distributing faac binaries together with GPL software
Ton, libavcodec *is* FFmpeg. (Or part of it, anyway.) The problem that is claimed is that libfaac is included in Blender's version of libavcodec that is distributed with Blender 2.49. The solution is to compile FFmpeg / libavcodec without libfaac. (Throwing out x264 is not an option, as libfaac has more problems than just being GPL-incompatible) It should be a build config change and that's it - but someone has to build a new distribution. Then we should be OK. SVN is down fot the moment, so I haven't been able to look at the 2.49 source to figure out where the change needs to be made. We lose the ability to encode sound using AAC, but nothing more. Could you run this past Carl Hoyos and see if I got this thing right? See here for some others who have run into the same issue: https://bugs.launchpad.net/ubuntu/+source/faac/+bug/374900 http://lists.rpmfusion.org/pipermail/rpmfusion-developers/2009-October/006221.html Also look here for a libfaac license change (?): http://faac.cvs.sourceforge.net/viewvc/faac/faac/libfaac/tns.c?r1=1.8r2=1.9 Here's the libfaac license, for reference: BEGIN LIBFAAC LICENCE __ COPYRIGHTS FAAC is based on the ISO MPEG-4 reference code.

[Bf-committers] Release done, next steps!
Hi everyone, Thanks for the builds! Looks like we got a good one here :) The bug tracker is still nice low, so we can move on to the pending todo items. We should also try to get our patch tracker clean, to have compliant patches applied, and the rest at least categorized and shortly reviewed. We also need several im/exporters brought back still. To me it seems current svn is already quite stable, a next release - provided todo got cleaned up - can definitely be out of beta then. Short term roadmap prediction: - March: 2.57 release (with at least a week an RC for test) Being our 'first' 2.5 official release, it could align with a make- over of blender.org! - April/May: 2.58 as final for the 2.5 project (based on 2.57 feedback?) In May we then can move svn to 2.60, and start merging it with at the urgent waiting branches; - render branch (sintel) - bmesh (how's it going?) - GSoC projects, like rigid body anim During the next months the branch devs can report here on how stable migrations are, to make a planning that doesn't break 2.6 immediately, but do this in smaller steps and releases. I then would also like to start the recode for our shader system (in branch at first) And will have to wrap up the python api, especially for UI customizing and render api.

+1 for an option of mass-creating objects. I have ported a script for
2.4x to 2.5x that creates thousands of objects and it's wy slower
now.
It would be nice if scene.objects.link() accepts a list of objects and
then updates the depgraph at the end.

If your making multiple duplicates through python, would an operator
option to duplicate many times help?, then the update would only be
once at the end.
I'd prefer not to allow this, since its a workaround and seems
arbitrary to add these kinds of options as users find certain
operators slow.
Id rather have a testcase showing slow duplication, then profile this
and see whats taking time.
While this probably isn't a quick fix, there are places where
OB_RECALC_TIME OB_RECALC_DATA are used in blender were I'm fairly
sure they don't need to be.

Hi Campbell, nice function.
Could the OBJECT_OT_duplicate operator have a (HIDDEN) option to skip

(API-wise, not codewise) but maybe could be pushed into Blender.
Now (? not sure since when) that we can force depsgraph sorting and flushing
through python it seems more compatible with the current API design.
Thanks,

also changed how update flags work.

So they use a cube, set non-renderable, switch on the axis display and use this as object input. Maybe it is not worth implementing the rotation and tell people to use a object?

Re: [Bf-committers] how update all?
Hi,
ideasma...@gmail.com (2011-01-06 at 0446.58 +):
Existing files can also botch svn updating (highly annoying for
automatic updates), or when going back in svn history *.pyc files can
stop directories getting removed.
On *nix you can ensure a clean checkout with this:
svn status --no-ignore | grep ^I | awk '{print $2}' | xargs rm -rf
Answer from cdhowie:
http://stackoverflow.com/questions/4515586/clean-an-svn-checkout-remove-non-svn-files
That command is troublesome when filenames have spaces, and only
deletes actively ignored files anyway (some of which you would like to
keep, like source search caches), but not local modifications or
unversioned files which is part of what was asked for. The best is
probably a combination of svn-clean and svn revert... or just svn
checkout (slow but only way to make sure).

Re: [Bf-committers] Fwd: Copyright violation distributing faac binaries together with GPL software
Carl and everyone else, I've done some checking of the FFmpeg integration in Blender 2.49b. I came up with the following: I can confirm that the default configuration for compiling FFmpeg into Blender has --enable-gpl set and no --enable-nonfree. So it *ought* to be all right. It is linked against libfaad, but I find no trace of libfaac in the dll. For example, the string faac: codec init failed is in the dll, but that's from libfaad (libfaad.c), which does not link to libfaac, as far as I know. In libfaac.c, the FFmpeg interface to libfaac, are the strings wrong libfaac version and libfaac AAC (Advanced Audio Codec), neither of which can be found in avcodec-52.dll. Unless these strings are stored somewhere else, shouldn't they be present if libfaac.o is linked in? I am really unfamiliar with the FFmpeg codebase, so I don't know what the significance of the above is. Carl, could you give me some guidance as to what to look for to confirm the existence / absence of libfaac code in the dll?

Re: [Bf-committers] Fwd: Copyright violation distributing faac binaries together with GPL software
No probs, dude. Regarding the 2.56 version - right now we have a libavcodec dll binary checked into SVN - there is no source code in the blender tree: https://svn.blender.org/svnroot/bf-blender/trunk/lib/windows/ffmpeg/lib/ (We have ffmpeg binaries for other platforms checked in as well) I think it would be trivial to get a source package checked in there as well. The corresponding source tarball is here: http://ffmpeg.arrozcru.org/autobuilds/ffmpeg/sources/ffmpeg-r22941-swscale-r31050.tar.bz2 I don't have commit access, so I'm leaving this to someone who does now.

Your analysis is absolutely correct, given that I am the one hunting real FFmpeg license violators, I should really know better! libavcodec.dll shipped with Blender 2.49b was NOT linked against libfaac, there is absolutely nothing wrong with the dll (license-wise, since it is quite old, I fear there are a few known bugs in it)! Note that there may be another problem, http://download.blender.org/release//Blender2.56abeta/blender-2.56a-beta-windows32.zip contains libavcodec, but the source package http://download.blender.org/source/blender-2.56-beta.tar.gz may be missing FFmpeg sources (probably because you removed FFmpeg from your source tree, iiuc), Am I right or am I again missing something? Thank you for reacting so quickly (I wish the real license violators would be so fast!), and please excuse me again for making wrong assumptions! Carl Eugen PS: The reason I went to your forum today (and believed I saw the wrong information there that Blender uses libfaac) is this bug report that claims a problem using libavcodec: http://roundup.ffmpeg.org/issue2485 If anybody knows which posts in the blender's bugtracker user chaos means, I can try to help (although I am very bad in using libavcodec outside of FFmpeg/MPlayer).

[Bf-committers] building blender with clang, scan-build
Building blender with clang's scan-build gives useful reports/warnings which typical compilers wont report. of course it has a lot of false positives or warnings which wouldn't result in actual bugs but its it also shows up real bugs, some of which would be hard to track otherwise. Heres the output from scan-build as html (r34117): http://www.graphicall.org/ftp/ideasman42/2011-01-07-2/ I wrote up a wiki page on how to build llvm+clang and use with blender. http://wiki.blender.org/index.php/User:Ideasman42/BlenderClang -- - Campbell ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers

(Throwing out x264 is not an option, as libfaac has more problems than just being GPL-incompatible) It should be a build config change and that's it - but someone has to build a new distribution. Then we should be OK. SVN is down fot the moment, so I haven't been able to look at the 2.49 source to figure out where the change needs to be made. We lose the ability to encode sound using AAC, but nothing more. FFMPEG has their own AAC decoder which should work for the decode side. They have been developing their own AAC encoder as well, but it's still a work in progress. I've always built against my system's ffmpeg (0.6.1+) without any issues.
