Re: [Bf-committers] OS X update to XCode 4 breaks compiling

[Shaul Kedem]

Hi,
 I managed compiling and running blender in xcode 4.

 download cmake 2.8.4 and install it.

 After following the instructions at:
http://wiki.blender.org/index.php/Dev:2.5/Doc/Building_Blender/Mac run
"cmake-gui ../blender/"

 Make sure you create an xcode project.

 CMAKE_CXX_COMPILER should be /usr/bin/c++

 config and generate the project.

 Open the project within xcode4 and choose from the sub projects drop
down "install". press the "build and run" button.

 After this step ends choose "blender" from the dropdown and build and
run. at this stage blender runs on my setup.

 Hi OSX devs,

 Apple's new development update XCode 4 now is available (only when
 you
 pay FIVE dollars!).
 Someone in irc mentioned blender doesn't compile (at all) for it.
 Further, this XCode revision drops compiling for older OSX versions
 (10.4 and 10.5) and the install removes all libs/headers for it.

 Here's a report:

Re: [Bf-committers] GSoC Proposal

[philipp oeser]

in your proposal you mention NITE being open source. cant find the info right 
now (not in front of my computer) but i am pretty sure it is not. they only 
provide a licensce key for free. will dig out the license tomorrow if i can 
find it.

good luck anyways, its a very interesting field to work in.

[Bf-committers] GSoC proposal

[Yousef Hurfoush]

hi all

nice feature but wouldn't it be better to go for an anonymous device type for 
capturing rather than kinect. 
basically for low salary countries like mine paying 650$ to get a double kinect 
is not much of a choice :)

here is sample of a capture software using  an anonymous camera device, they 
use PS3 camera as recommended device and you can use any good quality camera, 
i tried it with two cheap cameras (10$ for each) @ home and it worked very good 
and the software is able to handle about 6 cameras for accuracy.

thanks

[Bf-committers] Towards RC - blenderplayer problem

[Sergey Kurdakov]

Hi Brecht.

OK

I will report later found bugs and their causes, when I track them
 (transparent figure in gameplayer and not in Blender Game mode ) in bug
tracker.
somehow it is not visible ( though I'm almost half a year looking at Blender
code ).
But search will return me where to report bugs, thanks for pointer.

Re: [Bf-committers] Towards RC - blenderplayer problem

[Brecht Van Lommel]

Hi Sergey,

The game player will always draw in texture draw mode, that's
intentional, the other draw modes are intended for testing while
working on the game. There is also no 3d view editor in the game
player.

Unless it's a really serious bug that e.g. causes data loss, this kind
of thing can just be reported in the bug tracker, it's easier to keep
track of it and assign to the right developer that way.

Thanks,
Brecht.

[Bf-committers] Towards RC - blenderplayer problem

[Sergey Kurdakov]

Hi all,

I understand it is better to submit a bug report, but as

 RC nears here is description of the problem, I think - which should not be
in release

Model in Blender (game mode ) and Blenderplayer are shown differently.

Maybe model is 'strange' with strange modifiers, still it might shed light
on possible problems in other cases.

so here is a model

http://www.sim-ai.org/S01a.blend

So far I found one place of difference

source\gameengine\BlenderRoutines\BL_KetsjiEmbedStart.cpp

 ketsjiengine->SetDrawType(v3d->drawtype);
 ketsjiengine->SetCameraZoom(camzoom);

drawtype of v3d  is not set to blenderplayer and this results in different
render output,
but there are more problems.

I look for more - but now you can trace the problem too

Hi,
I'm not a developer or someone who knows about implementing such a project,
but I happened to see a paper from Microsoft about their body tracking
algorithm, which I would assume is the one actually used in the xbox. There
was also a video about it, that I haven't watched.

I hope this helps in some way. :)

[Bf-committers] Blender developer IRC minutes, 27 March 2011

[Sergey Kurdakov]

Hi all,

concerning RC

there is currently a problem ( which I investigate ) - that blenderplayer
and blender do show different results.

So far I found one place -
source\gameengine\BlenderRoutines\BL_KetsjiEmbedStart.cpp

 ketsjiengine->SetDrawType(v3d->drawtype);
 ketsjiengine->SetCameraZoom(camzoom);

drawtype of v3d  is not set to blenderplayer and this results in different
output.

but there are more differences (BlenderPlayer doesn't show parts (maybe due
to they  are marked with 'transparency' check box ) while
blender game mode do show.

So I investigate this and  would report  as soon as I know.

But the question is - is this a problem to be resolved or is it OK that
blenderplayer and blender in game mode show different results?

I can provide example models ( after I consult with designers ) to show
problems in case of any interest to resolve this.

Sergey

[Bf-committers] Blender developer IRC minutes, 27 March 2011

[Ton Roosendaal]

Hi all,

1) 2.5x project, 2.57 release

- Ton mentioned he added code to prevent 3d window to redraw during  
initialize render stage. Someone reported a drawing glitch for this,  
needs to be confirmed and pinned down.

- Keymaps save/load (or assign/unassign) has open issues, especially  
for the Maya keymap. Martin Poirier will check on it.

- RC0 test builds are here: http://download.blender.org/release/Blender2.57/

- Linux RC0 64 bits has bad openAL (crashes on ALT+A). Might need an  
updated chroot? Campbell and Sergey offered help to check.

- Linux script to run software Opengl is currently broken. Campbell or  
one of the release builds could check.

- SOX: blenderplayer.app is not building currently.

- Windows installer is still not back. Caleb Joseph (Dobx) offers help  
here, he will work with Nathan Letwory on it.

- New startup.blend still has to be added, Ton will do asap.

- Planning: call for a RC1 tuesday/wednesday, next sunday review of  
status. Then decide to call for release or another RC2 test.

- Autobuild system: still needs a linux chroot, Sergey will help  
Brecht with it.

- Test files for regression will be updated too.

2) GSoC

- Tomorrow students can apply for the Google Summer of Code.

- Ideas list has been reviewed, updated a bit:
http://wiki.blender.org/index.php/Dev:Ref/GoogleSummerOfCode/2011/Ideas

- Tom Musgrove suggests everyone to make advertisement for GSoC, we  
love to see a lot of submissions!

[Bf-committers] GSoC proposal

[Sergey Kurdakov]

Hi Shuvro,

I believe, that there are could actually many directions in implementing
what I mentioned in previous message.

1)st auto calibrate kinect(s) see available software
http://graphics.cs.msu.ru/en/science/research/calibration/cpp
2)a reconstruct scene from kinect using  http://vimeo.com/21096739 ( diff
here http://www.pasteall.org/20117/diff )
using either Kreilos approach or maybe
http://www.ros.org/wiki/openni/Contests/ROS%203D/RGBD-6D-SLAM approach
2) b fit
generic figures to captured data ( generic figures could be taken from
MakeHuman, I think )
3) estimate motion. see additionally link
http://www.ros.org/wiki/openni/Contests/ROS%203D/Skeleton%20Tracker%20Teleoperation%20Package%20for%20Mobile%20Robot

so
pretty much to do.

but unlike your proposal - it does not rely on patented pending approach
implemented in Nite based code (Extraction of skeletons from 3D maps United
States Patent Application 20110052006 ) and potentially provides much more
reliable
motion data capture.

as for Blender and Nite you may see here
http://www.youtube.com/watch?v=UxIcwuo5Rts it is already tested with
http://www.brekel.com/  tool - which is basically a wrapper around Nite.

I just add some info to think on if the way you describe is really worth
pursuite

[Bf-committers] GSoC proposal

[Sergey Kurdakov]

Hi Shuvro,

I have one thought to share on subject of motion capture

 that while there are a lot of samples now when  kinect allows to get motion
capture data
ex http://www.brekel.com/
- one kinect is very hard to make to produce good animation data.

so, while there are quite a bit examples to use Kinect to make motion
capture - it exibits weakness here and there - captures mostly standing
persons, feet sleeps, etc.

There is another approach though.
To use two kinects.

You might look at Oliver Kreylos

http://idav.ucdavis.edu/~okreylos/ResDev/Kinect/ page and also
http://www.cs.ubc.ca/labs/imager/tr/2009/eltopo/eltopo.html software - then,
I expect, it is possible to reconstruct skeleton at each time frame.


To estimate mesh from Oliver Kreylos  data you might use recently
implemented double contouring  algorithm
see http://vimeo.com/21096739 ( diff here http://www.pasteall.org/20117/diff
 )


this way - it would be possible to capture professional quality motion
capture data and not something with sleeping feet.

as a side note you may look at paper
http://openmesh.org/uploads/media/Hornung_TR10.pdf
while not directly related - it might be of some help in implementing above
mentioned approach.

Sergey
