Hi everybody
Im trying to superimose qt.movie containig alpha channel over video input. Part of this alpha channel is semitransparent:

gemhead
|
pix_film
|
pix_texture
|
alpha
|
rectangle

Each time, checking different codecs I receive blackish ugly outline around mask, and part with semitransparen alpha has black dominant: in video editing software are 2 types of alpha mixing - subtractive, and additive. Alpha can be premultiplied with black, and using aditive one can remove this black component when layering. How I can get rid of this unwanted outline, maintaining semitransparent part?

Hi kinolab, here interesting news for you:
As a gift for the beginning of 2011, there's a new "unstable" version
of OpenNI & Sensor modules with MacOSX support!

Other new features:
* Added support for multiple sensors.
* Improved README! (much more detailed instructions...)
* Some bug fixes...

Previous version features:
* A brand new .NET wrapper and .NET samples (OpenNI.net).

NITE binaries for all supported platforms (including MacOSX) will also
be released very soon.

And thanks for everyone that's helped.

Maybe someone will write something like jmpelletier Jitter external that uses the libfreenect library to grab frames from a Kinect device? and for pc as well. To difficult for me
G.

yes, openni usertracker and OSCeleton- https://github.com/Sensebloom/OSCeleton
are for pc. there is very good Mac driver https://github.com/jmpelletier/jit.freenect.grab, working with max/msp, and some patches as well.Unfortuately, I have pc...
Greg

Hi, PC user can try https://github.com/Sensebloom/OSCeleton with OpenNi usertracker.exe. OSCeleton send messages on port 7110, using udpreceive you can play with kinect sceleton data. Wonderfull!!

hi, thanks for reply!
I will try webcam and collision detection tomorrow. Btw, in your earlier post you mention Max scripts converting animations to GEM engine format. Will you post them as well? I'm doing interactive 3d visualisation for my exhibition. I thought of using blender, but your patch will be much better for this. I plan to control camera motion with wii motion plus, which can be easily linked with pd.
Love your patch, Sonsofsol!

Hi everybody, it's my first post here!
Very good patch Sonsofsol!!!
Thanks for sharing with others.
Some small ( I hope) bugs: pd reports error ( win pc) :
zexy-2.2.3 (compiled: Sep 22 2010)
Copyright (l) 1999-2008 IOhannes m zmölnig, forum::für::umläute & IEM
error: pack: b: bad type
another :
error: pd-uzi.pd: no such object
when launching from c:/gem-engine, besides this two bugs, everything works, but it is not possible to launch examples from inside c:/Program Files /pd/extra/!!!new/gem-engine/ .
Is it possible to add colission detection to camera in cursor mode, and live (webcam) backgorund? Would be great...
