As one of the persons responsible for creating ReplicantBody (I supervised
the project, and have done some additions afterwards) I really would like to
see HW skinning in ReplicantBody.
I suggested a while back that a merge between osgCal and rbody would
probably be beneficial to all users of CA in osg.
I didnt get any real feedback then, perhaps the time has come?
The rendering in rbody can surely be done in a more efficient way, but at
the time there wasnt even support for GLSL in osg, so we figured that it
would take us too long to do that.
With that said, we dont currently have any active projects using rbody, but
I do would like it to live a happy life and prosper...
So if someone is willing to put in an effort I can surely grant them write
access to the svn repository!!
We will most certainly use it in the future, but right now we dont have a
budget for further development.

Hi masters of characters,
I' m a newbie in character animation, but would like to add some simple
avatar-animations to our applications.
We do not have any commercial plan, so GPL licensing is ok.
It seems there are a lot of projects, none of them fully supported. (I'
ve also found osgCharacter at
www.openscenegraph.com/osgwiki/pmwiki.php/NodeKits/OsgCharacter)
We would like some suggestion to which library to start studying.
Our requirements:
1) it should work with latest SVN
2)it should work under windows
Nice things to have
3)Tutorial (ease of use) and some viable path to export content from MAX
(or Blender)
4)it should support not only humans but also different skeletons
5)ihardware skinning
6)nodekit / plugin wrapping, so to being a ble to treat animated
characters as other osg /ive files
7)some form of LOD support (when a character is far awy shoul consume
less draw / update time)
Any suggestion?
From a "user" perspective, it would be really nice to see developer
join force on one common projects instead seeing multiple efforts.
Anyway... many compliments and thanks anyway to all of you
Thanks in advance

It seem you have developed really intersting things.... let us know if
you decide to release your code
