Thanks for your advice, Campbell :) I think at this stage I will try to tackle from Python scripting first (the templates are really helpful) and get reference from the existing source codes handling input devices to find a way to communicate between Blender and the external system I tried to build. > Date: Thu, 23 Sep 2010 14:47:48 +0400 > From: Sergey Kurdakov <[email protected]> > Hi Anthony, > > >on creating a new interface that can > >translate the real-life actions into 3D coordinates. > > You could be interested in this project - > http://forge.lifl.fr/PIRVI/wiki/MTUtils/blenderTUIO it > adds 3D input from > screen, the code is on the site - so you might look at what > they changed. > > Regards > Sergey Wow... that's a nice reference.
