Hi Alberto, Yes, if I multiply it by C deforms avatar. reedev wrote: > Hi Aitor, > > I don't have a solution (but I am following your work with great > interest!) but maybe the Ogre example on openni.org might give you some > clues.

I do not know why, is to invert the matrix? Code: Ogre::Matrix3 matOri(jointOri.orientation.elements[0],-jointOri.orientation.elements[1],jointOri.orientation.elements[2], -jointOri.orientation.elements[3],jointOri.orientation.elements[4],-jointOri.orientation.elements[5], jointOri.orientation.elements[6],-jointOri.orientation.elements[7],jointOri.orientation.elements[8]); Without any change in the matrix, rotations are fine, but the Z and Y axes are exchanged ... If I try to get the euler angles of the array and create a new one with the Z and Y axes swapped, It makes me a curious thing. Let's say an arm turns well but the other does the opposite. I'll keep doing tests ... thanks for the replies! ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=38115#38115 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
