[osg-users] Quat normalization

Hi all, I just have a little question, because I'm not sure of something about quat : I have to quat q1 and q2 To pass form q1 to q2 I've made q = q1.inverse()*q2 But even if the result angle looks correct... the vector or rotation looks very little : vec : 2.71051e-020, -2.71051e-020,

Re: [osg-users] Quat normalization

Hi First, yes it is the vector OF rotation, sorry for the mistake... And when I speak about normalizing, I'm just thinking of making a vector.normalize()... with that operation, length of the vector will be 1, even if the vector is close to 0 0 0... I just want to use this vector to set the

Re: [osg-users] Quat normalization

Thanks a lot, I'll try to normailize it, because epsilon is not very little in my application, so this could make zero-rotation Thanks :) Vincent. 2008/3/19, J.P. Delport [EMAIL PROTECTED]: Hi, the code from makeRotate explains it best: --8-- void Quat::makeRotate( value_type angle,

Re: [osg-users] Quat normalization

Hi, the code from makeRotate explains it best: --8-- void Quat::makeRotate( value_type angle, value_type x, value_type y, value_type z ) { const value_type epsilon = 0.001; value_type length = sqrt( x*x + y*y + z*z ); if (length epsilon) { // ~zero length
