Jannik, you were right .. Here is the thing (bellow) .. Thanks a bunch for
the pointer !!
inline void RadialShooter::shoot(Particle* P) const
{
float theta = _theta_range.get_random();
float phi = _phi_range.get_random();
float speed = _speed_range.get_random();
osg::Vec3 rot_speed = _rot_speed_range.get_random();
P->setVelocity(osg::Vec3(
speed * sinf(theta) * cosf(phi),
speed * sinf(theta) * sinf(phi),
speed * cosf(theta)
));
P->setAngularVelocity(rot_speed);
}
