osg.
Quat
¶ Represents: c++ class Wraps: osg::Quat A quaternion class. It can be used to represent an orientation in 3D space. There a numbers a getters/setters to control values of each quaternion’s components (e.g. getter
osg.Quat.y()
and setter with the same name with value to set etc.).Constructors:

makeRotate
(osg.Vec3 vec1, osg.Vec3 vec2) Make a rotation
osg.Quat
which will rotate vec1 to vec2. Generally take a dot product to get the angle between these and then use a cross product to get the rotation axis Watch out for the two special cases when the vectors are co-incident or opposite in direction.Параметры:
