Unity 3d rotate vector by quaternion. If a negative value is used for maxradiansdelta the vector will rotate away from target until it is pointing in exactly the opposite direction then stops. By specifying euler interpolation you are telling unity that you want the full range of motion specified by the angles. The vector that defines in which direction up is.

For more information see rotation and orientation in unity. Quaternion rotation quaternion euler rotationvector. And thank you for taking the time to help us improve the quality of unity documentation.

You can easily rotate a direction vector by calling. With quaternion rotation however you are saying you simply want the rotation to end at a particular orientation and unity uses quaternion interpolation and rotate across the shortest distance to get there. If the magnitudes of current and target are different then the magnitude of the result will be linearly interpolated during the rotation.

Negative values of maxdegreesdelta will move away from to until the rotation is exactly the opposite direction. Then you do the quaternion multiplications to get v and then extract the ijk components again. The direction to look in.

As for the multiplication with a vector you just extend the vector to a quaternion by setting a quat s real component to zero and its ijk components to the vector s xyz. And thank you for taking the time to help us improve the quality of unity documentation. Rotates a rotation from towards to.

The from quaternion is rotated towards to by an angular step of maxdegreesdelta but note that the rotation will not overshoot. The real part of v should always come out zero plus or minus some floating point error. You can use the quaternion operator to rotate one rotation by another or to rotate a vector by a rotation.

If you pass a zero vector into translation and a one vector into scale and just set the rotation to the desired rotations like this.

Note that unity expects quaternions to be normalized. Within unity s own animation window there are options which allow you to specify how the rotation should be interpolated using quaternion or euler interpolation. Creates a rotation which rotates angle degrees around axis.
