Quaternion::SetRotationAboutAxis

Defined in: C4Quaternion.h

Sets a quaternion to represent a rotation about a given axis.

Prototype

Quaternion& SetRotationAboutAxis(float angle, const Vector3D& axis);

Parameters

`angle`	The angle of rotation, in radians.
`axis`	The axis about which to rotate. This vector should have unit length.

Description

The SetRotationAboutAxis function replaces the components of a quaternion with those representing the rotation about the axis given by the axis parameter through the angle given by the angle parameter. The resulting quaternion has unit length.
