The w property of the Rotation struct represents the W component of the rotation. This component is part of the quaternion representation of the rotation, which includes the X, Y, Z, and W components. The W component specifically represents the rotation around the normal defined by the X, Y, and Z components.
Use the w property to access or modify the W component of a Rotation instance. This is useful when you need to work directly with the quaternion representation of a rotation, such as when performing complex mathematical operations or interfacing with systems that require quaternion inputs.
// Example of accessing the W component of a Rotation Rotation rotation = new Rotation(); float wComponent = rotation.w; // Example of setting the W component of a Rotation rotation.w = 0.5f;
