Rotation ​

Rotation represented as a quaternion

Can be created from euler angles or quaternion components. Use Rotation.slerp() for smooth interpolation between rotations.

Example:

javascript
// From euler angles (radians)
var rot = Rotation(0, Math.PI / 2, 0); // 90° around Y

// From quaternion
var rot = Rotation.quaternion(0, 0.707, 0, 0.707);

// Interpolate between rotations
var mid = Rotation.slerp(rotA, rotB, 0.5);

Properties ​

eulerAngles ​

  • Type: Vector3
  • Euler angles in radians (x, y, z)

quaternion ​

  • Type: Vector4
  • Quaternion components (x, y, z, w)
