rotation

Extracts and returns the rotation-only Mat4 from m by normalizing its basis vectors.

fun rotation(d: Float3, order: RotationsOrder = RotationsOrder.ZYX): Mat4

Returns a rotation Mat4 from Euler angles (in degrees) in the specified order.

the rotation matrix

per-axis Euler angles in degrees

order

the rotation order; defaults to RotationsOrder.ZYX

fun rotation(yaw: Float = 0.0f, pitch: Float = 0.0f, roll: Float = 0.0f, order: RotationsOrder = RotationsOrder.ZYX): Mat4

Returns a rotation Mat4 from individual Euler angles in radians in the specified order.

roll

rotation around the third axis in radians

order

the rotation order; defaults to RotationsOrder.ZYX

Returns a rotation Mat4 around axis by angle degrees.

the rotation matrix

axis

the rotation axis (need not be normalized)

angle

the rotation angle in degrees

Returns a rotation Mat4 from the given quaternion (normalized internally).
