pub struct Rotation3<N> {
    // some fields omitted

Three dimensional rotation matrix.

Methods

impl<N: BaseFloat> Rotation3<N>

fn new(axisangle: Vector3<N>) -> Rotation3<N>

Builds a 3 dimensional rotation matrix from an axis and an angle.

Arguments

• axisangle - A vector representing the rotation. Its magnitude is the amount of rotation in radian. Its direction is the axis of rotation.

fn from_matrix_unchecked(matrix: Matrix3<N>) -> Rotation3<N>

Builds a rotation matrix from an orthogonal matrix.

fn from_euler_angles(roll: N, pitch: N, yaw: N) -> Rotation3<N>

Creates a new rotation from Euler angles.

The primitive rotations are applied in order: 1 roll − 2 pitch − 3 yaw.

impl<N: BaseFloat> Rotation3<N>

fn new_observer_frame(dir: &Vector3<N>, up: &Vector3<N>) -> Rotation3<N>

Creates a rotation that corresponds to the local frame of an observer standing at the origin and looking toward dir.

It maps the view direction dir to the positive z axis.

Arguments

• dir - The look direction, that is, direction the matrix z axis will be aligned with.
• up - The vertical direction. The only requirement of this parameter is to not be collinear to dir. Non-collinearity is not checked.

fn look_at_rh(dir: &Vector3<N>, up: &Vector3<N>) -> Rotation3<N>

Builds a right-handed look-at view matrix without translation.

This conforms to the common notion of right handed look-at matrix from the computer graphics community.

Arguments

• eye - The eye position.
• target - The target position.
• up - A vector approximately aligned with required the vertical axis. The only requirement of this parameter is to not be collinear to target - eye.

fn look_at_lh(dir: &Vector3<N>, up: &Vector3<N>) -> Rotation3<N>

Builds a left-handed look-at view matrix without translation.

This conforms to the common notion of left handed look-at matrix from the computer graphics community.

Arguments

• eye - The eye position.
• target - The target position.
• up - A vector approximately aligned with required the vertical axis. The only requirement of this parameter is to not be collinear to target - eye.
