pub fn orbit(&mut self, rot: &UnitQuaternion<N>)[src]

Orbits eye by rotation in world space around target.

pub fn orbit_around(&mut self, rot: &UnitQuaternion<N>, pos: &Point3<N>)[src]

Orbits eye by rotation in world space around point in world space.

pub fn look_around(&mut self, pitch: N, yaw: N, yaw_axis: &Unit<Vector3<N>>)[src]

Orbits target around eye by pitch and yaw preserving roll attitude aka first person view.

Use fixed Self::yaw_axis() by capturing it when entering first person view.

pub fn local_pitch_axis(&self) -> Unit<Vector3<N>>[src]

Positive x-axis in camera space pointing from left to right.

pub fn local_yaw_axis(&self) -> Unit<Vector3<N>>[src]

Positive y-axis in camera space pointing from bottom to top.

pub fn local_roll_axis(&self) -> Unit<Vector3<N>>[src]

Positive z-axis in camera space pointing from back to front.

pub fn pitch_axis(&self) -> Unit<Vector3<N>>[src]

Positive x-axis in world space pointing from left to right.

pub fn yaw_axis(&self) -> Unit<Vector3<N>>[src]

Positive y-axis in world space pointing from bottom to top.

pub fn roll_axis(&self) -> Unit<Vector3<N>>[src]

Positive z-axis in world space pointing from back to front.

pub fn angles(&self) -> (N, N, N)[src]

Eye attitude via intrinsic (pitch, yaw, roll) angles, see Self::set_angles().

pub fn set_angles(&mut self, pitch: N, yaw: N, roll: N)[src]

Sets eye attitude via intrinsic angles.

Eye rotation occurs in the sense prescribed by the right-hand rule in the following order:

  1. roll about Self::roll_axis() within ±π,
  2. pitch about rolled Self::pitch_axis() within ±π,
  3. yaw about rolled and pitched Self::yaw_axis() within ±π/2.

pub fn view(&self) -> Isometry3<N>[src]

View transformation from world to camera space.
