Implementations

impl<N: Copy + RealField> Frame<N>

pub fn look_at(target: Point3<N>, eye: &Point3<N>, up: &Vector3<N>) -> Self

Sets eye position inclusive its roll attitude and target position in world space.

pub fn eye(&self) -> Point3<N>

Eye position in world space.

pub fn set_eye(&mut self, eye: &Point3<N>, up: &Vector3<N>)

Sets eye position inclusive its roll attitude in world space preserving target position.

pub fn target(&self) -> &Point3<N>

Target position in world space.

pub fn set_target(&mut self, target: Point3<N>)

Sets target position in world space preserving eye position inclusive its roll attitude.

pub fn distance(&self) -> N

Distance between eye and target.

pub fn set_distance(&mut self, zat: N)

Sets distance between eye and target preserving target position.

pub fn scale(&mut self, rat: N)

Scales distance between eye and target by ratio preserving target position.

pub fn local_scale_around(&mut self, rat: N, pos: &Point3<N>)

Scales distance between eye and point in camera space by ratio preserving target position.

pub fn scale_around(&mut self, rat: N, pos: &Point3<N>)

Scales distance between eye and point in world space by ratio preserving target position.

pub fn local_slide(&mut self, vec: &Vector3<N>)

Slides camera eye and target by vector in camera space.

pub fn slide(&mut self, vec: &Vector3<N>)

Slides camera eye and target by vector in world space.

pub fn local_orbit(&mut self, rot: &UnitQuaternion<N>)

Orbits eye by rotation in camera space around target.

pub fn local_orbit_around(&mut self, rot: &UnitQuaternion<N>, pos: &Point3<N>)

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

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

Orbits eye by rotation in world space around target.

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

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>>)

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>>

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

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

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

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

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

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

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

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

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

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

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

pub fn angles(&self) -> (N, N, N)

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

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

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>

View transformation from world to camera space.
