Struct ark_api::Conformal3

pub struct Conformal3 { /* private fields */ }

Represents a transform with translation + rotation + uniform scale. Preserves local angles. Scale and rotation will be applied first, then translation.

Implementations

impl Conformal3

pub const IDENTITY: Conformal3 = Self{ translation_and_scale: Vec4::W, rotation: Quat::IDENTITY,}

The identity transform: doesn’t transform at all. Like multiplying with 1.

pub fn from_scale_rotation_translation(
    scale: f32,
    rotation: Quat,
    translation: Vec3
) -> Conformal3

A transform that first rotates and scales around the origin and then moves all points by a set amount.

Equivalent to Conformal3::from_translation(translation) * (Conformal3::from_scale(rotation) * Conformal3::from_quat(scale)).

The given rotation should be normalized.

pub fn from_rotation_translation(rotation: Quat, translation: Vec3) -> Conformal3

A transform that first rotates around the origin and then moves all points by a set amount.

Equivalent to Conformal3::from_translation(translation) * Conformal3::from_quat(rotation).

The given rotation should be normalized.

pub fn from_translation(translation: Vec3) -> Conformal3

A pure translation without any rotation or scale.

pub fn to_scale_rotation_translation(&self) -> (f32, Quat, Vec3)

Returns this transform decomposed into scale, rotation, translation

pub fn from_quat(rotation: Quat) -> Conformal3

A pure rotation without any translation or scale.

pub fn from_scale(scale: f32) -> Conformal3

A pure scale without any translation or rotation.

pub fn inverse(&self) -> Conformal3

Returns the inverse of this transform. my_transform * my_transform.inverse() = Conformal3::IDENITTY

pub fn from_affine3a_lossy(transform: &Affine3A) -> Conformal3

Will attempt to create a Conformal3 from an Affine3A. Assumes no shearing and uniform scaling. If the affine transform contains shearing or non-uniform scaling it will be lost.

pub fn to_affine3a(&self) -> Affine3A

Returns this transform as an Affine3A

pub fn to_mat4(self) -> Mat4

Returns this transform as a Mat4

pub fn transform_point3(&self, value: Vec3) -> Vec3

Transform a Vec3 using translation, rotation, scale.

pub fn transform_vector3(&self, value: Vec3) -> Vec3

Transform a Vec3 using only rotation and scale.

pub fn rotation(&self) -> Quat

Returns the rotation

pub fn set_rotation(&mut self, rotation: Quat)

Sets the rotation

pub fn translation(&self) -> Vec3

Returns the translation

pub fn translation_and_scale(&self) -> Vec4

Returns the translation and scale as a Vec4

pub fn set_translation(&mut self, translation: Vec3)

Sets the translation

pub fn scale(&self) -> f32

Returns the scale

pub fn set_scale(&mut self, scale: f32)

Sets the scale

pub fn from_iso_transform(t: IsoTransform) -> Conformal3

Builds a Conformal3 from an IsoTransform (rotation, translation).

pub fn look_at_rh(eye: Vec3, target: Vec3, up: Vec3) -> Option<Conformal3>

Creates a right-handed view transform using a camera position, a point to look at, and an up direction.

The result transforms from world coordinates to view coordinates.

For a view coordinate system with +X=right, +Y=up and +Z=back.

Will return None if any argument is zero, non-finite, or if forward and up are colinear.

pub fn is_finite(&self) -> bool

Returns true if, and only if, all components are finite.

If any component is either NaN, positive or negative infinity, this will return false.
