Struct godot::prelude::Transform3D

#[repr(C)]pub struct Transform3D {
    pub basis: Basis,
    pub origin: Vector3,
}

Expand description

Affine 3D transform (3x4 matrix).

Used for 3D linear transformations. Uses a basis + origin representation.

Expressed as a 3x4 matrix, this transform consists of 3 basis (column) vectors a, b, c as well as an origin o:

[ a.x  b.x  c.x  o.x ]
[ a.y  b.y  c.y  o.y ]
[ a.z  b.z  c.z  o.z ]

Fields§

§basis: Basis

The basis is a matrix containing 3 vectors as its columns. They can be interpreted as the basis vectors of the transformed coordinate system.

§origin: Vector3

The new origin of the transformed coordinate system.

Implementations§

§

impl Transform3D

pub const IDENTITY: Transform3D = _

The identity transform, with no translation, rotation or scaling applied. When applied to other data structures, IDENTITY performs no transformation.

Godot equivalent: Transform3D.IDENTITY

pub const FLIP_X: Transform3D = _

Transform3D with mirroring applied perpendicular to the YZ plane.

Godot equivalent: Transform3D.FLIP_X

pub const FLIP_Y: Transform3D = _

Transform3D with mirroring applied perpendicular to the XZ plane.

Godot equivalent: Transform3D.FLIP_Y

pub const FLIP_Z: Transform3D = _

Transform3D with mirroring applied perpendicular to the XY plane.

Godot equivalent: Transform3D.FLIP_Z

pub const fn new(basis: Basis, origin: Vector3) -> Transform3D

Create a new transform from a Basis and a Vector3.

Godot equivalent: Transform3D(Basis basis, Vector3 origin)

pub const fn from_cols( a: Vector3, b: Vector3, c: Vector3, origin: Vector3, ) -> Transform3D

Create a new transform from 4 matrix-columns.

Godot equivalent: Transform3D(Vector3 x_axis, Vector3 y_axis, Vector3 z_axis, Vector3 origin), see Basis for why it’s changed

pub fn from_projection(proj: &Projection) -> Transform3D

Constructs a Transform3D from a Projection by trimming the last row of the projection matrix.

Godot equivalent: Transform3D(Projection from)

pub fn affine_inverse(&self) -> Transform3D

Returns the inverse of the transform, under the assumption that the transformation is composed of rotation, scaling and translation.

pub fn interpolate_with(&self, other: &Transform3D, weight: f32) -> Transform3D

Returns a transform interpolated between this transform and another by a given weight (on the range of 0.0 to 1.0).

pub fn is_finite(&self) -> bool

Returns true if this transform is finite by calling is_finite on the basis and origin.

pub fn looking_at( &self, target: Vector3, up: Vector3, use_model_front: bool, ) -> Transform3D

Available on since_api="4.1" only.

pub fn orthonormalized(&self) -> Transform3D

Returns the transform with the basis orthogonal (90 degrees), and normalized axis vectors (scale of 1 or -1).

Godot equivalent: Transform3D.orthonormalized()

pub fn rotated(&self, axis: Vector3, angle: f32) -> Transform3D

Returns a copy of the transform rotated by the given angle (in radians). This method is an optimized version of multiplying the given transform X with a corresponding rotation transform R from the left, i.e., R * X. This can be seen as transforming with respect to the global/parent frame.

Godot equivalent: Transform2D.rotated()

pub fn rotated_local(&self, axis: Vector3, angle: f32) -> Transform3D

Returns a copy of the transform rotated by the given angle (in radians). This method is an optimized version of multiplying the given transform X with a corresponding rotation transform R from the right, i.e., X * R. This can be seen as transforming with respect to the local frame.

Godot equivalent: Transform2D.rotated_local()

pub fn scaled(&self, scale: Vector3) -> Transform3D

Returns a copy of the transform scaled by the given scale factor. This method is an optimized version of multiplying the given transform X with a corresponding scaling transform S from the left, i.e., S * X. This can be seen as transforming with respect to the global/parent frame.

Godot equivalent: Transform2D.scaled()

pub fn scaled_local(&self, scale: Vector3) -> Transform3D

Returns a copy of the transform scaled by the given scale factor. This method is an optimized version of multiplying the given transform X with a corresponding scaling transform S from the right, i.e., X * S. This can be seen as transforming with respect to the local frame.

Godot equivalent: Transform2D.scaled_local()

pub fn translated(&self, offset: Vector3) -> Transform3D

Returns a copy of the transform translated by the given offset. This method is an optimized version of multiplying the given transform X with a corresponding translation transform T from the left, i.e., T * X. This can be seen as transforming with respect to the global/parent frame.

Godot equivalent: Transform2D.translated()

pub fn translated_local(&self, offset: Vector3) -> Transform3D

Returns a copy of the transform translated by the given offset. This method is an optimized version of multiplying the given transform X with a corresponding translation transform T from the right, i.e., X * T. This can be seen as transforming with respect to the local frame.

Godot equivalent: Transform2D.translated()
