Implementations§

source§

impl Affine3A

source

pub const ZERO: Affine3A = _

The degenerate zero transform.

This transforms any finite vector and point to zero. The zero transform is non-invertible.

source

pub const IDENTITY: Affine3A = _

The identity transform.

Multiplying a vector with this returns the same vector.

source

pub const NAN: Affine3A = _

All NAN:s.

source

pub const fn from_cols( x_axis: Vec3A, y_axis: Vec3A, z_axis: Vec3A, w_axis: Vec3A ) -> Affine3A

Extracts scale, rotation and translation from self.

Transforms the given 3D points, applying shear, scale, rotation and translation.

source

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

Transforms the given 3D vector, applying shear, scale and rotation (but NOT translation).

To also apply translation, use Self::transform_point3() instead.

source

pub fn transform_point3a(&self, rhs: Vec3A) -> Vec3A

Transforms the given Vec3A, applying shear, scale, rotation and translation.

source

pub fn transform_vector3a(&self, rhs: Vec3A) -> Vec3A

Transforms the given Vec3A, applying shear, scale and rotation (but NOT translation).

To also apply translation, use Self::transform_point3a() instead.

source

pub fn is_finite(&self) -> bool

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

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

source

pub fn is_nan(&self) -> bool

Returns true if any elements are NaN.

source

pub fn abs_diff_eq(&self, rhs: Affine3A, max_abs_diff: f32) -> bool

Returns true if the absolute difference of all elements between self and rhs is less than or equal to max_abs_diff.

This can be used to compare if two 3x4 matrices contain similar elements. It works best when comparing with a known value. The max_abs_diff that should be used used depends on the values being compared against.

For more see comparing floating point numbers.

source

pub fn inverse(&self) -> Affine3A

Return the inverse of this transform.

Note that if the transform is not invertible the result will be invalid.
