}

The group of affine transformations. They are decomposable into a rotation, a non-uniform scaling, a second rotation, and a translation (applied in that order).

Associated Types

type Rotation: Rotation<E>[src]

Type of the first rotation to be applied.

type NonUniformScaling: AffineTransformation<E>[src]

Type of the non-uniform scaling to be applied.

type Translation: Translation<E>[src]

The type of the pure translation part of this affine transformation.

Required methods

fn decompose(
    &self
) -> (Self::Translation, Self::Rotation, Self::NonUniformScaling, Self::Rotation)[src]

Decomposes this affine transformation into a rotation followed by a non-uniform scaling, followed by a rotation, followed by a translation.

fn append_translation(&self, t: &Self::Translation) -> Self[src]

Appends a translation to this similarity.

fn prepend_translation(&self, t: &Self::Translation) -> Self[src]

Prepends a translation to this similarity.

fn append_rotation(&self, r: &Self::Rotation) -> Self[src]

Appends a rotation to this similarity.

fn prepend_rotation(&self, r: &Self::Rotation) -> Self[src]

Prepends a rotation to this similarity.

fn append_scaling(&self, s: &Self::NonUniformScaling) -> Self[src]

Appends a scaling factor to this similarity.

fn prepend_scaling(&self, s: &Self::NonUniformScaling) -> Self[src]

Prepends a scaling factor to this similarity.

Provided methods

fn append_rotation_wrt_point(&self, r: &Self::Rotation, p: &E) -> Option<Self>[src]

Appends to this similarity a rotation centered at the point p, i.e., this point is left invariant.

May return None if Self does not have enough translational degree of liberty to perform this computation.
