A trait representing an affine transformation that can be applied to points or vectors. An affine transformation is one which

Required Methods

`fn one() -> Self`

Create an identity transformation. That is, a transformation which does nothing.

`fn look_at(eye: P, center: P, up: P::Diff) -> Self`

Create a transformation that rotates a vector to look at center from eye, using up for orientation.

`fn transform_vector(&self, vec: P::Diff) -> P::Diff`

Transform a vector using this transform.

`fn transform_point(&self, point: P) -> P`

Transform a point using this transform.

`fn concat(&self, other: &Self) -> Self`

Combine this transform with another, yielding a new transformation which has the effects of both.

`fn inverse_transform(&self) -> Option<Self>`

Create a transform that "un-does" this one.

Provided Methods

`fn concat_self(&mut self, other: &Self)`

Combine this transform with another, in-place.
