Required methods

pub fn one() -> Self

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

pub fn look_at(eye: P, center: P, up: <P as EuclideanSpace>::Diff) -> Self

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

pub fn transform_vector(
    &self,
    vec: <P as EuclideanSpace>::Diff
) -> <P as EuclideanSpace>::Diff

Transform a vector using this transform.

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

Transform a point using this transform.

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

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

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

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