Expand description
A trait representing an affine transformation that can be applied to points or vectors. An affine transformation is one which
Required Methods§
sourcefn one() -> Self
fn one() -> Self
Create an identity transformation. That is, a transformation which does nothing.
sourcefn look_at(eye: P, center: P, up: P::Diff) -> Self
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.
sourcefn transform_vector(&self, vec: P::Diff) -> P::Diff
fn transform_vector(&self, vec: P::Diff) -> P::Diff
Transform a vector using this transform.
sourcefn transform_point(&self, point: P) -> P
fn transform_point(&self, point: P) -> P
Transform a point using this transform.
sourcefn concat(&self, other: &Self) -> Self
fn concat(&self, other: &Self) -> Self
Combine this transform with another, yielding a new transformation which has the effects of both.
sourcefn inverse_transform(&self) -> Option<Self>
fn inverse_transform(&self) -> Option<Self>
Create a transform that “un-does” this one.
Provided Methods§
sourcefn concat_self(&mut self, other: &Self)
fn concat_self(&mut self, other: &Self)
Combine this transform with another, in-place.
