pub struct VoronoiSimplex { /* private fields */ }
Expand description
A simplex of dimension up to 3 that uses Voronoï regions for computing point projections.
Implementations
sourceimpl VoronoiSimplex
impl VoronoiSimplex
sourcepub fn new() -> VoronoiSimplex
pub fn new() -> VoronoiSimplex
Creates a new empty simplex.
sourcepub fn proj_coord(&self, i: usize) -> Real
pub fn proj_coord(&self, i: usize) -> Real
Retrieves the barycentric coordinate associated to the i
-th by the last call to project_origin_and_reduce
.
sourcepub fn prev_proj_coord(&self, i: usize) -> Real
pub fn prev_proj_coord(&self, i: usize) -> Real
Retrieves the barycentric coordinate associated to the i
-th before the last call to project_origin_and_reduce
.
sourcepub fn prev_point(&self, i: usize) -> &CSOPoint
pub fn prev_point(&self, i: usize) -> &CSOPoint
The i-th point of the simplex before the last call to projet_origin_and_reduce
.
sourcepub fn project_origin_and_reduce(&mut self) -> Point<Real>
pub fn project_origin_and_reduce(&mut self) -> Point<Real>
Projets the origin on the boundary of this simplex and reduces self
the smallest subsimplex containing the origin.
Retruns the result of the projection or Point::origin() if the origin lies inside of the simplex.
The state of the samplex before projection is saved, and can be retrieved using the methods prefixed
by prev_
.
sourcepub fn project_origin(&mut self) -> Point<Real>
pub fn project_origin(&mut self) -> Point<Real>
Compute the projection of the origin on the boundary of this simplex.
sourcepub fn contains_point(&self, pt: &Point<Real>) -> bool
pub fn contains_point(&self, pt: &Point<Real>) -> bool
Tests if the given point is already a vertex of this simplex.
sourcepub fn dimension(&self) -> usize
pub fn dimension(&self) -> usize
The dimension of the smallest subspace that can contain this simplex.
sourcepub fn prev_dimension(&self) -> usize
pub fn prev_dimension(&self) -> usize
The dimension of the simplex before the last call to project_origin_and_reduce
.
sourcepub fn max_sq_len(&self) -> Real
pub fn max_sq_len(&self) -> Real
The maximum squared length of the vertices of this simplex.
sourcepub fn modify_pnts(&mut self, f: &dyn Fn(&mut CSOPoint))
pub fn modify_pnts(&mut self, f: &dyn Fn(&mut CSOPoint))
Apply a function to all the vertices of this simplex.
