Struct nblast::PointsTangentsAlphas

pub struct PointsTangentsAlphas { /* private fields */ }

Minimal struct to use as the query (not the target) of an NBLAST comparison. Equivalent to “dotprops” in the reference implementation.

Implementations

impl PointsTangentsAlphas

pub fn new(points: Vec<Point3>, tangents_alphas: Vec<TangentAlpha>) -> Self

Trait Implementations

impl Clone for PointsTangentsAlphas

fn clone(&self) -> PointsTangentsAlphas

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl NblastNeuron for PointsTangentsAlphas

fn len(&self) -> usize

Number of points in the neuron.

fn points(&self) -> impl Iterator<Item = Point3> + '_

Return an owned copy of the points present in the neuron. The order is not guaranteed, but is consistent with tangents.

fn centroid(&self) -> Point3

fn tangents(&self) -> impl Iterator<Item = Normal3> + '_

Return an owned copy of the unit tangents present in the neuron. The order is not guaranteed, but is consistent with points.

fn alphas(&self) -> impl Iterator<Item = Precision> + '_

Return an owned copy of the alpha values for points in the neuron. The order is consistent with points and tangents.

fn is_empty(&self) -> bool

Whether the number of points is 0.

impl QueryNeuron for PointsTangentsAlphas

fn query_dist_dots<'a>( &'a self, target: &'a impl TargetNeuron, use_alpha: bool ) -> impl Iterator<Item = DistDot> + 'a

Calculate the distance and (alpha-scaled) absolute dot products for point matches between this and a target neuron.

fn query( &self, target: &impl TargetNeuron, use_alpha: bool, score_calc: &ScoreCalc ) -> Precision

Calculate the raw NBLAST score by comparing this neuron to the given target neuron, using the given score function. The score function is applied to each point match distance and summed.

fn self_hit(&self, score_calc: &ScoreCalc, use_alpha: bool) -> Precision

The raw NBLAST score if this neuron was compared with itself using the given score function. Used for normalisation.
