Struct Segment3f 

pub struct Segment3f {
    pub start: Vec3f,
    pub end: Vec3f,
}

Line segment between two points

Fields

start: Vec3f

end: Vec3f

Implementations

impl Segment3f

pub fn new(start: Vec3f, end: Vec3f) -> Segment3f

Create a segment between two points

pub fn to_vec3f(self) -> Vec3f

Get vector from start to end (not normalized)

pub fn length(self) -> f32

Length of the line segment

pub fn reversed(self) -> Segment3f

Create a copy of self with endpoints reversed.

pub fn distance_to_parametric_delta(self, distance: f32) -> f32

Convert a distance in coordinate space to a distance in the line segment’s parametric space. The sign of the input is kept.

pub fn distance_from_parametric_delta(self, delta: f32) -> f32

Convert a parametric delta to coordinate space. The sign of the input is kept.

pub fn point_from_parametric(self, t: f32) -> Vec3f

Linearly interpolate between the segment’s endpoints by the factor t. When t is zero the result is self.start, and when t is one the result is self.end. The range of t is not clamped.

pub fn segment_from_parametric_range(self, r: Rangef) -> Segment3f

Treat the range’s start and end as parametric coords. Use point_from_parametric to interpolate the range into a new segment. The output segment is not clamped.

pub fn project_segment_as_range(self, other: Segment3f) -> Rangef

Project another segment onto self. The result is a parametric range of self clamped to [0, 1].

pub fn point_distance_squared(self, point: Vec3f) -> f32

Return the squared distance from this segment to the input point.

pub fn point_distance(self, point: Vec3f) -> f32

Return the distance from this segment to the input point.

pub fn closest_point_to_point(self, point: Vec3f) -> (f32, Vec3f)

Find the point on the segment closest to the input point. The return value contains both the parametric and actual location of the closest point.

Trait Implementations

impl Add<Vec3f> for Segment3f

type Output = Segment3f

The resulting type after applying the + operator.

fn add(self, v: Vec3f) -> Self::Output

Performs the + operation.

impl Clone for Segment3f

fn clone(&self) -> Segment3f

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Segment3f

impl Debug for Segment3f

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Segment3f

fn eq(&self, other: &Segment3f) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
