Struct Line 

pub struct Line<T: Scalar, V: Vector<T>> {
    pub p: V,
    pub d: V,
    /* private fields */
}

An infinite line in 2D or 3D space.

Defined by a point on the line and a direction vector.

Fields

p: V

Point on the line.

d: V

Direction of the line.

Implementations

impl<T: Scalar, V: Vector<T>> Line<T, V>

pub fn new(p: &V, d: &V, epsilon: T) -> Option<Self>

Creates a new line from a point and direction.

Returns None if the direction is too small.

pub fn from_start_end(s: &V, e: &V, epsilon: T) -> Option<Self>

Creates a line from two points.

The line passes through both points, with direction from s to e.

Returns None if the points are too close.

pub fn closest_point_on_line(&self, p: &V, epsilon: T) -> Option<(T, V)>

Finds the closest point on the line to a given point.

Returns:

• t: Parameter value where the closest point occurs
• Point: The closest point on the line

Returns None if the line direction is too small.

impl<T: FloatScalar, V: FloatVector<T>> Line<T, V>

pub fn normalize(&self, epsilon: T) -> Option<Self>

Returns a line with normalized direction vector.

Returns None if the direction is too small.

Trait Implementations

impl<T: Clone + Scalar, V: Clone + Vector<T>> Clone for Line<T, V>

fn clone(&self) -> Line<T, V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Scalar, V: Debug + Vector<T>> Debug for Line<T, V>

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

Formats the value using the given formatter.

impl<T: Default + Scalar, V: Default + Vector<T>> Default for Line<T, V>

fn default() -> Line<T, V>

Returns the “default value” for a type.

impl<T: Copy + Scalar, V: Copy + Vector<T>> Copy for Line<T, V>
