Struct stroke::line::LineSegment
source · pub struct LineSegment<P> { /* private fields */ }
Expand description
LineSegment defined by a start and an endpoint, evaluatable anywhere inbetween using interpolation parameter t: [0,1] in eval() A LineSegment is equal to a linear Bezier curve, which is why there is no specialized type for that case.
Implementations§
source§impl<P> LineSegment<P>where
P: Point,
impl<P> LineSegment<P>where P: Point,
pub fn new(start: P, end: P) -> Self
pub fn eval(&self, t: P::Scalar) -> P
pub fn split(&self, t: P::Scalar) -> (Self, Self)
sourcepub fn distance_to_point(&self, p: P) -> P::Scalar
pub fn distance_to_point(&self, p: P) -> P::Scalar
Return the distance from the LineSegment to Point p by calculating the projection
sourcepub fn axis(&self, t: P::Scalar, axis: usize) -> P::Scalar
pub fn axis(&self, t: P::Scalar, axis: usize) -> P::Scalar
Sample the coordinate axis of the segment at t (expecting t between 0 and 1).
sourcepub fn derivative(&self) -> P
pub fn derivative(&self) -> P
Return the derivative function. The derivative is also a bezier curve but of degree n-1 - In the case of a line the derivative vector.
sourcepub fn bounding_box(&self) -> [(P::Scalar, P::Scalar); P::DIM]
pub fn bounding_box(&self) -> [(P::Scalar, P::Scalar); P::DIM]
Return the bounding box of the line as an array of (min, max) tuples for each dimension (its index)
