Implementations§

Source§

impl PathBuilder

Source

pub fn is_empty(&self) -> bool

Is the path empty or not

Source

pub fn new() -> Self

Construct a new path

Source

pub fn len(&self) -> usize

Get the number of points

Source

pub fn move_to(&mut self, point: DVec3) -> &mut Self

Starts a new subpath and push the point as the start_point

Source

fn assert_started(&self)

Source

pub fn line_to(&mut self, p: DVec3) -> &mut Self

Append a line

Source

pub fn quad_to(&mut self, h: DVec3, p: DVec3) -> &mut Self

Append a quadratic bezier

Source

pub fn cubic_to(&mut self, h1: DVec3, h2: DVec3, p: DVec3) -> &mut Self

Append a cubic bezier

Source

pub fn close_path(&mut self) -> &mut Self

Close the path.

The path is considered closed if the start point is equal to the last point.

If the path is not closed, a line is appended to the end to close it.

Source

pub fn vpoints(&self) -> &[DVec3]

Get the points
