Struct centerline::Centerline

pub struct Centerline<I, F> where
    I: InputType + Neg<Output = I>,
    F: BaseFloat + Sync + OutputType + Neg<Output = F>,  {
    pub segments: Vec<Line<I>>,
    pub diagram: SyncDiagram<I, F>,
    pub lines: Option<Vec<Line3<F>>>,
    pub line_strings: Option<Vec<LineString3<F>>>,
    // some fields omitted
}

Center line calculation object. It: * calculates the segmented voronoi diagram. * Filter out voronoi edges based on the angle to input geometry. * Collects connected edges into line strings and line segments. * Performs line simplification on those line strings.

Fields

segments: Vec<Line<I>>

the input data to the voronoi diagram

diagram: SyncDiagram<I, F>

the voronoi diagram itself

lines: Option<Vec<Line3<F>>>

the individual two-point edges

line_strings: Option<Vec<LineString3<F>>>

concatenated connected edges

Implementations

impl<I, F> Centerline<I, F> where
    I: InputType + Neg<Output = I>,
    F: BaseFloat + Sync + OutputType + Neg<Output = F>, 

pub fn default() -> Self

Creates a Centerline container with a set of segments

pub fn with_segments(segments: Vec<Line<I>>) -> Self

Creates a Centerline container with a set of segments

pub fn build_voronoi(&mut self) -> Result<(), CenterlineError>

builds the voronoi diagram and filter out infinite edges and other ‘outside’ geometry

pub fn calculate_centerline(
    &mut self,
    cos_angle: F,
    discrete_limit: F,
    ignored_regions: Option<&Vec<(Aabb2<F>, LineString2<F>)>>
) -> Result<(), CenterlineError>

perform the angle-to-geometry test and filter out some edges. Collect the rest of the edges into connected line-strings and line segments.

pub fn calculate_centerline_mesh(
    &mut self,
    discrete_limit: F,
    ignored_regions: Option<&Vec<(Aabb2<F>, LineString2<F>)>>
) -> Result<(), CenterlineError>

Collects lines and linestrings from the centerline. This version of calculate_centerline() tries to keep as many edges as possible. The intention is to use the data for mesh generation. TODO: make this return a true mesh

pub fn ignored_edges(&self) -> Option<Yabf>

returns a copy of the ignored edges bit field

pub fn rejected_edges(&self) -> Option<Yabf>

returns a copy of the rejected edges bit field

pub fn retrieve_point(
    &self,
    cell_id: CellIndex
) -> Result<Point<I>, CenterlineError>

pub fn retrieve_segment(
    &self,
    cell_id: CellIndex
) -> Result<Line<I>, CenterlineError>

pub fn diagram(&self) -> &SyncDiagram<I, F>

returns a reference to the internal voronoi diagram

pub fn i2f(input: I) -> F
