Struct centerline::Centerline

pub struct Centerline<I: InputType, T: GenericVector3>
where
    T::Scalar: OutputType,
{
    pub segments: Vec<Line<I>>,
    pub diagram: SyncDiagram<T::Scalar>,

    /* private fields */
}

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<T::Scalar>

the voronoi diagram itself

lines: Option<Vec<Line3<T>>>

the individual two-point edges

line_strings: Option<Vec<Vec<T>>>

concatenated connected edges

Implementations

impl<I, T3: GenericVector3> Centerline<I, T3>

where T3::Scalar: OutputType, I: AsPrimitive<T3::Scalar> + InputType,

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: T3::Scalar, discrete_limit: T3::Scalar, ignored_regions: Option<&Vec<(Aabb2<T3::Vector2>, Vec<T3::Vector2>)>> ) -> 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: T3::Scalar, ignored_regions: Option<&Vec<(Aabb2<T3::Vector2>, Vec<T3::Vector2>)>> ) -> 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<Vob<u32>>

returns a copy of the ignored edges bit field

pub fn rejected_edges(&self) -> Option<Vob<u32>>

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<T3::Scalar>

returns a reference to the internal voronoi diagram

impl<I: InputType, T3: GenericVector3> Default for Centerline<I, T3>

where T3::Scalar: OutputType,

fn default() -> Self

Creates a Centerline container with a set of segments
