Struct Mesh 

pub struct Mesh {
    pub origin: [f64; 2],
    pub lines: Vec<LineInstance>,
    pub fill_vertices: Vec<FillVertex>,
    pub fill_indices: Vec<u32>,
    pub glyphs: Vec<GlyphInstance>,
}

Tessellated geometry of one item or overlay.

Fields

origin: [f64; 2]

World origin of the local coordinates.

lines: Vec<LineInstance>

Line instances.

fill_vertices: Vec<FillVertex>

Fill vertices.

fill_indices: Vec<u32>

Fill triangle indices.

glyphs: Vec<GlyphInstance>

Glyph instances.

Implementations

impl Mesh

pub fn at(origin: [f64; 2]) -> Self

Empty mesh with an origin.

pub fn is_empty(&self) -> bool

Whether nothing would be drawn.

pub fn polyline( &mut self, points: &[Point], closed: bool, color: u32, width: f32, dash: [f32; 4], )

Append a stroked polyline (closed adds the closing segment).

pub fn fill_rings(&mut self, rings: &[Vec<Point>], color: u32)

Append filled rings (even-odd rule; holes are rings inside rings).

pub fn triangle(&mut self, a: Point, b: Point, c: Point, color: u32)

Append a filled triangle.

pub fn text(&mut self, ts: &mut TextSystem, t: &Text, color: u32) -> bool

Append laid-out text. Returns false if the glyph atlas was reset during layout (the caller re-tessellates everything with text).

Trait Implementations

impl Clone for Mesh

fn clone(&self) -> Mesh

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mesh

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

Formats the value using the given formatter.

impl Default for Mesh

fn default() -> Mesh

Returns the “default value” for a type.
