Struct ShapeRenderer

pub struct ShapeRenderer<'a> { /* private fields */ }

A way to render complex shapes using the lyon API

Implementations

impl<'a> ShapeRenderer<'a>

pub fn new(mesh: &'a mut AbstractMesh) -> ShapeRenderer<'a>

Create a shape renderer with a target mesh

Trait Implementations

impl<'a> FillGeometryBuilder for ShapeRenderer<'a>

fn add_fill_vertex( &mut self, vertex: FillVertex<'_>, ) -> Result<VertexId, GeometryBuilderError>

Inserts a vertex, providing its position, and optionally a normal. Returns a vertex id that is only valid between begin_geometry and end_geometry.

impl<'a> GeometryBuilder for ShapeRenderer<'a>

fn begin_geometry(&mut self)

Called at the beginning of a generation.

fn end_geometry(&mut self) -> Count

Called at the end of a generation. Returns the number of vertices and indices added since the last time begin_geometry was called.

fn add_triangle(&mut self, a: VertexId, b: VertexId, c: VertexId)

Insert a triangle made of vertices that were added after the last call to begin_geometry.

fn abort_geometry(&mut self)

abort_geometry is called instead of end_geometry if an error occurred while producing the geometry and we won’t be able to finish.

impl<'a> StrokeGeometryBuilder for ShapeRenderer<'a>

fn add_stroke_vertex( &mut self, vertex: StrokeVertex<'_, '_>, ) -> Result<VertexId, GeometryBuilderError>

Inserts a vertex, providing its position, and optionally a normal. Returns a vertex id that is only valid between begin_geometry and end_geometry.
