Struct quicksilver::graphics::ShapeRenderer

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

A way to render complex shapes using the lyon API

The ShapeRenderer has a color, transform, and z-ordering it applies to all incoming shapes. It outputs the shapes to a mutable Mesh reference, which can be a standalone mesh object or the one obtained by window.mesh()

Methods

impl<'a> ShapeRenderer<'a>

pub fn new(mesh: &'a mut Mesh, color: Color) -> ShapeRenderer<'a>

Create a shape renderer with a target mesh and an initial color

pub fn color(&self) -> Color

Get the current color of the incoming shapes

pub fn set_color(&mut self, color: Color)

Set the color of the incoming shapes

pub fn z(&self) -> f32

Get the Z position of the incoming shapes

pub fn set_z(&mut self, z: f32)

Set the Z position of the incoming shapes

pub fn transform(&self) -> Transform

Get the transformation that will be applied to all incoming shapes

pub fn set_transform(&mut self, trans: Transform)

Set the transformation that will be applied to all incoming shapes

Trait Implementations

impl<'a, Input> GeometryBuilder<Input> for ShapeRenderer<'a> where
    Color: VertexConstructor<Input, Vertex>, 

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_vertex(
    &mut self,
    vertex: Input
) -> 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.

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.
