Implementations

impl<'a> MeshBuilder<'a, SingleColor>

pub fn single_color(mesh: &'a mut Mesh, transform: Mat4, color: Color) -> Self

Begin extending a mesh rendered with a single colour.

impl<'a> MeshBuilder<'a, ColorPerPoint>

pub fn color_per_point(mesh: &'a mut Mesh, transform: Mat4) -> Self

Begin extending a mesh where the path interpolates a unique color per point.

impl<'a> MeshBuilder<'a, TexCoordsPerPoint>

pub fn tex_coords_per_point(mesh: &'a mut Mesh, transform: Mat4) -> Self

Begin extending a mesh where the path interpolates a unique texture coordinates per point.

Trait Implementations

impl<'a> FillGeometryBuilder for MeshBuilder<'a, SingleColor>

fn add_fill_vertex(
    &mut self,
    position: Point,
    _attrs: FillAttributes<'_>
) -> 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> FillGeometryBuilder for MeshBuilder<'a, ColorPerPoint>

fn add_fill_vertex(
    &mut self,
    position: Point,
    attrs: FillAttributes<'_>
) -> 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> FillGeometryBuilder for MeshBuilder<'a, TexCoordsPerPoint>

fn add_fill_vertex(
    &mut self,
    position: Point,
    attrs: FillAttributes<'_>
) -> 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, A> GeometryBuilder for MeshBuilder<'a, 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 MeshBuilder<'a, SingleColor>

fn add_stroke_vertex(
    &mut self,
    position: Point,
    _attrs: StrokeAttributes<'_, '_>
) -> 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> StrokeGeometryBuilder for MeshBuilder<'a, ColorPerPoint>

fn add_stroke_vertex(
    &mut self,
    position: Point,
    attrs: StrokeAttributes<'_, '_>
) -> 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> StrokeGeometryBuilder for MeshBuilder<'a, TexCoordsPerPoint>

fn add_stroke_vertex(
    &mut self,
    position: Point,
    attrs: StrokeAttributes<'_, '_>
) -> 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.
