Struct nannou::draw::mesh::intermediary::IntermediaryMeshBuilder

pub struct IntermediaryMeshBuilder<'a, S = Default> { /* fields omitted */ }

A lyon::GeometryBuilder around the IntermediaryMesh type.

Methods

impl<'a, S> IntermediaryMeshBuilder<'a, S>

pub fn vertex_data_ranges(&self) -> IntermediaryVertexDataRanges

pub fn index_range(&self) -> Range<usize>

pub fn min_index(&self) -> usize

The minimum index that exists within the index range.

Trait Implementations

impl<'a, S: Debug> Debug for IntermediaryMeshBuilder<'a, S>

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

Formats the value using the given formatter.

impl<'a, V, S> GeometryBuilder<V> for IntermediaryMeshBuilder<'a, S> where
    V: IntermediaryVertex<S>, 

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, v: V) -> 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.
