Expand description

Functions for collecting an iterator of $n$-gons into a mesh data structure.

These functions can be used to collect data from an iterator into mesh data structures like MeshBuffer or MeshGraph.

See HashIndexer and LruIndexer.

Required Methods

source

fn collect_with_indexer<T, N>(self, indexer: N) -> Result<T, T::Error> where
T: FromIndexer<P, Q>,
N: Indexer<Q, P::Vertex>,

Collects an iterator of $n$-gons into a mesh data structure using the given indexer.

Unlike collect, this function allows the indexer to be specified.

Errors

Returns an error defined by the implementer if the target type cannot be constructed from the indexed vertex data.

Examples

use decorum::R64;
use nalgebra::Point3;
use plexus::graph::MeshGraph;
use plexus::prelude::*;
use plexus::primitive::cube::Cube;
use plexus::primitive::generate::Position;
use plexus::index::HashIndexer;

let graph: MeshGraph<Point3<f64>> = Cube::new()
    .polygons::<Position<Point3<R64>>>()
    .collect_with_indexer(HashIndexer::default())
    .unwrap();
