Struct plexus::primitive::generate::Position

pub struct Position<S = ()> { /* private fields */ }

Meta-attribute for positions.

Describes the position of vertices in a polytope. The generated data is derived from the type parameter S, which typically requires EuclideanSpace.

Examples

Generating raw buffers with positional data of a cube:

use decorum::R64;
use nalgebra::Point3;
use plexus::index::{Flat3, HashIndexer};
use plexus::prelude::*;
use plexus::primitive::cube::Cube;
use plexus::primitive::generate::Position;
use plexus::primitive::UnboundedPolygon;

let (indices, positions) = Cube::new()
    .polygons::<Position<Point3<R64>>>()
    .triangulate()
    .index_vertices::<UnboundedPolygon<usize>, _>(HashIndexer::default());
