Struct ParamTriMesh 

pub struct ParamTriMesh {
    pub positions: Vec<[f64; 3]>,
    pub uvs: Vec<[f64; 2]>,
    pub normals: Vec<[f64; 3]>,
    pub triangles: Vec<[usize; 3]>,
}

A triangle mesh with UV coordinates and normals, used for parameterization.

Note: This is distinct from mesh_ops::TriMesh which uses nalgebra Vec3.

Fields

positions: Vec<[f64; 3]>

3D positions of vertices.

uvs: Vec<[f64; 2]>

UV texture coordinates per vertex.

normals: Vec<[f64; 3]>

Per-vertex normals.

triangles: Vec<[usize; 3]>

Triangle indices.

Implementations

impl ParamTriMesh

pub fn new() -> Self
