Struct Mesh 

pub struct Mesh {
    pub vertices: Vec<Vertex>,
    pub indices: Vec<u32>,
}

A triangle mesh.

Fields

vertices: Vec<Vertex>

Vertex data.

indices: Vec<u32>

Triangle indices (3 per triangle).

Implementations

impl Mesh

pub fn new() -> Self

pub fn add_vertex(&mut self, vertex: Vertex) -> u32

Add a vertex and return its index.

pub fn add_triangle(&mut self, i0: u32, i1: u32, i2: u32)

Add a triangle by vertex indices.

pub fn add_quad(&mut self, i0: u32, i1: u32, i2: u32, i3: u32)

Add a quad (two triangles) by vertex indices. Vertices are provided in order around the quad. Triangles are wound CCW for front-facing.

pub fn add_quad_ao(&mut self, i0: u32, i1: u32, i2: u32, i3: u32, ao: [u8; 4])

Add a quad with AO-aware triangulation to fix anisotropy. Uses the diagonal that minimizes interpolation artifacts.

pub fn triangle_count(&self) -> usize

Get the number of triangles.

pub fn vertex_count(&self) -> usize

Get the number of vertices.

pub fn is_empty(&self) -> bool

Check if the mesh is empty.

pub fn merge(&mut self, other: &Mesh)

Merge another mesh into this one.

pub fn translate(&mut self, offset: [f32; 3])

Translate all vertices by an offset.

pub fn positions_flat(&self) -> Vec<f32>

Get positions as a flat array (for glTF export).

pub fn normals_flat(&self) -> Vec<f32>

Get normals as a flat array (for glTF export).

pub fn uvs_flat(&self) -> Vec<f32>

Get UVs as a flat array (for glTF export).

pub fn colors_flat(&self) -> Vec<f32>

Get colors as a flat array (for glTF export).

Trait Implementations

impl Clone for Mesh

fn clone(&self) -> Mesh

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mesh

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

Formats the value using the given formatter.

impl Default for Mesh

fn default() -> Mesh

Returns the “default value” for a type.
