Struct Mesh 

pub struct Mesh {
    pub name: String,
    pub positions: Vec<V3>,
    pub normals: Option<Vec<V3>>,
    pub colors: Option<Vec<V3>>,
    pub indices: Vec<u32>,
    pub material: Option<Material>,
    pub uvs: Option<Vec<[f32; 2]>>,
    pub texture: Option<Texture>,
    pub surface: Surface,
}

One part of a model: triangles over shared vertices, drawn in one material.

Fields

name: String

positions: Vec<V3>

normals: Option<Vec<V3>>

Normals from the file, one per position, when it has them.

colors: Option<Vec<V3>>

Vertex colours (0..1), one per position, when the file has them; they replace the material colour.

indices: Vec<u32>

Three indices into positions per triangle.

material: Option<Material>

uvs: Option<Vec<[f32; 2]>>

Texture coordinates, one per position, in picture space (u right, v down; see texture), when the file has them.

texture: Option<Texture>

The material’s texture, drawn where the mesh has uvs; otherwise (and where the picture couldn’t be read) the material colour is.

surface: Surface

What the material adds to its colour and picture.

Implementations

impl Mesh

pub fn triangle_count(&self) -> usize

pub fn sanitize(&mut self)

Drops triangles that point past the vertices and lists that are not one per vertex, so the rest of the code can index freely.

pub fn textured(&self) -> Option<(&Texture, &[[f32; 2]])>

The texture and coordinates to draw with, when the mesh has both.

pub fn opacity(&self) -> f32

The alpha the material gives every pixel: its opacity when it is drawn see-through, otherwise 1.

pub fn has_look(&self) -> bool

Whether the plain colour pipeline can’t draw it: it has a picture, a map, its own light or transparency.

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.

impl PartialEq for Mesh

fn eq(&self, other: &Mesh) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
