Struct ModelMesh 

pub struct ModelMesh {
    pub positions: Vec<[f32; 3]>,
    pub normals: Vec<[f32; 3]>,
    pub uvs: Vec<[f32; 2]>,
    pub indices: Vec<u32>,
}

A lightweight mesh representation loaded from a 3D model file.

Fields

positions: Vec<[f32; 3]>

Vertex positions [x, y, z].

normals: Vec<[f32; 3]>

Vertex normals [nx, ny, nz].

uvs: Vec<[f32; 2]>

Texture coordinates [u, v].

indices: Vec<u32>

Triangle indices.

Implementations

impl ModelMesh

pub fn from_gltf(bytes: &[u8]) -> Result<Self, ModelLoadError>

Load the first mesh from a glTF binary (.glb) or JSON (.gltf) buffer.

Extracts positions, normals, texture coordinates, and triangle indices from the first primitive of the first mesh in the file. Missing normals default to [0, 0, 1]; missing UVs default to [0, 0].

Errors

Returns ModelLoadError::Parse if the glTF data is malformed, or ModelLoadError::NoMesh if the file contains no mesh primitives.

impl ModelMesh

pub fn from_obj(bytes: &[u8]) -> Result<Self, ModelLoadError>

Load the first mesh from a Wavefront OBJ buffer.

Parses the OBJ data (no MTL material support). Extracts positions, normals, and texture coordinates from the first model. Missing normals default to [0, 0, 1]; missing UVs default to [0, 0].

Errors

Returns ModelLoadError::Parse if the OBJ data is malformed, or ModelLoadError::NoMesh if the file contains no models.

Trait Implementations

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

impl Debug for ModelMesh

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

Formats the value using the given formatter.
