Struct ObjMesh 

pub struct ObjMesh {
    pub vertices: Vec<[f64; 3]>,
    pub normals: Vec<[f64; 3]>,
    pub uvs: Vec<[f64; 2]>,
    pub faces: Vec<ObjFace>,
    pub groups: Vec<ObjGroup>,
}

A Wavefront OBJ mesh with vertices, normals, UVs, and faces.

Fields

vertices: Vec<[f64; 3]>

3D vertex positions.

normals: Vec<[f64; 3]>

Per-vertex normals.

uvs: Vec<[f64; 2]>

UV (texture) coordinates.

faces: Vec<ObjFace>

Face list.

groups: Vec<ObjGroup>

Named groups.

Implementations

impl ObjMesh

pub fn to_triangle_soup(&self) -> Vec<[[f64; 3]; 3]>

Extract a flat triangle soup from the mesh.

Each triangle is [[v0\], [v1], [v2]] in world-space coordinates. Quad faces are triangulated as (0,1,2) and (0,2,3).

pub fn faces_in_group(&self, group_name: &str) -> Vec<&ObjFace>

Return faces belonging to a specific group.

pub fn faces_in_smoothing_group(&self, sg: u32) -> Vec<&ObjFace>

Return faces belonging to a specific smoothing group.

pub fn faces_with_material(&self, mat_name: &str) -> Vec<&ObjFace>

Return faces with a specific material.

pub fn triangle_count(&self) -> usize

Total number of triangles after fan-triangulation.

pub fn face_normal(&self, face_idx: usize) -> Option<[f64; 3]>

Compute flat face normal for a triangular face.

pub fn bounding_box(&self) -> Option<([f64; 3], [f64; 3])>

Compute axis-aligned bounding box of all vertices.

Trait Implementations

impl Clone for ObjMesh

fn clone(&self) -> ObjMesh

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjMesh

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

Formats the value using the given formatter.

impl Default for ObjMesh

fn default() -> ObjMesh

Returns the “default value” for a type.
