Struct TriMesh 

pub struct TriMesh {
    pub vertices: Vec<f32>,
    pub indices: Vec<i32>,
    pub vert_count: usize,
    pub tri_count: usize,
}

A simple triangle mesh

Fields

vertices: Vec<f32>

Flat array of [x, y, z] coordinates

indices: Vec<i32>

Triangle indices, 3 per triangle

vert_count: usize

tri_count: usize

Implementations

impl TriMesh

pub fn new() -> Self

Creates a new empty triangle mesh

pub fn from_obj<P: AsRef<Path>>(path: P) -> Result<Self, MeshError>

Loads a mesh from an OBJ file

This method is only available when the std feature is enabled.

pub fn from_obj_str(content: &str) -> Result<Self, MeshError>

Parses OBJ content from a string

This method is WASM-compatible and can parse OBJ data that has been loaded into memory through other means (e.g., fetch API in browser).

Example

use landmark_common::TriMesh;

let obj_content = r#"
v 0.0 0.0 0.0
v 1.0 0.0 0.0
v 0.5 1.0 0.0
f 1 2 3
"#;

let mesh = TriMesh::from_obj_str(obj_content).unwrap();
assert_eq!(mesh.vert_count, 3);
assert_eq!(mesh.tri_count, 1);

pub fn calculate_bounds(&self) -> (Vec3, Vec3)

Calculates the axis-aligned bounding box of the mesh

Trait Implementations

impl Clone for TriMesh

fn clone(&self) -> TriMesh

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TriMesh

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

Formats the value using the given formatter.

impl Default for TriMesh

fn default() -> TriMesh

Returns the “default value” for a type.
