Struct StlMesh 

pub struct StlMesh {
    pub triangles: Vec<StlTriangle>,
    pub name: String,
}

An STL mesh consisting of named triangles.

Fields

triangles: Vec<StlTriangle>

The triangles that make up this mesh.

name: String

The name of the solid (used in ASCII output).

Implementations

impl StlMesh

pub fn new(name: &str) -> Self

Create a new empty STL mesh with the given name.

pub fn add_triangle(&mut self, v0: [f32; 3], v1: [f32; 3], v2: [f32; 3])

Add a triangle defined by three vertices; the normal is computed automatically.

pub fn to_binary_bytes(&self) -> Vec<u8>

Serialize this mesh to binary STL bytes.

Layout: 80-byte header + 4-byte little-endian triangle count + (12 floats + 2-byte attribute) per triangle = 50 bytes each.

pub fn from_binary_bytes(data: &[u8]) -> Result<Self, String>

Parse a binary STL byte slice into an StlMesh.

pub fn to_ascii(&self) -> String

Serialize this mesh to ASCII STL text.

pub fn from_ascii(s: &str) -> Result<Self, String>

Parse an ASCII STL string into an StlMesh.

pub fn surface_area(&self) -> f32

Compute the total surface area of this mesh.

pub fn bounding_box(&self) -> ([f32; 3], [f32; 3])

Compute the axis-aligned bounding box as (min, max).

Returns ([0.0;3], [0.0;3]) for an empty mesh.

pub fn is_watertight(&self) -> bool

Return true if every edge is shared by exactly two triangles (watertight).
