Struct TriMesh 

pub struct TriMesh { /* private fields */ }

A closed, watertight, outward-oriented triangle mesh with welded vertices.

Implementations

impl TriMesh

pub fn from_triangles(soup: &[[[f64; 3]; 3]]) -> Result<Self, GeometryError>

Build from a triangle soup (counter-clockwise seen from outside), coordinates in metres. Welds vertices and runs the watertightness checks of the module docs.

pub fn from_stl(bytes: &[u8], unit_m: f64) -> Result<Self, GeometryError>

Parse an STL file (ASCII or binary), scaling coordinates by unit_m (metres per file unit).

pub fn from_obj(text: &str, unit_m: f64) -> Result<Self, GeometryError>

Parse a Wavefront OBJ file, scaling coordinates by unit_m (metres per file unit). Faces with more than three vertices are fan-triangulated.

pub fn vertices(&self) -> &[[f64; 3]]

Welded vertex positions, m.

pub fn triangles(&self) -> &[[u32; 3]]

Triangles as indices into TriMesh::vertices, counter-clockwise seen from outside.

pub fn volume_m3(&self) -> f64

Enclosed volume, m^3 (positive for an outward-oriented mesh).

pub fn bounds(&self) -> ([f64; 3], [f64; 3])

Axis-aligned bounds (min, max), m.
