Fields

vertices: &'a [[f32; 3]]

faces: &'a [[usize; 3]]

colors: &'a [Rgb565]

lines: &'a [[usize; 2]]

normals: &'a [[f32; 3]]

vertex_normals: &'a [[f32; 3]]

Per-vertex normals for smooth (Gouraud) shading. If non-empty, must have the same length as vertices.

uvs: &'a [[f32; 2]]

UV texture coordinates (one per vertex)

texture_id: Option<u32>

Optional texture ID for this geometry

Implementations

impl Geometry<'_>

pub fn lines_from_faces<const N: usize>( faces: &[[usize; 3]], ) -> Vec<(usize, usize), N>

Converts faces to unique edge pairs for line rendering.

Type Parameters

• N - Maximum capacity for the edges buffer. For a closed mesh, a good estimate is faces.len() * 3 / 2 since each edge is typically shared by 2 faces.

Returns

A heapless Vec containing unique edge pairs. If capacity is exceeded, returns partial results with an error logged.

Trait Implementations

impl<'a> Clone for Geometry<'a>

fn clone(&self) -> Geometry<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Geometry<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Geometry<'a>

fn default() -> Geometry<'a>

Returns the “default value” for a type.
