Struct gemini_engine::elements3d::view3d::Face

pub struct Face {
    pub v_indices: Vec<usize>,
    pub fill_char: ColChar,
}

A Face contains indices to a mesh’s collection of vertices and a ColChar to fill the face. Indices should be arranged in a clockwise order, as if they appear counter-clockwise when rendering they will not be rendered at all (this is how gemini-engine handles backface culling and maximises performance)

Fields

v_indices: Vec<usize>

The vertex indices of the face

fill_char: ColChar

The desired appearance of the face when rendered

Implementations

impl IndexFace

pub const fn new(v_indices: Vec<usize>, fill_char: ColChar) -> Self

Create a new face with the given indexes and ColChar

pub fn index_into<T: Copy>(&self, vertices: &[T]) -> Vec<T>

Returns a vector with the elements found at the vertex indices of the given slice

Trait Implementations

impl Clone for IndexFace

fn clone(&self) -> IndexFace

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IndexFace

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

Formats the value using the given formatter.
