Struct 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 Face

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

Create a new face with the given indices and ColChar

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

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

Errors

Will return an error if the passed slice is not long enough to be indexed by the face
