Struct shape_core::TriangleIndex

pub struct TriangleIndex {
    pub a: usize,
    pub b: usize,
    pub c: usize,
}

Clockwise means the front side, and counterclockwise means the back side. When rendering, only the front side is rendered by default, and the back side is invisible.

If you need double-sided display, you need to draw the reverse side at the same time, you can call !self to get the reverse side

Fields

a: usize

The 1st vertex in the triangle index.

b: usize

The 2nd vertex in the triangle index.

c: usize

The 3rd vertex in the triangle index.
