Enum VertexMode 

pub enum VertexMode {
    Triangles,
    TriangleStrip,
    TriangleFan,
}

How positions are grouped into triangles.

The two compact forms exist because a strip or a fan states a triangle in one vertex where a list states it in three, and a caller who has that shape already should not have to expand it. They are expanded here rather than carried to a backend, since the difference is an index buffer and both backends draw indexed triangles.

Variants

Triangles

Every three positions are one triangle.

TriangleStrip

Each position after the second closes a triangle with the two before it, alternating winding so the strip is consistently wound.

TriangleFan

Each position after the second closes a triangle with the first and the one before it.
