[−][src]Struct wavefront::Polygon

pub struct Polygon<'a> { /* fields omitted */ }

A polygon defined in an OBJ.

Implementations

impl<'a> Polygon<'a>[src]

pub fn vertex(&self, index: usize) -> Option<Vertex<'a>>[src]

Returns a specific Vertex by index.

pub fn vertices(&self) -> impl ExactSizeIterator<Item = Vertex<'a>> + Clone + 'a[src]

Returns an iterator over the Vertexs in this Polygon.

pub fn triangles(
    &self
) -> impl ExactSizeIterator<Item = [Vertex<'a>; 3]> + Clone + 'a[src]

Returns an iterator over triangles in this Polygon by splitting up the polygon into smaller pieces.

This function is useful when your application supports only triangles as input but the OBJ contains unusual polygons such as quads.

The triangles produced will be arranged in a fan and will follow the winding order of the original polygon.

This function assumes that:

  • The polygon is concave
  • The vertices of the polygon all lie in the same plane
