Struct wavefront::Vertex

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

A vertex defined in an OBJ.

Implementations

impl<'a> Vertex<'a>

pub fn position_index(&self) -> Index

Returns the index of the vertex's position in the slice given by Buffers::positions.

Note that, unlike OBJ files themselves, this is zero-indexed.

pub fn position(&self) -> [f32; 3]

Returns the position of this vertex.

pub fn uv_index(&self) -> Option<Index>

Returns the index of the vertex's texture coordinate, if it has one, in the slice given by Buffers::uvs.

Note that, unlike OBJ files themselves, this is zero-indexed.

pub fn uv(&self) -> Option<[f32; 3]>

Returns the texture coordinate of this vertex, if it has one.

pub fn normal_index(&self) -> Option<Index>

Returns the index of the vertex's normal, if it has one, in the slice given by Buffers::normals.

Note that, unlike OBJ files themselves, this is zero-indexed.

pub fn normal(&self) -> Option<[f32; 3]>

Returns the normal of this vertex, if it has one.

Trait Implementations

impl<'a> Clone for Vertex<'a>

pub fn clone(&self) -> Vertex<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Vertex<'a>

impl<'a> Debug for Vertex<'a>

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

Formats the value using the given formatter.
