Struct MeshBuffer

pub struct MeshBuffer {
    pub anchor: Vec3,
    pub positions: Vec<[f32; 3]>,
    pub normals: Vec<[f32; 3]>,
    pub indices: Vec<u32>,
}

A shared triangle mesh, from usd::usdgeom::mesh.

Fields

anchor: Vec3

Local coordinates of the buffer’s zero: the centre of the mesh’s local bounding box. A vertex’s local position is anchor + position.

positions: Vec<[f32; 3]>

Vertex positions relative to anchor.

normals: Vec<[f32; 3]>

One unit normal per vertex, area-weighted over its triangles.

indices: Vec<u32>

Three indices per triangle, counter-clockwise front faces.

Implementations

impl MeshBuffer

pub fn triangle_count(&self) -> usize

Number of triangles.

Trait Implementations

impl Clone for MeshBuffer

fn clone(&self) -> MeshBuffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MeshBuffer

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

Formats the value using the given formatter.

impl PartialEq for MeshBuffer

fn eq(&self, other: &MeshBuffer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
